ABSTRACT: Tile paper deals with the application of the game theory to theoretically
simplest sampled data control systems, for which sets of possible disturbances and
possible control signals were computed using a finite number of elements. In
particular, the problem of determining by the game theory an optimal control for
sampled data controls with unknown probability distributions of disturbances was
investigated. Methods of establishing an optimal probabilit distribution of the

were given and illustrated by several examples. Application of the game theory as
discussed in the paper fits optimization when control evaluation is done for one
stage, and for an optimal disturbance compensation. Orig. art. has: 7 figures,
3 tables, and 27 formulas. [Based on author's abstract)

be satisfied: k < n-2 for n > 2 and any k _N 0 for n = 1,2; the
stability is independent of the time aDnstant. Stability of a system con-
sisting of elements of higher order capacitance depends on gain and time
constants. There are no ready rules for stability of a system consisting
of a3tatic elements. There are 4 figures and 4 references: 2Soviet-bloc

ABSTRACT The Chinese Academy of Science worked out a plan for scientific
work to be accomplished within the next 12 years. The major part
of this work-shall be devoted to problems of Chemistry and the
technology of silicates. Several now scientific institutes are
intended to be founded for this purpose the main task of which
will be the investigation of various oxides, vitreous substances,
and silicate raw materials for the purpose of developing the
silicate industry.
The Chinese Peoples' Republic has vast stocks of various
valuable silicate materials which have as yet not been scienti-
fically exploited. Chinese kaolin earths are world famous is*,also
such materials as "porcelain stone" and *east glass stone" in
which field research work will be of great importance for
Chinese industry. The same may be said about quartzp taloumv
gypsum, serpentine, and other materials available in China.

The main oenter of research is The Institute for Metallurgy and
Ceramics of the Academy of Science at Shanghai with branches
at Tshansha and Xurimin. The institute is under the management
of professor Chshou-Zhen and has a staff of 300 persons. Apart
from experimental stations the institute also possesses
industrial objects such as blast furnaces for gray cast iron.
Particular succesa-wan attained by this institute in the field
of the production of fireproof articles, special glaBs such
an electrovacuuii glass, glass'for steam boilers, special barium
lass which allows only ultraviolet rays to pass (at 3000-4000
) whilst*nearly all others are aboorbedp baseproof boron

A second institute of equal importance is at Nukden (under the
management of Prof. Li-Siu-1n) which has 6 departments:
enrichment of or*, science of firproofnesso metallurgical
chemistry, metal working, metal physics, and analytical
chemistry. Further, there is the Institute for the metalurgy
of casting and the Institute for building material. Furthery
there is the great central laboratory of the Anshan industrial
combine, the Institute for Ceramics at Taindeahzhen and
others. It was here that at the time of the Hin dynasty
(1368-1644) the porcelain industry was establishedp which was

under the protection of the emperors and aroused the admiration
of the entire world. It must be mentioned that, apart from
scientifically founded industry, which in making enormous
progress at the timep the branches of the old established
primitive home industry are still prospering in China the
products of which are distinguished by their superb and
precise workmanship and hand-painted decorations, particularly
as far an chinaware.(poreelain) is concerned. This circumstance
decided the Chinese government to establish a now high school
for the Technology of Lrtistie products an& ceramics and to
found a special Institute for the Resarch of Applied Art in
Antiquity and Present.

ABSTRACT: To refill the engine-5tarting' compressed air containers of a new
83230R diesel the above-mention6d contAiners were usually sent to a special
compressor station. Since this operation was taking too much time, the
Frolovskays prospecting office of the Stalingradneftegaz rezvedka Trust decided
to ittilize the V2-300 diesel engine which drives a winch. For this purpose
the starting valve of the V2-300 diesel has been remodeled as shown in a
sketch and described by the author. He also explains how the remodeled V2-300
diesel engine operates and refills the compressed air engine-starting con-
tainer in 35-40 minutes. Daring this time the V2-)Oo engine has to operate
continuously. The utilization of remodeled V2-300 engines for refilling
the engine-starting compressed air roatainers of a 8523OR engine mOms it pos-
sible to start the drilling rig eaiily and as soon as needed.

ABSTRACT: The economics of agricultural production and the soil-
climate variations of the district were studied during
the process of dividing the district into natural and
economic-agricultural zones. Collective farm production
was estimated by administrative districts (AD), state
farm production in terms of individual products and
specialized product groups. This resulted in 38 AD!s
which were divided into three zones (groups) of similar
Card 1/2 units raising similar products. 1), A group of ten AD's

in the northwest., These grow cereals, numerous winter crops, sun-
flowers and beets, and also raise cattle and pigs for milk and meat.
2) A group comprising 13 AD's in the northwest. These raise beets,
cereals, and pigs. They also produce winter crops. 3) A group
comprising 15 AD's which raise cereals and cattle. Here the bulk
of the planting is spring wheat, and cattle and sheep are raised for
milk and meat. The article contains a brief description of the basic
indices of agricultural economy for each group and an outline map
of the area.

ABSTRACT: Of late great interest has been shown in the above mentioned
systems as they are used as initiators of the polymerization
of certain olefines. It had to be assumed that the primary
interaction of\ the molecules of compounds belonging to the
initiator finds its expression in the bimolecular reaction
with simultaneo-ds formation of a free radical
R3Al + TiCl 4 --.N R + AlClR 2 + TiCl 3'
This reaction, as it is, can not be classified as a usual
Card 1/3 one as the polymerization in many a respect is different

from the usual free-radioal one.It is, apart from other
properties, of a heterogenous character. It could be assumed
that the primary formation of the radicals would have on
affect on the nature of the (forming) heterogenous catalyst.
The authors of this latter found an electron paramagnetic
resonance with a g-factor around 2. In the system
Al (i-C 4H9)3 -TiCl4, for instance, a resonance absorption can
be observed at room temperature. The reaction products
TiCl4 with Al(C2 H5)3 and Al(G2H 5)3 , also show a tendency to
paramagnetic resonance. The presence of a resonance
absorption proves that radicals are formed. It is assumed
that these radicals are connected with the process or the
flow polymerization in a peculiar way.

ABSTRACT: References are made in publications to free radicals formed
during the action of ionizing radiation, as by X-rays, y-
radiation, fast electrons etc. This is caused by a rupture of
C - C and of C - H bindines. When fluid hydrocarbons are
radiolysed, the life of the free radicals is very short. The
main products of radiolysis, apart from liquid products with
one or two conjugated double bindings, are H 2 and C14H3o . The
latter compound is considered to be a dimer of the heptyl
radical. The method of determining the radical is shortly
Card 1/3 described. The following hydrocarbons were investig--,ted: hexane,

heptane, octane, dodecanet cetane, isooctane, cyclohexane~
benzene and toluene. In all cases intensive signals of para-
magnetic electron resonance with a g-factor of,-j 2,0 are
observed. In paraffin-type hydrocarbons and in cyclohexane a
hyperfine structure was very clearly observed. According to
the attached photographs the hyperfine structure is considerably
changed if the structural properties of the initial molecule
change. Another peculiarity of the spectra pf paramagnetic
electron resonance of the hydrocarbons which are irradiated in
a frozen state is the existence of considerable concentrations
of hydrogen atoms. This is also indicated by two narrow signals
which are located symmetrically at a distance of about 250
Oersted (Ersted) from the signals of the alkyl radical. The
hydrogen atoms probably do not become stabilized in the volume
of the frozen hydrocarbons but on the internal surface of the
quartz ampoule. In a table the quantitative measurements per-
formed on the basis of the example of heptane concerning the
concentration of the free radicals with a dose of-., io7r are

ABSTRACT: According to K. Ziegler et al. (Ref 1), the inverse reaction
of the recombination of triphenylmethyl radicals must proceed
with an activation energy which is equal to the difference
between the activation energy of the dissociation and the dis-
sociation heat of hexaphenylethane (6 - 8 kcal). By the
method of paramagnetic electron resonance, this conclusion
could be confirmed by immediate measuring of the dimerization rate
of triphenylmethyl radicals in the solution. A capillary with
a olution of hexaphenylethane in toluene was heated to 100 0
and then it was rapidly cooled down to the temperature of
the experiment. This operation was carried out in a thermo-
Card 1/3 stat which -was placed within the resonator of the EFR -spectro-

meter. In this way, noticeable superequilibrium concentrations
of the triDhenylmethyl radicals were obtained, and their
recombinatlon rate could be measured. The carrying out of
the experiments is discussed in short. A figure shows 2
kinetic curves of the recombination of triphenylmethyl radicals
at -640 and -350. The recombination rate increases noticeably
with temperature. An equation for the kinetics of the radical
recombination is given, the inverse reaction is taken into
account. The second diagram demonstrates the temperature
dependence of the equilibrium constant and the third diagram
shows the temperature dependence of the constant of the di-
merization rate. The Arrhenius (Arrenius) dependence is well
satisfied. Thus, the direct determination of the dimerization
rate of triphenylmethyl radicals confirmed not only the existence
of an activation energy of this reaction but also its value
(which coincides with the difference between the activation
energy of the dissociation and the energy necessary for the
breaking of the C-C bond of hexaphenyl ethane . The authors

as well as with the mechanism of chemical transformations
in solid organic bodies under the influence of ionizing radia-
tion. Polyethylene, polyvinyl chloride, "Teflon" (polyethylezB

methyl metbacrylate and natural rubber were investigated. 0 Car-

The Investigation of the Spectra of the ElectranParamarnetic Resonance of

with a g-factor near 2.0036 was observed in all samples. After
"thawing" of the sample down to room temperature the signal
was in all cases found to chanee. In some cases, the signal
vanished completely as a result of "thawing" (polyisobutyleneq
polydimethyl siloxane, natural rubber). In the case of other
materials the character bf the signal and its fine structure
changed considerably. A comparison of all data obtained gave
the following result: The character of the spectra obtained
by investigating not "thawed" samples can be fully explained
by the assumption that the predominant primary chemical act
in irradiation is the stripping of one of the C-H bonds in
the main chain (or in the absence of a main chain the strip-
ping of a C-H bond in a lateral chain). The spectrum of
paramagnetic electron resonanne recorded at 77 0K consists of
6 components. The even number of the spectrum in this as well
as in other cases is connected with the formation of the radi-
cal -Ch 2- CII-CHi- . The authors then discuss several details,

ABSTRACT: The authors first mention some previous papers on this subject.
They investigated the interaction of tripheny1chloromethane
with ethyl lithium, the first act of which must be exothermic
if it proceeds according to the scheme. The reaction was car-
ried out in a thin-walled test tube which was placed in the
resonator of a EPR-spectrometer. In this reaction radicals
mere actually observed. The hyperfine spectrum of these radicals
exactly corresponds to the spectrum of absorption of triphenyl-
methyl radicals. A diagram shows the kinetic curves for the varia-
tion of the concentration of triphenylmethyl radicals in the
course of the reaction at -44, -54, and -80 0. In the first
instant of the reaction, the concentration has a distinctly
marked maximum and it decreases behind this maximum. The des-
Card 1/3 cending parts of the curve represent the recombination of the

the reaction. The experimental results prove the primary
formation of the above-mentioned radicals. The maximum of the
kinetic curves is not caused by an increase in temperature of
the reaction mixture. The character of the kinetic curves
corresponds to an accumulation of the intermediate product
in the successivebbdecular reactions. The constants of velocity
and the activation "energy of the reaction of radical formation
can be calculated from the kinetic curves fuund in this paper.
According to these results, elementary reactions of the type

can proceed with the formation of free radicals of insig-
nificant energy. It has hitherto not been possible to generalize

ABSTRACT: The spectrometer is of the double field modulation type,
with automatic frequency control (APO) applied to the klystron.
The APO signal is obtained by applying about 15 mV at 630 kc/s
to the reflector of the 3.2 cm klystron; the resulting output
signal is amplified and is detected by a phase-sensitive de-
tector, and thus gives a control signal, which is used to
tune the klystron automatically over a range of about 60 Mals.
The second field modulation kat 975 kc/s) is produced by
using a coil carrying about 40 A outside the cavity, which
has 2.5 mm slots in it; these slots reduce the Q from
about 10 000 to about 8000. The field produced by this
coil at the centre of the ca-VIty is about 2 oersted. The
sensitivity is about 4 x 10--LIJ mole of diphenylpierylhydrazyl
at 770K. Fig 1 shows the block diagram; Fig 2 is a general

ABSTRACT: The usual magnetic radiospectrometers are very sensitive to the
slightest mechanical oscillations and temperature changes and
require tiresome adjustment before each measurement, which
renders their application for the solution of various chemical
problems very difficult. In order to overcome these difficulties,
some types of magnetic radiospectrometers were designed and
tested by the Institut khimicheskoy fiziki Akademii nauk SSSR
(Institute of Chemical Physics of the Academy of Sciences, USSR).
A radiospectrometer wi-th a transmission resonator, automatic
adjustment of the frequency of the klystron generator and a
high-frequency modulation of the magnetic field proved to be
best. It.is easily operable, sensitive and, compared to other

of the hydrocarbon in its homologous series. Fig 1 shows the spectra
of radicals of normal paraffin hydrocarbons fran CllH23 to Clb'i33

another. In even hydrocarbons the resolution is much poorer and the
intensity distribution is close to binomial. In paraffin hydrocarbons

ABSTRACT: It was reported (Refs 1, 2) that H atoms, formed on x-irradiation of
frozen hydrocarbons and other compounds, can be stalgized on various
surfaces. The present paper reports studies of the effect of the
nature of the stalUizing surface on the magnitude of h.f.s. splitting

the width of the o.p.r. absorption lines - The H atoms -were stabilized

irradiation of these three substances with x-rays at 77oK. It may
be assumed that formation of H atoms is due to rupture or bonds in
E20 molecules adsorbed on these surfaces or rupture of bonds in SiOH
groups (Ref 3). -the magnitude of h.f.s. splitting in all the three
cases was found to be close to 500 oersted which does not differ great!y
from splitting in a free H atom (Rer 4). Width of the comDonents of the
hydrogen doublet depends strongly on the nature of the surfaces on

quartz it is close to 0.8 oersted tcurve I in a figure on p 566), on
silica gal it is near 2.4 oersted (curve 2) and on molybdenum glass it
is 4.5 oersted keurve 3). Since the hyperfine splitting in the e.p.r.
spectra of H atoms stabilized on various surfaces is close to the
hyperfine splitting of free atoms, the binding of H atoms to these
surfaces does not alter greatly the spin density of the unpaired electron
in hydrogen. On the other hand, dependence of the width of the hydrogen
doublet components on the nature of the stabilizing surface indicates
that there is a definite interaction between the unpaired electron and
the surface. In view of this the authors suggest further studies of the
nature of binding of H atoms to solid surfaces. This is an abridged

Method of Paramagnetic Electron Resonance
PERIODICAL: Izvestiya Akademii nauk- SSSR. Seriya fizicheskaya, 1959,
Vol 23, Nr 10, pp 1263 - 1264 (USSR)
ABSTRACT; In earlier papers (Refs 1-3) it has already been shown that in
highly diluted dibenzene chrome solutions the interaction be-
tween the unpaired electron and the protons of the benzene
rings, which are in direGt, connection with the metal (chrome-)
atom, manifest themselves by a distinct hyperfine structure of
the spectrum of paramagnetic electron resonance. It has already
been shown that the introduction of a substituent into the
benzene ring influenees neither the g-factor of the compound
nor the amount of the hyperfine splitting (3-~�O.5 Gs). It was
further found that the dissolving temperature, the nature of
the solvent or that of the Bubstituent introduced into the

hyperfine splitting, as well as the width of the hyperfine
structure component. In this connection, several details, which
were obtained from references 1-8 are briefly discussed.
Further investigations concerning hyperfine splitting were
carried out with the cation of dibenzene chrome with cyclo-
hexyl substituents in both rings. It was found that at low
temperatures of the solution of 'his compound an additional
triplet splitting (1+0.5 Gs) of each hyperfine structure com-
ponent occurs* It is caused by the interaction of the unpaired
electron with two protons of a cyclohexyl substituent. kn in-
vestigation of the influence exerted by various factors on
the width of the hyperfine structure component gave the fol-
lowing result: A considerable dilution of the solution with a
reduction of temperature leads to a monotonic improvement of
the spectral resolving powert i.e. the width of the hyperfine
structure component decreases. In some solvents (e.g. alcohols)
an anomalous temperature dependence of the spectral resolving
power is found; this might be explained by a complex formation
between the dibenzene chrome cations and the molecules of the

The present paper intends to explain the nature of the inter-
mediate products inathe photochemical reactions of eosin and..
chlorophyll. The investigations.were ca rried out at room
temperature with high7frequency modulation of the magnetic
field. Method and apparatus are described in referenceis 1
and 2. First, some results concerning the photoreduction of
eosin are discussed. This reaction consists in the transforma-
tion of the dye into a leuco~compound.and has already been
potentiometrically and spectroscopically investigated 1,
(Refs 3,4). The authors 'assuined'that a comparatively.stable
intermediate.product is formea (semiquinone dye), ihich may
have a life of several seconds at room temperature. An investi-
gation of the paramagnetic electron res onance spectrum of
eosin (solvent: piridine, reducer: ascorbic acid) showed a

which is caused by the interaction between the unpaired elec-
tron and two protons. The photochemical reaction which-de-
velops by way of a biradical, is shown schematically and has
already been described by Schenck (Ref 5). The authors of the
present paper, were the first to investigate the resonance
spectrum of a live leaf. A leaf of agrophyrum repens was used
for this purpose. The resonance signal showed a doublet, hyper-
fine splitting amounted toAH = 1.8 + 0.2 Gs. There are 5 ref-
erences, 4 of which are Soviet.

ABSTRACT: In order to clarify the mechanism of the extension of the
component of superfine structure, the effect of temperature
on the spectrum of the electron-paramagnetic resonance of the

made with concentrated solutiona (more than 0.02 mol/1)
(solvents -- ethanol, pyridine, acetone) by means of a spectro-
meter with a high-frequency modulation of the magnetic field
(Ref 5)- It was observed that at the gradual lowering of
temperature, the width of the superfine structural component
(A H) of (I) and (Ii) is constantly reduced, and;reaches a
minimum at -509 -80 C. When the temperature is lowered beyond
thatg the width increases again. In all solutions of (I) and

came about by a superfine fission at the Cr53 isotope. It is
stated that there exists an anisotropy of the g-factor and
a superfine structure in the chromium--aromatio compounds.
Besides the temperature reduction, there are two more reasons
for the extension of the component of superfine structure:
One is due to the formation of stable complexes or solvate
shells, and the other one is in no connection with the exchange
interaction. In order to solve this problem it will be neces-
sary to carry out studies with diluted solutions in which
the latter effect is negligible. It is ascertained that a
temperature reduction may cause a better dissolution of the
superfine structure than a dilutiong and if this comes about
it can be observed with less sensitive instruments. Finallyp

TEXT: The authors proceed from the.photochemical reaction in the aque-
ous medium: M + H20 + hV --* x+ + OR- + 9 (1), where X may be metal ions
of variable valency, or anions. The formation of hydrogen atoms in this
reaction had been hitherto proved indirectly only. The authors wanted to
give direct evidence of H-atome by means of electric paramagnetic re-
sonance (epr). Because of the strong reactivity and mobility of the
H-atoms, investigations were conducted at 770K in aqueous solutions of
H2304 or H 3P0 4(in concentrations between 40 and 96%), which contained
small quantities of FeSO4 or KI. The samples were irradiated for 1 hour

with the ultraviolet light of a KPK-T (PRK-T) sorcury vapor lamp. The
*pr signals were recorded by means of a previously described (Ref. T)
syr spectrometer. ;-It was possible to give evidence of the H-doublet. To
check the correctness of reaction (1) definitely, experiments were made
in solutions which contairM heavy water. As in shown by Fig. 1, the
D-triplet was observed besides the H-doublet. Further experiments were
conducted in the system 006 - B20 - B280 4. Here as well (Fig. 2) the
9-doublet occurred. The central part of this spectrum, the quadruplet
shown in Fig. 3, could not be explained yetp but it might be due to a
param W otic,partiole whose free valency is localized on the aromatic
ring. Weaker components were detected in the epr spectrum of the
H-atom (Fig. 4), which are ascribed to the spin reversal of protons
surrounding the H-atom. While the H-lines were strongly saturated in
the experiments with benzene, saturation did not take place in the
presence of P02+ due to higher concentration of the paramagnetic ions
of a short relaxation time. The study of saturation and intensity
distribution between the main and secondary lines in the epr spectrum
of H' may serve to clarify specific features of its weak interaction
