ABSTRACTt
The input capacities of visual, auditory, and tactile *.analyzers were
.investigated in 24 crew members during nine long flights. Tests were
conducted on a special apparatus which supplied light, sound and
tactile stimuli in random order, to which the subject responded by
pressing the appropriate button as quickly as possible. The following.

Information processed, Input (or traffic) capacity,. and lime required
'for processing one unit of information. It was found that the input
capacity of the visual analyzer increased gradually in the first 9 hrs of
flight, and then decreased by the 15th hr. ilowever, the input capacity t
of the auditory analyzer decreased regularly during th6 entire flight.
The input capacity of the tactile analyzer increased (with some varia-
tions) until the 12th hr,. and then decreased to initial ldvels....
The gradual increase in input capacities observed in visual and
'tactile analyzers in the first 9-12 hra of flight is probably due to
.pdaptation of the organism to new conditions, With increased analyzer
lability. The subsequ3nt decrease in input capacity is caused by
-fatigue, first noticed in crew commanders. The high noise level in
the aircraft contributed strongly to the decrease in auditory analyzer
input capacity. Characteristically, the greatest shifts in auditory
function were observed in commanders and radio operators, who are
responsible for external and internal radiocommunications. The
visual analyzer is kept in a continual state of stress by the necessity*
for constant monitoring of many instruments. In the auditory

ABSTRACT: The recombination radiation spectrum of CdTe excited by
fast electrons was investigated in th photon energy interval from
0.7 to 1.6 ev and at temperatures betteen 10 and 300K. The p-type
samples with resistivity of lu 10 ohm-cm were excited by 1 Hev elec-
tron pulses of 2.5 jisec duration from an electrostatic generator.
The repetition flreaquency was 10 cps, and -the current density per
electron pulse varied betweeen 0.3 and 0.5 mA/cm. Since a 30 hr
exposure to this type of ir-radiatLon did not affect the recombination-'--

radiation spectrum, it.was assumed that the effect of the formation
of radiation defects could be neglectedo It was found that at 10K
the recombination radiation spectrum consists of three intense bands:
*~U_ith maxima at photon energies of 1.05 + Olp 1.47 + 0.01, and
1,59 + 0.01 ev. The short-wave emissiZ band is l;cated in the
region of the fundamental absorption band, Analysis of the dats,
shows that vertical transitions with emission of optical phonons
with zero momentum occur in CdTe and that the probability of such
processes is high,' According to criteria developed in: Basov,.

ABSTRACT: The purpose of the investigation was to determine by mans
of a new procedure the Ionization energy under conditions whete the
excitation is not confined to the surface region. It is shown briefly
that the latter circumstance resul-ts in certain errors. The I.oniza-
tion. energy was determined from the change in the voltage drop, and
consequently from the change in conductivity, resulting from irradi-
,-_Iating a crystal with electrons from a 150-keV accelerator. IF mula

relating the voltage drop with the Ionization energy is writtei under
the assumption that the concentration of the nonequilibrium ca--;.,riers
varies linearly with the time after turning on the excitation, and
that the current density of the incident electrons is sufficiently
small and uniform over the entire surface of the sample. The iieasure-
ments were made on n-type Ge~and a-SiC measuring 4 x 6 x 1 and 2 x 4
x 5 mm res eatively, The ionization energies were found to be 9:0 +
0.7 and 2N + 0.2 ev for the silicoq carbide and germanium resl:ective-
ly. In the jase of silicon carbid6'--, the results agree with the as-
that the Jonizatlon ~_nerg~ is approximately itriple tht!

agree with data obtained by x-ray and gamma-ray excitation,' but are

ABSTRACT: Connected with the outfits described by C. Benoit at al. (Physics of
Semiconductors, Paris, Danod, 1964),an improved outfit developed by the authors is
capable of exciting semiconductors by 150-kev electron pulses that have a current
density of 3 amp/cm2; pulse duration, 0.25--10 (,%seal repetition rate, up to 30 cps.
Stimulated radiation of cadmium telluride was achieved in this outfit for the first
time. An electron tube with a constant high voltage and a pulsed grid modulation is
used for high-power electron excitation of semiconductors; a 20-section steatite
tube has been actually used. A block diagram of the outfit, principal circuits
of the pulse generator and synchronous detector, and the pulse shape of the electron
beam are shown. A He cryostat permits studying the recombination radiation of
semiconductors at temperatures down to 10K. "The authors wish to thank-S. I.

TITLEt On Metric Dimension of Point Sets
PERIODICAL- Matematicheskiy sbornik, 1959,V01 48,Nr 2,pp 227-2150 (US-N
3H)
ABSTRACT: The present paper is devoted to the investigation of the notion
of the metric dimension of the given point set M (in sye.bols
dm M). dm M is the smallest number r with the property that
there exists an arbitrarily small shift of the set M int) a
locally finite polyhedron with the dimension r. Principe.!
results:
Theorem% Let R be a metric spacei we have dm Rj;~r thnn,cnd only
then.,,if in every Lebesgue covering of R an open cove=inj: can be
inscribed the multiplioity of which is _4,r+1.
Theorem: Let MCE. Then dm M is the greatest number x w.1th the
property that there exists a uniformly continuous, easeiitial
mapping of M into an r-dimensional closed simplex.
Theorem; If dm R - r and AC-R is an arbitrary set, then every
uniform 7-cycle of A, the dimension of which in ptr, c~Ln be
continued to the whole space R (a uniform V-cyclo of a set is
every VF-cycle defined on the nerve of a Lebosgue coverl.ng of

ABSTRACT: A study was made of the intensification of q zinc-plating
process by means of ultrasonic oscillations in an 800 X plating tank.
A diagram is given of the distribution on Ito bottom of submerged
magnetostriction transformers and of the values of sonic pressure on
the liquid alonZ the entire mirror of the tank, The irregularities of
the plating and the given irregularities of sonic pressure did not
exceed 151%. The zinc-plating was done us:L,,3 an electrolyte of the
following composition: (in h/1) ZnO 10-li~; 1411401 21j0-260; joiners'

results were obtained In Zn deposits in the 800,Qtank unjr-r the con-
dition developed for zinc-plating In tanks of 20 and 80 capacit7.
An 5'nereased electrolyte concen ration and a change of P11 to 7.2-3.5,
allowed Increasing ]?k to 5 a/dm . Under these conditions good-quality
deposits were obtained,, but the anodes were pasaivated. In order to
minimize the paosivation, tho anode surface was enlarged, It was noted
that in plating metals using ultrasound, the mounting of parts and
their orientation in relation to the radiating surface of transformer
and anodes are of great importance. Tests under industrial conditions,
of this electrolyte with applied ultrasound shoi,ed that the work of
this electrolyte was stea0y and that the productivity increased by 5
times. N. Balasheva

the true tensile strength SX, U.T.S. (a ), and the reduction of area,

changes in the mechanical properties of the investigated material

several specimens were held at 7200C for periods equal to thot-,e

temperature variation, stayed at this temperature, after whic*A-1 their
mechanical properties were also 4etermined. Finally, the effect of
the cyclic temperature variation on the notch sensitivity of t;he
investigated steel was studied on specimens in which holes 1.?'

diameter had been drilled prior to the experiments. Several
conclusions were reached. (1)'Cyclic temperature variation lowers
the strength and ductility of both annealed and work-hardened
austenitic steel to the extent which depends on the upper temperature
limit of ttLe heating/cooling cycles and the number of cycles, (2) The
observed reduction in strength and ductility is due to the action of

stresses set up in the material during cyclic heating and coolLng.
Prolonged heating at temperatures employed in the course of tha
present investigation has no harmful effect on the properties of
the steel studied. (b Preliminary plastic deformation has no
significant effect on the sensitivity of steel lKhl8N9T to cyclic
temperature variation when the number of the heating/cooling cycles
is relatively small. However, when a certain critical number of
cycles, which depends on the upper temperature limit, is exceeded,
strength and ductility of work-hardened steel decrease more rapidly
than those of the annealed material. (4) The harmful effect of
preliminary plastic deformation is apparently not removed by the
processes of recovery and recrystallization which must take p'Aace
when the specimens are heated. (5) The presence of stress risers
in the specimens of steel lKhl8N9T, subjected to cyclic tempeiature
variation between 800 and 200C, results in a sharp decrease ii. their

TFAT; Qiving several examples, the state of stress in workpieces subject'id to
oyclio temperature variations is discussed. It i a pointed out that all st!~tes
of stress and deformation (monoaxialt biaxial, tri&Xial) can occur under ';he
influence of temperatures realized'under practical conditions, It would
therefore be necessary to lay down the technical theory of strongthp sinc4 the
behavior of material in an arbitrary state of stress can, according to th)
well known criterion of strength, be determined from the test results of A
aimple state of stress. First.-experiments in this direction were made by
V.No Kuznetsov (Ref. 2) and L. Coffin (Ref,. 3). Kuzneteov regarded the d4.:.
formation energy as criterion of,strength. As the results obtained by theitwo
investigators are in good agreem~ntq It may be assumed that the deformati!)n
t4nergy can be regarded as criterion of strength. In the present publioati.162 a

method for testing thermal fatigue under pulsating torsion is described, in which
an alternating state of pure shearing stress occurs. The fact that the extreme
deformation values correspond to the extreme values of test temperatures 11aa
taken into account when working out the test methodp and a corresponding leating
apparatus (Fig. 3, scheme) was designed, The amplitude of the torsion ang:16
of the sample can be varied within a wide range. Specimen heating is offected by
passing a current through, while the coolant flows through the specimen via an
electromagnetic EMK valve, An EPV-Ollqpotentiometer is used to control the
heating-cooling cycle. Tests were carried out using special thin-walled tube
specimens (Fig. 5) made of.refractory alloys. Temperature cycles of 6300--:700
and various mechanical deformation amplitudes were applied. From test results
bbtained, the fatigue curves were plotted in the semilogarithmic coordinates

TEXT-. Failures caused by thermal fatigue are of great importance in the construction of airplanes, rockets
and thermonuclear installations. Thin-wallcd tubes of 314-888 (E1-888) austenitic and W-852 (ET-852) steth
were investigated for a temperature range from 650* to 250'C. The samples were heated by an electric current
and cooled by a stream of air. The duration of one cycle was 30 sec. Heating by an electric current incrcaies
the sensitivity of the test because it causes overheating of the defective spots and therefore the failure of Cie
sample takes place soon after the first crack occurs. In the discussion, Nikitina L. P. expressed the opinion
that the heating-cooling cycles were too short, and that it may be necessary to keep the materials for a more
prolonged time at the elevated temperatures for a truer evaluation of the thermal fatigue resistance, K I
Kononchuk pointed out that it is not exactly clear what the authors mean by a failure, whether it is C'ic
oCcurence of a crack or a breaking-up of the sample. Fle also sees no way of using the rcsults of this inv-s-
figation so as to include an evaluation of the strength of materials under different combinations of stresses

TEXTi Testing methods were developed withallowance for the conditf
:on
that the rates of mechanical deformation may be both smaller and grkiater
than those of thermal deformation. Firstp if the mechanical deform-.tion
is equal to or smaller than the thermal deformation# a testing mach!.ne is
used which is similar to that employed in tebte with variable load
rigidity (S. V. Serensen and P. I. Kotov. ~avodskaya laboratoriya, XXV,
10 (1959))- "Softer" load conditions with the mechanical deformat -:ou less
than the thermal deformation are obtained by a free play between Vle sample
and the clamping bolt or by using elastic elements (calibrated Bel!.eville
springs). Although the kind of deformation is different owing to the two
types-of load involved it does not affect the endurance of the sariple
before cracking. Evaluation of the total endurance indicates tha-41 load

rigidity is easier to vary with the free play. Similar conditions were
observed for meohanical fatigue (R. Do Vagapov and Ta. B. Fridman.
Zavodskaya laboratoriyal XXVII, 2t 183 (1961)). Secondly, if the
mechanical deformation is stronger than the thermal deformation, fatigue
is tested with a tensile-and-compression-testing machine. The sampl-:-s are
subjected to an additional pressure while being heated and to additional
elongation while being cooled. Thermal and mechanical cycles were
programmed only for the basic conditions of thermal fatigues that oxtreme
values of 'deformation correspond to extreme temperatures. Under ac'~ual
condition for the great variety of temperature and deformation variations
per cycle, a special follow-up system has to be used in programming. The
methods proposed here were used to set up fatigue curves for a wide range
of stress-strain variations (200 - 10,000 cycles) under equal thermal.
conditions (650.=~25000 for the steel grades 90852 (EI852) and _N888
(EI888). The results were comparable to those obtained by determining the
fatigue of a material at a constant temperature or in other states of
stress within the same temperature range (Ya. B, Fridmant 9. Do Sobolev and
