TITLE: 9-egative Resistance of Glow Dischargel
PERIODICAL: deskoslovensky' &sopls Pro Fysil~u, 1959, Nr 4,
pp 377-383
ABSTRACT: An important characteristic of the glow discharge in
gases is the electrical d,c. resistance, A certain
range usually exists in which the potential drop In the
discharge is JndependeDt Of the current. This can be
explained by a simple theoiy (Ref 1). On the other hand,
the increase of the potential drop in a discharge during
the transformation to a dark discharge Is theoreti-,ally
not well understood. It has been found that the density
of electrons in the positive column decreases more
rapidly than the current, Allis and Rose (Ref 2) give
an explanation of this effect but do not go into many
details. Some further faetors that might explain the
negative resistance of the glow discharge have been
mentioned in Ref 1. The purpose of this present pape-r
is a.detalled j-nvestigation of this problem. It has
been experimentally found that the main change in
Card 1/4 resistivity during the transfoination from a glow discharge
to a. dark discharge, occurs In the pos1t1,,,e column (Ref A,.,

Negative Resistance of Glow Discharge CZECH/37-59-1f-6/1-6
We shall, therefore5 consider this region only. We shall
use the approximation (Ref 2) of assuming a constant
ratio between the densities of ions and electrons in the
plasma. The basic assumptions and formulae of this
approximation are recapitulated in detail. Most of the
equations used are taken from the theory of ambipolar
diffusion. Further relations are introduced In order to
establish the static character of the transformation
between free and ambipolar diffusion. The characteristic
is given by Eq (15), where
D_ = b_Ue , (16).
If the intensity of the electric field Ex for the
ambipolar diffusion is known, we can find the relation
between Ue and Ex from Ref 4. Ue is the temperature
of the electrons. As a consequence of step-wise
ionisation, the number of ions formed by each electron
per unit-time increases with the current. The ratio of
Card 2/)+ step-wise ionisation to the total ionisation varies from
gas to gas and is usually approximately proportionate to
the square of the current. We shall consider a steady V%

67019
Negative Resistance of Glow Discharge CZECH/37-59-4--6/i6
state of ambipolar diffusion where step-wise ionisation
is almost negligible.. Under these conditions, Eq (22)
will hold. Here, _* is the number of ions formed by
step-wise ionisation per unit-time, i.e. by collision
with an atom in an excited or metastable state.
According to our assumption, z, Is much larger than z*,
while Z* Is a function of the CUT-rent, and the other
components of Eq (22) are approximately proportional to
the field Rx. Eq (22). therefore, describes the
relation between the current and the intensity of the
field at the moment when stepwise ionisation sets in,
Eqs (24) - (26) desc,.rlbe the situation arising if the
current increases by AI. From all that has been said,
it can be seen that the step--wise ionisation can only
rarely affect the field intensity in the positive column
of a discharge. It cannot explain the negative gradient
Of the static characteristic of a glow discharge at small
current densities, because this is not compatible with
Card the dependence of the step-wise ionisation on the curT,:'4n4o'.
3/1+ The characteristic ourve can, therefore, be explained
only with the ai.d of the space-charge occurring during
the change ftom free to ambipolar, diffusion. I/

67019
Negative Resistance of Glow Discharge CZECH/37-59-4-6/16
The characteristic curve calculated from the simplified
theory of this change is in fairly good agreement with
experimental curves, but only over a very limited range
of currents. This discrepancy can only be explained by
considering further parameters. The ratio of densities
of positive and negative current carriers is not
independent of the distance from the axis of the
discharge, so that assumption 5 is not fully justified.
The diffusion coefficient Dk as calculated by Eq (6)9
is smaller than the real diffusion coefficient (Ref 2).

TITLE: De7:Fe~rmina-tio'n of the Moleculay Weight During the Emulsion
Copolymerisation of Butadiene'land Styren I- Loss of
Xanthogen Disulphides During Polymerisation
PERIODICAL: Chemick~ Pr-ftmysi, 1960, Vol 10, Nr 2, pp 103-108
ABSTRACT: The author investigated the effect of xanthogen
disulphides as regulators during the emul8ion copoly-
merisation of butadiene and styrene at 50 C when
potassium persulphate was used as initiator. The
composition of the purified, stabilised butadiene and
stabilised styrene, as well as of the other reagents,
is given. The degree of conversion was calculated and
the xanthogen disulphides analysed by using May and
Kolthoff's polarographic method of estimation (Ref 10).
Results obtained during the determination of the apparent
transfer constants and the rate of polymerisation are
compared in Table 1 and their dependence on the number
of carbon atoms in the alkyl group of the xanthogen
diBulphides shown in Figs 1 and 2. It can be seen that
the apparent transfer constant decreases logarithmically
Card 1/3 with lengths of the alkyl group; this phenomenon is

discussed in detail. Data on the solubility in water of
some xanthogen disulphides at 250C are given in Table 2,
and these values plotted against the number of carbon
atoms in the alkyl group of the regulator (Fig 3). Side
reactions of the xanthogen disulphides were also
investigated (Table 4) and it was proved that these
compounds do not react with any components of the
emulsion system under the given conditions of polymeri-
sation; the loss of regulators is only due to chain
transfer. Further experiments on the dependence of the
apparent transfer constants on the polymerisation
temperature showed that this is governed by the law of
Arrhenius. Calculated values for the activation energy
of the apparent transfer constants increase linearly
with the lengths of the al 1 group of the xanthogen
disulphides (Table 5, Pig 4~. The n-heptyl derivative
was the most satisfactory regulator. Equations are given
Card 2/3 expressing the dependence of the apparent transfer

constants on the number of carbon atoms in the alkyl
group for straight chain compounds and iso-derivatives.
All tested xanthogen disulphides inhibited the
polymerisation to a certain degree; this was most
noticeable in the case of the lowest members of this
series and it is'suggested that this is due to stabilisa-
tion of the xanthogen radicals. The xanthogen disulphides
do not enter into any side reactions under the given
conditions of polymerisation and it is, thereforel
possible to define the values of the apparent transfer
constants from their loss in relation to the degree of
conversion. There are 4 figures, 5 tables and 23
references, 3 of which are Soviet, 14 English, 1 German
and 5 Czech.

ABSTRACT: The stability of plasma in an oscillating discharge (14. V. Nezlin, ZETF 4,
15946, 36) has been investiga,ted. Within the framework of the linear theory, an
analysis is given of several types of instabilities in a mixture of hot electrons
and cold plasma, caused by the radie.3 inhomogeneity 6f the density of the hot elec-
trons. Instabilities of a similar type may exist even if the fast electrons move in
opposite directions so that the total electron current is zero. The author thanks

ABSTRACT: A diagram technique (developed by Konstantinov and Perel)l
of the temperature-dependent Green's function is used to study the
effect of neutral particles on the hLgh-frequency conductivity of
high-temperature plasma in the Born approxim&tion. It was assumed
that collisions between electrons and neutral particles in a plasma-;
neutral particle system are only elastic and that the frequency of
the electric field is much larger than the frequency of collision of:!
the electrons with neutral particles. Expressions for the real part!
of the electron-neutral particle interaction were derived for two

cases, 1) neutral particles and 'electrons are regarded as hard,
elastic spheres; 2) the neutral particles are hydrogen atoms in the
ground state. The ratio of this interaction in the second case to
that of the first case is approximately 10 to 105 for kT ranging
from 102 ev to 10 kev, trhere k is Boltzmann's constant and T is the

PERIODICAL: Chekhoslovitskiy fizicheskiy zhurna). v. 12, no. 6, 1962, 432-438
TEXT: Recent work on coherent radiation of relativistic electron clusters assumes that the clusters are
moving -,n a free space between two parallel conducting planes. The article discusses the case of electron
clusters in a closed cylindrical resonator with conducting walls and that all the electrons are moving in concen.
tric circles with velocity v - r. Maxwells' equations are solved and the magnitude and form of the tangential
component of the force acting on an isolated electron of a cluster of electrons is expressed. The graphs show
that in the case of non-resonance the electrons in the front-part of the cluster are braked, whilst electrons in
the back part of the cluster are accelerated. In the case of resonance the electrons in the center of the cluster
are maximally braked, The results arc useful for investigating the dynamics of electrons in a synchrotron

ABSTRACT: An analysis is presented of the nonlinear effects caused by plasnia
instability in an oscillating discharge. An estimate is made of tile energy of
unstable oscillations and of the coefficient of turbulent diffusion of plasma using
equations of the theory of weak turbulence. The author thanks V. Kopecky and
i J. Preinhaelter for their valuable discussions of the problem. Orig. art. has:

TMCT: This article is a continuation of the study entitled "Girders with
thin websr' that was published in this periodical, no. 1, 1962, P--~5. There the
Wagner theory of girders with thin webs that corrugate when loaded was described.
---From-this--theory-a--practiec-illy-apglicable-engineering-theory-vas--derived--to -_ solve
problems dealing with shear-stiff webs and the limiting cases of thin webs. The
present article should facilitate computations of aircraft static analysis by
giving a method that is practically applicable. An equation for the critical
shear stress of the web is given. Nominal shear stress in the flanges, diagonal
stress coefficient., "L" anew 11H" shaped beams., and maximum shear stress in the web
are discussed. A method for check calculations of bolts is given. Orig. art. has

TITLS: A method of protecting the surfaces of molten iron alloys against
oxidation
PERVbDICAL: Referativnyy zhurnal, Metallurgiya, no. 11, 1962, 120, abstract
111787 P (Czechosl. Patent no. 99138 of March 15, 1961)
TOCT: The method of protecting molten Fe-alloy surfaces against oxidation
consists in that low-melting B and (or) P compounds are introduced into the melt,
and form on its surface a protective cover In which air-02 is dissolved. Chef..i-
cally neutral, low-melting substances, such as NaCl or CaC12, may be added to the
compounds to be introduced In amounts assuring a _,~ 4% content of B or P compounds
in the mixture. An approximate composition of the mixture is (in %) B203 20,
NaCl or CaCl 80.

Title Synthesis of 3,5-Diethylpyridine.
Orig Pub: Chem. listY, 1957, 51, No 8, 1510-1516.
Abstract: To study the formation of quaternary pyridinium
salts, the hitherto not described 3,5-diethylpyri-
dine (I) was synthesized. The ethyl ester of di-
nicotinic acid (3,5-dicarbethoxypyridine) (II)
forms (contrary to expectation) on Claisen's con-
densaticn with ethyl acetate only a single reaction
pro-duct -- the ethyl ester of 5-carbethoxy-nico-
tinoylacetic acid (III). The latter was converted
by ketonic cleavage and reduction according to

Kizhner-Wolf to the ethyl ester of 5-ethyl-nico-
tinic acid (IV). The bifunctional reaction product
could not be isolated but its occurrence was de-
monstrated by isolation, after the cleavage of the
crude product, of a svnU amount of 3,5-diacetylpy-
ridine (V). The required I was obtained with a
good yield from IV by carrying out the above-des-
cribed reactions. A solution of II ine thyl acetate
is shaken for 1 hour with a suspension of C,1~-ONa
