TITLE: On the Stability of Periodic Methods of Oi;eration in Non-
linear Systems With Piece-Wise Linear Charocteristics (0b

ABSTRACT: A method is described here by means of which the equations
of a linear approximation for solving problems concerning
the stability of a periodic solution in a system with piece-
wise linear characteristics can be found. As in references
I and 2 the automatic control system is here expressed by equa-
tion (1). At first the more general equation (2) is investi-
gated and beside it also the linear equations (3) which,
supplemented by linear relations, yields equation (4). Formulae
(3) and (t~) toj;ether determine the discontirmuri into~;ral curves.
The totality of (3) arid (4) is deaienated an linear approxi-
mation of (2 )for the periodic solution of (2)zi - z i(t). (f(zj)
Card 1/2 is given function which is piecewise linear). By additional
On the Stability of Periodic Methods of Operation 103-19-6-9113
in Nonlinear Systems With Piece-Wise Linear Characteristics
limitations the following theorem is obtained:(reference 1).
When the zero-solution x i - 0 of a system of linear approxi-
mation (3) + (4) is asymptotically stable, the periodic so-
lution z T.(t) of the set of equations (2) also is asympto-
tically stable. Going back to the set of equation (1) the
equations (31) and (4') are obtained for it. Linear relations
are found and written down in matrix form: x(t 0+,r). ux(t 0)3P
where U denotes the constant transformation matrix. For the
stability of the periodic solution of syster, (1) it is
sufficient when the roots of the characteristic equation
det(U-X E)-O lie on the circle of unit radiua. The problem
concerning the stability of the periodio solution of system
(1) can also be solved by direct alignment. There are 4 refer-
encesp 4 of which are Soviet.

shown that, if f4 (0) and f- (0) are not collinear vectors, the P'Osi-

TITLEt Anisotropy of Surface TensionAat the Interface Between the

PERIODICAL: Zhurnal eksperimen,,allnoy i teoreticheskoy fizikl., 1960,
Vol. 38, No. 5, PP- 1456-1470
TEXT: The present paper is a detailed report on the determination of the
anisotropy ib of surface tension at the interface between the super-
conducting (s) and the normal (n) phases of tin, using two methods that
give directly independent values for A. 6 has the dimension of a length,
and is related to the free surface energy 6' no by the relation
d, 'AH2 /8tr. The difficulties in the experimental determination ofj~
ns 0
are discussed in the introduction. Then, the first method is described.
It is based on an analysis of the structure of the intermediate state on
samples with different brystalline orientations, the analysis being made
with the help of ferromagnetic powder. The apparatus used is schematically

shown in Fig. 1. The results of the method, called "the method of frozen
flux" and described in detail, are separately discussed for the individual
samples. Figs- 4-7 reproduce photographs of the structures of the inter-
mediate stage in a field of view 1.4 cm in diameter; the white regions
are superconducting, the arrows show the projection of the crystallo-
graphic axis onto the surface of the sample. The numbers of the samples
and the temperatures are also given. Figs. 8-10 and '13-15 give the cor-
responding polar diagrams. The second method is based on the measurement
of the moments of force acting on spherical samples in a magnetic field.
This method is called the "method of torsion balance", and is also
described in detail. Due to the anisotropy, the free energy of the sample
depends on the orientation of the magnetic field relative to the crystal-
lographic axes of the sample. The sample is suspended by an elastic thread
in such a way that in the state of equilibrium the moment tit - -aF/11111L may
be determined from the angle of rotationo4 in a horizontal magnetic field;
A is calculated from M. Densities, impurity concentrations, and the
momentYA of nine samples are given in Table 1.. Figs,. 18-21 show the angular
dependence of the moments m (m - 8,TM,/H2V, V - sample volume) for different

various positions (f is the free energy divided by VH2/81r),j ml and

surface tension on the direction of the normal to the interface, the
order of absolute magnitude of this affect, and its temperature dependence
are discussed in detail. Finallyq VAI
the results of the two methods are
compared with each other as well as with the results of the theory.

no investigations have been made so far for ranges where the theories of
Ginzburg and Landau do not apply. To clarify several discrepancies, the
authors studied many specimens, employing.*,jke more accurate radar-
frequency method. A. A. Abrikosov, L. P.GcllWov, and I, M. Khalatnikov
(Ref. 12) developed a method for a theorJiTal estimation at limited
frequencies. On the basis of the experimental data, the authors selected
an operating frequency of 2 megacycles. The following part of this paper
deals with the measuring methods, the measuring instruments and their
calibration, the necessary control tests, and the evaluation of the
results. Superconductivity vanishes at the sharp bend of the curve

TZ',,"'T: A constant magnetic field causes t'he electrons on a spiral path
to penetrate into the metal beyond the skin depth. If the size of the
soeci.men is equal to the diameter of the electron orbit, this will cause
scat'-erin '- of the electrons from the crystal boundaries. The diameter
depends on the field strength. This kind of effect becomes evident in
the behavior of the impedance. Experiments were made with single-crystal
tin plates with an electron free path of 1- 3-10- 1 om at helium
temperatures. The variation in frequency (,./10 6 cps) with variation in
ma6netic field strength owing to the specimen-induced variation in the
reactance of the oscillatory circuit was measured by a modulation
method. 5.7-10

Anew type of size effect was observed when measuring the field
dependence of the surface i-;pedance of tin at helium~temparaturen, using .7
frequencies of 1-5 i4c. The measurements were made with a highly pure V
single crystal (,-10-4tA impurities) cut as a plate perpendicular to the
10dI a~:is, thickness d - 0.39 mm; the electron mean free path was
(1-3)-10-lcm, the skin depth at 1-5 Mc was 10-4 cm. At a field 11 0 - 2cp/ed

perpendicular to the -2 direction and normal to the surface) the curve X(H)

ABSTRACT: Continuing an earlier investigation (ZhETF, v. 44, 811,
1963), the dimensional effect is used to study the extremal electron-
ic orbits of a tin specimen in the (001) plane, with the magnetic
field lying in the (001) plane. The installation used was the same
as in the earlier investigation. The results show the following to,
exist in tin: an open surface very similar to the almost free elec-
..tron model, a closed surface*whose dimensions provide a basis for
assuming it to correspond to the surface of zone Q of the model, a
surface corresponding to the closed surface'obtained in the.earlier

has not yet been ascertained. It is pointed out that the data
admit of ambiguous interpretations and that information on the-ex-
tremal orbits of the three principal crystallographic planes is in-
addquate for the complete determination of all the Fermi surfaces.

ABSTRACT: The Fermi surface in In Is investigated by the radio-frequency size effect
technique at a frequency of 3 Mc/s. Identification of th6experimental cr~oqs sec-
tions was made using the dependence of the size effect lines on'the inclination of
the magnetic field relative to the sample's surface. The compllix~shape of! the Isoen-
ergetic surface in the second band resulted in the appearance at a number at sike
effect lines due to the presence of breaks in the electron trajdciories in 4 magnetic
field. These lines are not related to the electromagnetic field bursts within the
metal but to less notable features of the field distribution between the Vursta4 The
set of linen associated with the Fermi surface of thelsecond band confirms the fact
that this gurface is very similar to that predicted by the almost free electron model.

No lines have been observed which would indicate that the Fermi~surface may'be open.
It also follows from the experimental data that the Fermi 4urface in the third ienergy
band consists of tubes connected into rings, the axes of*ilie tubet; being oriented

section with a plane perpendicular to the tube axis was de termined by USiUg!Beveral

ABSTRACT: The authors report here the results of preliminary experiments in which
they observed excitation of sound in Bi by an electromagnetic wave incident on its
surf-ace. Single-crystal BI samples in the form of discs mere placed inside an in-
ductance coil, with which they were cooled to helium temperatures. The coil together
with the sample served as the inductance of the tank circuit of an rf oscillator,
which included a blocked semiconductor diode. The dependence of the barrier capaci-
tance of its p-n junction on the blocking voltage made it possible tovary smoothly
the oscillation frequency, and also to modulate it sinusoidall~y at a frequency (P - 19
cps. The oscillator output was detected and fed to a narrow-band amplifier with syn-
chrcnous detector, tuned to double the moduletion frequency 2cp. As a rtsult, the
2p/af2

ance). 71he dependence of Z'Wa& on f uas investigated in the interval 1 - 10 Yjiz.
In magnetic fields on the Cirder of 10 - 100 Oe and parallel to the coil axis, a group
of equidistant peaks appeared on the a2)Vaf2 curves, separated by frequency intervals
larger by one order of magrLitude than the width of each individual group. The mag-
nitude and direction of thc! magnetic field affected only the amplitudes of the peaks,
tl.e positions of which reme.ined; unchanged. Arguments are presented to show that the
observed excitation of sound in Bi is due to some specific mechanism, connected with
emission of sound as a resUt of large electron drift velocity. It is concluded,
however, that further experiments are needed to clarify the sound-excitation mecha-
nism. The authors thank Academician P. L. Kapitsa for the opportunity to perform
the experiments at the Institute of Mysics Problems, and Yu. V. Sharvin for interest
in-the work. Orig. art. has: 2 figurea.

The following problem is considereds two real polynomials D1(p) and D2(p)
are given. The number of their zeros in each of the four quadrants, on the
positive and on the negative semiaxia and in the origin of the coordinated*
is known. It is asked for necessary and sufficient conditions for this
distribution of zeros such that the polynomial D,(p) + D2(p) satisfies the
Hurivitz conditions of stability.
Necessary and sufficient conditions are given for a series of special canes.
For the general case there are presented only four necessary (but not
sufficient) conditions.

ABSTRACT: The three-membered evaporation apparatus of the system GNIIKhM
is the one most often used in the Soviet factories. Since this
apparatus has some deficiencies, and the production of
caustics has increased, a new apparatus was constructed in one
of the chemical plants which has a much greater output and
better economic properties. Besides the author of this article

pated in this construction. The paper gives a diagram of this
new evaporation apparatus, and from its description it may be seen
that in the second stage new apparatus with forced circulation
of the solution (after the construction by the NIIkhimmash)
were employed. Some changes in the dimensions were made. The

stage by a proper use of the function of the heat transfer
coefficient vs. the temperature difference, while in the second
stage it increased 3-4-fold by the above mentioned change. For
separating the salt from the liquid mustic potash automatic
horizontal centrifuges of the type AGwere used. These centri-

fuges were manufactured by the Suuy Factory imeni TJ.V.Frunze
(Sumskiy zavod im.I.I.V.Prunze). The --heme elaborated for the
plant is automatic in almost all operations, and the author

ABSTRACT: The author states that as a result of work
carried out by the Vsesoyuznyy nauchno-
issledovatellskiy institut istochnikov toka.
(All-Union Scientific Research Institute for
Sources of Current), a ferrocarbon element
has been produced having an alkaline electro-
lyte and electrodes made of activated carbon
and porous iron which serve a similar pur-
pose to cupric oxide elements (MOE) and ele-
ments with manganese-air depolarization (MVD),
but which do not use non-ferrous metals and
other scarce materials. They cLn be used for
the filament power supply of the "Rodina",

railroad si7,nalling and automatic block sys-
tems,telephone lines, lighting etc. The
electrical power is produced by the reaction
of active porous iron oxidation by the oxygen
in the air. The negative electrode of the
element is the porous iron (porosity of ?5-..
80%), the positive one is the air polariza-
tion carbon electrode. The composition of
this electrode is fully described. The ele-
ment is contained in a steel cylindrical con-
tainer: its inner construction, main feature
of which is the horizontal positioning of the
electrodes, is described and illustrated in
Figure 1. The horizontal positioning of the
electrodes improves the working conditions of
the carbon electrode, makes it possible to
use pieces of porous iron which have not been
specially processed mechanically, and simpli-
fies the design. An element ready for work
Card 2/4 is shown in Figure 2a and two elements mounted
VDZh--400 Perrocarbon Elements
SOV/107-58-12-42/55
on top of each other in Figure 2b. The
basic features of the element are as follows;
diameter 221 mm, height 75 min, weight 5 kgj
emf 0.9-1.0 v. normal discharge current 0.5
amps, maximum permissible current 0.8-1.0
amp, capacity with a continuous discharge in-
to a resistance of 1.25 ohms u-P to a voltage
of 0.5 V is not less than 500 amp-hrs, capa-
city with discharges of a lengthy, inter-
rupted nature is about 400 amp-hrs. The dis-
charge curves of the element when it is under
continuous discharge against resistances of
1.25 and 0.8 ohms are shown in Figure 3a and
comparative discharge curves of the element
with that of the MOE-500 cupric oxide element
(curve 2) in Figure 3b. The basic character-
istics of the VDZh-400 end RME-500 elements
and the IvTVD "Ek-ran" and "Deviz" batteries are

VDZh-400 Ferrocarbon Elements
SOV/107-58-12-42/55
the author are that the VDZh-400 element
has the following advantages; it does not
use up scarce non-ferrous metals, has a
simple desi-n and is very suitable for mass
U
production. There are 1 schematic diagram,
2 drawings, 2 gra-Dhs and 1 table.
