The authors mention Abrikooov who studied the superconductivity of metals
with high electron gas density, and R. N. Bogolyubov et al. viho made
calculations for metals (Novyy metod v teorii sverkhprovdlimosti, izd.
AN SSSR, 1958). The authors first consider a model with isotropic
effective mass. They derive an equation for calculating tile energy gap

These formulas obtained for the model with isotropic effective mass
also hold for the anisotropic case up to and including one numerical
factor under the natural logarithm. In piezoelectric semiconductors
the attractive force between the electrons contributes to the exchange
of piezoacoustic phonons. Superconductivity can be the most favorably
studied in those polar semiconductors in which the electrons in the
conduction band are sufficiently concentrated and in which they are
strongly coupled with the lattice vibrations. There are 1 figure and 4

TITLE. Collective excitations of particles with non-zero angular

TEYT: in this contribution to the theory of superconductivity, systems are
examined in wihich the at-tr--ction in a state with 10 -1 0 is dominant, as in
r
the case of HO where the attraction in the D state is dominant (L. P.
Pitayevskiy, ZhETF, 37, 1794, 1959). As well as those from single
Particles, collective excitations in such systems are examined. The shape
of the excitation spectrum is important for explaining of superfluidity
properties as well as for stability investigations. The equation for the
Cap -A in the energy-specil-run admits of general solutions only in the case
of zero angular momentum pairing (two solutions; 0, and 0).
,here non-zero moments are paired, special solutions must be sought.
Collective excitations are examined here by a relativity technique as

TEXT: Experimental data on the cross sections of the reactions
+ p ~t + K and n- + p--+-A-+ K near the Z + K threshold are
phenomenologically analyzed. A level in the system Z + K with T 1/2
with a binding energy of about 30 Mev is assumed to exist. In the cross
section-of the reaction n + + K; this level leads to a resonance
below the 7- + K threshold. Possible levels in the systems A- + K, N + Q,
N + ca, and N + Kk are discussed. To clarify the interaction between "~'and
X in states with T - 1/2, the cross sections of the reactioh n + N---gJL + K
must be studied in the energy range T. - 810 - 900 Mev, and of the reac-
tion A- + p---~'Z + K, near the threshold. The analysis is conducted by

TEXT: Fermi and Yang (Phys. Rev. 79, 17399 1949) ivere the first to develop
a model in which a meson is considered a bound state of baryon and anti-
baryon. This model is now modified. The nucleon-antinucleon bound states
are considered for the case where the interaction can be described by a
potential well, but instead of the Breit equation (solved by Fermi-Yang)
the Bethe-Salpeter equation is solved. The.difference is that here the
Dirac vacuum is partly taken into account becauser, for the nucleon
considered, a transition to-a negative-enerFy state is forbidden. Inter-
actio with the vacuum leading to NN-interaction and changes in the nucleon
mass neglected. Thus the interaction is described by

of Fermi-Yang, such as a larger well depth or large number of levels are no
-longer valid. From Eq. 09) it follows that at strong interactions the
square of the pion mass becomes negative which indicates vacuum instability.
This can be avoided if the change in nucleon mass (due to interaction)
is taken into account.

ABSTRACT: The author proves that the Knight shift in some superconductors cannot be
attributid to electron pairing in a state with unity orbital angular momentum, as was
proposed recently by several authors (e.g., R. Balian and N. R Werthamer, Phys. Rev.
Y- 131P 1553., 1963)p because the.theoretical analysis of the v;ctor pairing was made
for infinite space$ whereas the experiments were performed on samples with dimensions
tuch smaller than the depth of penetration of the magnetic field. By analyzing the
Influence.of impurities on vector pairing, it is shown that vector pairing vanishes
when the pair dimensions are larger than the sample dimensions or the electron mean
free path, whereas in ordinary scalar pairing the transition temperature is indepen-
dent of both the sample dimensions and the impurity concentration. The reason for
this.:difference is that in vector pairing the wave function F of the pair depends on
the direction of the relative momentum of the electrons forming the pair,, and -vanishes

Sample being-of the order of the pair dimension. Although the article deals only with
one form,of a state with vector pairing, the equation derived for the critical temper-
ature is valid also for other cases. When the normal state is checked for stability,
the critical temperature determines the point at which the electron scattering ampli-
tude-has a pole at zero frequency. Further decrease of the temperature leads to the
occurrence of growing excitations in the normal states. Consequently the experiments
on the Knight shift (G. M. Androes and W. D. Knight, Phys._Rev. v. 121, 779, 1961) can
not be attributed to the existence of vector pairing. So far., the only natural ex-
planation for these experiments is spin-orbit interaction with the impurities. Author

ABSTRACT:* The purpose of the investi6ation was to determine the region of applicabil-i
ity of the Landau phenomenological theory for phase transitions, inasmuch as this t1
ory disagreeswith experiment in the direct vicinity of the phase transition point.
Since the phenomenological theory is equivalent to the zeroth approximation of the
self consistent field method from the microscopic Point Of view, the allthorS consider
the phase transitions in an Isinge model and in crystals for a large interaction radius"
ro. Then the method of constructing the successive approximations is illustrated vitl~ !
, model as an example. The first two terms of the expansion in terms of the
the Ising A i
parameter r63 are obtained in the correlation function and in the thermodynamic quan-
41.-ities. The methods developed for the Ising model axe then applied to the more cor,,
plicated case of phase transitions accompanied by a change in crystal symmetry. Tae.
influence of the electric dipole-dipole interaction in ferroelectrics is analyzed and i

everywhere except a narrow region near the transition point. Me phenomenological
the,ory is best applicable to superconductors, where the role of the interaction radius;

ABSTRACT: The authors derive a general expression for the Josephson tunnel current
between two superconductors separated by a dielectric barrier for an arbitrary volt-
age applied to the barrier and for all temperatures. The limiting cases oll' slow and
fast time variations of the voltage are considered, and also the case of small volt-
ages with arbitrary time dependence. The expression for the current is reduced in
all these cases to four single integrals, for which the limiting values are obtained.
These limiting cases are superconductors without magnetic impurities and supercon-
ductors with paramagnetic impurities. The authors thank 1. 0. Kulik, A. V. Svi-

ABSTRACT: The authors present a microscopic treatment of critical excitations in
solids with temper4ture-dependent frequency, which tends to zero on approaching the I
transition point, The theory developed makes it possible to explain the region of
existence of the critical vibrations and the physical meaning of the phenomenolo6ical
parameters employed. Simple models, which are not related to any specific sifostarce
but which include all the essential properties of the real crystals, are considered.
7ne interaction radius is assum d to be large enough to permit the use of the self
consistent field method. This method is then used to determine the spectrum of these
excitations and the dispersion of the dielectric permitivity in ferroelectric transi-
tions. A diagram technique, which makes it possible to calculate further approxima-

tions of the self 'Consistent field method, is developed. The dam-Ding of the exci,~a-
tions is determine& with the aid of this method. it is found that very close -ro ha
critical frequency,the damping is comparable to the frequency~ so that the concept of
vibrations loses its meaning. The critical vibrations are thus described in the en-
vire region of tiieir existence in the self-consistent field approximation. The appli-I
cability.of the results to real systems is discussed, and an extension to first-order
transitions is considered. Orig. art-has: 3 figures and 55 formulas.

ABSTRACT: As early as 1947, Ye.A. Chudakov, and in 1950 and 1953 V.A.
Dobrovol'skiy and N.S. Acherkan pointed out that splined
shafts should be calculated by the inner diameter of the
grooves. The stability of such a shaft then equals that of
an even shaft the diameter of which is somee.,hat less than
the inner diameter of its splined end. But automobile de-
signers have not yet heeded this suggestion. The present
calculation method of axle shafts of ZIL-150 (Photo 1), the
3-axle ZIL-151 and the ZIL-585 dump truck is described and
test results are considered. The axle shafts of ZIL-150
had fatigue defects after 2,000 to 85,000 km. Standard
axle shafts of ZIL-151 could not be used after runs of up
to 75,000 km. These standard shafts are made of 45 Kh,
40KhGR, 40KhGT, 35KhGS and 40KhNMA*steels. Axle shafts that
were reinforced by shot-peening did not show any fati6ue in
cross-country test runs after 96,000 kiii. They also endured
cycles of up to 1,200,000 to 1,500,000, while the standard

Axle shafts of ZIL-585 were tested on first-class roads, dirt
roads and in cross-country rides. They succumbed to fatic-ue
after 82,000 to 101,000 km, but in one instance this was al-
ready found after a run of only 34,500 km. The author con-
cludes that new calculation methods and additional reinforce-
ment will increase thelife and fatigue resistance of these
axle shafts.

ABSTIMT: It is important to produce heat resisting explosion proof
dry transformers for the coal industry because they can be
installed much nearer the coal face than can flame-proof
oil-filled transfoimers. For the manufacture of such
trans -fo rmei-s it is important to have insulating cylinders
and tubes capable of operating at high temperatures and
voltages. This article describes briefly experimental
data on the production and study of heat-stable glass-
fabric cylinders and tubes based on silicone resins.
Polyphenyl-methyl-siloxane resin of high thermal and water
resistance and satisfactory binding properties for glass
cloth was manufactured on a semi-industrial scale, This
Card resin was introduced into production at the Kuskovsk Chem-
1/3 ical Works under the brand Varnish K-41, which was later

modified by poly-ether r1-4 and used for the impregnation
of glass-cloth used in the manufacture of wound glass-
cloth products. The technology of production of cylinders
and tubes from this material is then described briefly7a
Figs .1, 2 and 3 show the changes in the-dielectric proper-
ties of these cylinders as a function of the time of wett-
ing, and Fig.4 the change in capacitance of the cylinder
with the time of wetting. The cylinder with a wall thick-
ness of 5 mm was placed in water and kept there for 41
hours (after it had been first exposed to a humid atmos-
phere). Its loss angle did not change'. It withstood a
voltage of 30 kV for 5 minutes. It was then heated for
two hours at 200 C and was tested at 30 kV for five minutes
at this temperature'. Further increase in the voltage to
47 kV caused breakdown.
Glass-cloth cylinders were tested both in the initial con-
dition and after ageing at temperatures up to 220 C'. The
results of the tests are given in Tables 1, 2 and 3~-
Card Samples 1 and 2 withstood a test voltage of 20 and 40 kV

wetting for three days, Table 2 gives the results of
tests on cylinders after maintaining for a long time at.
a temperature of 200 C with periodic wetting. Table 3
gives results of tests on glass cloth cylinders after
periodic heating to a temperature of 220 C and e-r-posure to
a medium of relative humidity of 98%_. All the cylinders
withstood the test voltages of 20 and 40 KV before and
after wetting and after ageing for times up to 500 hours.
Table 4 gives the results of tests on the dielectric pro-
perties of glass-cloth cylinders used,as the main insula-
tors in a dry type mining transformer. A dry type trans.-
former, TOO-180.760'of-180 kVAj 6000 V + 5% was made.
Daring the process of testing, this traEsformer 'was often
overloaded two or three-fold in respect of current and to
double output'. In these difficult conditions the trans-
former continued in experimental service'. This transfor-
mer shouldp therefore, be very,valuable and reliable under

ABSTRACT: The -factors restricting the use of in impedance meters and
charac'ierographs are: spurious AM, relative -phaoe -shift character disperision, and
nonlinearity of these characteristics. These factors are responsible for a side
mirror'.1, frequency which affects the accuracy of measurement. The accuracy can
be, greatl improved by modulating the phase of one of the signals according to a
y
tnore--complicated-than-serrodyne law. Two modulator and one-modulator cases are'
considered. It 49 found that: (1), The double hase modulation essential1v reduces the!
p
error (due to incornplete supprea sion of the -side "mirror" frequency) in impedance
rneters-aj~d_characterographs; (Z) The best accuracy can be expected when two
modulators are used; (3) If one modulator is used, only.the-units generating the
control and. synchronizing signals become slightly complicated. Orig. art. has:

an?'distributions of n,'c, Hm and h were investigated for a given
T ( T - 10 1 1.5 x 10-3 sec. ) and various C by using an experimen-
tal set-up that comprised a sound-frequency source, a noise source
( f - 50 kc/s, & f - 5.5 kc/s ), a mixer, an IF amplifier ( f . 140
kc/s, 6f - 1-5 kc/s ), a bilateral limiter and a frequency detector,
the input being either noise alone or -noise plus signal of various
SIN ratioKs. The result of statistical,processing of 500 frequency
oscillogr&MB are shown in the form of tables and curves and agree
well with theoretical results where available (for n and -C ).
Thus the T, distribution tends to an exponential distribution as
C increases. There are 2 tables and 9 figures.

ABSTRACT : The regults of an experimental study conducted on a hookup
described by 'V. A. Larlkov, et al. s earlier (Elektroavyaz, 1963, no. 11) are
reported. It it; found that, under no-modulation conditions, the tii.ie of the
transient. pr~>cez;r in a heterodyne oscillator increases when a noise is present;
even with a low noise level, but with a high initial detuning A f. the transient time
exceeds that of the no-noise case by Z-Z.5 times. Also, the noise narrows the
lack-in and holding bands of the AFC system. Two measures to offset the effects
of nbise are recommended: (1) To utilize only a small part of the lock-in band
