1000 Mc/s at temperatures from -195OG to 20000. Samples without visible
defects were cut in such a way that theirfaces were perpendicular to
the :.t, Y and Z axes with an error not greater than 31; the opposite

ultrasonic w-aves 'were excited using electrodes of 5-10 mm, dimensions
placed on the crystal surface and fed with pulses from a high-frequency
generator. A strong electric field produced in this way at a crystal
face induced vibrations of this face which were propagated as sound
pulses into the sample. The exciting electrodes -were used also as a

along the X and Y axes are shown in Fig 1. To excite longitudinal Aaves
along the Z-axis It was neceesar to employ the usual techniquG using
acoustical pie zo -vibrators; this limited the range of froquencios to
200 11c/s. Figs 2, 3 and 4 show the measured values of the absorption
coefficients for shear and longitudinal viaves propagated along the X, Y
and Z axes respectively. All.the absorption coefficients were
apnroximately proportional (except 'at the lowest frequencies) to the
square of the frequency. The losses, represented by the absorption
coefRicients, can only be partially explained by thermo-elastic
relaxation or by motions of dislocations in one atomic plane. Fig 5 shovis

and 135 (curve 8) Mc/s . The weak dependence of the absorption coefficient OL
on tamDerature shows that the diffusion processes are not pred=inant in
absorption of ultrasound in the range of temperatures employed. The
temporature dependences show no definite relaxation maxima; in particular
the relaxation peak reported by Bommel, Mason ard Warner (Ref 1) at
c0= :Lol3exp(-1300/RT) was not observed. The increase of absorption at
lovi temperatures (Fig 6) was less than expected. The pulse technique

TITLEs Ultrasonic Studiesallon Deformed NaCl Crystals
PERIODICALs Akusticheskiy zhurnal, 196o, vol. 6, 1~o. 2,.pp. 244-251
TEXT: In the experiments under consideration the authors carried out
the same measurements and pretreatment of crystal samples as L. G.
Merkulov. Thecrystals were deformed along the crystallographic direction
(1001. The authors studied the dependence of sound absorption on the
degree of deformation in the same direction at frequencies of 5-200 Mc/s.
The dependence of the absorption coefficient on deformation is graphical-
ly re resented for two crystals and frequencies of 16 and 80 Me/s
(Pig. 15. A linear dependence was found to existi The authors examined
the deformation dependence of absorption in a wide frequency range in
order to clarify the mechanism of absorption. Results are graphically
shown in Fig- 3. The resulting curves differ considerably from those of
undeformed crystals, since a maximum of resonance appears Which is
flattened with increasing aging of the sample and is shifted toward

higher frequencies. Nextq the authors give experimental results on the
absorption of longitudinal and transverse waves in crystals through
which ultrasonic waves pass in various directions. The results are
given in a table and in the diagram of Fig- 4- Furtherg the changes of
the absorption coefficient in aging for various.plastic deformations
-are graphically shown in Fig. 5. A comparison-is made between
absorption in deformed and undeformed crystals, and the theory of dis-
locations is discussed, which offers an explanation of the dependence of
absorption on the type of wave and on the direction of propagation.
The behavior of J7aCl crystals in absorption is described with the help
of the theory of dislocations. Finally, a r6sum6 is giveng in which it
is stated that the ultrasonic technique makes it possible to detect small
changes in the orystal lattice. The authors point out that measurements
of absorption and ultrasonic velocity will help to clarify the nature of
dislocations and lattice defects. There are 8 figures, 1 table, and
9 references: 3 Soviet, 4 American, 1 German, and I British.

ABSTRACT: In.measuring the velocity of elastic waves through solids, an acoustical
contact between sample and sound transmitter is achieved by means of an oily or
adhesive layer. Because of the thinness of this layer) its effebVis generally
but this neglect may lead to 'cons iderable error. The fauthors have
analyzed the sy3tentatic error arising from the presence of conti~t layers in the
pulsing arrangement. used for measuring velocity on the principal:6f direct trans-
~mission of sound. It was found,that for steel,samples, -at a frequency of 1.54
meg!~raycles and with transformer oil.constituting the contact layer, the time lag
was 0.065 microseconds. For quartz samples the lag was 00032 microseconds. By
using various frequencies the authors found that the equivalent thickness of the

contact layers dobs not depend on frequency* They found a single-valued relation
between equivalent thickness and.unevenness of the layer. By knowing the maximum
value of unevenness, it is possible to compute the equivalent thickness and to
introduce a correct-ion. This permits a great increase in accuracy when measuring
ultrasonic velocities. Similar results were obtained in studies on transverse
waves. Orig. art. has: 4 figures and 2 formulas.

Title The velocity of the wave front in nonlinear electrodynamics
Periodical Zhur. eksp. i teor. fiz. 28, 246-248,.February 1955
Abstract In the works of D. I...131okhintse,v (DAN SSSR.. .82, 553,,1952) and of Blokhint-
sev and V. V. Orlov 0~1w' 25 513, 1953):it ~as shown that in nonlinear
electrodynamics and mesodynamics. the propagation of asignaldefined as the
surface of a weak-discontinuity in tfie field intensities can occur with a
velocity greater than the velocity of 'light-in'a vacuum (the problem of the
change in the velocity of propagation of light in nonlinear electrodynamics
was considered torthe first time by M. S. Svirskiy, Vestnik MSosk. Gos. Univ.,
3, 43, 1951), both works employing-the method of characteristics of a system
of differential equations in partial derivatives.. The author presents a sim-
plification of this method and some further remarks on this important problem.
The aW"hor notes that all of his results"can be obtained by forming the dif-
ference during transition through the surface of discontinuity for the diver-
gence of the energy-momentum tensor. He thanks Prof D. D. Xvanenko, who
pointed out the importance of the subject.

In view of the fact that computation to be carried out in consideration of all
conservation theorems is very difficult, various methods of approximation are
used. On this occasion the value = t ~ M is assumed as the maximum
En i=1 i
limiting value for the energy of a particle. E - total energy of the colliding
particles, Kmi - sum of the rest masses of all particle products vrith the excep-
tion of those given). Here it is shown that these values must diminish in the
manner that follovis from the conservation theorems of momenta and of energy. The
computation of tho maximum energy and the maximum momentum of each product leads
to the determinatLon of a hereby caused maximum. Computations are here carried out
in the center of ioass system. If it is assumed that' on the occasion of a collision
n- n-1 _>
a total of n particles is created, then E + + k = 0.

Here ti, k iand vi denote the total energy, momenta, and. velocity of the i-th par
ticle product. The corresponding quantities of the investigated particle product
have the index n.
In thecase of a maximum k. the momenta of all (n-1) particles must be opposed

The Velocity of the Wave Front in Electrodynamice With Ifigher

vysshimi proizvodnymi)
Zhurnal eksperimentallnoy i teoreticheakoy fiziki, 1958,
Vol 35, Nr 3, pp 782-783 (USSR)
The velocity of the wave front in the electrodynamics of
Maxwell (llakevell)-Lorentz (Lorents) and in non-linear elec-
trodynamice were investigated in some previous papers (Refs 112)
In some of these papers the method developed by Levi-Civila
(Levi-Chivita) was used which is.the simplest and most de-
scriptive. The author applies this method to the investigation
of electrodynamics of higher-derivatives. This paper deals
only with differential equations of the fourth order. First,
the general form of the equations of electrodynamics with
higher derivatives is deduced by means of the Lagrange (La-
granzh) formalism. The Lagrangian L (denbity of the Lagrangian)
is assumed to depend on1he2 invariants 1 1 ~ Hik H ik /21

H k A- . - A i,k' This relation leads to the first groups
oi e=quafllons:
Hik,l + Hkl,i + Hlilk ~ 0. The second group of equations is
deduced by means of the variation equations

expression for the second group of eqiiatilons is given ex-
plicitly. The wave front is a surface of a weak discontinuity.
In the given case, all the Hik and their derivatives, with
the exception of the highest ones (i.e. Hik,lmn) are dis-
continuous. The author investigates a plane wave front.
H14 (X 3'X4 ) and H13(X3'X4) are assumed to be different from
zero. By some operations# the following equation is deduced:

TEXT. An instrument is described here with which the reac,~ive and active
component of the internal resi!~tance of an antenna-feeder"'Avice in the
range of from 10 to 100 ohms may be determined. The wave range is between
200 and 2,000 m. It operates by the resonance method and consists of a
generator , a power amplifier, a measuring circuit and 2 indicators. The
block.diagram. is shown in Fig. 1, the detailed diagram in Fig. 2. The
weak generator operates with an inductive feedback, the power amplifier
is a cathode follower and the measuring circuit is connected with the
power amplifier by a high-frequency transformer. The parasitic
-capacitances are the main cause of errors of measurement and their
reduction through constructional measures is discussed. The measuring

circuit is provided with a resistance box and the authors discuss the V
construction in detail. The capacitance box is also described in detail.
The voltage at the primary coil of the transformer and the tuning are
measured by the 2 indicators. The rectifier circuit (Fig. 4) is discussed
next, the measuring process is described finally, and some practical
advice is given. A checkup in a laboratory produced satisfactory results.
There are 5 figures.

The work contains a theoretical and experimental investigation of the most widely
used modulator circuit, that the filter coupling to the load " and also an investigation
of the~operation of this dircuit in the presence of back-coupling. Linear distortions
are considered here which have the greatest weight, due to periodically repeated
transients in the plate cirucit of the output tubes_of the modulator, which operate in
class B. This investigation has made it possible to derive formulas for the calculation
of the coefficient of nonlinear distortion in circuits with and without back-coupling,
and also to conclude that the stray inductance of the half of the primary winding of
the output transformer; has the dominating role, as well as concerning the role and
and magnitue of the resistance used to damp the circuti for the even harmonice, along
..with many other conclusions, which, in particular, make it possible to reduce the di
dimensions and cost of the modulation transformer.
