TITLE: Transient Processes in Linear Vibrators (Nestatsionarnyye pro-

PERIODICAM VeBtnik Leningradskogo universiteta. Seriya fiziki i khimii,

ABSTRACTs The present paper is a part of the dissertation written by TT,~
Krasil InikcFv. G.I., Makarov suggested the problem and helped cla a
number of quistions. The authors investigated transient processes
in thin serials '. Paragraph I deals with the problems arising in
the theory of thin aerials, Although the basic investigations on
the steady theory of thin aerials have been published already
soffie time ago (Refs 1,2) discussions arose in Soviet and Ameri-
can technical publications (Refs 4-8), dealing with the formula.-
tion of the integral equation for an aerial with a so-cqlled gap
The transient excitation of a thin cylindric aerial (� 2) as weil
as transient current waves in the aerial (� 3) were investigated
From the practical point of view 2 facts are of particular im-
portance in the investigation of transient processes in various
syitems: 1) the behaviour of the system during the initial mo-
Card 113 ments, especially the investigation of the first half waves of

Transient Processes in Linear Vibrators SOV/54-58-3-5/19
the signal, 2) the characteristic of the process as a whole and
the determination of the time after the lapse of which the sys-
tem becomes steady. Paragraph 3 gives the answer to the first
question. The current in the direct and in the once reflected
wave was found in the first approximation. Transient distortions
were found only in a small domain around the front. These tran.
sient phenomena which depend on the diameter of the serl-al musi
be considered in the examination of the signal front. As regardp
the second problem, it appears that from principal cons2derationp
repeatedly reflected waves must be investigated and the constant.
ly increasing transient process in the range of the front has ~.o
be considered, In the case of thin aerials the real transient
process can be assumed asymptotic. In the case of an arbitrari,y
thin aerial the transient distortions in the range of the trav-.-
ling wave front are completely absent. As the radius of the aerial
is insignificantly small, it can be assumed that the transient
characteristic impedances introduced in � 3 adopt their definite
values Z(z) from the very beginning. For this reason the .7oeffj
cient of reflection on stead as well as on transient c~ondition6
Card 2/3 differs only little from (-1~ and can be replaced by the steady

2i or.
formula K a 0. The interaction of the reflected waves witn thoR-
0
generator must be considered as well. This is possible if the
considerations are started from the simplest quasisteady case.
The summation of all travelling waves must yield the steady con-
ditions in the vibrator. According to the suggested method tran-
sient processes in thin serials can be thoroughly inveBtigated
also ofi-the occasion of more complicated cases. The analysis does
not become too voluminous if in the case of a sufficiently low
ratio two basic classes of transient processes in aeria2s which
are determined by the longitudinal and transverse dimensions are
investigated separately. The transient phenomena in the field of
the aerial (above all in the distant zone) can also easily be irk-
vestigat6d. Work on these calculations is under way. There are
7.figures and 22 references, 12 of which are Soviet.

Graphs show that 'displacement currents introduce an attenuation of'
the amplitude of the non-stationary part of the field and that the
amplitude.of-transients depends on the current spectrum in the di-
pole.- From graph of ReV it is seen that transients may introduce
considerable distortion in the propagated signal. It is stated in
conclusion that the problem,of propagation of pulse signals ovet
the surface of the barth is also of practical interest, In that it
gives the picture of signal distortion and that the results obtain-
ed could be used to solve the problem of the inverse diffraction
problem and that from measurements of the delay time of the maximum
of the signal, having other data availablep one could determine
the conductivity of the propagation path. There are 6 figures and

both the delay and the signal shape are changed. From the point of
view of overshoots there exists a certain optimum value of ~t. This
value is R opt 0.25. Fig. 6 shows U (T) with input signal

mainly forriC --*l. The derived exact expression (26) allow not on-
ly certain physical phenomena to be demonstrated but are also use-
ful as a means of checking the accuracy of approximate expressions
derived earlier by the authors (Refs: 1, 2; Op-cit.). The main term

describes the process more accurately than the expression obtained
earlier (Refa lp 2z Op.cit.) and is handier in calculations. The
case of a unit impulse input is then considered. There are 8 figu-
res, 3 tables and 4 Soviet-bloc references [Abstractor's note:
Ref. 4, although in Russian, is a translation from an English-lan-
guage publication].

TITLE: The effect of a complex shape periodic signal on a
free-running oscillator
YLTIODICAL: Radiotekhnikag v. 16# no. llp 1961, 59 - 44
TEXT: The pure theory of phasing of oscillators presents difficul-
ties which make the solutions of its problem practically impossible.
In the present articles the author considers the solution of this
problem in its numerical contextp by means of a fast electronic
computer. Such a problemp as opposed to the purely analytical onep
is stated to be comparatively eaByp but the quasilinear method of
analysis is applied for simplification and numerical substitution
of the equation of the osciilator, upon which acts the external for-
ce A(T). If x is the voltage at the gridp reduced to the amplitude
