On the Solution of the Kinetic Equation for the Transfer of Neutrons or
Quanta With the Method of the Partial Probabilities
one. The second part of this paper contains an expression for
the Green (Grin) function of the kinetic equation which has
the form of multiple Integrals. The above-mentioned equation is
solved according to the usual method of the successive approxi-
mations which gives the possibility to obtain successively the
solutions after 0, 1l 2 ... X oollioions. In the third part
of this paper the results of the second part are generalized to
an unsteady kinetic equation. Then the author reports on the
solution of the kinetic equation for the transfer of gamma
quanta and for the diffusion of thermal neutrons. This equation
is nearly totally equivalent to that mentioned in the beginning
of this paper. Then the Green (Grin) function for the diffusion
of thermal neutrons is given. The fifth part of this paper
deals with the moderation and diffusion of neutrons in a medium
with constant free path lengthl it contains (as an example) the
deduction of the exact spatial-ernergy distribution of neutrons
which are moderated in a medium with constant free path length.
The diffusion of thermal neutrons is a special case of the
Card 2/4 above-mentioned phenomena. The multiple integration is carried

bn thei"Solution off the Kinetic Equation for the Transfer of Neutrons or

out acoording to the ordinary operator method and expansion
with resped.t to Legendre (Lozhandr) polynomials is Used. The
author shows how it is possible to generalize the above-
mentioned result% to.the case Qf variable free path length.
At last the author r~eports on the hitherto existing methods
which according to the author's opinion have the following
disadvantages:.l) Their f-ormalism does not correspond to the
physical partioularities of the phenomenon. 2) This formalism
does not give the exact solution as a combination pf the
hitherto known functions and operators. The method of the
partial probabilities introduces (in explicite form) a new
physical variable,r the number-of-the collisions of a particle
with.the nuclei-of.the medium, it describes the real physical
phenomenon of the sueeessive transfer of neutrons or gamma
quanta. There are.7 references, 4 of which are Soviet.

TITLE: Change in Time of Spatial and Energy Distributions of

PERIODICAL: Atomnaya energiya, 1960, Vol. 10, No. 1, PP- 5 - 12
TEXT: This is a theoretical study of the time dependence of spatial and
energy distributions of neutrons emitted by a pulsating source. Such a
problem may arise, e. g., in the geophysical detecting of petroleum
layers. First, the nonsteady equation of motion describing the slowing
down of pulsed neutrons is written and solved, after some transformations,
by the method of stepwise integration. The solution obtained is applied to
calculate the energy distribution, the change in time of spatial and
energy distributions, and the mean square (7) of the slowing down mean
free path. The formulas then obtained are again applied tc treat a con-
crete problem with a variable mean free path. The distribution in time
of neutrons of a given energy is shown to follow Pcis~sonls prcbability
distribution in the whole time interval, It may be oeen from the

that, in certain distance and time intervals, the space-energy and tho
energy-time methods are mutually independent with this method of -ore
sampling. Outside this interval there is a correlation between the two
distribution functions, which is formulated. The method of core sampling
by means of pulsed neutrons has found wide application in the USSR. The
layer forming the object of investigation is exposed for a short time to
the neutrons emitted by a pulsed generator, after which the neutron
dt~nsity in the layer is measured for a certain time. Neutrcn distribution

TEXT: The author derives general expressions for the distance-angle-enera
distribution of neutrons in a medium with more than one component of the
nuclear composition. Cases of low nuclear weights and variable effective
neutron scattering cross-section are taken into account. Together with
two previous papers by the author (ZhETF, ~A, 1504 (1958) and the given
volume, page 3), this one contains generalizations of ideas inaugurated by
Plachek (cf. Marshak R. Rev. Mod. Phys., 12, 185 (1947)), H. Bethe (see
below), and M. V. Maslennikov (Doklady AN SSSR, 120, 59 (1958)). The most

ABSTRACT: The purpose of the investigation was to ascertain the effect of a change
in thV. magnetic structure on the anisotropy of the transverse magnetoresistance of
single-crystal gadolinium in a wide range of temperatures. The tests were made orr
cylindrical samples cut along the (1010) axis, with a ratio of room-temperature
resistance to helium-temperature'resistance equal to 20. The isotherms of the trans-
verse magnetoresistance were measured in fields sufficient to produce saturation and
extrapolated to zero field in the sample, so as to exclude the resistance variations
due to the paraprocess. The 'tests showed that the transverse saturation magnetore-
sistance has a complicated temperature dependence and is strongly anisotropic. From
the measured temperature dependence of the transverse saturation magnetoresistance in
fields parallel to [0001] and [1120] it is deduced that the magnetic anisotropy con-

start has a maximum near 30K and vanishes at 230K. Rotation diagrams show that above
250K the transverse magnetoresistance is negative in all directions, and its absolute
value is minimal in the easy-magnetization direction. Below 130K, the rotation curves
show maxima connected with the appearance of the "cone" of easy magnetization axes.
The results show also that a correlation exists between the temperature dependence of
the galvanomagnetic effect and the magnetic structure. Orig. art. has: 3 figures.

TITLE:' Broadening the Field of Application of Power Regener-
ation iA Electric Railroads (0 rasshirenii sfery

ABSTRACT: The advantages of power regeneration in electrified rail-
roads are listed, and its greatly limited application in
practice is noted. This situation is due to the existing
opinion that power regeneration can be applied only in
sections of the railroad where the direct-current traction
subst~tlons are provided with converters able to absorb
the power regenerated by the locomotives. At the present
Card 1/3 time, only the motor-generator fulfills the function of

112-3-5958
Broadening the Field of Application of Power In Regeneration in
Elec,trie Railroads
such a converter. Since the mercury-ar-c rectifier has
many advantages over the motor-generator, however, recti-
fiers are used in substations for all level stretches of
railroad giving up the regenerative b3:aking. Meanwhile,
according to computations and experimental data, surplus
power (power not used by other electric loc~oi,otives)
comprises only 3-3..5% of all the regeneratedpower.
Further analysis of electric railroad operation showed
that the use of regenerative braking should not be re-
jected oh the basis of absence of inverters or units
absorbing power in the substations, since in many cases
the surplus power can be reduced to zero. To this end,
it is necessary to develop measures of an organizational
and technical nature: compiling of computations sub-
stantiating the technical possibility and economic
expediency of power regeneration for a given stretch of
railroad; developing technological techniques for control
of trains (establishing the locations where regeneration
could be applied positioning the brake handle In the
locomotive, etc.1; training locomotive engineers for
Card 2/3 optimum application of power regeneration to control

112-3-5958
troadening the Field of Application of Power in Regeneration in

of locomotives, etc.). In the event computations indi-
cate that there are advantages to employing power
regeneratl4n, and at the same time a surplus of regener.-
ated power will appear, the use of air braking should'be
considered in certain cases. If the graphic timetable
of the train is seriously affdated, then regenerative
braking must be rejected at this time, which should not
cause difficulties if the locomotive engineer has radio
contact with the power dispatch6r and the train schedule
dispatcher.

ABSTRACTt The article contains criticism of professors and high
school teachers in Sverdlovsk on the contents of this perio-
dical.
Professor P.Z. Petukhov of the Urallskiy politekhnicheskiy
inatitut (Ural Polytechnical Institute) pointed out that the
journal plays up the positive experience more than the defi-
ciencies of the higher schools.
Professor A.Ye. Trop of the Sverdlovskiy gornyy institut
(Sverdlovsk Mining Institute) complained that the editor,
when publishing controversial material, does not give his
opinion.

TITLEz Resonant transforms and their properties
PERIODICALt Radiotekhnika i elektronika. Vol.6, No.4, 1961,

TEXTj The article constitutes a resume of the author's
previously published work (Refs. 1, 2 and 4). Transforms of the
form
t t
D M = fl(T) e-' JWT dT and F (t) = ~f(T) e- jWt dT
and their images in the complex plane are discussed. The purpose
of the article is to popularise these theorems without presenting
any new original results. It is shown that these tran.9forma can
be applied for representing the oscillation process in a loss-free
circuit, to the input of which a voltage is fed which corresponds
to the investigated function f(T) and the resonant frequency of
which is equal to the frequency of the transform w. These

transforms can also be applied for circ*.ugits with losses and non-
linear resistances. In the final part of the paper applications of
the resonant transform to the solution of transient processes are
outlined. There are 9 figures and 5 references: 4 Soviet-bloc and
1 German.

TEXT: The work gives the determination of -the resonance transformation of
a given process, and the connection between the resonance-transformed functions
and the spectral functions of this process, as well as their relations to vary-
ing current and voltage amplitudes in an oscillation circuit whose Input value
is determined by the given process. A description Is given of the main geomet-
rical properties of images of resonance-transformed functions, which are con-
stancy of the image length and the dependence of the curvature radius on the an-
gular transformation frequency. These properties are similar to the properties

elastic models of the given process; with the aid of such models the resonance-
-transformed and spectral functions of the process can be determined. A method
is given for calculating and designing the elastic models, and instruments are
described in which the models can be used. Methods are given for simulating
spectral functions and for solving the Fourier integral with the aid of elastic

generally applicablG and that they represent the
experimental results with considerable accuracy. This
is important, because when the uall temperature is very
high and the temperature drop from the wall to the gas is
also high, a relatively small error in determination of
the temperature difference may lead to the tube running
dangerously hot. The article provides a simple method

TEXT: An experimental investigation was conducted on the effect of the tem-
perature factor on the heat exchange and retistance at the turbulent air stream in
pipes. The authors present in their article a detailed description of the experi-
mental method and the experimental unit. The experiments were conducted with a
pipe of 17.82 mm in diameter and 2,620 mm length. The pipe was heated by direot
current supplied to its ends. The wall temperature was measured by thermocouples
applied to the external surface and insulated from the pipe wall by thin mica
layers. For measuring the hydraulic resis-~%ance, the pipe had 14 bores for sampling
the statical pressure. The R-number range ran from 1.17 x 0 to 6.45 x 105, that
of the temperature factor Tst/T from I to 2.5. As an experimental. result, a:-, em-
pirical formula was obtained taking into account the temperature factor effect:

where c, m, and p are functions of X/D,- the author propose to adopt their values
from the graphs presented. According to the expectations, the values of c and m
remain practically constant and equal to 0.025 and 0.8 respectively for x/D > 10.
But the dependence of exponent p on x/D is preserved over the entire length of the
pipe up to x/D = 133. In other words, the authors state that no thermal stab.11.1za.-
tion is observed at the heating of a gas in pipea at great temperature differencea.
The latter circumstance is unexpreated. Besides the measurement of heat emissi-r..
