that the least square criterion for the deviation of thh unfulfilled condi-
tions on the contour from zero (or a given value) be ustA. In studying the
deformations and forces in a square cylindrical hollow panel under the ac-
tion of a uniformly distributed normal load and under boundary conditions
for a movable hinged support, it was found that the best point of colloca-
tion in solving the problem in the first approximation is a point with the
coordinates x = y = 0.4164a, where a is the size of sides with the coordi-
nate origin in the center of the panel. The solution obtained is compared
with the solution of the same problein by ~he Bubnov method when all boundary
conditions are satisfied exactly. E. 1. Sokolov.

Abstract: The structure and properties of molybdenam crystals
with orientation of the 100.);, growth nxes, containing
0,02 and 0.03 wt. % carbon, are studied in the 77-2930K tempera-
tare interval. A decrease in the carbon content within these
limits causes a sharp increase in plasticity of the crystals,
particularly at low temperatures, a.decrease in the yield point,
and a decrease in the dependence of:yield poinvon test tempera-
ture, as well as more even distribution of dislocati'ons and
superior crystal structure. The strong dependence of yield
point, relative eiongntion, relative reduction in area., and
nature of rUDture of crystals on the orientation of the rupture
axis is confirmed,

Translation: A study was made of the attenuation of elastic vibrations of

function of their plastic deformation (1-27fa) and as a function of the
content of alloying additions of iron and silicon (0 -03"-0 .9 Wt -%) - It Was
established that the attenuation coefficient is unaffected by slight degrees
of deformation or alloyirg. With high degrees of defox"o-tion (9-27%) the
attenuation coefficient increases sharply. Data on ultrasonic attenuation
are compared with the results of a study of single-cryste.1 fine struature

Translation: In contrast to existing niodels, a plan for the nucleus of spin
detonation is suggested, the basic clenient of which is the finite front oi
self -sustaining detonation located between the foJlowing generalized configura-
tions of shock- -detonation discontinuities at its ends: binary t.,,ith combustion
in the direct self-sustaining wave and trina-ry with coribustion in two waves
(direct transverse self -sustaining and slanted supercomprossed). The leading
process in the propagation of detonation spin is consid-,,red to be the self-
sustaining detonation front which accelerates the combustion products to the
speed of sound relative to its leading. edge, so that the rarefaction waves
follot-ting it have no influence on the detonnion front.

The problem of construction of the structure of deton, spin is solved under
one additional condition: during propagation of spin detonation thrOU'll the
tube, due to the absence of a swimary moment of externiLl forces, the momentum
should remain constant. In the planar case, this condition is reduced to the
condition that the projection on the plane of the cross section of the striman.
momentum vector of the gas disappears in the area of the nuclous of spin do-
tonation. T'he initial data foe calculation used were the Mach number of the
gas mixture and the slope of the trajectory of the trin.,;iry singular point to
the transverse cross section.
The solution of the system of three trans cendental cquations with Variable
adiabatic indices formed was produced by a combination of the mlethect of stic-
cessive approximations with the coordination descent mothod. The results of
calculation of the parameters of the spin detonation nucleus for a uiixture of

Kiev, Gidromekhanika, Akademiya Nauk Ukrainskoy SSR, NoIl, 1972, pp 46-51
Abstract: Theoretical investigation of turbulent mixing of tijo semiirfinite
high-velocity, high-temperature gas streams is performed. Compressibility is
taken into account. Viscosity effects are neglected.
The analysis is based on the continuity equation and two anergy equations.
After several transformations the eq-uations are put into the f orm of a
Tollmin equation (21) and a differential equation (22), Wi(ch are thQn
solved using the boundary conditiolis.
The analysis results show that an increase of adjacent 6;tream's; velocity is
equivalent to a decrease of its temperature and causes the dearease of the
angle between the turbulert zone boundary and the line of contact.
