PLRPOSE AIND GOVERIGE: This book summarizes the general knowledge of purpose of tech-
nology of processing, use and physical and technological properties of metal-ceramic
materials. The results are given of deformation and disintegration of similar ma-
terials; and their explanation is given, based on the statistical theory of durabili-I
ty. The methods are described of technological testing of mctal-ceramic materials ati
room and high temperatures. Special attention is given to high-melting metal-ceramic!
materials containing small amount of plastic at a very high temperatures (up to
3000'K). The book is intended for engineers and scinetists studying the propertLes
of metal-ceramic materials, as well as their intrr,-,-,.-., T,,Ion into industry, and for
students at higher technical institutes.

1 The final duct contour Is selected only after testin;z a-,d -ca:;,cns

inlet ducts is quite difficult, the Leningrad PolyteChlliC InStitute

,of centrifugal compressor inlet ducts. The geomatry of teste--; ducts is
shown In Fig. 1. The object of the Investigations was to deternine

Nikitin attempts to draw some conclusions from
the study of solar flash spectrum during an

He absorption line 10,800 A in the solar disc

of neutral He as due to agglomeration of,He at-ama
in metastable state, He hopes that further study
of this line will yield new data. Received

TITLE: Some Characteristics of CaIl, Ball and SrII Lines in Stellar
Spectra
PERIODICAL: Uch. zap. LGU, 1958, Nr 273, pp 14 - 29
ABSTRACT; Some specific features of the Call, Ball and SrII spectra are
c.Nnsidered, which are significant for estimating the line inten-
sities of these elements in stgllar spectra. The ground levels
are., 42S for call; 6 S and 5 S for BaII and SrIl; the meta-
stable levels are 32D; 52D and 42D. The metastable 2D level
is close to the ground 23 one. Quadrupole transitions as well
as transitions due to Inelastic collisions with electrons are
possible from 'he 2D level to the 2S one. The numbe-:, of re-
combinations to the 2D level is greater than to the 2S level
by almost two orders of magnitude. These peculiarities of the

mechanism of electron capture, two-electron recombinations, is discussed,
and its effect on the rate of formation of CaI, BaI and SrI atoms is clari-

ABSTRACT: In an earlier paper (Ref 1) the author stated that the intensity
of some lines in stellar spectra does not only depend or, the
excitation and ionization of the outer, but of the inner
electrons as well. As may be seen from another paper (Ref 2),
the nonradiative transition, the so-called au"nionization, is
considerably more probable with light elements, than is the
transition with radiation emission. On the assumption that a
radiation field exists in the stellar shell, which is capable
of ionizing the atoms, the conclusions are summarized in three
paragraphs. They deal with the distribution of the atoms among
the various ionization states, the ionization of atoms by
ejection of K- or L-electrons and, the autoionization of light

PERIODICAL. Doklady Akademii nauk SSSR, 19609 Vol. i,2, No. 1, pp. 99-90
TEXT: 9-111 emission lines were observed in the spectra of W-R stars; several
novae, and several planetarl nebulas. These lines are diTided lato two grcups,
the first of which comprises all the lines produced by transitions between levels
with the nonfigurations 2s2 + n (a,p,d,f, ... ). while the spoond group includes
the linea caueed by transitions between levels with the oonfigurations
2s2p(3p) + n (s,p,d,...). The :rirst group of lines is explained b~ the joint
action of recombination-and fluorescence mechanism. The explanation of the 3econd
group meets with great difficulties due to the fact that in the recombination
mechanism ar. electron must be captured by an N-IV ion, which occurs not in the
state 28 2 1S02 but in the excited state 2s2p 3P. Considerations of steadiness

make it possible to draw conclusions as to the comparability of the number of
ionizations of the N-III atom by ejection of a 2p electron and formation of N 17
in the state 2a2 1S with the number of its ionizations in the case of ejection
of a 2s electron and formation of N IV in the state 2aPp 3P. Next, the author
studies the conditions under which comparability is atl;ained B using
Planck's radiation law he obtains the formula 1 1 + 21 kT + 2~kT~2 ,
W/ a 12exp [(,1-,2) /kTJ (1), where 12 - 47-4 ev and 1 1 55.8 ev are the ioniza-
tion potentials of N III with ejection of a 2p- and 29 electron, respectively;
and a -2. When T is between 105 and 2.105, this equation permits both types
of the above-mentioned ionizations of N III in equal parts. It is therefore
possible to assume such a high temperature for the objects under considera-
tion. Several intensity ratios betwee-,i the two groups of lines of several
astronomical objects are given. There are 6 references, I of which is Soviet.

TLKT: It is noted that the following NIII multi2lets are

2s5y3,SDr)on~2,2,,2,c - 2s23p2p) and (2s24f2F - 2s25g2G). The mean

wavelengths for these multiplets are 7CI = 464401 T 2 - 4100 and
~13 = 4379 1% In view of this, numerical ca'lculations were carried
out of the intensity at theae wavelengths +relative to the 1113 line.
The results were then used to calculate n for sbc nebulae
.(n+ -number of NIV ions in the ground 2sAg . state, ne - electron

ABSTRACT: Until now, the recombination spectrum of 0 111 was com-
puted under the assumption that Vs energy levels are determined by
the LS-coupling. The author has investigated to what extent this
assumption Is valid for all levels. Some qf the results are reported
in this communication. Since the 1D and ~F-terms are overlapping,
an intermediate coupling, rather than LS-coupling, is indicated. The
probabilities of intercombination transitions in the visible and ul-
traviolet spectrum regigni have been computed. In some cases (for
Instance# 2P3d3F2 to 2P D2), the probabilities are considerable,

and cannot be neglected. Most of the lower levels are well-do4cribed
6y the LS-coupling, ThiG Is not true for higher levels. Apparently,
'the intermadia coupling apRliss for some of these levels. fhe an-
1~ozelous population of tba -1p2-level may also be explained by the
deviation from LS-coupling. Orig. art. has: no formulas, tables, or

Uniqueness of Eydsting Force Methods of Calculatint, Differential and
Planet-try Mochani5ms
By analyzing several force methods of calculation the -tuthor con-
cludes that the determinatior of frictional losses is always ba!-ed on a
-onsiderition of the "potential" pa-rer (the po-jer under whose conditions
of transmission the paeticular gear drive is operating). He indicates
the -eneralized formulas and shows that formulas of other authors ~an ~-,e
~Ierlved from them as special cases. Using a differential mechanism as
an ex;4mple he shows that calculations based on different methods can
