ABSTRACT:' The presentwork is concerned with the problem of determining the rela-
tion between the observed and true absorption spectra of molecules in a condensed
medium. in the framework of the Lorentz and Onsager-Boettcher models for the mole-
cule plus medium (solvent) system). In earlier papers (Optika, i spektro,, 14, 28,
1963 and Doklady AN SSSR, 145, 1025, 1962) the authors derived a general equation
for the true absorption spectrum in terms of the observed spectrum,, the correction
for the universal influence of the effective (internal) field, the components of
the tensor of theeffective field parameterp and the direction cosines of the
dipole moment of the transition. In the present paper,, specific but generally
applicable calculations are performed for the case of isotropically polarizing

absorbing molecules. It is shown that, depending on the properties of the mole-
cule and medium,, there.may occur different phenomena which may distort the true
spectrum: shift the bands and alter their intensity and shape. The specific case
of the absorption in -the region of the fundamental frequency of a hypothetical
liquid-molecule is examined and the effect of corrections of the effective field
according to the Lorentz and Onsager-Boettcher theories is shown. It is predicted
that appreciable changes may be expe9ted in the electronic spectra of strongly-
absorbing substances, such as-dyeslbIt is pointed out that failure to allow for
the distorting effects of various factors may lead to serious errors in interpret-
ing experimental spectra. The authors plan to discuss the properties of some

TEXT: The problem of non-linear IflutterO of thin cylindrical
1. panels,.consisting of several elastic orthotropic layers (T.E. Hess-
A.'Rocket Soc. Jour. no, 20 1961) is examined on basis of the mono-
graph of V.V. Bolotin. It is assumed that a stream of liquid of
high supersonic velocity flows on one side of the panelf while sta-
tionary-air is applied to the other side. The equations of the pro-
blem a e reduced to a nonlinear system in terms of the potential
function c and the normal dioDlacement w. An approximate method has
to be aao5ted for the solution of this iTystem. By means of the Ga-
lerkin methodg a system of non-.;linear differential equations is ob-
tained. These equations are applied to several particular cases.
There are 3 figures and 1' table.

The author extends thq theory of nonhomogeneous coverings composed of an
odd number,of lgXers7,*by the correspondence of thin, isotrope, homogeneous
c 'erings7-'iestablished by the static-geometrical analogy. These layers

are arranged symmetrically as related to the m9dium thickness of the
covering surface (geometrical and elastical symmetry). He starts with the
hypothesis that each component layer Is homogeneous and isotrope, following
the physical law of Hooke, and accepts the hypothesis established in [Refs
2 and 3], on the base of which the layers are firmly fit together. He con-
siders the following hypotheses of [Refs 2 and 31 to be valid: a) The
hypothesis of nondeformability of the normal element located on the medium
surface of the covering; b) the hypothesis of the nullity of the unitaz7
normal stresses located on the equally distant surfaces against the medium
surface. Based on these hypotheses, the values of the 6 order in

is referred to an orthogonal system of coordiiiates ( d- , 13 ), and z is equal
to ~, constant representing a certain surface parallel to the considered
medium-surface. He indicates with "J" a certain layer out of the considered
2n + 1 layers (n - 1,2,3,...) and the statical, physical. aAd geometrical

ture are rigidly fixed together to deform as a whole; and b) the Love-Kirabhoff
hypothesis remains valid for the structure as a whole. A certain layer out of
the m considered layers is notated with J, whereas the plastic physical and geo-
metrical values are provided with the index J, while the forces and moments de-
pend on the tangential and bending distortions. The lower surface of the n-th
layer taken from the external limiting surface of the structure is considered
to be initial, which is then referred to an orthogonal system of coordinates,
generally non-conjugated. The reciprocity principle of Betti (Ref. 9: A. L.

the statio-geometrioal analogy and appliesit to the investigation of the stress
state of structures of little curvature, oonsidering the existence of a surface
load and a non-uniform temperature field. Starting from the equations of equi-

TEXT: A theory is described which deals with the stress component
of multilayer shells of arbitrary formq consisting-of several elas-
tic isotropic layers and disposed in an arbitrary way with respect
to the initial surface of the shell. The shells are considered to
be loaded with an arbitrary surface load and to be in the presence
of a non-uniform temperature load. The theory prop 'osed is construc-
ted on the hypothesis introduced into the theory of multilayer
shells by S.A. Ambartsumyan and E.I. Grigolyuk: 1) The raterial of
isotropic and homogeneous layers in the form of a shell is subject
to-Hooke's law; the possibility is excluded of one la er creeping
with respect to another at the surfaces of contact; 2~ Por the she2l
under consideration the Love-Kirchoff hypothesis holdso By conside-

ring that the homogeneous equations of the equilibrium of shells
and the equations of conjunction, and also the relation between the
shearing forces and the functions of the shearing f6rces, and bet-
ween the deformations and displacements have the same form, the au-
thor introduces a statico-geometric analog. The introduction of
this analog permits the number of unknown functions to be reduced
by two times. The general equations of the non-homogeneous shell
under consideration are written in complex form through the intro-
duction.of complex forces and moments analogous to that which was
first realized by. V.V. Novozhilov (Izv. AN SSSR, Otd. tekhn. n.,
1946, no. 1, 35-48). for homogeneous and isotropic shells. The pro-
blem of determining the stress coefficients of the shells leads to
that of determining the complex tensor of stress through whose com-
ponents, and with the aid of simple operations, the components of
ihe shearing forces and the moments are determined, together with
the displacement and deformations of the original surface of the
shell. A detailed consideration is given to the theory formulated
for such shells by A.A. Golldenveyzer (Prikl. matem. i mekhan. 1945
v. 9. not 6', 463-478) and the statico-geometric analog used in the
general case which permits the two-fold reduction of the number of

elastic divergence in the case of lifting surfaces of a constant
cross-section taking into consideration the spanwise moment

hypothesis of A. A. UmanskiyLAbstracter's note: Umanskiy's

TEXT: Vibrations and stability of circular cylindri-
cal shells are considered, formed of s elasti.c-orthotropic-layers.
The resolving equations of the problem are derived on the following
assumptionst a) The layers are rigidly connected so thatthe shell
is deformed as an entity;. V) the Love-Kirchhoff hypothesis is valid;
a) the curvature of the shell is small.' In order to reduce the prob-
lem to a system of equations in the normal.displacement w and the
stress function o, the method given in the references is adopted.
Thereby the tangential stresses T are expressed in terms of the func-
tion..o and the functions P I and P2 (which are* particular integrals
of an equation obtained from the equilibrium- and compatibility
