Seriya fiziki i khimii, 1959, Nr 21 pp 49-62 (USSR) ABSTRACT- In investigating the state of the, terrestrial atmospheref a number of equilibrium states of the gas medium can be found. For the accurate mathematical and-physical description, publications do not yet bring their complete determination, nor'is there a unified standpoint on the physical nature for some of them. In this connectionp this paper considers some basio types of equilibrium and puts forward their exact determination. Above allp those states were investigated which are of interest for the solution of various tasks of the theory of the upper terrestrial atmosphere. 1) Ther modynamic equilibrium: Some basic laws of the classic phenomenological thermodynamics (Kirchhoff) are indicated according to the book (Ref 1). These are integ7rated by a number of rules resulting from the statistic -.onaideration of the state. In Card 1/3 case of an ionization, the lax of Sakh is fulfilled. The Some Types of Equilibrium States in the Terrestrial SOV/54--59-2-7/24 Atmosphere radiation intensity of this.state is determined by a law of Plank (equation 10), the density of energy according to Stefan-Boltzmann (equation 11). 2) Local thermodynamic equilibrium: The thermodynamic e:juilibrium is disturbed by a =~5er of causes which do not allow the simple.iray of consideration, but the latter is made possible by a separate consideration of volume units. 3) The monochromatic radiation equilibrium introduced by the astrophysicists is considered a little more closely. It occurs if the energy of the frGquency is absorbed by any volume element and completely re-emitted by the same element. rn its physical sense) this equilibrium is directly inverse to the local thermodynamic equilibrium. 4) FinaUy, a type of mixed equilibrium is oonsidereds local thermodynamLo aquilibrium and monochromatic .equilibrium exist in parallel at the same time. At the end of the article, the two stationary atates (energetic and thermic) are dealt with. The radiation equilibriums and the connection between all equilibriums mention,?d are discussed here. The stationary state is also considered in its connection with the Card 2/3 distribution of atoms over tho various energy levels. The Some Types of Equilibrium States in the Terrestrial SOY/54-59-2-7/24 Atmosphere equation of the stationary state for a certain discrete atom le-rel is given. This level is exprossed by the statistic equilibrium of various transitions from above and from below, spontaneous radiation, unelastic collision of ist and 2nd order, ionization, absorption. Finally, the author thanks Professor K. Ya. Kondratlyev for valuable remarks. There are 8 references, I of which is So-iriot. SUBMITTED: May 22, 1958 Card 3/3 66302 'AUTHORS: Kondratlyev, K.

TITLE: On the Theory of Thermal Conditions in the Upper Atmosphere PERIODICAL: Aoteorologiya i gidrologiya, 19599 Nr 12# PP 41-48 (USSR/% ABSTRACT: The results of the theoretical investigation of factors deter- mining the vertical temperature distribution in the upper at- mosphere are dealt with. Recent experimental data and theore- tical results refute the conception of a radiation equilibrium in the stratosphere. Data of actinometrio radio balloons show that active radiation changes with the altitude not only in the tropo phere but also in the stratosphere. The paper by Ohring (Ref M is thoroughly discussed. The most important conclusion from this paper-is that the stratoaphere as a whole (between the tropopause and the 55 km level) is not in a radiation equi- librium, Although the papers (16t 20, 24, 36) convincingly show that thethermal conditions of tho stratosphere are primarily controlled by radiation, the problem of the part played by other factors (in particular that of turbulent mixing) has re- mained unclarified up to date. On the basis of the papers Or 301 32) it can be said that &n extensive area of the meso- Card 1/3 sphere (between 35 and 80 km altitude)t from 300 on the northern LX 66302 On the Theory of Thermal Conditions in the Upper SOV/50-59-12-12/23 Itmosphere 0 hemisphere to.60. on the-southernpie nearly in a radiation equilibriume Th-amoat important characteristic of the mesosphere is the circumstance that its thermal o,Dnditions may be subject to a direct Influence of the change in solar activity* Investi- gations in the thermo- and oxosphere show that various authors obtained strongly varying temperatures for altitudes above 100 km. (hie of the causes is the circumstance that there is no connection between the various tempexatures. Strictly speaking, the,term of temperature is only applice.ble to a thermodynamic. equilibrium. In the case of a nonequiLlIbrium gas, it is very difficult to determine the connection between various tempera- tures. The assumption of a thermal equilibrium (Ref 2) at an r- altitude of 100-400 km can hardly be justified. It is more co ' root to speak of part equilibrium steAes with different degrees of freedom* In conclusion, the follolring is stated: It is quite natural to assume that the terrestrial -atmosphere gradually -loses its properties and - at.an altitude of 2pOOO - 39000 km comes into contaot,with the interplanetary gas. On the other Card 2/3 0 handq the temperature of the interplanetary gas is about 5,000 K.

The Fourier series obtained are analogous to previously obtained results (G. Porod, Kolloid Z., 1951, L41; 2) for bodies giving isotropic LASC. Typical examples of LASC are! discussed as well as the accuracy of the calculation of the radial dis- tribution curve and a number of other characteristic paraneters (diameter, curface, and volume of the scat- tering heterogeneities) from the experimental data.

Moscow, AS USSR, 1958, PP 7 - 18 ABSTRACT: To extend the possibilities of the X-ray method of small-angle soa#ering (SAS), the authors propose that a new experimental technique be adopted, using a frame camera, a single- crystal monochromator with point focusing of the primary beam, and various variants of an ionization device with two single crystals. It follows from present-day SAS theory that one can use the formula of Fourier analysis to obtain a number of new parameters in addition to the radii of inertia. The comparison of these parameters, to-. geiher with the simultaneous use ofthe direct results of Fourier analysis,. permits a more complete and unambiguous analysis of the structure of the scattering regions ef inhomogeneity- and, in particular, the determination of their inner surface per unit mass of the sample, (In-t khimii silikatov).

Moscow, AN SSSR, 1958, PP 7-18 ABSTRACT- A short description of a new experimental work on the method of X-ray scattering under small angles (SSA) of the following devices: a) a frame cameraj b) point focusing of a bunch by a monoohromator made of a quartz crystal with barrel-sbaped curved planes; a) a double crystal-spectro- meter with recording ty a counter. Some principal aspects of the theory of SSA are considered. The connection of the functions of radial dis- tribution with the intensity of the diffraction picture is shown. The corresponding pictures for six types of.submicroscopic structure are given. It has been shown that the Fourier analysis by SSA permits to understand the structure of the scattered non-homogeneities. M. Umanakiy/ Ll- Card 1/1 "N / 61 - ~// AUTHORS: Sineltnikov, N.

By means of this calorimeter the actual specific heat a of the material and its heat conductivity land therefore also temperature conductivity a can be determined simultaneously. The calorimeter is surrounded by a concentrically located preheater, which consists of a thin nickel band forming an adiabetic shell around the sample. The inner preheater, consisting of a molybde, num wire, is located along the axis of the cylinder. Thus, the construction of the calorimeter, from the point of view of tem- perature distribi~tion on the sample practically corresponds to an infinite cylinder. The experiment for the determination of the actual specific heat consists in ceding thermostating (mainten- ance of uniform temperature) of il-he sample, supply of a certain Card 1/3 amount of heat by means of the inner preheater and temperature Adiabatic Calorimeter - an Instrument for Simultaneous Determi- 57-1-29/30 nation of Specific Heat and Heat Conductivity. measuring of the sample after the restoration of thermal equili- brium. The feeding of the inner preheater is chosen in a way that in the course of the whole process of preheating the radiation strength of the wire remains constant. Thus, the temprature of the shell will reuain equal to that of theperiphery of the sample (luring the time of the experiment. The measuring of heat con- ductivity which is made simultaneously with the measuring of spe- cific heat is based on the properties of the nonsteady temperature fit-ld of the problem investigated. A formula for ~is derived by means of which heat conductivity cyn be determined in the case that the quantity of the heat flow and the temperature increase at the outer surface of the sample from the beginning of the feeding of the preheater until the establishement of the equili- brium state is known. On the other hand, since the total heat Q. with which the sample was fed, and the total temperature increase of the sampleA t = Lltj + 6t2 were determined the specific heat c - Q/4 t can be computed. bleasaring results for the heat con- ductivity coefficient of powderous quartz at normal atmospheric pressure and at remnant pressures of an approximately 0,5 and Card 2/3 5,jo-5 mm mercury column are given.

In the second case air par- tioipates iia heat exchange, air conveotion, however, practically lacks. Heat transfer is due to radiation as well as to heat con- ductivity of the air and of quartz. In the latter ca3e the air practically does not participate in heat exchanLe and heat trans- for occurs only at the cost of radiationand of heat conductivity of quartz. Conclusively it is stated that with the rise of tempe- rature the Ale of heat transfer due to convection decrease at the cost of an increase of the Ale of radiation.

The application of the theory of Fourier expansion allows to obtain simple and clear general formulae and to relate the theories of x-ray scattering in distorted crystals suggested by various authors. The paper consists of two parts. In the first part the general theory of scattering in crystals containing internal cavities, cracks, and deformations is presented on the basis of a direct expansion of the electron density intDa Fourier series without Card 1/2 introducing atom coefficients.

The latter one, however, ha's a less complex structure and permits to employ the methods of Four'ier analysis of diffusion scattering to a much wider extent. There exist simple rules for the transition between the two variants of the theory. There are 2 figures and 6 references, 5 of which are Soviet.

The value of I W j3 ((be - ) where r is the critical radius of the spherical nucleus and 10, and Og are the ther2ly'namic potentials per unit volume of the crystal and glass, respectively) Is calculated for several examples. In discussing the role of the nuclei of crystallization during the formation of glass ceramics, the author outlines the require- ments resulting from the need for homogeneity and fine dispersion in the ceramic material, and discusses the rate and sequence of formation of nmv phases.

Thermograms of glass are plotted and the problem of the existence of solid silica solutions in lithium disilicate in the crystallization products of glass of high silica content is discussed. The investigation was carried out by x--ray, thermographic and microscopic methods, as well as by means of infrared absorption spectra. Two kinds of samples were studied: Card 1/2 ACCESSION NR: AT4019285 some were found to range from the eutectic composition (30 mol.% U20) to pure S102, and otherswere found to be of a composition ranging from metasilicate to disilicate (36-48 mol.% LiZO). The temperatures of crystallization were 430, 480, 630, 900-960 C; time: 1-100 hours. Some samples were subjected to thermal treat- ment over a temperature range of 430-960 C. The appearance of the different cry- stalline structures (lithium disilicate, metasilicate, cristobalite, tridymite) in' relation to the varying experimental conditions is discussed in -detail.
