PERIODICAL: "Izvestiva Akademii Nauk, Seriva Geofizicheskaya" (Bulletin of the Ac.Sc., Geo hysics Series), 1957, ]NO-5i, pp. 683-688 Ms .S.R.) ABSTRACT: In a previous paper (1) the authors gave the results of theoretical and experimental investigations of the angular distribution of the intensity of atmospheric emission. A number of problems were, however, left unsolved because of a lack of experimental data. In the present paper a more complete account of the above is given. These new results allow some conclusions to be made which are of interest in practice. The angular distribution of the intensity of the effective emission over the sky is characterised by the function ~.(4) = f(IYA)lf, where f(j*) and f. are the intensity of the effective emission at a zenith angle 0 and Card 116 in the direction of the zenith respectively. The distribu- tion of the intensity of the counter-emission of the atmosphere relative to the vertical is characterised by the analogous function 4)(19") = g('~%Vgo. In the case of a 49-5-16/18 Angular distribution of the intensity of thermal emission of the atmosphere. (Cont.) clear sky the theoretical formulae (derived by one of the authors in Ref.2) has the form: PI (woo s e c -L") (Alp) :pj(w OD where PI(wd is the atmospheric transmission function for a directed radiation and w is the wkiter vapour content of a color of the atmosphe?e having a unit cross section (in g/cm ). Further expressions which are available are the following: r (a) clear sky: Cos (empirical) or 0.18 Ym (1 - Cos IP) - 11 ln 10 r(O) rTO7 COS-01 (b) cloudy sky: Cezd 2/6 PI(Wh sect" PI (Wh) 491-5-3.6/18 Angular distribution of the intensity of thermal emission of the atmosphere.

(Conte) that is practically independent of w in the range considered (0.41 to 2.66 S cm ) and is in agrKement with theoretical formulae given above (Fig.2). In the case of the clouded sky the angular distribution of the intensity of the effective emission depends on the water vapour content between the cloud and the Earth's surface and is well represented bythe theoretical expression given above. Fig.3 shows calculat ons of ~ (^01) as a function of -t~l for w. - 0.34 g/cml. At such a small value of wh the distribution Is approximately isotropic. Generally, high humidity will make the distribution anisotropic, AtmospherAr counter-emission in cloudy conditions is practically isotropic ind endently of the height of the cloud. Mean values of ~W for different values of w are given in Table 1. Using the data on the angular dis4ribution an card 4/6 estimate can be made of the diffusion of.the emission ond the integral absorption function. Kondratlev, K. Ya.

(Cont.) intensity. The value of this coefficient found by the present writers from a series of 173 series of measurements in diffeant conditions is 1.68 (w., between 0.41 and 2.66 g/cm ). This coefficient is independent of the general water vapour content. The angular distribution of tho intensity of the counter-emission can be used to determine the integral absorption function for an isothermal atmosphere and a directed radiation. Since In the real atmosphere the temperature decreases with height, it is necessary to reduce it to an isothermal one. This is in accordance with the procedure suggested by Brooks (3). The absorption functiob, for such a "reduced" atmosphere was determined from the experimental results (150 series of measurements of the intensity of counter-emission). Differences are observed between the value of A i obtained in different places and during different times of the year. The absorption function A, appears to depend on temperature and pressure. There are 5 figures, 2 tables and 4 references, 3 of which are Slavic. 49-5-16/3-8 SUBMITTED: October 12, 1956., q: Leningrad State University imeni A. A. Zhdanov. ASSOCIAT101 Zhdanova).

The calculations may also be based on the equation of energy balance in the volume. A solution of the problem has already been pub- lished by Boshnyakovich for the case of the admission of gas to a constant volume, and the present article considers the more general case of admission to a variable volume. The general equation of energy balance in a thermally Insu- lated volume to which gas is admitted is given by equation (1); this is suitably transformed and dimensionless oo- ordinates introduced to give equation (3). A number of particular cases are then considered and the appropriate formulae are given. The cases include a piston engine Card 1/2 whose indicator diagram is given, and one whose piston speed Some Special Features Variable Volume and gas flow by assuming it is shown There are 8 SOV/96-59-8-23/27 of the Process of Admission of.G,as to a rates are known. Finally, the errors introduced the process to be isothermal tire assessed and that in Some Cases they can be considerable. Soviet references.

PERIODICAL Yurn.teohn.fis, 26, fase.100 2154-2156 (1956) Issued: 11 / 19~56 The cast samples of HgSe and HgTe and their solid solutions weres as usualp pro- duced by melting the initial components in evacuated quartz ampules. Also the further treatment of the samples is described. These solid solutions aie charac- terized by a great mobility of their current carriers (up to 15-000 c'm /V.sec) and maximum mobility is attained by the solid solution with 50% HgSe and 50% HgTe. X-ray investigations of structure were carried out in the case of cast and powdery samples with DEBYE'S powder method, but in the case of film-like samples the grinding method was employed. The constants of the crystal structure measured are shown in a table. Conclusions: Annealing changes the constant of crystal structure in the HgSe-HgTe system only little, and the structure itself is left unchanged. The samples of HgSe and HgTe obtained by the simple mechanical mixing of components have the same crystal structure as the cast samples with the same composition. In the films of the HgSe-HgTe system a structure with the same parameters as in the cast samples is found, no matter whether they are transparent or not. Thus the films are distinguished in structure apparently only by the "size of grain". HgSe proved to be a very stable compound, Even at a sublimation temperature of Lrn.technJis,26, fasc.10, 2154-2156 (1956) CARD 2 / 2 PA - 1554 5000C sublimation takes place (if the lattice parameters of the obtained film and electric properties are taken as a basis) without any noticeable diasool- ation. HgTe -turned out to be lose stable than HgSe. Already at an evaporation temperature of 320 0 the parameters of the crystal lattice of the obtained film change noticeably. This is in agreement with the test results obtained by BRIDGMAN9 according to which HgTe is the only substance that is dissociated at a pressure of 15000 atm and at a temperature of 20 0 C. The films of the solid solutions, which contain a large quantity of HgTe, are thermally leas stable than the HgSe films. The films which are transparent in the optical spectral range have a crystalline but finely dispersive structure, which is confirmed by the data of electronographical analysis.

PERIODICAL: Zhurnal Toklinicheakoy Fiziki, 1957, Vol. 27, Nr 'I, PP-1595-1596 (USSR) ABSTRACT: Not monocrystals but thin semiconduotor-films of mercury selenide or mercury telluride were here used as sensitive transmitters of the Hall-EMK. The maGnetic permeability of the air was assumed equal to one. At first only one film was usedo as the authors assumed that below the center of the pole shoe the magnetic induction is proportional to the total magnetic flux. But as this is not accurate the attempt was mades for the purpose of obtaining exacter measurements, to perform an approximate integration of the magnetic flux according to one of the mathematical formula with the aid of several transmitters that were fixed along the pole and Card 1/2 connected with the battery. It is assumed that the error Oscillographic Measurement of the BlectromaEnotic 57-Zf_T_2T/40 Moment of a Direct-Current Motor With the Aid of Film Transmitters of the Hall-EMF of measuremont is not above 5 ~o.

TITLE some Special Features of the Electric Proportion of 11g3o- HgTo- Films. PERIODICAL turn.techn.fl-stalpfaso-1, 45-50 (1957) Issued: 2 / 1957 At first a survey of the present stage of the problem is given. Dealing with the entire system of solid solutions HgSe-HgTe, the authors dealt with the closest attention with the properties of NgSe films, because they have formed the subject bf the most intense study. The properties of the films of the entire system of the firm solutions HgSe - HgTe are essentially similar to the proper- ties of HgSe films. The electric conductivity and the EAT-1 effect of a group of transparent We films (thickness from 0,1 to 6 microns) were measured. The films were produced by evaporation (in a vacuum) on a base of quartz, glass, mica, farforp organic glass or getenacs (probably a material similar to farfor The material of these bases exercised but little influence on the properties of the films, and further glass and mica were mainly uEad as material for these bases. Electrodes of copper or silver were at first fixed on these base3, after which they were electrolytically coated with nickel or platinum. There follow some remarks concerning stability and reproducibility of results, as well as remarks on some peculiar features of the structure of the films. The following results were obtained from these investigations: The HgSe-HgTe films obtained by evaporation in a vacuum, in air and in steam differ only little with Yurn.teohn.fist1l.faso.1945-50 (1957) CARD 2 / 2 PA - 1949 respect to their properties. According to the temperature of the base and the forming velocity of the layer it is possible to obtain two basic types of Hg3e-HgTe filmst namely transparent and,untransparent films. In transparent films the dimensions of,orystallites are smaller than in untransparent ones, and also amorphous intermediary layers or a considerable deficiency of the crystals are possible. Untransparent-filma have characteristics which are simi- lar to those of cast samples. The concentration of the carriers in these films is usually lower by one order than in the case of cast (films ?), and mobility is from three to six times as low. The electric characteristics of transparent films are distinguished from the properties of untransparent films mainly by a deotease of the mobility of current carriers ty one order of magnituae, which is in agreement with the usual correlation between the structure and the mobility of the carriers. Transparent HgSe - HgTe films at the same time have consider- able conductivity, which may be of practical interest. It is possible to pro- duce untransparent films which are suited for measuring matrnetic field strength on the basis of the HALL effect.

The-data for the intermediate compositions in the HgSe-HgTe system provide values for the electric properties-that agree woll with the~properties of the system which forms a continuous aeries of solid solutions. The formation of sol-id solutions in the films was confirmed by an X-ray analysis. The mobility of the carriers in the films may be increased up to the values of the mobility in a mono- crystal. The value of the mobility does not depend on the thickness-of-the film and on the character of the scattering at.the boundary of the films (the Fuchs-Sondheimer (Puke - - Zondgeymar) theory-not being applicable in this case) but depends on the size and the degree of imperfection of the crystallites which constitute the sample.

The results obtained by tests are summarized as follows: 1) Oscillographing of the electromagnetic moment of a direct current motor according to the method of the Hall effect in semi-conductor films is possible on principle and gives sufficiently accurate practical results. 2)The semi-conductor transmitters of the Hall e.m.f. are inertialese and the inertia with oscillographing in determined exclusively by the vibrator-characteristics in the case of lacking of a polishing filter, 3) The transmitters of Hall's e*m9f.

This may be connected either with the occurrence of intercrystalline-interlayers offering increased resistance to recrystallization,,or a partial vaporization of the film during the annealing in vacuum. 5) The reduction of the imperfections in the crystallites constituting the film leads not only to a change of the electrical but also of the optical properties of the layers. 6) The synthetization of HgSe-HgTe layers exhibiting a mobility approximating the mobility of a cast sample permits to draw the conclusion that the production-of films of other semiconductors with characteristics similar to'the characteristics of the mono- crystals of the same substances is also quite possible.

The following theo- retical considerations viere. the premise for this generalization: It can be shown that the electromagnetic moment of a.c. machines is proportional to M - k(i I - iB1 ), where Me denotes the e A a A electromagnetic moment of the machine, k a proportionality fac- tor, iA and i B the instantaneous current values in the phase A Card 1/4 and B, respectively, and I A and I R the instantareous values of BOV/57-28-9-23/33 Oscillographing the Blectromagnetic Moment of Alternating Current Machines With Hall-EMF Battery Transmitters the magnetic fluxes in each phase which are generated by the phases A and B. In order to obtain the instaDtaneous values of the magnetic fluxes in each phase the 11all-kNIF film batteries were placed symmetrically at the inner stator surface in the (longitudinal) magnetic axes of the respective phases, The number of cells in the battery is determined by the require- ment to exclude the highest harmonies of the rotating magnetic field and is dependent upon the winding lay-out of the machine. In this investigation each battery consisted of three Hall-EMF transmitters. They were placed each at an angle of 60 electril: degrees. The middle transmitter was located immediately at-the phase axis. In order to exclude the first harmonic of the ~om- ponent of the rotating electromagnetic field such a current wa6 admitted by the middle transmitter of each battery as to raise the sensitivity of this transmitter (such a distribution of the sensitivities follows from the Fourier (Furlye) formula) to twice that of the side transmitters. If the transmitters are placed in such a way the instantaneous values of the projection of the vector I of the first harmonic of the rotating magnetic Card 2/4 field upon the corresponding axis are measured,that is to say so'V157-23-9-23/33 Oscillographing the Electromagnetic Moment of Alternating Current Kachi:_: With Hall-EhIF Battery Transmitters the instantaneous values of the flux coupled with the winding of the respective phase. These quantities are multiplied by~ the instantaneous values of the phuse currenta. When two transmitter outputs are counterbalanced the alternating com- ponents of the Hall-EMF cancel whereas the constant components add and provide signals proportional to the electromagnetic moment. It is necessary to use batteries vrith an equal overall sensitivity. At present a study is being made to reduce the noise to a minimum, and to design a filtQr with a, narrow resonance band.
