Polar polymers should have lower values of the linear expansion coefficients than non-volar polymers. This was found to be the case for polychlorosty-rene, in which the temperature coefficient of linear eFpansion between 20 and 1000C was found to lie between 58 0 and 66.0 x 10-6, .7 x 10 while for polystyrene in the range 20 to 850C,_ lie temperature - coefficient was found to lie between 74.4 x 10 @ and 75.4 x 10 For polymonochlorostyrene this rule doeq not hold, beginning at approximately 550C. The temperature coefficient of polymono- chlorostyr ne in the tempegature range 20 to 1000C lies between 67.5 x 10 9 and 91.6 x 10- . It is suggested that the thermal expansion of polymers is affected not only by polar groups but also by other factors, such as the length and flexibility of the matn and side chains. The relative expansions of crystalline polymrrs also showed hysteretic behaviour both in the relative expansion and the expansion coefficient. A characteristic property of crystalline polymers is the fact that the expansion coefficient Card 3/4 866 0@ s/no/61/o /001/002/023 E032/E455 Thermal Expansion of Polymers returns to its original value after about ten hours.

SibirBk. fiz.-tekhn. in-ta, 1958, Nr 36, pp 361 - 363 ABSTRACT: The steady existence of the residual electronic concentration in the nightly F2-layer makes one to pay attention to possible sources of a supplementary Ionization (SI) in the F2-layer. In order to sustain the nightly concentration level of electrons, a rate of ion generation of the order of 0.1 pairs/cm3.sec is required, The UV-radiation of stars and the primary cosmic radiation are considered as the possible sources of the SI. The flux of stellar photon energy turns out to be at least 10,000 times weaker than the required quantity. The primary cosmic radia- tion can generate only 10-7 ion pairs per second, The author proposes the thesis according to which the SI is generated by Card 1/2 the electrons emerging from the P -decay of neutrons entering 835-7 G SOV/169-59-7-7471 The Neutron Decay and the Residual Concentration of Electrons in the F2- Layer of the Ionosphere the F-region of the ionosphere from the troposphere, where the latter are generated by nuclear reactions due to cosmic rays. These electrons move in the magnetic field of the earth along the helices. The electrons having an energy of about 0.5 Mev can generate along their path 1.15 pairs of ions per second. The quantity of these electrons can turn out to be sufficient for sustaining the minimum level of the residual electronic concentration. The data on the correlation of intensity of the neutron component of the cosmic radiation in the troposphere with the ionization level of the nightly F2- layer can be used for the verification of this hypothesis.

Estimates showed that with a neutron concentration of the order I cm-3 the A -electrons produced by neutron decay (which have an average energy of 0.5 MeV) are captured by the terrestrial magnetic field. They move on screw-shaped paths having a radius of up to 70 m and are able to produce up to 1.5.104 secondary electrons per primary O-electron. In the case of n5utron concentrations of 1 cm-3 and a half-life of 270 600t 10- primary_qlectrons Card 1/4 (with an energy of 0-5 Mev) can be produced per cm 3. 7 _7 6n the' Possible Methods of Measuring the SOV120-123-1-14156 Concentration of Slow Neutruna in the Layer F2 of the Ionosphere The lowest intensity limit of this ionization caused by the R -decay of neutrons in the F 2 layer is of the order of 0.1 pairs om-3. see* -1 per I neutron in 1 cm3. The existence of an ionization source of this intensity must make a measurable contribution towards ionization of the F 2layer if the most important ionizing factor, the solar photon radiation, is lacking (nocturnal sky). The equilibrium value of the electron concentration corresponding to the ionization intensity 0.1 em'.3.sec-1 amounts to 2.2.104 electrons in 1 em3. To this concentration there corresponds the critical frequency of 1-3 megacycles. The lowest values (averaged for one month) of the nocturnal minimum of the critical frequencies of the F2 layer (for an ordinary beam) were observed in January 1943; they did not decrease below the value of 2.0 megacycles. These values were measured at Tomsk. The values of the nocturnal minimum fo measured in individual nights of January 1943 Card 2/4 F2 R_ On the Possible Methods of Measuring the SOV/20-123-1-14/56 Concentration of Slow Neutrons in the Layer F2 of the Ionosphere amounted to 0.9 megacycles. If the ionosphere is considered to be an ionization chamber in which electron concentration is measured by means of radiophysical methods, it may be said that the obAerved remanent nocturnal ionization indicates the existence of a hitherto unknown ionization source. If P-decay is considered to be the source of this ionization, this assumption must be verified by immediate measurement of neutron concentration by employing the direct methods of detection and by counting the slow neutrons. A short report is given on such measurements carried out by various authors. Various considerations indicate the possibility of measuring neutron concentrations of up to jo-7 om-3 by means of unahielded counters with BF3f which are conveyed into the upper atmosphere. It is of great importance for the investigation of the dynamics of the neutron component of the terrestrial atmosphere and its possible influence on the remanent ionization of the ionosphere to obtain immediate data concerning neutron concentration in Card 3/4 the upper atmosphere.

Sibirsk. fiz.-tekhn. in-ta pri Tomskom un-te, 1959, No. 37, PP. 10-15 TM; The author gives a concise summary of the works on the propagation of radiowaves and the physics of the ionosphere, which were published by 1956. It is stated that the ambiguity of the deciphering of ionograms and the absence of reliable data on the molecular and atomic compcsition of the ionophere lead to the necessity of rocket sounding of the ionosphere. The reception of signals emitted from the moving rocket and coordinated in frequency as well the investi- gations by the method of injection of extraneous gas masses are of special Impor- tance.- It is noted that the rocket research complements essentially radiophysical methods, but the development and the improvement of the latter remains the priority problem in the study of the upper atmosphere. The special actuality of the works is emphasized in connection with the study of the scattering of the pulse signals Card 1/3 89078 s/169/61/boo/boi/oWbii A005/AO01 Propagation of Radiowaves and the Physics of the Ionosphere in the ionosphere, the scattering by the meteor trails, and the phenomena caused by the diffraction of the signals by inhomogeneities of the ionosphere, which are statistically distributed, changing with time, and moving in space. It is noted that the problem of the nature of reflections with the,apparent value of reflection coefficient R > 1 occupies a peculiar place among the problems of the methods of:bnospheric observations. The investigations of idealized ways of propagation in the ionospherb and of the peculiarities of propagation in a gyro- tropic medium occupy a large place In the group of the theoretical works. The graphical and graphoanalytical methods of Investigation of the course of rays in the ionosphere are applied successfully. The works published showed that the events of triple splitting of reflected signals are correlated with large values of the gradient of electronic concentration in-the F2-region near the maximum of the layer. The possibility of the stable existence of large gradients of electronic density in the ionosphere becomes obvious when considering the abi- polar diffusion with allowance for the effect of the geomagnetic field. Valuable results are mentioned from the investigation of the diffusion in the ionosphere which were obtained by V. M. Polyakov (Irkutsk). It is shown that the development Card 2/3 89078 s/169/6i/ooo/ooi/oo6/oii A0051AOOI Propagation of Radiowaves and the Physics of the Ionosphere of the theory of magnetohydrodynamical phenomena in plasma led to the substantia- tion of the hypothesis on the stable existence of Inhomogeneities of plasma in the Ionosphere. The small quantity of scientific data on the problem of the effact of the troposphere on the,propegation of short waves is pointed out. There are 31 references. E.

The condition of tho appearance of a secondary field wi.-th a stationary or a slowly-changing complex amplitude i-q analysed for the case when ui lij; e w .< .1. and / w '
