PdBi2-PdPb2 and PdBi-PdPb sections were investigated by X-ray, micro3copic, and thermographic methods. It was established that triple solid solutions are formed on the basis of the compounds PdBi2, PdPb2, and PdBi with partial substitution of bismuth or lead atoms. The change in the periods of the elementary cells and in the minimum interatomic distances when the composition of the triple solid solutions is changed is determined.

The space-time correlations of the velocity in a chute over a rough bottom are measured. The time Lagrangian scale is determined from the envelope of the maxima of R ( X1,0,0,t). The values of the mixing path are found from the Prandtl formula and from the value of the Lagrangian time scale.

Experimental data are presented on the action of α-particles on p - silicon and silicon n-p junctions in the energy range from 0.4 to 25.2 MeV. A comparison is also made with proton action.

A laboratory investigation of the momentum flux in the upper layer of water when regular monochromatic waves of considerable slope propagate is described. The distributions of the total and purely turbulent momentum fluxes with depth are obtained. The numerical values of the total momentum fluxes in the upper levels are approximately an order of magnitude greater than the momentum fluxes found from the pulsations of the vertical and horizontal velocity components.

The spectral - angular characteristics of spontaneous and stimulated emission when electrons move in a medium in a wave field are obtained. The stimulated emission is investigated as a function of the wave intensity and also as a function of the refractive index of the medium.

The operation of a balanced parametron circuit when there is a mutual inductance M present between the tuned circuits, and also taking into account the effect of the resistance of the automatic bias circuit Rp and the resistance of the parametric generator in the forward direction Ri is investigated.

A method of obtaining wide regions of stable submultiple synchronization by means of a transition to synchronization at the fundamental frequency is des cribed. The steady processes are investigated for the case when it is necessary to obtain at the output of the system a signal which is in one of three close submultiple ratios with respect to the input signal. The experiments show good qualitative agreement between the spectrum obtained and the spectrum calculated on a computer. The small quantitative disagreement is explained within the framework of the approximate theory.

The quantitative basis of a method of increasing the spatial resolution of a cathodoluminescent image in a scanning electron microscope using a three-dimens ional model is presented. An improvement in resolution by a factor of five is obtained in specimens of CdS and ZnSe semiconductors.

The conditions for multifrequency oscillations to be stable are obtained using the harmonic balance method. It is shown that for the periodic process to be stable it is necessary to synchronize a minimum of three modes. Nonperiodic processes are also considered.

The temperature dependence of the bulk modulus of solids is obtained which is in good agreement with experiment.

The region in which a high-current pinched discharge with reverse current can exist in optically nontransparent and optically "gray" (semitransparent) plasma is analyzed and a relation is obtained between the fundamental parameters of the plasma and the external parameters—the total number of particles in the discharge and the discharge current strength. Using the relations obtained a quantitative analysis is made which applies to typical experimental conditions.

The effect of annealing at 250°C for fifty hours on the optical properties of quartz irradiated with an integral flux of fast neutrons of 4*10^18 n/cm^2 is investigated. It is shown that prolonged heating does not lead to complete annealing of the radiation defects including color centers. The existence of incomplete jannealing is indicated by the anomalous temperature behavior of the intensity of the 128 cm^(-1) and 466 cm^(-1)lines in the Raman spectrum of the irradiated specimen, I and also by the fact that the maximum at 2.78 μ is still present in the infrared spectrum after annealing.
