CaGa<Subscript>2</Subscript>Se<Subscript>4</Subscript>–GaSe system

The phase relations in the CaGa₂S₄–GaSe system have been studied using differential thermal analysis, X-ray diffraction, microstructural analysis, microhardness tests, and density measurements, and its T–x phase diagram has been mapped out. The CaGa₂S₄–GaSe system has been shown to be a pseudobinary join of the ternary system Ca–Ga–Se. The CaGa₂S₄–GaSe system has been found to contain limited solid solutions based on the constituent selenides. The electrical conductivity of CaGa₂S₄ has been measured and its current–light behavior and photoelectric properties have been studied.

Fluctuations in the rate of flow during filtration of polymer solutions

This article demonstrates the possibility of a loss of stability in steady-state regimes involved in the filtration of polymer solutions, and we present also the construction of a mathematical model on the basis of whose analysis we have ascertained the unique features of self-oscillations and stochastic oscillations which arise in the region of instability.Translated from Inzhenerno-Fizicheskii Zhurnal, Vol. 59, No. 2, pp. 211–215, August, 1990.
