【 摘 要 】

The peculiarities of the transient processes in separation of isotope mixtures with various numbers of components are considered. A model Q-cascade without its depletion part is taken as an object of the research. It is shown that before entering the stationary mode of operation in the cascade the concentrations of the intermediate multicomponent mixture components in the product flow demonstrate the nonmonotonic behavior when they pass through the maximum and the minimum before the subsequent achievement of their steady- state values. It is revealed during calculations that the "abnormal" behavior of the end concentrations is primarily caused by the initial composition of a separated mixture.
