Method of the characteristics for calculation of currents of one-speed heterogeneous mixtures in Lagrange variables

The description is represented of a method of the characteristics intended for integration quasihyperbolic equations (with the multiple radicals of secular equations), decribing currents of one-speed heterogeneous mixtures in Lagrange mass variables. The designed formulas of a method are introduced for binary mixture consisting of contracted fractions, and also outcomes of test calculations are presented.
