摘要：

A simple model equation that takes into account the nonisentropicity of the flow is obtained from the equations of a viscous heat-conducting gas. This equation is suuitable for one-dimensional traveling waves on the Mach number interval 1 &le M &le 1.3. The equation obtained gives the asymptotic law of damping of weak shock waves correct to small terms of the leading and next order for plane, cylindrical, and spherical symmetry.
