摘要
本文考察导热流体中等温间断的稳定性问题,给出了稳定间断的条件:p_1/p_0>r/(2-r),它比等温间断的产生条件(p_1/p_0>(r+1)/(3-r))要强。
In this paper the stability of isothermal discontinuity in a iluid is studied. It is shown that there may exist three kinds of steady shock waves: shock wave with smooth transition region unstable isothermal shock and stable isothermal shock. The conditions for the appearance of a stable isothermal shock are derivedaccording to the general principle. For ideal gases we obtaine:p1/p0>r/2-r.
