摘要
研究了二维粘滞性粒子动力学中的非自相似初值问题.该初值被一圆环分为内外两块常状态.利用广义特征分析的方法和广义Rankine-Hugoniot关系,该关系是常微分方程组,一个包含狄拉克激波和真空的整体解被构造性地得到.
Two dimensional non-selfsimilar initial value problem for adhesion panicle dynamics with two pieces corn.Croat states separated by a circular is considered. By using the generalized characteristic methaod and the generalized Rankine-Hugoniot relation which is a system of ordinary equations, unique solution which indudes delta-shock waves and vacutma is constructed.
