摘要
建立了气穴瞬变流基本方程，并重点讨论了下述三种情况的基本方程的特征根问题：ａ．ｐ－ｐｉ≠０且计入附加质量力；ｂ．ｐ－ｐｉ＝０且计入附加质量力；ｃ．ｐ－ｐｉ＝０且不计入附加质量力．
The basic equations for the transient two phase cavitation flow are formulated and three conditions of the characteristic roots of the basic equations are discussed, namely, a. p-p i≠0 and with the virtual mass force taken into account; b. p-p i=0 adn with the virtual mass force taken into account; c. p-p i=0 , without taking account of the virtual mass force. The study and calculation demonstrate that when more factors such as p-p i ≠0 and the virtual mass force are given consideration, there will be less possibility that the characteristic roots will be complex ones. Not only the properties of the basic equations but also the stable difference format of the solutions of the equations can be found provided the characteristic roots are determined.
