摘　　要：从气液、固液、固气两相流的基本方程着手，利用特性曲线法对流体的流动瞬变推导出计算公式并不需对两相流作均匀分布的假设，经气液两相流的瞬变流的理论计算与实验验证，证明该方法是能满足工程精度要求的．From basic equations of gas liquid,solid liquid,solid-gas two phase flows,this paper uses characteristic method to develop the calculating formulae for two phase flow transients.A comparison is made between the calculated result and the measured one for gas liquid flow transients.It is verified that the method is satisfoctory for the engineering requirement.
