建立了连续波脉冲信号传输的几何模型、运动方程和连续性方程。给出了计算流体约束随时间变化时,管道中的压力和流体速度,给出适当的边界条件和初始条件,利用特征方法求解运动方程和连续性方程联立的偏微分方程,对连续波泥浆脉冲信号动态传输特性进行数值分析。

A kind of geomelric m.del on the pulse signal transmission is estal）lished, with motion equations anti continuity equations of pulse transmission. According to the geometric model, pipeline pressure and fluid velocity are calculated when fluid constraints change with time. Appropriate boundary condition and initial eanditian is set up, partial differential equations such as motion equations, continuity equations anti so on are solved by using the eharacteristie method, and the model of eontinous mud-wave pulse signal transmission system is numerically analyzed.
