关于具有集中的气体输出的输气管道中不稳定流动方程的基本解

本文借助于基本解的概念，对具有集中气体输出的输气管道中的不稳定流动方程，给出了三种定解问题的基本解，然后构造出三类复杂问题解的一般表达式。这个方法，还可应用于一些更复杂、更一般的问题。同时，我们还修正了参考文献(1〕中一些计算错误。

ON FUNDAMENTAL SOLUTION OF UNSTEADY FLOW EQUATION FOR THE GAS PIPELINE WITH CONCENTRATED GAS OUTPUT

With the help of the conception of fundamental solutions，this papergives three kinds of fundamental solutions of unsteady flow equationfor the gas pipeline with concentrated gas output，and constructs thegeneral expressions of three kinds of complex problems, This method is easy and the computational algorithms are simple.It can be applied to some more complex and general problems.Meantime,we have also corrected some errors in reference literature(1).
