| 摘 要： | 文献〔1〕中采用laplace变换方法得到一个确定漏失位置的计算公式，经验算其计算结果是错误的。本文对管网中气体漏失过程的一般模型，采用laplace变换的渐近方法，推出确定管网中气体漏失位置和漏失流量的近似公式，方便适用，测量和计算简单，原则上对复杂管网内气体漏失问题也一样适用。

| Abstract: | In Reference(1), a calculation formula for gas leak position is obtained by using Laplace Transform，but its result is wrong by checking, In this paper,according to the general model, an approximate calculation formula for gas leak position and gas leak flow in pipeline networks is obtained by using asymptotic methods of Laplace Transform, This formula is simple in measurement and calculation, and is suitable for gas leak problems of complex pipeline networks. |
