The buried pipe transfer equation, the frequency character and the attenuation equation of the leaksignal are studied.
研究了埋地管道泄漏信号波的传播方程，泄漏信号频率特性以及衰减方程。

Given that plans always leak, that's a signal to watch for; a sudden rise in German bond yields.
介于计划总是会提前泄露，我们需要留心这一危险信号：德国国债收益突然增加。

To solve the leak detection and location problem in pipeline flux, we built neural network model based on the difference of leak wave and normal signal.
