Musicians wanting to push the envelope of conventional sound formed groups that prominently (and sometimes exclusively) featured the 'new wave' of synthetic sound.

音乐家们想让这个信封常规的声音形成的团体，突出(有时只)“新浪潮”合成的声音。

A new technique for picking the first S-Wave arrival is presented by multiplying energy ratio of the long window to the short window by the square of the amplitude envelope of waveforms in the paper.

提出了利用波形长短时窗能量比值与波形信号能量包络的平方乘积检测横波初至的新方法。

This method researches the echo envelope model which has been simplified in this paper under range wave and time excursion, and can compute the transmitting time more accurately.

该方法研究了幅度起伏和时间漂移条件下回波包络模型，并对模型进行了简化处理，可以更准确地计算超声波渡越时间。
