This paper firstly presents two criteria: residual noise energy and signal distortion criterion to evaluate the degrees of noise suppression and signal distortion.
本文首先提出了客观评价噪声压缩效果的两个指标：残余噪声能量和信号畸变指标。

And to compensate the enhanced signal's energy loss and spectrum distortion, several reasonable schemes of Speech compensation are touched upon in the paper.
以补偿增强后信号的能量损失和频谱失真为目的，浅谈了几种语音补偿可实现的算法及设想。

Aseismatic performance of frame structure intensively depends on it's energy absorbency and nonlinear distortion capability, and realization of these capability is based on the damage of structures.
