1·At the same time, the shear strength contributed from matrix suction was analyzed, and the differences between the linear failure envelope with the nonlinear failure envelope were compared.

同时针对吸力对非饱和土强度的贡献进行了分析，利用试验成果对强度包线的线性和非线性进行了比较。

2·For cantilevered anti-slide pile, displacement of pile increase continuously with time, the topper displacement is max. The failure envelope is nearby design failure surface when load achieve extreme.

对悬臂式抗滑桩，桩身位移随时间的延长不断增大，桩顶位移最大，加载至桩破坏时，其破坏面在拟滑面附近；

3·The liquefaction front, originating from the envelope of initial effective stress points, gradually approaches the failure line as the cyclic mobility proceeds as a function of plastic shear work.

液化面作为累积剪切功的函数，从初始应力点的包络线开始，随着循环活动性的进行，逐渐接近破坏线。

4·At first the cepstrum envelope model is described. Then the vibration spectra of the normal pump and the pump with a bearing failure are compared in frequency domain and in cepstrum envelope domain.

文中详细给出了倒谱包络的模型，然后在频域和倒频域比较正常泵和轴承故障泵的功率谱变化及倒谱包络变化。

5·The cepstrum envelope analysis is applied to solve the problem of the diagnosis of bearing failure to hydraulic pump.
