Georges Cuvier had looked at fossils in rock strata and observed how the ones that lay deeper looked less like familiar animals. But Etienne St. Hilaire observed that all living animals had similar organs and anatomies. To Jean-Baptiste Lamarck this meant that, over time, all animals were changing their form.

乔治·居维叶通过观察岩石层中的化石发现：岩层越深，化石与相类动物的共性就越少；然而艾奇恩那·圣伊莱尔却发现，所有活着的动物都有着相似的器官和身体结构；在让·巴蒂斯特·拉马克看来，这意味着所有动物都随着时间的推移改变着它们的形态。

This paper presents the expressions of energy consumption in two types of blank holding: the conventional hydraulic cushion and cushion-compensating cylinder in single-action deep-drawing hydraulic press,and shows through comparison that the energy consumption in the latter one is far less than that in the former one.

用能量法推导了单动拉深液压机的两种压边方式即传统液压垫压边方式和液压垫—补偿缸压边方式的能量损耗表达式，以此为基础对两种压边方式产生的能量损失进行比较，结果表明后者远小于前者。

The feature of typical multiple rotational loess landslides is: large scale, deep sliding face, three-five sliding face cascades, single landslide with the "plough" structural character of behind high and sheer-middle subdued-front tilt. The main formation mode of landslide is creeping-sliding-tensile fracturing. The failure modes contain extensive rotation sliding, digressive rotation sliding and compound rotation sliding.
