After heated to the softening point, the flat glass receives a rapid and even cooling treatment on its surface, with the compression stress in outer part and tension stress inner part.

钢化玻璃是将平板玻璃加热到接近软化点时，在玻璃表面进行均匀的急速冷却，使玻璃表面产生压应力，内部为张应力，从而提高了玻璃的强度和热稳定性。

In this thesis, We Study the degradation of Ultra-thin gate Oxide under FN stress and Hot-carrier stress.

This kind of damage is called Foreign object damage or simply, FOD. The main form of foreign object damage are notch, avulsion, disjunction and indentation in local regions where produce stress concentration, residual stress , shear bands as well as .

这种外物冲击损伤(Foreign object damage，简称FOD)主要表现为叶片局部区域出现缺口、撕裂、折断和凹坑等，并在局部产生应力集中、残余应力及剪切带、初始裂纹等，给撞击后的叶片寿命带来严重影响。

The effects of temperature gradient on the forgeability of heavy forging were analyzed.

结果表明，锻件的温度梯度对其应力应变具有重要影响，温度梯度越大，锻件中心的等效应变和静水压应力越大，压实中心缺陷的效果越好。

This report involves our research works in the fields of coseismic earthquake stress triggering, fault activities, free oscillation of the earth, precursory changes prior to earthquakes and earthquake forecast.
