采用三维非线性有限元法，对百色RCC重力坝 3B坝段进行破坏模式及稳定性的研究，确定出含陡坡建基面 3B坝段在超载法和综合法下的破坏模式及稳定安全系数。

Luminescence properties of basal plane dislocations in 4H-SiC are studied by means of cathodoluminescence and defect selective etching.

本文利用阴极荧光和选择性刻蚀的方法对4H-SiC同质外延材料中基面位错的发光特性进行了研究。

The arch dam is a structure with many redundant, and its base surface is a spatial curve with the complex shape usually .

拱坝是一个高度超静定的结构，其建基面一般为形状复杂的空间曲面。

The TEM observation of dislocation configuration shows that SiC whiskers can suppress the slip coplanarity in the Al-Li based alloys.

变形位错组态的TEM分析显示，SiC晶须对基体合金拉伸变形过程中由δ'相引起的共面滑移具有抑制作用。

In the normal group, electron microscopy showed normal chondrocytes were oval, and cells and cell membrane were intact. In cytoplasm, there were abundant rough endoplasmic reticulum, dictyosome, and mitochondria with intact nucleus, and even chromatin. In the model group, chondrocytes exhibited obvious pyknosis and their shape was irregular. The areolae around cells disappeared; cell organs in cytoplasm coagulated to flaps which showed electron dense and was uneasy to observe; the shape of nucleus showed irregularity, and caryotin gathered densely.
