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.
