The results show that the particles character as the growth of anion coordination tetrahedron during solvent thermal treatment, where blende-type ZnS particle is in the shape of double cone or tetrahedron, blend-type CdS appears as the tetrahedron, but wurtzite-type CdS is in the shape of cone. In addition, the particles with the better crystallinity are obtained with the increase of solvent thermal treatment temperature and time.

结果表明：采用溶剂热处理，粉末形状呈现负离子配位多面体生长特征，闪锌矿型ZnS粉末由球形变为双锥状或四面体状，颗粒上有明显的电子衍射花纹；闪锌矿型CdS晶体粉末主要呈四面体形状，而纤锌矿型CdS晶体粉末则以锥状为主，并且粉末的晶型随溶剂热处理温度的升高和时间的延长更趋于完整。

The precipitation of alloy carbides was observed and analyzed by TEM and EDS.

用透射电镜和电子衍射分析了合金碳化物的析出。

Completely different crystal structures and morphology were shown in the meltdrawn films of two kinds of tacticity of sPP. A continuous conformational transform from the 〓 into the of sPP was induced by further stretching. While the zigzag conformation can retransform back to helical 〓 one after annealing above 80℃, the mechanism of conformation transform has been introduced.
