The composi tional change profiles of monazite demonstrate a heterogeneous distribution of e lements La, Ce, Nd, P, Th, Si, Ca and U. This was caused by the differences in geological environments, temperatures, pressures and compositions of the hy drothermal solutions.

根据微区剖面(0.18mm)元素分布曲线，指出了La、Ce、Nd、P、Th、Si、Ca和U等元素表现出8～10个微环带成分不均匀分布的特点，并认为成矿溶液的地质环境、温压和微量元素含量变化是不均匀分布的主要原因。

No transition state was found from mono-σ bonding state to 1,4-binding state by our theoretical calculation, so the adsorption mechanism of benzene on Si(111)-7 * 7 surface was proposed.

计算结果表明苯在Si(111)- 7 * 7表面的主要吸附种是双σ成键的1，4加成产物，不稳定的单吸附物种可能是 1，4加成物种的前驱态。

In this paper, the Al~(3+)-doped ZnO thin films were prepared on Na-Ca-Si glass substrateby Sol-Gel process from 2-methoxyethanol solution prepared by Zinc acetate as premonitory, monoethanolamine as stabilizator and aluminum chloride reaction.

本文采用溶胶-凝胶工艺在普通Na-Ca-Si玻璃基片上成功地制备出Al~(3+)掺杂型ZnO薄膜。

Italian cross-stitch an d Montenegrin stitch are reversible, meaning the work looks the same on both si d es.

意大利挑花和黑山十字绣是可逆的，也就是说，工作看起来双方的相同。

The lattice parameters in both solid solution at equilibrium andextended solid solution prepared by melt quenching seem to be predicted with moreaccuracy.By this modified model,the lattice parameters of Cu-Al,Cu-Si and Ni-Al systems solid solution at equilibrium and Ag-Sn,Ag-La and Ag-Gd extendedsolid solution were calculated.They are in better agreement with the experimentalvalues than the Moreen′s.

用本修正方法可以更准确地预测平衡固溶体和溶体淬火制备的扩展固溶体的品格常数，计算了Cu-Al，Cu-Si，Ni-Al平衡固溶体和Ag-Sn，Ag-La，Ag-Gd系扩展固溶体的晶格常数，本修正方法计算值比Moreen模型计算值与试验值相符更好。
