The influences of the two methods of MM and SI on the microstructure and the electrical properties were investigated by scanning electron microscopy and conductivity measurement. The results show that EG is easier to exfoliate into nanosheets using SI method than MM method, thus the latter have more outstanding conductibility.

运用电导率测试、SEM研究了MI和SI两种制备方法对复合材料的导电性能和形态结构的影响，发现插层作用和超声作用使得SI法较MI法更容易使EG剥离为纳米级厚度的石墨片，所以具有更佳的导电性能。

The sulphur atom in the intermediate has sp2 hybridization, and the remaining p orbital is symmetrical to the d orbital of the metal center. Thus, the lone pair on the p orbital can have interaction with the d orbital to form a π bond, which leads to the coplanarity of the center of Cp ring, Ru, P, S and Si atoms, rather than the deviation of P, S and Si atoms from the plane.

该中间体中，硫原子采取sp2杂化，硫原子剩余的一个p轨道与金属中心上的d轨道具有相同的对称性，因而该p轨道上的孤电子对可与金属中心上的d轨道形成π键，导致Cp环中心， Ru， S1， P和Si原子在同一平面内，而不是S1， P和Si原子偏离该平面。

Results In the course of interaction between organism protein and crocidolite, the protein symmetry decreased and structure loosened. The silicon of crocidolite was bonded with the alkyl, amido- of protein. New absorption bands of Si-O-C, Si-R clearly appeared.

结果 机体蛋白质在与青石棉的相互作用过程中，组织结构对称性降低；青石棉的矽已与蛋白质中的烷基、胺基交联成键，存在明显的Si-O-C、Si-R新的吸收谱带。

Between the {111} planes in single crystal Si there are two interplanar spacings, d(111) and d(111), but there is only one interplanar spacing d(110) between Si {110} planes, so that their blocking dips would be different.

单晶Si的{111}晶面有两个面间距d_(111)~和d_(111)~，而{110}晶面只有一个面间距d(110)。由此导致两者的堵塞坑是不同的，我们已从α粒子和质子的Si单晶堵塞效应的实验得到了证实。

We also studied a role of Si DBs in defect PL in Er doped a-Si:H.

本文还研究了Si DBs在Er掺杂a-Si：H的缺陷PL中的作用。

The EL excitation process was attributed to hot electron impact ionization of Si QDs by the dependence of the EL spectra on the change of the energy distribution of hot electrons.(3) Efficient green-blue ACTFEL was first obtained from Si QDs in Si layers of Si/SiO〓 superlattices.

利用磁控反应溅射方法制备出含硅量子点的富Si-SiO〓薄膜，通过热退火并结合喇曼光谱和光致发光谱判定了其中硅量子点的存在和平均尺寸，将发光机理归结为硅量子点中的量子尺寸效应。

The crystalline defects of metallic substrate can promote the formation of multi-crystal thin films. In contrast, the films on the Si single crystal are basically amorphous; The hardness of films are mainly determined by N concentration. The highest hardnesses of Si〓N〓 and TiN films ware obtained at 1. 1 of N/Si and 0.96 of N/Ti respectively. The hardness of Si〓N〓 film decreased dramatically when the free silicon atoms present.

发现薄膜中N原子百分含量主要受氮离子束流和氮气分压的控制，随着氮离子束流和氮气分压的提高，N/Si和N/Ti原子比增加；膜的组织结构则主要受轰击离子束压和基体种类的影响，高的轰击束压可以抑制薄膜的择优取向，金属基体上的晶体缺陷使薄膜易于形成多晶，而单晶硅上的薄膜基本上为非晶态；薄膜的硬度受氮含量的影响最大。
