In addition,the spectra and the g factor of GaP∶Co2+ crystal also are analyzed,the results show that,for the strongly covalent of GaP∶Co2+ crystal,it is not reasonable to neglect the covalency and the contribution due to the s.o.coupling of the ligand ion.

本文结果表明，由于GaP∶Co2+晶体共价性很强，再忽略共价性及配体旋轨耦合的贡献是不合理的。

Adding transition metals into the TiN films by arc ion plating (1) The hardnesses of theN films are higher that that of the TiN films, proving that the alloy hardening effect is a common phenomenon;(2) The structures of the alloyed films are determined by the added element properties such as covalent radius, electro negativity, free energy and lattice parameters of the MN compound;(3) theN film consists of a mixture of multi phases with high hardness but quite brittle, while the other MN films are composed of single phase with the fcc TiN structure and their hardesses, functions of the added amounts of the elements, manifest always a maximum at a certain M percentage.

一、将过渡金属M用电弧离子镀方法添加于TiN薄膜中：1。N薄膜硬度均高于TiN薄膜硬度，合金强化效应普遍存在；2。薄膜相结构决定于添加元素M的周期律信息，包括M的共价半径、电负性，及MN化合物的自由能、晶格常数等；3。N为多相混合结构，薄膜硬度高，但韧性差；其它N的相结构为TiN类型的单一fcc结构，薄膜硬度随M添加量变化并出现峰值；4。

Results of non-reducing sodium dodecyl sulphate polyacrylamide gel electrophoresis of the supernatant and aggregate precipitate formed in refolding process show that except being refolded to native egg white lysozymes, the reduced-denatured lysozymes can also form the aggregates with molecular weights being separately about 30.0 and 35.0 kD, while the reducing SDS-PAGE and the refolding results in the presence of sodium dodecyl sulphate show that these aggregates are formed chiefly through the misconnection of disulfide bonds between the reduced-denatured lysozymes, and the aggregate precipitates are formed through the non-covalent interactions between the aggregates with molecular weight being about 30.0 kD.

复性过程形成的上清和集聚体沉淀的非还原电泳结果表明，除了能复性成天然态的溶菌酶分子外，还原变性蛋白溶菌酶同时还能形成分子量分别约为30.0KD和35.0KD的蛋白溶菌酶分子集聚体；而它们的还原电泳和在SDS存在时的复性结果表明，这些集聚体主要是通过还原变性蛋白溶菌酶分子间的二硫键错配而形成，而集聚体沉淀则是通过分子量约为30.0KD的集聚体分子之间的非共价相互作用而形成。
