1·It is found that there is a threshold energy density in laser doping, and distributions of dopant density and depth have relation to preheat temperature and plating layer thickness of the impurities.

激光掺杂存在一个阈值能量密度。掺杂浓度和深度的分布与预热温度和杂质镀层厚度有关。

2·Doping can excite a charge density wave weakening the spin density wave against the stability of the ferromagnetic state.

掺杂能激发电荷密度波，从而削弱了自旋密度波，最终不利于铁磁态的稳定。

3·The influence of Mg concentration in doping on phase matching temperature, phase matching Angle, optical homogeneity, lattice parameter and density of the crystal is also stated.

掺镁浓度对晶体相匹配温度、相匹配角、光学均匀性、点阵常数和密度的影响。

4·With the increase of molding pressure, holding pressure for certain time and adding a certain amount of boric acid doping, the compact density and saturation magnetization correspondingly increase.

随成型压力的增加，当保压一定时间、添加一定量助烧剂时，生坯密度随之增加，饱和磁化强度也相应提高。

5·The electronic bands, density of states and optical properties are obtained accordingly, and the doping-effects on the electrical and optical properties also are analysed.

分析讨论了晶体结构，电子能带，态密度和光学性质与掺杂元素种类和掺杂量之间的关系。
