用法例句

The effect of Li_2O and B_2O_3 doping on the crystallization phase composition of mold fluxes bearing rare earth oxide was investigated by lithofacies and energy chart analysis in scanning electron microscopy.

通过在结晶器保护渣中添加Li2O和B2O3作助熔剂,在实验室内模拟渣膜的形成条件,结合岩相和扫描电镜能谱分析,研究了Li2O3和B2O3对含稀土氧化物保护渣结晶矿物组成的影响。

Influence of little Li_2O and B_2O_3 on the crystallization phases of mold fluxes containing rare earth oxide was investigated by the methods of lithofacies and SEM enrage chart analysis in this paper.

本文通过在保护渣中添加少量Li_2O和B_2O_3,结合岩相和扫描电镜能谱分析,研究了其对含稀土氧化物保护渣结晶矿物组成的影响,得到如下结论:(1)稀土氧化物可以促进保护渣中枪晶石析出,抑制玻璃相形成,增大保护渣析晶率;(2)当稀土氧化物含量达到一定数值,在保护渣结晶矿物中可以形成稀土硅酸钙相,稀土氧化物继续增加,会有未溶稀土氧化物固态质点出现;(3)保护渣中加入少量B_2O_3和Li_2O,可以促进硅灰石析出并抑制枪晶石形成,也可以有效抑制高熔点稀土硅酸钙形成,防止渣膜形成过程中过早析出高熔点物相。
