1) impurity productivity
杂质产生率
1.
The impurity productivity in the melt of binary compound A_mB_n,as well as the concentration of the surplus composition impurity in the melt and crystal has been studied in this paper with the viewpoint that composition volatility produces impurity.
本文从熔体组分挥发产生杂质这一观点出发，研究了二元化合物Ａ＿ｍ＿Ｂｎ熔体中的杂质产生率以及过剩组分杂质在熔体和晶体中的浓度，并导出了浓度分布的数学表达式，分析了组分挥发对熔体提拉法晶体生长的影响，并对其结果进行了讨论。
2) productivity-quality
质量-生产率
1.
