The overall yeild of the reaction reaches 86.5%.

确定了较满意的反应条件，反应收率达86.5%。

In this paper, authors evaluate the coal washability using the petrological method of clean coal yeild and coal density consist in Wuda coalfield.

以乌达矿区为例，用精煤的产率和煤样密度组成的煤岩学方法对煤的可选性进行了评价。

Mean value of K for the basin, being considered together with pattern of runoff yeild, to be chosen-optimized as a parameter for the runoff yield model.

数域面平均K值应与数域产流模型结合考虑，作为模型参数优选确定。
