The directyield and recovery rate of metallic In, Pb, Sn and Sb are respectively over 90% and 95%.
金属铟、铅、锡、锑的直收率达到90%以上，回收率达95%以上。

Yet in the selection for yield improvement, the practical effect of directyield selection in plant-to-row generation was not satisfactory.
在产量改进的选择中，株行世代直接选择的实际效果较差。

In most shell problems the moments and direct forces will not be of simultaneous importance so that yield relations between moment and force are of limited importance.
