Yield Reduction Rate

Considering the natural infestation rate and thousand kernel weight reduction, the yield losses of the tested varieties ranged from zero to 10 56%.

综合考虑不同品种的自然受害率和受害后千粒重的下降，各品种的总体产量损失率在0 ~ 10 - 56 %。

The effect of loading rate, test temperature and pre-plastic deformation on hydrogen induced apparent yield stress reduction have been investigated.

研究了变形速度，试验温度以及预先塑性变形程度对氢致表观屈服强度下降的影响。

At the same time it is helpful to yield increasing, material consuming reduction, the reduction of the rate of defective products and the improving of operation rate of equipment.

它为生产车间的生产管理，设备运行监测提供了及时、准确的数据资料与依据，并且在提高产量，降低消耗，减少废品率，提高设备有效作业率等方面起到了积极的促进作用。
