三峡电厂左岸机组在过速实验的关机过程中，当活动导叶开度约为4%，转速约为73rpm时，机组出现了强烈的异常振动现象。

A strong abnormal vibration happened during the over-speed test on the Three Gorges left bank hydropower station . When vibration occurs , the opening of the guide is about 4 % and the rotational speed is about 73 rpm .

导叶开度对水轮机的效率有一定的影响，在最优工况正背面压差最小，水力损失最小；偏离最优工况，压差和水力损失都会增加。

The guide vane opening could affect efficiency , the pressure difference between positive and back of guide vane is minimum in optimum operating condition , and also the hydraulic loss . And in any other conditions , the pressure difference and hydraulic loss will increase .

旗叶长、旗叶宽、旗叶面积、穗平均芒长均与穗粒重呈显著正相关；旗叶开张角、披垂度与穗粒重呈显著负相关。

The flag leaf length , width , area and mean awn length per spike were found to be significant positive correlation with grain weight per spike , the blade angle and bend degree of flag leaf to be significant negative correlation with grain weight per spike ;
