Sharapova's racquet is back a little higher than I was taught to take mine — my backswing was more compact — but it helps her produce greater racquet-head speed, which means more power.
莎拉波娃的球拍收回的时候比我做的高了一点- - -我的回拍更加紧凑- - -但是她的回拍使拍头速度更快，也就意味着力量更大。
In the process conditions permit, the change in pump flow, head, speed and medium operating temperature operating parameters, to avoid the occurrence of cavitation.
在工艺条件允许的情况下，改变泵的流量、扬程、转速及介质的操作温度等操作参数，可以避免汽蚀的发生。
