英语翻译
Like the forehand and the backhand,the service precision is relative to its power:having 80% in power and 70% in precision will give you as much precision in your serve as having 50% in power and 40% in precision.

答案

唉我去了.这上面的翻译软件.
英语不咋地.凑和翻译下.
就像正手反手一样.发球的准确率是与力量有联系的.
80%的力量和70%的准度与50%的力量和40%的准度是一样的 （这个我也不大懂.大概意思应该是不要太在意力量而失去了准度.就像下网或者出界.)
