But when surcharge preloaded, the coefficient will change with the overloadratio and its duration time.
而当超载预压处理后,次固结系数随超载比和超载作用时间不同而变化。
2
After the overload cycles exceed a certain number of cycles, -the overload fatigue life ratio would be decreased with the increase of overload cycles.
当超载周数超过一定值时,超载寿命比随超载周数的增加而略有减少。

The cause of occurrence of power overload and the unstable curve of head-flow volume for low rate ratio pumps was analyzed in this paper. Some methods, then, were presented to solve the problems.
