The research results show that the vibration times, initial static stress level and water content etc. have obvious influence on the dynamic intensity of fly ash;

研究结果表明：振次、初始静应力水平、含水量等对粉煤灰的动强度都有显著的影响；

Vibration times hardly have effect on the changing of the elastic strain in the condition of the dynamic stress.

在动应力条件下，振次几乎对动应变中的弹性应变的变化没有影响。

The effects of the times of loading and vibration frequency on isolator are studied…

分析了载荷作用次数及振动频率对隔振器性能的影响，提出了提高其寿命的方法。

For example, spreading the same number of journeys over a greater period of time through trading across may well bring the benefits of easing congestion at peak times, but roadside residents will not be grateful when traffic noise and vibration start earlier in the morning and continue through the night.
