The study also goes to the influence, upon stress waves, of the piles relaxation time, the equivalent viscous damping coefficient of soil around the pile and the unit rigidity of soil below the pile.

同时，分析了桩身驰豫时间、桩侧土的等效粘滞阻尼系数、桩底土的单位刚度等因素对应力波的影响。

To study the influence of rotary inertia on gear flowmeter natural frequency, keep damping and leakage coefficient as constant.

结果表明：与增大泄漏系数、阻尼系数相比，减小转动惯量可以明显的提高流量计的频率响应。

Then the damping effect of elastic restraint is verified and the influence of the damping coefficient and the spring stiffness on the damping effect is discussed.

验证了弹性约束对拉索振动的减振效果，讨论了阻尼系数和弹簧刚度对减振效果的影响；
