dimensionless constant

CASE damping constant Jc is an important dimensionless experienced constant during high strain dynamic pile testing.

CASE阻尼系数（Jc）是CASE法高应变动力试桩中一个重要的无量纲经验系数。

The numerical results show that mass ratio, dimensionless relaxation coefficient and dimensionless elastic constant ratio all have influence on the dynamic characteristics and stability of the viscoelastic pipe conveying fluid.

计算结果表明，质量比、无量纲松弛系数及无量纲弹性常数比对输流管道的动力特性均有影响。

On the other side, the time of gas breakthrough decreases, the oxygen content of the breakthrough gas decreases and the displacement efficiency at gas breakthrough increases with the increase of the temperature when the dimensionless pressure is constant.

无因次压力一定时，随着温度的升高，气体突破时间缩短，突破气体含氧量降低，气体突破时驱油效率增加。
