Then approximate analytic formula of system frequency are obtained. Meanwhile, approximate analytic formulation of limitvelocity is obtained.
而后求出了系统固有频率的近似解析公式,同时也得到了极限流速的近似解析公式。

In the range of incident velocities near to the perforation limitvelocity (V50), this mechanism depends on thickness and interlaminar shear strength of composite plate.
在接近穿孔极限速度的入射速度(V50)范围内,这一机制依赖于复合材料板的厚度和中间层剪切强度。

There are four emphases in -research, for instance, flow state in pipeline, distribution of concentration and velocity, deposition-limitvelocity and calculation of flow resistance or head loss.
