The crosscorrelation technology was used to measure solidvelocity.
采用互相关技术测量固体的流速。

The model includes solidvelocity, space grade of saturation with vapour density and space grade of porous pressure in concrete multiphase system.
考虑了混凝土多相系统中固体速度、饱和度乘蒸汽密度的空间梯度和孔隙压力空间梯度；

By the time he passed four thousand feet he had reached terminal velocity, the wind was a solid beating wall of sound against which he could move no faster.
