limiting breaking velocity 限界破坏速度
limit breaking velocity 极限断裂速度
Based on experimental analysis and theoretical calculation, the wave velocity field has been obtained, which is used to calculate the wave height after breaking by VOF (Volume of Fluid) method.
首先通过实验测量和理论计算得到波浪崩破时的速度场，然后根据该速度场利用VOF法计算波浪破碎后的波高值；
For breaking wave the horizontal particle velocity can be taken as the wave celerity, since the wave is breaking when horizontal particle velocity is equal to or larger than the wave celerity.
而对于破波，质点的水平速度应该等与波速，由于破波产生的极限就是质点的水平速度等于或大于波速。
The results showed that with the the increase of outside force velocity, the tension yield strength of PVC increased, but its breaking elongation decreased.
结果表明：PVC的拉伸屈服强度随外力作用速度的提高而提高，断裂伸长率却随之下降。
