No direct fluid wave exists.

无流体直达波。

Shifting dullness and a fluid wave are more difficult to elicit and require more ascites.

移动性浊音和流体波更难引出而且需要更大量的腹水。

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；
