微波辐射功率提高，木材内部蒸汽压力上升速度相应加快，压力峰值也相应变大，最大压力值保持的时间变短。
If the power of microwave radiation increases, the steam pressure increases quickly in wood, its peak value becomes higher and the holding time of maximal pressure becomes shorter.
利用它对国产OFPI—220型SF_6断路器进行的计算结果表明，改变动触头排气孔位置及电弧对动触头内腔中气体的热效应可明显提高开断电流时灭弧室压力上升速度。
The results show that the position of the exhausting gas hole and the arc heat effects on the gas inside the hollow moving contact have obviously raised the pressure rising speed.
越靠近自由表面，底部射流横向发展越窄，而向上的压力梯度，气泡上升速度，底部射流上升高度越大，反之则反；
The more the bubble close to the free surface, the narrower the bottom jet develops crosswise, and the larger the pressure gradient, the rising velocity and the height of the bottom jet is upwards.
