结果显示,气流的改变主要受电弧瞬时功率控制,最大流量不是发生于压力峰值时刻而是出现在电流过零时。
It is found that the gas flow is mainly controlled by instantaneous arc power and the maximum of gas flow appears not at peak pressure, but at current zero.
MG V装置降低蜗壳进口压力最大峰值的作用。
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.
