下降或负垂直速度率
rate of descent or negative vertical speed
(它既不是指示空速,也不是真空速,而是速度的垂直分量。它由垂直速度指示器测量,或者更精确地说,由某一时段内的高度差来计算)

由于膨胀气体挤压这种物质、致使能量损失速度快、爆后产物的压力和温度迅速下降。这些损失作为膨胀波传到反应区之内、因而降低了压力和反应速率、且最终消除了对爆震波面传播的能量支持
As the expanding gases compress such material, energy is lost rapidly and pressure and temperature drop sharply in the reaction products. These losses are communicated to the interior of the reaction zone as a rarefaction wave, lowering the pressure and reaction rate, and ultimately removing support far the propagation of the detonation front
