在炸药爆炸过程中、合成能量转化为破岩和位移这些有益的实用能量。振动、冲击波和飞石这些不利的负面效应也是由合成能量产生的
In the detonation of explosives, the resultant energy is converted into beneficial applications such as fragmentation and displacement. It is also responsible for adverse side effects such as vibration, airblast and flyrock
在爆破设计时选择最佳单位炸药消耗量,既能消除经济成本方面的顾虑,又能消除环境方面的顾虑
An optimum powder factor can satisfy both economic and environmental considerations in blast design

爆速和爆震正面压力基本上是由在爆震正面立即产生反应的炸药的初始部分释放的能量决定的
The detonation velocity and detonation front pressure are essentially determined by the amount of energy released by the initial fraction of the ingredients that react immediately at the detonation front
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

评估空气振动能级受气象效应影响的程度、需要测量或评定地面的以及地面上空的温度、风速和风向
An of the degree to which air vibration levels will be affected by the effects of meteorology requires that temperature, wind speed and wind direction be measured or evaluated both at the surface and at levels above the ground
