地层振动合成速度如果地层振动速度已在三个相互垂直方向加以测定，则可用矢量代数求出合振动的大小和方向，单位为 mm/sresultant ground vibration velocity
地震加速度地震时地表岩土质点单位时间内的位移速度,单位以 cm/s² 表示earthquake acceleration
地震波的传播速度纵波 〈Cₚ〉和剪切波〈Cₛ〉由震源向外传播的速度，单位为 m/spropagation velocity of seismic waves
大气温度的增高、促使声速增加、这是说在这些条件下、大气折射可将冲击波挡回到地面An increase in air temperature causes an increase in the speed of sound, which means that in these conditions airblast emissions can be focused back toward the ground by atmospheric refraction
最大诱发地面振动速度爆破诱发的地面最大振动速度,单位为 mm/smaximum resultant ground vibration velocity
用质点振速表示爆破地震效应强度的原因1. 质点振动速度不受覆盖层类型及其厚度的影响。 2. 可适用于不同的测量仪器、不同的测量方法和不同的爆破条件。(3)结构的破坏与质点振动速度的相关关系比位移或加速度更为密切reason for using particle vibrating velocity to illustrate blasting vibration intensity
经过多次实地测试、他们的结论是、如果药量的增加、破碎量和飞石的速度也随之剧增After repeated field experiments, they drew a conclusion that as the charge increases, the fragmentation and the velocity of the broken material increases as well
要想评价气象影响、务必要知道地面上空并且最好在900 米以上的大气温度和风速Evaluations of meteorological effects require that the air temperature and wind velocity be known at levels above the ground,preferably up to 900 metres
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

通过测量得知、由于温室气体的排放、大气二氧化碳浓度正在不容置疑地逐年加速增加The measured atmospheric concentrations of carbon dioxide show an inexorable and accelerating year-on-year increase arising from greenhouse gases emissions
