Terms for subject Explosives and Explosive Ordnance Disposal containing Back

English	Chinese
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	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
back azimuth method	反范围角定位法
back blast	反向爆破
back break	超挖超出预期崩落区的岩石排放。超爆的岩石量取决于所使用的爆破方法、岩石的结构和强度、地下岩洞开口的大小，参见 overbreak
back break	后裂最后排炮孔限界之外的岩体破裂
back canch	挑顶参见 backbrushing
back damage	顶板危害由于爆破使隧洞顶板的岩石强度降低
back elevation drawing	后视图
back explosive	退库炸药携往爆破现场的炸药,没有使用或用剩后需送回炸药库的行为，称作退库。而返回炸药库的炸药则称为退库炸药
back hole	顶板孔巷道或回采区中顶部的炮孔
back holes	后爆炮孔组

displacement back analysis for rock engineering	岩体工程位移反分析法用开挖过程中实测的围岩位移推算围岩的力学参数或岩体中的原始应力场的方法。在分析开挖体稳定性问题时，位移和变形通常是作为待求量出现的，因此,测位移、求参数的分析称为反分析
distance of back stroke	后冲距离
fire back in selfdefence	自卫反击
height of back upturn	后翻高度
