过筛 – phrases

Chinese	English
平均过筛粒度	mean passing size
很多实地操作人员把这种求导岩石系数的方法广泛应用于爆破剂破岩研究之中、并证明应用这种方法可以合理地估算所需的爆破强度以及诸多爆破环境下岩石的最终平均过筛粒度	This approach to the derivation of rock factors has been used by many field operators in a wide range of blasting and fragmentation studies and has been shown to lead to a reasonable estimate of the required blasting intensity and the resulting mean passing size in a wide range of blasting environments
有人证明使用这种破碎带模型、遇到各种岩石和爆破环境时、能可靠地估算过筛直径为1mm 碎岩的比例	The crushed zone model has been shown to provide a realistic estimate of the proportion of fragments passing 1 mm for a wide variety of materials and blasting situations
累计过筛百分数	cumulative percent passing
设定的过筛粒度	given sieve passing size
