Abstract : to bring forward the calculative method of producing dust capacity in blast work . the difficult problem is solved to judge the effect of dustproof , because of the mensuration position 文摘:提出爆破作业后产尘量的计算方法。解决了由于爆破地点和测定位置的变化,而难以衡量防尘效果的难题。
When the soil water properties and soil water - storage was studied with traditional statistic method , samples were entirely independent and obeyed normal distribution , not taking into account spatial relative of sampling location 在用传统统计方法分析土壤水分特性和土壤水库贮量时,根据finsher统计原理假设样本之间完全独立且服从正态分布为前提,不考虑测定位置的空间关系。
