实践表明;在矿坑放水或地面抽水的定流量阶梯状捕(放)水试验中,从不同距离观测孔所反映出来的Q=f(s)关系极少近似直线,绝大多数成曲线关系,特别是在降深较大时更为显著。笔者体会,在阶梯状定流量抽水试验资料中,当Q=f(s)成曲线关系时,通过观测孔s与Q回归分析,则以其线 Practice shows that Q = f (s) relation reflected by observation holes of different distances rarely approximates straight lines, and the vast majority of them are in a curve relationship in the fixed-flow catching (releasing) water test of mine drainage or ground pumping. Especially in the deeper decline is more significant. The author understands, in the step-shaped constant flow pumping test data, when Q = f (s) into a curve, through the observation hole s and Q regression analysis, the line
