(一)关于裘布衣基本方程式对于潜水,裘氏基本公式从 Q=2πrhK(-h/r) (1)求得的,他是基于了环形岛状定流量、常水头的稳定补给,并设初始水位是水平的,含水层是均质等厚的和迳流量在二维层流和缓变流的情况下导出的。即: Q=πK(H~2-h_1~2)/lnR/r_0 (2)后人不断指出(2)式的错误。诸如于r→R处,由于浸润方程式h=f(r)是一对数抛物线,是相剖而非相切,井近处流线弯度增大,其坡降应是h/r而非h/r,S→H,ω_(r_0)=2πr_0h|_(h→0)→0而非Q_(max)的矛盾等等。
(A) on the basic formula for fur diving For diving, Qiu basic formula from Q = 2πrhK (-h / r) (1) obtained, he is based on the annular island constant flow, constant head constant supply, and set The initial water level is horizontal, the aquifer is homogeneous and isochronous, and the 迳 flow is derived in the case of two-dimensional laminar flow and slowly changing flow. Namely: Q = πK (H ~ 2-h_1 ~ 2) / lnR / r_0 (2) People continue to point out (2) type of error. For example, at r → R, since the infiltration equation h = f (r) is a parabolic parabola, which is a phase parabola rather than a tangent, the streamline camber increases near the well and the slope should be h / r instead of h / r, S → H, ω_ (r_0) = 2πr_0h | _ (h → 0) → 0 instead of Q_ (max), and so on.
