本文介绍了一种解释的存在之间的过渡区注入和含水层的沃茨，通过渗透性水平分层含水层，其中假设渗透率的频率近似遵循正态分布函数的流动的假设。由水平分层流引起的过渡区的宽度与行进距离成正比，而由分散引起的过渡区的宽度与行进距离的平方根成正比。据信，在自然界中，分散和水平分层流同时发生，因此过渡区的形状和宽度是这两个过程的结果。描述和解释了在海法湾实验场进行的“注泵对”型现场实验。试验场的研究结果适用于大规模地下回灌和混合作业。(13参考文献）
This paper describes an explanation of the existence of a transition zone between the injected and the aquifer's waters, developed on the assumption of a flow through a permeability horizontally stratified aquifer, in which it is assumed that the frequency of permeabilities follows approximately the normal distribution function. The width of the transition zone caused by the horizontally stratified flow, is directly proportional to the distance travelled, while the width of the transition zone caused by dispersion is proportional to the square root of the distance travelled. It is believed that in nature the dispersion and the horizontally stratified flow occur simultaneously and thus the shape and width of the transition zone is a resultant of the 2 processes. A field experiment of the ''injection-pumping pair'' type carried out at the Haifa Bay Experimental Field is described and interpreted. The results of the investigations in the experimental field are applicable to large-scale underground recharge and mixing operations. (13 refs.)
