同位素技术用于水文地质领域可以解决许多常规方法难以解决的实际问题。用放射性同位素做示踪剂的多孔脉冲技术结合稀释法测定层状含水层的有效孔隙度和渗透系数,方法直接,所求参数精度较高,代表性强,是水文地质求参的新途径。 The use of isotope techniques in the field of hydrogeology can solve practical problems that many conventional methods can not solve. The method of porous pulsed radioisotope tracer combined with the dilution method to determine the effective porosity and permeability coefficient of the layered aquifer is straightforward and requires high accuracy and representativeness of the parameters to be obtained. It is a new way of seeking reference for hydrogeology.
