| 摘 要： | 将描述两个观测孔的瞬时投放示踪剂、一维稳定流场、二维非稳定水动力弥散过程中的示踪剂浓度,在时空上变化的解析解分别进行了对数变换,可以推导出两个直线方程.根据适当的数据转换,能够分别得到两个直线方程中的自变量和因变量,它们均为试验观测数据的函数,而直线方程中的常数含有待求的含水层水动力弥散参数.因此,对试验观测数据进行适...

| Abstract: | In this paper,the logarithmic transformation for the analytic solution on the space-time change of the tracer concentration during the test process of one dimensional steady flow field and two-dimensional unsteady hydrodynamic dispersion field with instantaneous injection is performed,and then two linear equations have been derived for two observation wells.The independent and dependent variables of two linear equations are all the functions of observation data of tracer test,and the linear constants includ... |
