分析一维弥散试验数据的直线图解法

【摘要】 文中将描述一维、稳态和连续注入定示踪剂浓度条件下的半无限沙拉弥散试验过程的近似解析解进行适当的变换，使之成为一直线方程。该方程中的因变量和自变量的均含试验观测数据，直线常数为纵向弥散系数的函数，从而便可采用直线图解法或线性回归法确定弥散系数。更多还原

【Abstract】 Proper conversion conducted for approximate analytic solution of semi-infinite sand column during dispersion test under the condition of one-dimensional, stable state and injection of tracer with definite concentration and the formation of linear equation are stated in this paper. Observed data are included in the dependent variable and independent variable of that equation. The linear constant is a function of longitudinal dispersion coefficient, so it is feasible to determine dispersion coefficient with linear diagrammaticsolution or by linear regression.更多还原
