| 中文摘要: |
| 弥散系数是地下水污染数学模型的基本参数.本文提出一种获得纵向和横向弥散度的野外试验新方法.该法能很好地控制野外试验的水位和流场形态，提高地下水坡降，且方便可行.同时还介绍一种与配线法不同的，用联立方程迭代求解的弥散度新算法。 |
| 英文摘要: |
| A new method for field tracing test of groundwater dispersion is presented. By using this method the longitudinal and transverse dispersivities can be obtained simultaneously. The method can well control groundwater level and flow pattern, increase the gradient of groundwater table in field test. In addition, the calculation formulas for dispersivities are deduced by solving simultaneous equations. |
