摘　　要：通过改变温度条件下的二维砂槽水动力弥散实验,分析温度对弥散作用的影响,探讨弥散度在时间和空间上的变化规律,以及分析分子扩散作用在横向弥散和纵向弥散中的作用。By studying the method of changing the temperature conditions of the two-dimensional （2 - D） hydrodynamic dispersion experiments in sand launder, the effect of different temperature on dispersion has been analyzed, the variation of dispersity on the spatial and temportal has been investigated, and the role of molecular diffusion in lateral dispersion and longitudinal dispersion has been analyzed.

关 键 词：温度 砂槽水动力弥散 横向弥散系数 纵向弥散系数
