The turbulent pipe flow was visualized by solving the concentrationequation.
通过求解浓度方程得到了浓度场数据，并对流动进行了显示。
2
The first order and the second order of fully discrete discontinuous finite element schemes are proposed for the concentrationequation.
对浓度方程在时间上进行了一阶和二阶离散，采用间断有限元格式；
3
The mean concentrationequation of adsorbing solute transport in heterogeneous unsaturated soil was studied based on the spectrum analysis of the spacial random field.
