在不规则的三角形网格上，采用改型特征线法处理对流算子；采用集中质量的有限元法处理扩散算子，应用数值求解对流扩散方程的分步杂交法，模拟浅水型湖泊的水力特性，计算了1993年三个季度在不同风应力及入出流作用下的流态、流场分布、水位变化情况．
In the irregular triangle grid, the modified characteristic line method is adopted to process the convection operator. The diffusion mass is solved by the finite element method of the concentrated mass. The stochastic method of numerical solution to the convection-diffusion equation is applied to simulate the hydraulic Characteristics, calculated in 1993 three quarters under different wind stress and the inflow of flow, flow field distribution, water level changes.
