  一维水质模型，本程序研究一维河流的污染物扩散，短时间持续排放BOD的浓度变化规律 本程序采用中心隐式差分求解 问题t=0到t=1h偶然排放BOD 使河水断面L0=10mg/L河流平均速度5km/h 纵向弥散系数D=2km2/h BOD衰减系数k1=0.015h-1 解BOD浓度 L(x，t)(One-dimensional water quality model, the procedure of one-dimensional dispersion of pollutants in the river, a short continuous changes of the concentration of BOD emissions of the program implicit difference method with central issues t = 0 t = 1h accidental emissions to the BOD to the river section L0 = 10mg/L average speed of the river 5km/h vertical diffusion coefficient D = 2km2/h BOD decay coefficient k1 = 0.015h-1 Solution for BOD concentration L (x, t))
