摘　　要：根据石臼港罗丹明B和大红颜料扩散实验结果以及三维剪流扩散解析解,计算了石臼港污染物(点源)三维扩散的垂直、横向和纵向扩散系数,它们分别为(cm^2/s):2.0,1.4×10~3,1.4×10~4。连续源扩散系数与点源纵向扩散系数非常接近,量值为(cm^2/s):1.5×10~4。3-D diffusion coefficients for Shijiu Harbour are computed based on the analytical solution for a, 3 D instantaneous point-source shear diffusion (Zhang Fagao, 1980) and the data of Rhodamine-B and red dye diffusion experiments in this area. The computed values of the diffusion coefficients for an instantaneous point-source in the vertical, the lateral and the longitudinal direction are 2.0, 1.4×103 and 1.4×104 cm2/s respectively.The computed diffusion coefficient for a continuous source is 1.5×104 cm2/s, almost equal to that of the longitudinal diffusion coefficient for point-source as above mentioned.
