| 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(cm2/s):2.0, 1.4×103,1.4×104。连续源扩散系数与点源纵向扩散系数非常接近,量值为(cm2/s):1.5×104。 |

| 3-D DIFFUSION COEFFICIENT COMPUTATION FOR SHIJIU HARBOUR |
|
|
| Abstract: |
| 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. |
