关于水环境中污染带长度计算与应用问题的讨论

通过采用不同方法对污染带长度进行分析计算，结果表明，在污染带长度的计算中，必须考虑边壁反射作用，而一般情况下，考虑2次边壁反射的计算结果即可以满足精度要求。本文通过对污染带长度应用问题的讨论认为：在实际工作中，不仅需要研究污染带长度，还需要对污染区域内污染物的实际浓度给予关注，两者结合，才能对污染范围和程度有更准确和全面的认识。

Discussion on Calculation and Application of Contaminated Zone in Waterbody

The length of the contaminated zone in waterbody is calculated and eompared by different means. It shows that the effect of boundary reflection must be taken into consideration in the calculation. Generally, the calculated results with twice boundary reflection are satisfied. Besides, the application of the length of contaminated zone is also discussed. To get more clear and comprehensive understanding on the extent and degree of pollution, not only the length of contaminated zone should be studied, but also the actual concentrations of contaminants in the zone should be considered.
