| 摘 要： | 探讨瞬时点源污染带几何特征，给出污染带中心位置，长度，宽度及面积等计算公式，并证明了当Ｃｍ＝Ｃ０ｃ时超标污染带面积达最大值Ｓｍ＝Ｍ／ｈＣ０ｅ，表明此值仅与污染物投放量Ｍ、扩散水深ｈ和预先给定的浓度Ｃ０有关。

| Abstract: | The geometric feature of instantaneous point source pollutant zone is discussed. The equations for describing its central position, length, width and area are presented.It is demonstrated that the over standard pollutant zone reaches it maximum size which is presented by S m= m/hC 0e under the condition of C m= C 0 e.In the equation, S m varies with the quantity of pollutant discharged, dispersion water depth( h ) and initial concentration( C 0) |

| Keywords: | instantaneous point source pollutant zone feature the maximum over standard area |
