摘　　要：结合某经济开发区排海工程，以水槽试验资料为击破，运用数学模型和量纲分析对动水、密度均匀的水流条件下，双喷口、异向射流的近区稀释扩散进行了研究.通过模型试验术出数学模型中的参数，探讨了环境流过、射流速反对近区初始稀释的影响，并以物理模型的试验值校核教学模型，证明该模式具有一定的可信度.In this paper, the mathematical model and the dimensional analysis are used to study the near field's dilution and diffusion of double nozzle and counter jet in moving unstratified nuids on the basis of experimental data of nume. The parameters in the mathematical model are gained through the model test. The relationships between the initial dilution of the near field and the characters of ambient velocity and jet velocity are oxplored. In general, with the experimental data of physical model to calibrate the mathematical model, the results demonstrate that the model is valid.
