摘　　要：本文对伴流环境中,由于盐分浓度差形成的浮力射流进行了实验研究。采用测量电导率的方法测量射流内部盐分的浓度分布。实验表明,浮力射流的横断面内浓度呈椭圆形高斯分布。不同于测量比重的方法,本方法简便易行,且具有较高精度。Experiments on buoyant jets due to sality difference have been conducted in the present study. Concentration distribution has been obtained by measuring conductivity in the buoyant jets. It is shown that concentration in the jet cross—section takes elliptical Gaussian distribution. Comparing with the method by measuring specific weight, the present one has higher accuracy.
