摘　　要：本文通过前置导管的数学模型,用流体奇点法推导的公式进行了一些数值计算。经过比较分析,提出了一种不对称前置导管的等价数学模型。对前置导管形状、位置与水动力性能的关系也作了有实际意义的探讨。In this paper numerical calculations are accomplished by formulas derived from hydrody-namical singularity distribution method and symmetrical nozzle mathematical model. The equivalent mathematical model of unsymmetrical nozzle is presented on the ground of the analysis and comparison. The relations between shape, location, and hydrodynamical characteristics of a nozzle installed in front of a propeller are also discussed with practical significance.
