试验研究了靶距、射流压力，冲蚀时间及淹没水深对射流性能的影响关系，对淹没水射流冲蚀性能作了全面分析，并将试验结果进一步应用于清洗工程中，取得了较好效果。
The effects of target distance, jet pressure, erosion time and submerged water depth on the jet performance were studied experimentally, and the erosivity of submerged water jet was comprehensively analyzed. The test results were further applied to the cleaning project and achieved good results .
