1、found that the star_shaped nozzle jet has a shorter initial section and slower velocity attenuation along the jet centerline in the main region than the round nozzle jet.───发现，星形喷嘴射流与普通圆射流相比，其射流初始段较短，但基本段内速度随喷距衰减的速率较低。
2、exploration of axle centre pressure attenuation rule proves that the effective injection distance is 9~15 times as much as the diameter of nozzle entry.───轴心压力衰减规律的探索，证明其有效喷距为喷嘴入口直径的9～15倍；
