切削力随着水射流压力的增大而减少。
The cutting force reduce with the increase of water pressure.
结果表明：高压水射流的靶距、射流时间和水射流压力均对其冲蚀能力具有重要影响，三种参数在一定范围都存在影响冲蚀能力的平缓平台区；
The results demonstrated that there were important inferences by the three parameters such as time , distance and pressure for the ability of cavitation , and there was a flat in a certain extent.
模型采用三层结构，输入变量有水射流压力、水喷嘴直径、磨料粒子粒度(直径)、磨料流量和切割头进给速度。
Three layers network topology is adopted. The input variables are water pressure, diameter of orifice, diameter of abrasive particles, flow rate of abrasive and feed rate of cutting head respectively.
