运用灰色理论和方法，通过对前混合磨料射流切割试验的分析，获得了压力、靶距、磨料浓度、横移速度影响切割的主次关系。
The cutting property is studied with the grey theory and method for the premixed abrasive water jet.The relationship between the primary and secondary is obtained about the cutting specific energy influenced by pressure,the standoff distance,the abrasive concentration and transverse velocity.The guidance is provided for further research and pratical application.
