有斜切模型的喷管形状不对称，内流在出口处产生的扰动在较长一侧喷管壁反射，出现激波现象，引起流动的变化。
This paper briefly introduces the concept of oblique cut in economical LOM for metal part, mainly researches on material, structure and parameters of special oblique milling cutter.简要介绍经济型金属零件LOM技术倾斜切削的概念，重点对倾斜切削专用铣刀的材料、结构及几何参数进行了研究。
The bottom of the disc is made of knife-shaped gate with a cut off function of the medium. When gate is closed, oblique plane of gate valve encounters wedge block of gate to achieve sealing effect.闸板底部做成刀形斜面具有切断介质功能，而且闸板关闭时通过阀体上的锲块紧靠闸板斜切面使得闸板紧紧贴靠阀座密封面，从而起到了密封效果。
