摘要
文章回顾了射砂紧实机理的各种学说,指出了动能紧实说的不足,论证了气流总压强形成的高气压区在射砂过程中的作用,提出了新的射砂紧实机理。
The paper puts a review on the theories of shooting compact mechanism and points out the drawback of the theory of kinematic compact.Besides,the effe- cts of high pressure zone formed by the gross pressure intensity of air stream in the sand shooting process are expounded and proved.A new compact mechanism of sand shooting is presented.
