摘　　要：对定常射流做了简要的评述。采用有限差分法，数值模拟了具有档板装置的高压气体射流，得到了射流早期的不定常结构，解释了发射器叶子板常遭受破坏的现象和机理。The steady shoot fluid is discussed brief in this paper and numerical simulations of the question concerning the high pressure gas shoot fluid with traught deflector have been made by using finite difference method. Early phase inteady structure has been provided. The phenomenon is explained that traught deflector of the shoot equipment were destroyed. It will provide the foundations to choose plan for design and the protection.
