Shoemaker－Levy　9彗星撞击木星的流星物理学

METEORIC PHYSICAL PROBLEM IN THE COLLISION OF SHOEMAKER-LEVY 9 ON JUPITER

本文从流星物理学的基本方程出发，导出Ｓｈｏｅｍａｋｅｒ—Ｌｅｖｙ９慧星撞击木星时的速度、质量损失、电子线密度、能量释放率随高度的分布公式；采用合理的参数，作了一系列计算，并与观测资料比较，进行一些讨论．

The collision of comet Shoemaker-Levy 9 with Jupiter is essentially a particular meteoric physical problem during the cometary fragments into Jupiter's atmosphere. In this paper, profile formula of their velocity, mass loss, luminosity, electron line density and energy release rate on height are derived from fundamental equations of meteoric physics. Using reasonable parameters, a series of results are calculated. The results are compared with observations and discussed. It is shown that initial mass of the largest fragment of SL9 is of order 1016 g and do not penetrate into H2O cloud layer of Jupiter due to its airburst.
