[文摘]:Numerical simulations were carried out for the flow separation in overexpanded rocket nozzle flows, using the Beam-Warming approximate factorization method to solve thin-layer Navier-Stokes equations. The results indicate that the separation position was determined by the ratio of total pressure to environment pressure. The area ratio of the nozzle has little influence on separation for the same divergent section. For the longer divergent section, the area ratio in which flow separates is smaller. (Author)

[文摘]:Analyses of meteorite matter, the present structure of the solar system, and the evolution of matter in stellar systems are used to provide inferences concerning the formation of primordial matter in the solar system. Results indicate that molecular excitation processes similar to those observed today in circumstellar regions and dark interstellar clouds were operating in the early solar nebula. It is suggested that resonance excitation of broad isotopic bands by strong UV line sources may have resulted in the anomalous isotopic compositions noted in meteorites. (R.R.)
