[文摘]:The present development history of U.S. commercial space activities traces some of the legal and policy changes effected in recent years and discusses why these may make the difference between success and failure in the future. Current thinking on space commercialization issues may be seen in the NASA Authorization Bill for fiscal year 1994-1995, under the description of the Advanced Space Technology Investment Program.

[文摘]:Results obtained in previous studies of the stability of a partially viscous shock layer suggest that any plane-parallel flow may be absolutely unstable if more than one normal instability mode exists for such flow. Here, this hypothesis is verified for a supersonic boundary layer at infinitely high Reynolds numbers. Two types of absolute instabilities, corresponding to two known types of dispersion relation branching, are identified. (V.L.)
