摘要：

In order to understand thermochemical non-equilibrium phenomena which occur during re-entry, shock stand-off distances oil a simple hemi-spherical model were measured in a high enthalpy shock tunnel. Moreover, from the measurements, the unresolved question of how much influence un-recombinated oxygen atoms and vibrationally excited molecules related to the frozen phenomena of nozzle flows have oil the flow was investigated. It was also discussed whether a binary scaling parameter which indicates a non-equilibrium process call accommodate the nozzle flows of a shock tunnel.
