摘　　要：本文讨论了高速飞行体与空间等离子体相互作用的实验室模拟实验的可能性及编尺规律．虽然，所有重要参数的严格缩尺是不可能的，但是，航天器通过电离层等离子体的定性正确的缩尺是可能的，并给出了实验室模拟实验的缩尺因子．另外，为模拟航天器一电离层等离子体的相互作用，我们实现了等离子体束流流过模型的真空室模拟，即稳态等离子体风洞．In this paper, the possibility of laboratory simulation for the interaction between a high speed body and the space plasma and scaling laws are discussed.Although exact scaling of all important parameters is impossible, a qualitatively correct scaling is possible for the ionospheric plasma flow past spacecrafts. The scaling factors are proposed for the laboratory simulation experiment. In addition,we have carried out vacuum chamber simulations of the plasma flow around a model,a steady-state plasma wind tunnel, in order to simulate spacercraft-space plasma interactions in conditions corresponding to the ionosphere.
