中文摘要：
针对小型暂冲式超声速风洞进行的诱导激波实验结果，提出等离子体气动激励诱导激波的机理不仅取决于放电时产生的焦耳热效应，放电区域的边界层厚度也起到了决定性的作用的推论。为进一步验证此思想，在高超声速激波风洞进行了等离子体气动激励诱导激波的实验研究。结果表明，在边界层很薄的情况下，等离子体气动激励能够诱导出斜激波。分别阐述了两种实验条件下诱导激波的机理，证实了边界层效应在等离子体与激波相互作用中起到了决定性作用。
英文摘要：
Based on the experimental result of inducing shock wave in a small-scale short duration supersonic wind tunnel, this paper illustrated the theory of inducing shock wave that was not only lied on Joule heating effect but also decided by the discharge area thickness of boundary layer. Moreover, the experimental investigation on inducing plasma shock wave in the hyper sonic wind tunnel in order to confirm such theory drew the conclusion that under the condition that the boundary layer is very thin the plasma aerodynamic actuation could induce oblique shock wave. This paper discussed the theory of inducing shock wave in these two different conditions and also confirmed the key effect of boundary layer in plasma and shock wave interaction.
