Principal conclusions were drawn as the following : the non compatibility of pressure or velocity of the gas on both sides of the contact surface is the cause of the formation of shock wave ; the heating effect of reflective shock wave to driving gas during charging or exhausting process is the internal mechanism of peak oscillating effect, and all the factors that influence the formation and the running of the shock wave will influence the peak oscillating frequency, cooling effect
主要結論如下：熱分離機內激波形成的原因是射氣瞬間接觸面兩側壓力和速度不相容；峰值振蕩效應的內在機制為反射激波對充氣階段的驅動氣或低溫排氣的加熱，凡是影響激波形成及運動的因素都將對峰值振蕩頻率、冷效應及熱效應產生影響；當充、排氣時間比為0 . 1763時，最佳射流激勵頻率出現在高階峰值振蕩頻率上。 -
