  1. The coupling from the pulse jet in the nozzle to the unsteady flow in the tube was discussed. and the relations between the parameters of gas charge and discharge, structure, working, flowing in tube and ideal cooling efficiency were established. the theory foundation of the influence of pulse jet on the flowing in the tube and characteristic would be built

    探討了脈動射流與管內非定常流動的耦合問題，建立了脈動射流有關參數如進、排氣參數、結構參數、運行參數等和振蕩管內流動參數及理想製冷效率之間的普遍聯系，為研究脈動射流參數對振蕩管內流動及其性能的影響打下了理論基礎。
  2. The jet noise theory is used to analyze noise produced during the opening period of the suction or discharge valves in a similar way, theoretical calculations are made

    根據噪聲產生原理，指出降低噪聲的根本途徑是降低氣流通過氣閥前後的壓力損失，並給出降低氣流噪聲的主要途徑是：提出減小閥片剛性、厚度以及擴大排氣孔孔徑等。
