  1. In the theoretical aspect, performance analytical model of was proposed, in which allowances were made to allow for variable cross - sectional area, include the heat release of chemical reaction, and allow for mass addition. software was generated, and performance of rocket ejector was analyzed accounting for heat release location, flow parameters and structural configuration

    在理論方面，建立了引射火箭模態的性能分析模型，該模型考慮了化學反應放熱、加質和變幾何截面的影響；編寫了相應的軟體，並結合放熱位置、流動參數和發動機結構進行了引射火箭的概念設計。
  2. Skin effect is the tendency for alternating current to flow near the sruface of the conductor in lieu of flowing in a manner as to utilize the entire cross - sectional area of the conductor. this phenomenon causes the resistance of the conductor to increase. the magnetic field associated with the current in the conductor causes eddy currents near the center of the conductor which opposes the flow of the main current near the center of the conductor. the main current flow is forced further to the surface as the frequency of the alternating current increase

    表面疚是指交流電流較傾向于導體的表面傳導而非流經整個導體截面的趨勢，這些現象會造成導體的電阻提高，與導體中的電流有關的磁場在導體中心部位產生過電流而阻礙了中心部位的主要電流，當交流電的頻率增加時，主要電流的流向會進一步被推擠到導體表面。
