  1. A new calculation method for optimizing diesel engine performance, called nonlinear regression - mess method, is put forward. in this paper, 25 groups of simulated values are calculated from the diesel engine working model, specific fuel consumption, peak pressure, rate of pressure rise, nox and peak temperature are fitted into explicit function about compression ratio and fuel injection advance angle

    本文利用柴油機工作過程模型，得出25組模擬計算數據，利用非線性回歸將油耗、最大爆發壓力、壓力升高率、 no _ x濃度及最高燃燒溫度擬合成壓縮比和噴油提前角的顯函數，並用網格法進行優化，用c語言編制了優化計算程序，得出最佳的壓縮比和噴油提前角，使其優化匹配。
  2. The result of analysis shows that the convective heat flux has main effect on fuel pyrolyzing and vaporizing, the liquid layer of pe fuel can increase the regression rate but also can cause unstable burning. 4

    研究結果表明：對流熱流是引起燃料熱解氣化的主要因素， pe熔化產生的液體層提高了燃料熱解退移速率，但液體層厚度增加到一定程度時，對發動機工作穩定性有負面影響。
  3. Combining with the energy fluxes balance above fuel surface, the simulation and calculation of transient heat conduction of the pe fuel with liquid layer while melting and pyrolyzing are considered by use of the moving coordinates. the calculated regression rate of the pe fuel approximately tallies with the same kind of hybrid rocket motor test data from the abroad

    建立了pe燃料的熔化、熱解、導熱模型，應用動坐標系，結合燃料表面熱環境，對具有液體層的pe燃料的熔化、熱解和內部瞬態導熱過程進行了模擬計算，計算的pe燃料退移速率與國外同類試驗的測量結果符合較好。
  4. The reasons for higher oxidizer flow rate, lower fuel regression rate and lower motor performance in both hot firings are discussed. several necessary improvements for the test system are suggested. 6

    通過對兩臺發動機試驗結果的分析，找出了試驗中氧化劑流量偏高、燃料退移速率和發動機性能偏低的原因，並提出了具體的改進措施。
  5. The results of research indicate that the pressure, the thrust and the fuel regression rate of the motor decrease while the o / f ratio increasing with the burning time lasting. the special impulse reduces when throttling

    研究結果表明：壓強、推力和燃料退移速率隨發動機工作時間增加而降低，氧化劑和燃料的配比升高；節流時，發動機比沖降低。
