  1. The optimal performance state ' s parameter of thermoelectric refrigerator under different work conditions was obtained on the assumption that the temperature in the cold side is invariable. and, the optimal performance state ' s parameter of thermoelectric refrigerator under the third kind boundary conditions was also obtained. the transmission of heat differential equation for the heat conduction process of thermoelectric module was derived and the solution with the first kind boundary conditions under the influence of thomson effect and the solution with the third kind boundary conditions without the influence of thomson effect was obtained

    在假設熱電製冷的熱端溫度固定的條件下，得出熱電製冷器在不同工況下的最佳工作參數並進一步求得在三類邊界條件下的最佳工作參數;導出了電偶臂在電與熱的偶合作用下傳熱微分方程，並對其進行解析求解:在考慮湯姆遜效應的影響下得出一類跟三類邊界條件下傳熱方程的解析解，在忽略湯姆遜效應的影響下得出二類跟三類相的邊界條件下傳熱方程的解析解。
  2. Abstract : the method of generating infrared image of target in the sky was proposed. at first, the geometric model of the target in the sky was built with grid ; secondly, using the theory of aerodynamic and heat transmission, the thermal equation of the different skin of target ( the skin with and without heat source, the skin with heat source and the skin of gasoline tank ) were established ; thirdly, as an example, the solution of the thermal equation of ultrasonic plane was obtained ; finally, the result of the computer simulation were proposed

    文摘:提出了空中目標的紅外圖像生成方法，首先是空中目標的幾何建模及其網格化，然後據飛機空氣動力學和傳熱學原理提出了空中目標幾種蒙皮（單層蒙皮、內有燃油蒙皮、發動機影響區蒙皮）的熱平衡方程，然後以超音速飛機為例，介紹了方程的求解過程，最後給出了計算機的模擬結果及分析。
  3. In the external region, heat transfer between the u - tube borehole and the ground is considered with a model of a finite line - source in a semi - infinite medium, and it is the first time to achieve an analytical solution of the temperature distribution for a such a transient two - dimensional conduction problem by means of the green - function method

    對單個鉆孔的傳熱劃分為兩個區域分別進行研究。在鉆孔周圍區域，將豎直u型管的傳熱簡化為有限長線熱源的傳熱問題，採用格林函數法首次得到了有限長線熱源溫度分佈的解析解。
  4. Green " s theorem is employed to find the quantity relationship among the constraints of heating rate, dynamic pressure and lift in reentry flight. the paper deduced the approximate solution of the optimal aeroassisted coplanar trajectories under the three typical constraints. the performance index to be minimized are either heat input, the total dynamic pressure, time during the atmospheric flight, the time integral of the square of the path inclination ; or maximize the time of flight during the atmospheric portion of the trajetory. an important conclusion is firstly obtained : under the three constraints above, the optimal aeroassisted coplanar transfers with the first forth kinds payoffs have the same optimal control laws

    採用格林函數法，給出了同一平面氣動力輔助變軌飛行的3種過程約束（氣動加熱率、動壓、升力約束）條件之間關系的近似定量描述形成的飛行包絡線.由此求解了航天器同時受3種約束條件時，各種性能指標下的同一平面氣動力輔助變軌軌跡的近似解及相應的最優控制規律.文中對近似解與控制規律的內部結構作了細致的分析，得到了一些有益的結論
