  1. Economization on energy, lightweight and environmental protection are its new trend. based on these reasons mentioned above, i completed the development of the miniature low - power atmospheric pressure altimeter system in the light of the basic principle of low power design for microcontroller system, and my development on it includes both hardware design, software programming, and low - power design

    基於上述原因，本文基於單片機系統的低功耗原理，完成了低功耗氣壓高度表的研製工作，主要包括整機的硬體設計製作，全部的軟體編程調試以及從硬體和軟體兩個角度降低功耗的設計，最後對功耗和高度等數據進行分析。
  2. 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
  3. The gas mixture flows through the detector with a pressure slightly above atmospheric pressure. prototypes of ppsd have been tested at cern ps ( proton synchrotron ) with beams of 1 or 2 gev / c in momentum

    P然d的兩個樣品分別於19 」和加朋年在cern外t10來流戲上進行了瀏試，效率達到」呱
