  3. By employing cole ' s classical theory of bubble dynamics, the motion of bubble produced by the underwater explosion and the corresponding bubble pulsating pressure are calculated. a profile function of the shock wave and its parameters are determined according to the principle of wave profile similitude and the equality of impulses. finally an analytic formula is derived to simulate the whole time history of the pressure from the front shock wave to the bubble pulsation, representing the fluid loadings of the underwater explosion

    木文首先應用庫爾的經典水下爆炸氣泡運動理論計算出氣泡的運動和脈動的壓力波形，再依據波形相似的原則尋找波形模擬函數，用沖量相等的原則確定波形參數，得出了從沖擊波到氣泡脈動壓力整個過程對水下爆炸載荷進行模擬的解析公式。
  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
