Based on the theory of aerothermodynamics for rarefied gas, discusses the principle of compound heat transfer in the vacuum layer.

应用稀薄气体分子热运动理论，研究了真空层复合传热机理，提出了真空层当量导热系数计算方法，分析了不同真空层压力和热媒温度对真空层传热量的影响以及导热、对流和辐射传热量在真空层总传热量中所占比例和变化规律，提出优化真空保温管道保温性能的方法。

At high latitude, besides thermospheric disturbances, we mainly study particle precipitation, convection electric field, neutral molecule excitation and top plasma flux, which may affect the ionospheric F region disturbance.

Computation of flow field is divided into two parts: one is comparison of turbulent model, and the other is influence of Froude number on the free surface.

圆柱绕流问题已经有很多年的研究历史了，但是考虑湍流模型和自由面对流场影响的文献不多。

The governing equation with chemical reacting flow is established. Using time splitting algorithm, the convection term is solved with the second-order Godunov method and the chemical reaction is coped with two-step model. Standing oblique detonation waves induced by an accelerating projectile are simulated numerically. The results are compared well with the data of the experiments.
