回答1：

与表面直接接触的流体由于导热而被加热，变轻，并且由于与相邻流体的密度差而上升。这种运动由于流体粘性而受到阻碍。1、热传递受下列因素影响:因热膨胀而引起的重力作用，2、粘性阻滞及热扩散。这种热传递被认为取决于重力加速度、热膨胀系数、运动粘滞系数，及导热系数。
对不同几何形状、辐射特性和方向的表面，估计它们之间的传热速率时，常假定：1、所有表面均是灰的或黑的，2、辐射和反射式漫射，3、整个表面参数均匀一致，4、吸收率等于发射率并且与投射辐射源的温度无关，5、两辐射表面间的物质既不发射也不吸收辐射。这些假设由于它们提供的简化程度很大而被使用，虽然得出的结果只能认为是近似的。
And surface contact fluid due to thermal conductivity and heated, lighter, and because the density difference with adjacent fluid increase. This kind of sport because fluid viscosity and hindered. 1 and heat transfer by the following factors: caused by thermal expansion of gravity, 2, viscous block and thermal diffusion. The heat transfer is considered depends on gravity acceleration, thermal expansion coefficient, sports viscous coefficient, and the coefficient of thermal conductivity.
For different geometric shape, radiation characteristics and the direction of the surface, estimate the transfer rate between them, often assume: 1, all surfaces are grey or black, 2, radiation and the reflex diffuse, 3, the entire surface parameters uniformity, 4, absorption rate equals emissivity and has nothing to do with projected emitters of temperature, five, and two radiation surface between substances do not emit also does not absorb radiation. These assumptions because they provide simplified degree is used, although very the results of only think is an approximate.

Direct contact with the surface of the fluid, because of heat and heat, light, and with the neighboring fluid the density of a rise. this motion because of sticky fluid and blockaded. 1 and heat passes by the following factors: the heat of the expansion of gravity, 2, and the proliferation of delaying action for the hot sticky. the heat transfer is considered on gravity and acceleration of hot, sticky in the expansion of the motion, and thermal coefficient. the geometry, radiation and direction of the surface, it is estimated that they

回答4：

heated, becomes lighter, and because of the density difference between the fluid and the adjacent rise. This movement have been hampered due to fluid viscosity. 1, heat transfer by the following factors: due to thermal expansion caused by gravity, 2, viscous and thermal diffusion block. This heat transfer is considered to depend on the acceleration of gravity, thermal expansion coefficient, sports viscosity coefficient, and thermal conductivity

2.Different geometry, the direction of the surface radiative properties and the estimated heat transfer rate between them, often assume that: 1, all surfaces are gray or black, 2, diffuse radiation and reflection, 3, the entire surface uniform parameter, 4, and the absorption rate equal to the emission rate has nothing to do with the projection of the temperature of radiation, 5, the material between the two surfaces is neither radiation nor absorbs radiation emission. These assumptions because they provide a great degree of simplification was used, although the results can only be considered approximate.
