本文在一阶速度滑移和温度跃变边界条件下，对稀薄气体介质中冲击起动的无限长垂直平板绕流的Stokes问题进行了精确分析。研究了自由对流对平板的外部加热或冷却的影响。观察到，当平板被自然对流冷却时，可能存在反向流动。传热速率随温度跃变系数h%的增大而减小
An exact analysis of Stokes' problem for the flow past an impulsively started infinite vertical plate in a rarefied gas-medium has been presented under first-order velocity slip and temperature jump boundary conditions. The effects of an externally heating or cooling of the plate by the free convection currents are studied. It is observed that there may exist a reverse type of flow when the plate is being cooled by the free convection currents. The rate of heat transfer has been found to decrease with increasing the temperature jump coefficient h%
