结果表明：下垫面温度突变引起的温度内边界层与下垫面粗糙度突变引起的速度内边界层具有明显的差异。
The results show that significant differences exist between the velocity IBL caused by the abrupt change of surface roughness and temperature IBL caused by the abrupt change of surface temperature.
热质交换边界层的温度梯度小于纯对流热交换边界层的温度梯度；
The temperature gradient of the heating mass-exchange boundary layer is smaller than that of the pure convective heat-exchange boundary layer.
