In this paper, some characteristics of turbulentexchange in surface layer, the austausch coefficient, heat flux transfer, etc.
本文对于北京冬半年近地面层湍流的特性：湍流系数及湍流热通量等，用各种方法进行计算和比较。

Comparing with the flux of turbulentexchange of latent heat and the flux of upward long-wave radiation the flux of sensible heat exchange is very small.
与潜热的湍流输送及海表面向上的长波辐射通量相比，感热的湍流输送量很小。

The findings bring new lights in the fluctuating nature of momentum exchange coefficients and integral time and length scales. These turbulent properties should not be assumed constant.
