Self-recording system is devised and used to measure potential gradient at Yenching. In fine weather the results show two maxima and two minima for a whole day. During raining potential gradient is constant at zero value, except when lightening and thunderstorm occur in which case the potential gradient changes rapidly both in magnitude and direction.

The Austausch coefficient may be obtained by wind structure. 1902 Ekman established the wind spiral theory in the friction layer. From the observed wind spiral, we may calculate of the Austausch coefficient by this theory. 1952 considered effect of the change of pressure field with height; i. e. the thermal wind effect, and found excellent results. But, Formula holds only for the condition in the stationary current flow, or in the stationary temperature pressure field and uniform temperature pressure gradient.In this paper, we consider the unstationary effect, as calculating the Austausch coefficient in the friction layer, and obtain a more general formula. Under some special constrains, it tends to be the or Ekman's formula. Then, this formula may be more accurate in calculation and more wide in application.Some calculations based on observed data by using these three different formulas are presented and compared.

摩擦层中湍流系数,利用风标的分布,可以测定之。1902年,爱克曼创立了摩擦层中风标螺线,利用风标螺线,可以测定摩擦层中的湍流系数。1953年,莱赫特曼考虑了气压场随高度的变化,即热成风的因素,获得了良好的结果。但是,莱赫特曼公式之应用,只限定于恒态吹流,或恒态均匀温压场的条件之下,方能准确使用。这样是在一般情况之下难以满足的。关于摩擦层非恒态问题,1947年赵九章、裘碧克曾经讨论过。本文仅就非恒态湍流系数测定问题予以进一步探讨。并得到了较有广泛意义之公式。而莱赫特曼公式,系属温压场恒态,温压场中温度、压力梯度在均匀情况之下,该公式之特解。爱克曼范式,系属气压场稳定,温度梯度恒态为零时,该公式之特解。这样,该公式的计算,使得湍流系数测定工作精确化和广泛化。 最后,本文作了一些实际资料的计算与分析,和讨论在自然环境中湍流系数的变化。
