本文根据近地面层湍流相似理论分析了我国东海海面和合肥市西郊一水库上方及水库附近地面上的气象参数与光学湍流参数一折射率结构常数C2/n/。结果分析表明,折射率结构常数C2/n/和大气稳定度很好地满足经验关系。由此可以得到：在陆地和海域上可以利用气象要素对折射率结构常数进行估算。

Turbulence has long beenrecognized as one of the must significant effects on the performance of optical systemsoperating in the presence of atmosphere. Of all the turbulent parameters, the mostimportant and used most frequently is refractivity structure constant C2/n/.Because of the relation between the refractivity and temperature, C2/n/can be calculated from he temperature structure constants C2/T/. But C2/T/is not easy to measure. In the paper, the meteorology data from the East China Sea and thereservoir on the west suburb of Hefei city and its vicinal land are analyzed. According toMonin-Obukhov similarity theory and semiempirical relationships of Wyngaard, thetemperature structure constants are obtained. and they give well agreement with C2/T/measured directly.
