| 摘 要： | 大气折射率结构常数C2n是表示大气光学湍流强度的重要参数.利用QHTP-2型温度脉动探空仪对C2n进行了实地探测,通过对大量探空实验数据的统计分析得出了合肥地区0～35 km高度C2n分布廓线和日变化特性,对合肥地区的大气湍流结构特性有了比较清晰的认识,研究结果为进一步进行湍流特征和大气性质的遥感探测及实际激光工程应用提供了有意义的参考.

| Abstract: | Research of light-transfer in atmosphere is actually investigation of atmospheric refractive index variation caused by atmospheric turbulence. The atmospheric structure constant of refractive index Cn2 is an important parameter of atmospheric turbulence intensity. Cn2 was measured using QHTP-2 micro-thermal meter. The vertical profile of Cn2 and daily variation were investigated by analysis of experimental data in Hefei with 0-35 km height range, and structure characteristics of atmospheric turbulence were given. Results are significant to further turbulence characteristics research, remote sensing of atmosphere characteristics and laser engineering applications. |
