中文摘要	通过以系留气球和探空气球为平台的方式,搭载温度脉动仪在戈壁地区对大气折射率结构常数开展长期测量。对获取的实验数据开展统计分析,探讨了在白天与夜间折射率结构常数的平均情况、高度分布、偏度与峰度、季节的强弱特性等四个方面的内容,结果表明:在测量地区,随高度分布的大气折射率结构常数在白天和夜间的算术平均值和对数平均值的比值会有较大的差异,并且白天和夜间的对数平均值和标准差系数随高度分布各有其特点,表现在随高度整体减小的同时会有起伏出现,尤其是夜间;白天和夜间的偏度与峰度主要表现出右偏和尖峰特性,在高度分布上有所不同;季节变化对湍流的强弱分布产生明显影响,集中体现在中性湍流和弱湍流分布情况随高度发生交互变化。
英文摘要	Using the platforms of captive balloon and sounding balloon equipped with micro-temperature sensors, atmospheric refractive index structure parameter(C_n~2) had been measured in arid area for a long time. A statistical analysis based on experimental data of atmospheric refractive index structure parameter was carried out about the average C_n~2 in daytime and nighttime, distribution of standard deviation on height, skewness and kurtosis, as well as the strength characteristics of seasonal variation. The obtained results show that there is a great difference on the ratio of arithmetic mean and logarithmic mean between day and night, the logarithmic mean value and standard deviation coefficient of C_n~2 in daytime and nighttime generally decrease with height while they fluctuate at the same height, especially in nighttime; the difference of the right skewed and leptokurtic characteristics between day and night were indicated for different heights; seasonal changes have significant impact on the strength of turbulence distribution, as for the median turbulence and weak turbulence distribution change interactively at different height.
