日全食期间雷电脉冲主频率的概率分布估计

本文利用日全食期间雷电信号的频谱分析结果, 研究了雷电脉冲信号主频率的概率分布, 并与非日全食期间的日常雷电信号作了比较。结果认为:日全食期间雷电脉冲的主频率服从高斯分布, 其均值μ和根方差σ的95％置信区间分别为8845赫芝≤μ<10381赫芝和2485赫芝≤σ<3203赫芝;但是非日全食期间雷电脉冲的主频率不服从高斯分布, 它他的均值明显地低于日全食期间的主频率均值。 

THE ESTIMATE OF PROBABILITY DISTRIBUTION OF THE DOMINANT FREQUENCIES FOR THE LIGHTNING DURING AN ECLIPSE OF THE SUN

In this paper we estimated the probability distribution of the dominant frequencies for the lightning during a total eclipse of the Sun, using the spectral data from 1 It was pointed out that the dominant frequencies may follow a Gaussian(or normal)distribution, and the reliable region of mean and rms for dominant frequencies are 8845 Hz, 10381 Hz and 2485 Hz, 3203 Hz respectively.
