| 摘 要： | 利用硅光电二极管探测器，对2008年夏季广东省从化地区和北京昌平地区的自然闪电光辐射信号进行了观测研究，并对获得的312个观测数据进行了统计。得到如下结果：光辐射脉冲峰值为［10.97(5.55)±12.46］ mW/cm2，10%~90%光脉冲前沿为［1.14(0.44)±2.02］ ms，50%~50%光脉冲宽为［1.44(0.49)±2.07］ ms，一次闪电包含的光脉冲数为［3.78(3.00)±2.30］个；将统计结果与FORTE卫星上的硅光电二极管载荷的探测结果进行了对比，光脉冲峰值要大1~2个量级，脉冲宽度要小，符合对闪电光辐射信号传播的物理过程分析。

| Abstract: | The lightning optical signals were measured by a silicon photodiode detector(PDD) at Conghua city Guangdong province and Changping district Beijing city in summer, 2008. Totally, 12 observed data were analyzed statistically. The maximum optical peak magnitude is ［10.97(5.55)±12.46］ mW/cm2, the 10%-90% pulse rise time is 1.14(0.44)±2.02 ms, the 50%-50% pulse-width is ［1.44(0.49)±2.07］ ms and the single lightning optical peak count is 3.78(3.00)±2.30. The radiance peak is one to two orders of magnitude more and the pulse-width is broader, compared with the FORTE’s PDD data. These results are reasonable according to the lightning radiance mechanism and physical evolution process. |
