摘要
阐述了人工引雷技术的原理,结合2008年夏季在大兴安岭松岭地区进行的人工引雷实验情况,具体介绍了利用火箭拖带细金属导线进行人工引雷的专门技术,包括场地布局、所采用的技术手段及部分试验结果。通过电场变化的同步测量和光学观测,揭示了人工引雷的放电特征与自然闪电有极大的相似性,提出了人工引雷技术在研究雷击效应和引燃林火机理方面的具体应用以及主动防御森林雷击火灾的潜力,探讨了近距离同步测量云地闪电回击电流、量化分析雷击火机理的物理模式。
The principle of artificially triggered lightning is stated and based on the artificially triggered lightning experiments conducted in Songling area of Daxing＇anling in 2008, the special technology of artificially triggering lightning by using a rocket pulling a thin wire is introduced in detail, including field layout, technical measures taken and partial experiment results. Through the simultaneous measurement and optical observation of the change in the electrical field, the striking similarity between the discharge characteristics of artificially triggered lightning and natural lightning is revealed, the concrete application of artificial lightning trigger technology in the research into lightning stroke effect and forest fire ignition mechanism and the potentiality in initiative prevention against forest fires caused by lightning strokes are presented, with the physical modes for short distance simultaneous measurement of the return stroke current of cloud and earth lightning and quantitative analysis of the mechanism of lightning -caused fires discussed.
