项目摘要
Sprite is a characteristic discharge phenomena observed in upper atmosphere. It has diffuse and branching structure simultaneously. Sprite like discharge structures were created in laboratory experiment using a UV laser for controlling pre-ionization distribution. In order to understand the mechanism of the branching formation, the Sprite like discharge was focused. The branching was influenced by the density of pre-ionization created by a UV laser irradiation. Applying a fast-framing camera that can acquire 10^<9> frames per second, detailed growing phenomena of streamer was firstly observed. The suppression of branching in the relatively higher pre-ionized region and autonomous propagation phenomena suggested that the origin of the branching is similar to growing surface phenomena.
精灵是在上层大气中观察到的一种特征出院现象。它同时具有分散和分支结构。使用紫外线激光器在实验室实验中创建了像排放结构,以控制预电之前的分布。为了理解分支形成的机理,聚焦精灵的排放量是集中的。分支受到紫外线激光照射产生的预电之前的密度的影响。首先观察到可以使用每秒获得10^<9>帧的快速框架摄像头,首先观察到详细的彩带现象。在相对较高的预电区域和自主繁殖现象中对分支的抑制表明,分支的起源类似于增长的表面现象。
