提出了一种描述正日冕流光在大气中非均匀场隙低场区传播的模型。它已经假设生长是一个性质，仅仅是流光尖端，不受通道电导率的影响。模型计算表明，在零外场条件下，流光的传播准则是尖端离子数为108个，半径约为3×10−3cm。本文提出，由于通道中离子对的形成，导致尖端能量损失，导致流光停止传播。将以往的实验观测结果与模型计算结果进行了比较，并讨论了模型对去电压后拖缆寿命的预测。
A model is presented to describe the propagation of positive corona streamers in the low field region of a non-uniform field gap in atmospheric air. It has been assumed that the growth is a property solely of the streamer tip, uninfluenced by the channel conductivity. Calculations from the model indicate that the criterion for propagation of a streamer in zero external field is that the number of ions in the tip be 108and the radius about 3×10−3cm. It is proposed that the streamer ceases to propagate as a result of the loss of energy of the tip due to the formation of ion pairs in the channel. The results of previous experimental observations of streamers are compared with calculations derived from the model, and a prediction from the model of the lifetime of streamers after voltage removal is discussed.
