Positive corona burst pulses are an unstable pulse mode. They appear in a small range of the onset stage, and their current pulses result from the collective movement of charged species. This paper focused on the connections between these pulses and the collective movement of charged species. The movement of species is divided into four parts with respect to time: the (1) initial growth of species, (2) formation and development of the streamer region and negative ion sheath, (3) dead time (the time interval between the pulses), and (4) rapid re-growth of species. The movement of the species in the four parts and the correspondence with the current pulse were analyzed. The numerical results indicated the following: the rapid rising of the species matched the rising edge of the pulses, the streamer region, and negative ion sheath appeared in the falling edge of the primary pulse, and the rapid re-growth of species matched the re-ignition of the pulses. The results were in qualitative agreement with deductions and experimental observations in the literature.

正电晕脉冲是一种不稳定的脉冲模式。它们出现在开始阶段的小范围内，它们的电流脉冲是由带电物种的集体运动引起的。本文重点讨论这些脉冲与带电物种的集体运动之间的联系。物种的运动在时间上分为四个部分：（1）物种的初始生长，（2）流光区和负离子鞘的形成和发展，（3）死区时间（脉冲之间的时间间隔） )，以及 (4) 物种的快速重新生长。分析了四个部分中物种的运动及其与电流脉冲的对应关系。数值结果表明：物种的快速上升与脉冲的上升沿、流光区域、负离子鞘出现在主脉冲的下降沿，物种的快速重新生长与脉冲的重新点燃相匹配。结果与文献中的推论和实验观察定性一致。
