环形是等离子体弹的特征之一。然而，关于等离子体子弹的环形结构的机制，仍然不清楚。本文通过一系列特殊设计的实验，对等离子体弹的环形结构的机理进行了研究。在这些实验中，表面放电的影响和周围气体扩散的影响，从而潘宁电离的影响可以分开。结果表明，在环形结构的形成过程中，周围空气的扩散和沿面放电都起着重要的作用。
Ring-shape is one of the feature characteristics of plasma bullet. However, regarding the mechanism of the ring-shape structure of the plasma bullet, it is still not clear. In this paper, a series of special designed experiments are carried out to investigate the mechanism of the ring-shape structure of the plasma bullet. In these experiments, the effects of the surface discharge and the effect of the surrounding gas diffusion, thus the effect of Penning ionization can be separated. It is found that both the diffusion of the surrounding air and the surface discharge play important role in the forming of the ring-shape structure.
