摘要
指出了闪电时形成的离子管形层流,其间歇流动产生涡环,提出了由若干导电离子流形成的涡环组合,它们间的相互作用构成稳定的球形闪电,该假设能解释球形闪电的形成、构造及其长寿命等基本性质.
It is pointed out that the ionic tubular layer flow is formed in lightning flashes and that its intermittent eurreat gives rise to the eddies. The interaction between the eddies that conduct electricity constitutes the stable ball lightning. This supposition can explain its basic characteristics concerned with its formation, straeture and the span of life.
