非等温等离子体内的一种临界现象

应用等离子体的一般理论，讨论了非等温静态热平衡等离子体系统的电荷分离临界现象．提出此临界态的出现是系统处于外磁场和内部自激发联合作用下，形成的凝聚块发生流变所致．得到一个比Ｄｅｂｙｅ半径更一般的空间尺度判据．预期它将对自然界存在的电荷分离聚集系统（如：雷电系统）和荷电流体的流变性质（如：生命物质转运）等研究有参考意义．

The Critical Phenomenon in Nonisothermality Plasma

By means of general plasma theory,the critical phenomena, in which negative charge was dissociated from plasma and positive charge was left there,dissociating charge of plasma system in nonisothermality static equilibrium was discussed.It was advanced that the formation of the rheology of plasma condensata is the reult of interaction under the condition of external magnetic field and self-excitation in the system.A space criterion more general than Debye's was obtained.The criterion was of great importance to discripe the charge fluid such as the thunder cloud system and changing life material system etc.
