结果表明,磁化等离子体结构在磁应力下不可逆地松弛到最小应力状态,只要存在磁零点,其松弛速率基本上是阿尔芬尼定律。弛豫是通过零场处的重新连接来实现的,并且以与 ln(eta) exp-1 的绝对值成比例的速率进行,其中 eta 是电阻率。提出了线性状态下的解析计算。 10 参考文献
It is shown that magnetized plasma configurations under magnetic stress relax irreversibly to the state of minimum stress at a rate that is essentially Alfvenic provided a magnetic null is present. The relaxation is effected by the reconnection at the field null and proceeds at a rate proportional to the absolute value of ln(eta) exp-1, where eta is the resistivity. An analytic calculation in the linear regime is presented. 10 refs.
