Transport Coefficients of Plasmas with the Power-law Distribution in Strong Magnetic Fields
摘要/Abstract
在非广延统计理论框架下研究了非平衡态下的等离子体的输运系数,假设等离子体中的电子遵从非广延幂律分布,在此理论下得到用非广延参数q修正的输运系数,更便于研究等离子体的输运过程.通过输运方程和在强磁场下等离子体的分布函数,研究了遵从幂律分布等离子体的输运系数.推导出了遵从幂律分布等离子体的输运系数,如Hall效应系数、电导率、Nernst效应系数和热传导系数的表达式.这些输运系数是由参数q来修正的.当非广延参数q→1时,这些输运系数回到麦克斯韦分布下的形式.
Transport coefficients of plasmas with the power-law distribution are studied using the transport equation and distribution function of plasma with the strong magnetic field.Expressions of these coefficients Hall effect,electric conductivity,Nernst effect,thermoelectric coefficient of the power-law distribution are accurately derived.It is shown that these transport coefficients are mainly modified by the q-parameter.When the parameter q→1,they are reduced to the standard forms of a Maxwell distribution.
