再论均匀宇宙等离子体中的零频率磁涨落
Zero-frequency magnetic fluctuations in homogeneous cosmic plasma revisited
摘要：
基于涨落耗散定理，重新讨论了非磁化气体等离子体中的磁涨落，并在没有近似的情况下进行了计算。本文的结果与前人基于同一定理的结果相比，在定性和定量上都有不同。特别是，它表明，它是不正确的，光谱强度不随$k_{cut}$敏感地变化。同时，这种强度对等离子体和碰撞频率的依赖关系进行了讨论。
英文摘要：
Magnetic fluctuations in a non-magnetized gaseous plasma is revisited and calculated without approximations, based on the fluctuation-dissipation theorem. It is argued that the present results are qualitative and quantitative different form previous one based on the same theorem. In particular, it is shown that it is not correct that the spectral intensity does not vary sensitively with $k_{cut}$. Also the simultaneous dependence of this intensity on the plasma and on the collisional frequencies are discussed.
