摘要
用有限温度场论方法，研究了真空极化的温度和密度效应及背景介质的电磁性质，严格计算了真空极化的有限温度、密度修正和热背景介质的介电常数与磁导率，给出了对任何温度和任何密度都适用的严格的解析表达式。
The finite temperature and density effect of vacuum polarization as well as the electromagnetic proptrty of thermal background medium are investigated. The vacuum polarization tensor the electrical permittivity and magnetic permeability are calculated strictly, and the strictly anlytical expression is presented which is applicable to all temperature and various density.
