摘要

摘要我们考虑了在强电场中能够产生电子-正电子对的电子-正电子等离子体。电子对产生和等离子体振荡的动力学取决于电子对分布函数。假设存在费米-狄拉克分布，我们发现相对于忽略等离子体退变性的情况，在小温度下电子对的产生受到抑制，而在小化学势下电子对的产生得到增强。本文讨论了可能出现这种情况的天体物理环境。

On the Influence of Pauli Blocking on Pair Creation in Strong Electric Field

We consider electron–positron plasma in strong electric field capable of creating electron–positron pairs. The dynamics of pair creation and plasma oscillations depends on pair distribution function. Assuming Fermi–Dirac distribution we found that for small temperatures pair creation is suppressed, while for small chemical potentials it is enhanced, with respect to the case when plasma degeneracy is neglected. Astrophysical settings where such conditions may occur are discussed.
