It is shown that when the Casimir force of M-C-S gauge field is calculated, the ghost contribution to the vacuum energy must be taken into consideration in U (1) covariant gauge theory, although the ghost decouples from the gauge.

这表明，即使在U（1）情况下，鬼场与规范场无耦合，在讨论真空的零点能时，鬼场的贡献是必须计入的。只有这样才能抵消非物理分量对真空能量的贡献，获得正确的结果。

In the paper presented here. starting from studying the production of MPs, we explore the theoretical explanation of the reason why the straight filter filtrates the MPs based on the movement of electrons and ions in the straight filter.
