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.

Emulsion, Emulsion Layer:(1) Broadly, any light sensitive photographic material consisting of a gelatin emulsion containing silver halides together with the base and any other layers or ingredients that may be required to produce a film having desirable mechanical and photographic properties.

广义上说，是指任何光敏感性的摄影材料，它包括含卤化银的明胶乳剂和片基以及其它层或组分结合在一起，后者可能是胶片具有要求的机械和摄影性能所需要的。2）在讨论摄影胶片的构造时，乳剂层是任何一种包含光敏感性的卤化银颗粒的涂层，与背层，片基，黏结层或滤层有所区别。

Its freight business is a chronic lossmaker, hobbled by rigid labour practices that mean it cannot compete with rivals such as EWS and Veolia which are already operating in France.
