Firstly the concepts of MP-filters and prime filter in NML algebras are introduced, and then topological structure of the set of all prime filters of NML algebras are discussed.

首先在NML代数上引入MP -滤子与素滤子的概念，进而讨论了滤子和素滤子的基本性质，最后在全体素滤子之集上建立了拓扑结构。

Indeed, he believes he and every other country's Europe minister should be formally linked to the head of government, spending half his or her time in Brussels and acting as a sort of prime ministerial filter.
