有一次来电，物管说他们小区没有电工，说一幢9层的住宅楼一楼的水泵泵不上水，水池很快就会无水用了，晚上我到达现场，原来是液位继电器坏了，我当时已带上了三极的闸刀开关，在继电器的旁边装上闸刀开关，手动供电给水泵，临时解决了没水用的问题，过后才为他装上液位继电器，又恢复了自动泵水。

According to the existence results of general equilibrium problems and vector equilibrium problems have been studied more and more. Inspired and motivated by these research results, this paper is devoted to study systematically a class of equilibrium problems, which is unify and extension of a large number of known equilibrium problems and variational inequalities problems. The research is carried on from three aspects.Firstly, in finitely continuous topological spaces, we introduce four new types of the system of generalized vector quasi-equilibrium problems, and we derive some existence results of a solution for the system of generalized vector quasi-equilibrium problems via the maximal element theorems in product finitely continuous topological spaces.Secondly, in complete metric spaces, we provide the Ekeland variational principle to equilibrium problems with set-valued maps. And via the Ekeland variational principle, existence results for vector equilibrium problem with set-valued maps and the system of vector equilibrium problem with set-valued maps.
