Power users shall pay electricity fees on time according to the electricity price examined and approved by the state and the records of electricity meters , and shall provide convenience and assistance to the safety inspectors , meter readers , and fee collectors in fulfilling their duties in conformity with legal provisions 用户应当按照国家核准的电价和用电计量装置的记录，按时交纳电费；对供电企业查电人员和抄表收费人员依法履行职责，应当提供方便。
Naturally , further layers exist in between , like the virtual file system layer and the actual memory management routines , but regarding managing structured information accessible to users , it makes sense for power users to peer into file system internals and get just a sulfurous whiff of the kernel s infernal recesses 当然，在这两者之间还存在很多层，如虚拟文件系统( vfs )层和实际存储管理例程，但是就管理用户可用的结构化信息而言，超级用户看一下系统内部，并对内核的最深处有一些了解是很有意义的。
However the execution situation of the experiment and training of microprocessor relay protection of the colleges and universities at home and vast power users lags obviously behind the situation of popularization and application of microprocessor relay protection in the project site . there are scarce kinds of microprocessor relay protection experimental or training equipment in existence whose function is single , price is expensive , bulk is huge , and practicability is poor 但是国内各院校和广大电力用户对微机保护实验和培训的实施情况明显滞后于微机保护在现场的推广应用，现有的微机保护实验或培训装置种类很少，功能单一，价格昂贵，体积庞大，实用性不强。
