文档介绍：several group number, then with b ± a, =c,c is is methyl b two vertical box between of accurate size. Per-2~3 measuremen有万人以上的员工，并地理位置分布在大型企业的图书管理系统，图书馆藏书100多万册，每天的借阅量近千册。在手工操作的方式下，图书的编目和借阅的工作量打，准确性低且不易修改维护，读者借书只能到图书馆手工方式查找书目，不能满足借阅需求。需要建设一套网络化的电子图书馆信息系统。
该图书馆管理信息系统效劳对象有两局部人：注册用户和一般读者。一般读者经注册后成为注册用户，注册用户可以在图书馆借阅图书，其他人员只可查阅图书目录，但不能借阅图书。系统同时考虑提供电子读物效劳，目前只提供电子读物的目录查询效劳，不久的将来将提供电子读物全文效劳。用户可通过网络方式访问该图书馆管理信息系统。
several group number, then with b ± a, =c,c is is methyl b two vertical box between of accurate size. Per-2~3 measurement, such as proceeds of c values are equal and equal to the design value, then the vertical installation accurate. For example a, b, and c valueswhile on horizontal vertical errors for measurement, General in iron angle code bit at measurement level points grid errors, specific method is from baseline to methyl vertical box center line distance for a,, to b vertical box distance for b, list can measured
