Abstract:There are several common problems in the use and maintenance of large valuable experimental instruments in colleges and universities: the lack of responsibility consciousness of users, the low input of instrument maintenance cost, the failure of personnel technology, the backwardness of maintenance technology, the lack of daily maintenance concept and so on, which seriously shorten the service life of large precious experimental instruments. Therefore, it is necessary to strengthen the fine management of large valuable experimental instruments from the point of view of establishing and perfecting the management system of large precious experimental instruments, improving the technical level of users and solving the problem of emphasizing procurement and light management, so as to effectively prolong the service life of large valuable experimental instruments.
