过去,我們的全部技术档案和技术資料都是采用大流水編号的排架方法。这种方法虽然有文件位置固定,沒有倒架現象等优点,在我們不熟悉技术档案工作的情况下,对完成历年的設計任务。起了一定作用。但随着勘測設計工作全面发展,各种科学技术档案和技术资料越积越多,因此,大流水号的排架方法,就不能适应形势发 In the past, all of our technical files and technical information are based on the use of big numbers. Although this method has the advantages of fixed file location and no upside down phenomenon, we are able to accomplish the design tasks of the calendar year without being familiar with the technical file work.
