控样在钢铁分析中是必不可少的,且数量又较多,在快速分析中,靠操作人员寻找合适的控样较费时间,用计算机管理控样是缩短分析周期的一种方法。用计算机管理控样是利用文件管理系统对控样进行存储,检索。使用时只需把钢种的名字输入计算机,打印机很快就会打出这种钢所需要的控样号,存放地点,应选用那个合金号进行分析,以及用于标准化的样块号等。当控样数量较多时,用计算机查找比人工查表要快好多倍,且不会出现差错。因为控样数量不算特别多,所以程序采用顺序检索。信息是以随机文件的形式存入外存储器。
Controlled samples are indispensable in the analysis of steel, and the quantity is more. In rapid analysis, it takes more time for the operators to find suitable samples to control the samples. It is a method to shorten the analysis period by computerized sample control. Computer-controlled sample control is the use of file management system for sample storage, retrieval. Just use the name of the steel input into the computer, the printer will soon be required for the production of such steel control sample number, storage location, the alloy should be used for analysis, as well as for the standardization of the sample number and so on. When the number of control samples is large, it is many times faster to find the computer than the manual look-up table, and there is no error. Because the number of sample control is not particularly large, so the program uses sequential retrieval. The information is stored in external memory as a random file.
