在机械制造业中自1980年以来陆续制定了一些新的国家标准,这些标准大多是以ISO标准为基础制定的,内容多而新,企业在使用中普遍感到查表与计算工作量大,容易发生差错。有人将这些表格及计算过程编成程序输入微机中,由于数据太多和计算工作繁复,他们选用了IBM—PC机,这种微机用磁盘存储,容量没有问题,但是在推广应用上却遇到了问题。首先这种微机价格较贵,不能普及到每个科室,查一个数或计算一个项目要到计算 In the machinery manufacturing industry, some new national standards have been formulated successively since 1980. Most of these standards are based on the ISO standards. They are new in content and are widely used in the fields of enterprises. An error occurred. Someone put these forms and calculation process into the program into the computer, due to too much data and computational complexity, they use the IBM-PC, this computer with disk storage, no problem with the capacity, but in the promotion of applications have encountered problem. First of all, this computer is more expensive, not universal access to each department, check a number or calculate an item to calculate
