灰铸铁是目前广泛使用的铸造材料。采用计算机辅助金相检测的办法对灰铸铁进行快速定量金相分析，在研究和生产中均具有重要意义。研制的检测系统能够对按国标要求的检测项目给出不受人为影响的数值结果。
Gray cast iron is currently widely used as casting material. The use of computer-aided metallographic detection of gray cast iron for rapid quantitative metallographic analysis, both in research and production are of great significance. Development of the detection system can be required by the national standard test items are given uninfluenced numerical results.
