摘要
本文将机器制造专业实用性很强的金属学即钢的热处理这一学科,进行了系统化的研究,并从中提炼出2张网络图。它对理论学习、研究和工程实践有一定的指导意义。
Firstly this paper makes a systematic study on the two subjects of metallography and Iron heat treatment, which are of great practicality in the field of machine building. Then the network relationships between the two disciplines are obtained. The developed network relationships are of great importance to study the two subjects mentioned above.
