摘　　要：本文导出了描述气体渗碳过程中工件表面碳浓度随处理时间变化的数学表达式，并通过文献中提供的实测数据进行了验证。In this paper, the kinetics of increase in surface carbon concentration during gas carburization was investigated, and a new equation calculating surface carbon concentration was introduced. The results of simulation have a good agreement with the measured data in literatures.
