摘　　要：针对渗碳时工件表面碳的传递过程，用质量平衡原理，推导建立了有限差分数值法计算平面、凸柱面、凹柱面和球体四种形状工件渗碳碳浓度分布的差分格式，编制了计算四种形状工件渗碳碳浓度分布的计算机程序。Becauie of the carbon transfer in worke,the general finite differential equation for plate,convex cylinder,concave cylinder and spherical shape works is introduced based on the law of conservation of mass.The computer program used for calculation the earbon concentration profile of the four type shape works is drawn.The carbon concentration profile of these works under the same parameters is discussed.

关 键 词：渗碳计算 程度 有限差分法 碳浓度
