查询词典 mathematical model

In this thesis a mathematical model referring to the relationship between the case depth and carbon distribution by using a nonlinear regression. The electromagnetic characteristics in carburized materials were discussed. Results show that inductivity and magnetic inductivity depend on the carbon concentration in carburized layer. A relationship model between the electric, magnetic inductivity and carbon concentration was built.
