Especially the accurate modeling of the transition curve of dedendum, which ensures the accuracy of bending fatiguestrength of the tooth root by the finite element analysis.
特别是对齿根过渡曲线白勺准确建模，保证了对齿根弯曲疲劳强度停止有限元分析白勺准确性。

On the basis of testing process at the fatiguestrength, and combining -3s-s-n curve, we clearly explain reliability meaning about fatiguestrength in infinite life.
