摘要:We estimate the extremal length of a simple closed curve along the conformal grafting ray determined by a rational lamination. Furthermore, utilizing the  estimation formula of the extremal length, we calculate the endpoint of this conformal grafting ray on the Gardiner-Masur boundary. Finally, we obtain a formula of the limit distance between two conformal grafting rays with the Teichmüller metric.
