On the afternoon of December 9th, our group held an experience sharing session on crystal structure analysis in the conference room D601, Hongyi Building.  At the beginning of the conference, Mr. Yu Zhou introduced the principles, methods and related applications of crystal structure analysis.  After that, Biao Meng, a doctoral student, introduced crystallographic principles, data acquisition, software, programming, and structural refinement, and shared his experience in crystal structure analysis.  Through this meeting, the students have a clearer understanding of the crystal structure analysis.
