MATLAB可视化在扭摆法测量刚体转动惯量中的应用

将MATLAB应用于物理实验教学中,通过编程绘制扭摆法测量刚体转动惯量的实验过程动画,将抽象复杂的实验过程具象化,有利于讲解过程中辅助学生理解;将实验数据导入工具包Curve Fitting Tool进行数据处理,绘制函数图像得出物体转动惯量的数据结论,不仅能够得到精确的实验数据,更能加深学生对于实验原理及各参数之间关系的理解.随着各类信息化编程软件发展,实验过程可视化、实验数据精确化处理成为了课堂教学的重要辅助,提升实验教学的趣味性并且锻炼学生的物理感性思维.     

Tsallis Mapping in Growing Complex Networks with Fitness

We introduce Tsallis mapping in Bianconi-Barab'asi (B-B) fitness model of growing networks.This mapping addresses the dynamical behavior of the fitness model within the framework of nonextensive statistics mechanics,which is characterized by a dimensionless nonextensivity parameter q.It is found that this new phenomenological parameter plays an important role in the evolution of networks:the underlying evolving networks may undergo a different phases depending on the q exponents,comparing to the original B-B fitness model,and the corresponding critical transition temperature T C is also identified.
