我们学习或者研究物理学,必须掌握物理学的基本规律,要使学习或研究更加有效,还必须掌握物理学的基本结构、基本方法,学会物理学的思维方法,但是只做到这一点是不行的,还应该能够举一反三.2013年全国高考江苏卷第3题,以破缺的圆环——1/4带电圆环为问题情景,打破了常规的命题情景——点电荷模型和对称性模型.该题可考查学生等效建模思想、微元思想、叠加等思想以及灵活运用定性分析法、数学方法、
To study or study physics, we must master the basic laws of physics. If we want to make learning or research more effective, we must also master the basic structure and basic methods of physics and learn the methods of thinking of physics. However, this can not be done , But also should be able to give top points to all. The 2013 National Entrance Examination Jiangsu Volume 3, broken ring - 1/4 charged ring as the problem scenario, breaking the conventional proposition scenarios - point charge model and symmetry model This question can examine students’ equivalent modeling thoughts, micro-thinking, superposition and other ideas as well as the flexible use of qualitative analysis, mathematical methods,
