数学作为研究物理的工具,在物理教学中的应用相当普遍,而且在中考或竞赛中有着广泛的应用．数理是相通的．它们在彼此的研究中相互发展与完善．综合运用数学知识,可以正确、迅速地进行有关物理问题的运算．选择正确的数学方法、思路和解题技巧,可以解决一些常规物理方法难以解决的问题,达到事半功倍的效果． As a tool for the study of physics, mathematics is widely used in physics teaching, and has a wide range of applications in the examination or competition. Maths and sciences are connected. They mutually develop and improve in each other’s research. The comprehensive use of mathematical knowledge can correctly and quickly perform operations on physical problems. Choosing the right mathematical methods, ideas and problem-solving techniques can solve some problems that conventional physical methods can’t solve, and achieve a multiplier effect.
