数学和物理联系非常广泛,数学教材中的一些数学题就来源于物理,特别是在反比例函数一部分内容中体现更为突出.我认为数理结合的意义有两个:一是体现数学与实际相联系,二是体现学科之间的交叉综合.但有些数学教材中,由于数理结合问题出现过早,相应的物理知识的学习没跟上,对教师而言,讲解起来 Mathematical and physical connections are very extensive, and some math problems in mathematics textbooks come from physics, especially in the part of inverse proportion functions. I think there are two meanings in the combination of mathematics and theory: First, it is to embody the relationship between mathematics and reality. The second is to reflect the interdisciplinary integration. However, in some mathematics textbooks, the combination of mathematics and theory has emerged prematurely and the corresponding physical knowledge has not kept pace with the teacher.
