数学知识和方法的运用是处理物理学问题的重要手段之一,它要求我们根据研究对象物理特征,综合地运用数学知识对研究对象进行描述、计算和推导,从而揭示出物理对象的运动规律.普通高等学校招生全国统一考试(物理)也将“应用数学知识处理物理问题的能力”作为能力考查的“五大主力”之一,足见该方面知识的重要. The application of mathematical knowledge and method is one of the important means to deal with the physics problem. It requires us to describe, calculate and deduce the research object synthetically according to the physical characteristics of the research object, revealing the movement law of the physical object. The National Unification Examination for Enrolled Colleges and Universities (Physical Education) will also be “the ability to apply mathematical knowledge to deal with physical problems” as one of the “five main forces” of ability test, which shows the importance of knowledge in this respect.
