现行“高中物理教学大纲”及“中学物理竞赛内容要求”都已明确:不要求使用微积分解题,对数学基础的要求局限在初等数学的范畴。这是完全符合中学生所具备的物理知识和数学知识的实际的,但是某些连续变力问题,曲线或曲面的引力场、静电场问题,中学生仍可有所作为。在近年来出现的某些较高档次的题目,就仅仅是借助微积分的一些最基本的思想及处理方法突破难点,这就是习惯所称的“微元法。”由于这类题目已数次出现在“全国中学生物理竞赛”考卷上,因此,“微元法”应列为物理竞赛辅导课中的一项教学内容。在不了解微积分知识的情况下要掌握“微 The current ”high school physics syllabus“ and ”secondary physics content requirements “ have been made clear: the use of calculus to solve problems is not required, and the requirements for mathematics are limited to the scope of elementary mathematics. This is in full compliance with the physical knowledge and mathematics knowledge that middle school students possess. However, some students can still make a difference in the problem of continuous variable force, gravitational field or electrostatic field of curves or surfaces. Some of the higher-grade topics that have emerged in recent years are merely using the most basic ideas and processing methods of calculus to break through the difficulties. This is what is customarily called the ”micro-element method.“ Several times appeared on the ”National High School Students Physics Competition“ examination paper. Therefore, the ”Weiyuan Method“ should be listed as a teaching content in the physical training tutorial. Do not understand the knowledge of calculus to master ”micro
