| 摘 要： | 大学物理中,计算等厚干涉形成的条纹数目时,经常采用计算相邻两明(暗)纹的间隔数,然后条纹间隔数即等于条纹数。多年的教学实践表明采用上述方法计算明、暗条纹数,物理意义不很清晰,特别是学生不易掌握。文中提出了采用加强和减弱条件计算明、暗条纹数的方法,该方法意义明确,学生更易于接受。

| Abstract: | In college physics teaching, when we calculate the number of fringes formed by equal thickness interference, we often adopt the method of calculating the number of intervals of two adjacent bright （dark） lines, then the number of intervals of lines is equal to the number of fringes. After many years of teaching physics, I think that the above method of calculating the number of bright （dark） hnes is not very clear in physical meaning,especially it is difficult for students to master this method. This paper presents the method of calculation of bright, dark fringes by strengthening and weakening the conditions, This method is clear and it＇s more easily for students to accept it. |
