在常规教学中,分析驻波所用的方法与分析波的干涉的方法不同,以致有些学生误认为两者是没有关联的独立现象.本文认为可以用波的干涉的观点讲授驻波现象,说明驻波就是特殊条件下的干涉现象,从而加深学生对驻波的干涉特性和物理图像的理解.
在常規教學中,分析駐波所用的方法與分析波的榦涉的方法不同,以緻有些學生誤認為兩者是沒有關聯的獨立現象.本文認為可以用波的榦涉的觀點講授駐波現象,說明駐波就是特殊條件下的榦涉現象,從而加深學生對駐波的榦涉特性和物理圖像的理解.

Commonly,the analysis methods for the wave interference and the standing wave are difference so that some stu-dents think there is no link between them. This paper analyzes the standing wave in the view of interference and show that the standing wave is a special phenomenon of the interference. It promotes students' understanding of the interference char-acteristics and the physical image of the standing wave.
