对透镜成像原理及成像特点的掌握和应用是解决许多光学问题的关键.由于成像情况多,特点不一,成像规律难记易忘,并且单纯通过实验现象,容易理解不透.若是与物理学的作图法联系起来,则能促进我们对透镜成像原理的把握,有助于加深理解和记忆. The key to solving many optical problems is to grasp and apply the imaging principle and imaging features of the lens.Due to the many imaging conditions and different characteristics, the imaging rules are hard to remember and easy to understand through the experimental phenomena, Of the mapping method, it can promote our understanding of the principle of lens imaging, help to deepen understanding and memory.
