厚透镜成象的基点及物象公式的简化推导

A Simple Derive of Formula about Cardinal Point and The Iimage of The Thick Lens

利用折射球面成象的牛顿公式及光学间隔概念,更加简洁地得出了有关厚透镜成象的基点及物象公式.

With used Newton's image formula of spherical refraction and the optical spacing term, the formula about cardinal point and image of the thick lens is derived with simpler and more natural way.
