摘要
通过利用主点(节点)的特性,用物距——像距法测量透镜组的基点,克服了用平行光入射透镜组时,由于透镜组合的多样性以及仪器等原因,使得实验受到限制,从而无法进行的困难。
Using the properties of the main point （node） , with the object distance-image distance method measuring the cardinal point of the lens combination, to overcome the use of parallel light incidence lens combination, because of the diversity of the lens combination and instrument and other reasons, makes laboratory be limited, which can not be difficult.
