摘要
本文讨论了Ｂｅｔａ算子导数的Ｌｐ逼近问题，利用光滑模与Ｋ─泛函之间的等价关系，在证明了Ｂｅｔａ算子可交换性的基础上，给出了算子导数的Ｌｐ逼近的特征刻划。
This paper deals with the Paraxial analysis of modern type mechanically compensated zoom lenses. With the help of Gaussisn Brackets, a paraxial study of the zoom lenses which are composed of 2, 3 and n independently movable components is presented.
