The purplose of this paper is to infer the new analytic formula of complex amplitude of an axial symmetrical diffraction wave field; besides, to grant a physical annotation and to discuss harmony for oneself in view of this analytic formula.

• 本文导出轴对称衍射波场复振幅分布的一种新形式,尝试性地给出一种物理诠释,将这一分布应用到几种典型的衍射波场区域表现出较好的自洽性。
