摘　　要：复射线作为一种有效的数值计算方法得到了较广泛的研究和应用。但 ,复射线的复源点模型脱离物理现实。而将复射线表示为一平面口径的辐射场 ,从而为复射线的发生提供了一种现实的物理模型——平面口径辐射。在此基础上 ,对复射线的一些相关的问题进行了比较深入的讨论。As an efficient numerical algorithm for propagation a wave through a complex medium, complex ray technique has been studied and applied extensively. However, the complex source point model of a complex ray is not a realistic physical model, because a complex source point can not be realized. It presents a plane aperture radiation of a complex ray field, and provides a new realistic physical model —— plane aperture radiation model. Based on this model, some basic concept of a complex ray are discussed.
