摘　　要：暂现的硬X射线双星系统中,Be星的外流气体结构是一个尚未解决的问题.本文根据Be星的观测和理论,提出了气盘和缓慢加速星风的混合模型,给出了速度结构,计算了X射线光度的变化,解释了A0535+26的许多观测现象.In the transient hard X-ray binaries, the structure of gas outflow from Be stars is not clear. We establish a hybrid model with a disc plus gradually accelerated wind. The velocity structure is presented and the X-ray light curves are calculated. A lot of observational phenomena of A 0535 + 26 can be explained by this model.
