本文主要致力于黑X射线双星光变曲线以及周期性特征的研究。黑洞是经过恒星引力塌缩而形成的一种质量较大的致密天体，几乎所有的黑洞系统是X射线新星。

This paper is contributed to the study of the light curve and periodicity of the black hole X-ray binary Cyg X-1.Black hole is the high-mass compact object , which is result of the gravity collapse of the star and most of the black hole system is X-ray nova .

同时，为了进一步了解黑洞的物理过程，通过研究黑洞态以及其光变曲线的周期性变化一直以来是一种十分重要的方法。

Moreover , it is a very important method with study black hole states and the periodicity of the light curve to study their physical process .
