The detection of gravitational waves (GW) is a major achievement in physics and astrophysics. Up to now, more than 30 GW events resulting from the merger of compact celestial bodies have been observed by LIGO and VIRGO. Because electromagnetic radiation is the main method for studying astrophysical processes, whether physics can be combined with astronomy depends on whether the corresponding body of gravitational wave events can be found on electromagnetic radiation. Unfortunately, only the electromagnetic counterparts of the twin neutron star merger are currently seen. In gravitational wave astronomy, a very important subject is: Is it possible to generate electromagnetic radiation when the two black holes’ merge? In this essay, the dynamic process of the gas disk surrounding the binary black hole is studied through numerical simulation, and the long-term evolution process of these gases on the cosmological time scale is studied at the same time. The evolution process of the gas disk of the ring binary black hole can be obtained, which provides a theoretical limit on whether the electromagnetic counterpart of the merger of the binary black hole can be seen in the future.

引力波（GW）的探测是物理学和天体物理学的一项重大成就。迄今为止，LIGO和VIRGO已观测到超过30GW的致密天体合并事件。由于电磁辐射是研究天体物理过程的主要方法，物理学能否与天文学相结合，取决于能否在电磁辐射上找到相应的引力波事件体。不幸的是，目前只能看到双中子星合并的电磁对应物。在引力波天文学中，一个非常重要的课题是：两个黑洞合并时是否可能产生电磁辐射？本文通过数值模拟研究了双星黑洞周围气体盘的动力学过程，同时研究了这些气体在宇宙时间尺度上的长期演化过程。可以得到环状双黑洞气盘的演化过程，为未来能否看到双黑洞并合的电磁对应物提供了理论极限。
