The main content studyed in this paper is gravitational waves from OJ287.As a background,we give a simple introduction of the detection of current progress of gravitaonal waves,and look forward to the new progress of gravitational waves in the next decades.The research of waves from OJ287 is importent because OJ287 is very special one of all galaxies.It is known to orbit ,peridic outbursts, and a long history of observation,et al.We also give a simple introduction on the current progress of general relativity experiments because gravitational wave detection is an aspect of GR.This theory of gravity withstood a lot of past and ongoing test.Five classcal experiments proved GR .Hulse-Taylor binary pulsar give 0.2 percent level of verifying the damping effect. The future test of GR is still a topic . Especially,the test in strong gravity field and direct gravitational wave detection are two important aspects.
