Advanced LIGO和Advanced Virgo对引力波的探测提供了一个机会，可以在传统天文观测和实验室测试无法达到的范围内测试广义相对论。我们提出了四个测试的数据与广义相对论预测的二元黑洞引力波形的一致性。一个测试从数据中减去最佳拟合波形，并检查残差与检测器噪声的一致性。第二个测试检查所观察到的信号的低频和高频部分的一致性。第三个测试检查波形模型中引入的现象学偏差（包括后牛顿系数）是否与0一致。第四个测试限制了由于色散关系的修改而对引力波传播的修改，包括来自大质量引力子的修改。我们目前的结果既为个别事件，也通过结合在一起，特别是从先进的LIGO和先进的处女座，收集在目录GWTC-1的第一次和第二次观测运行强烈的事件获得的结果。我们没有发现任何不一致的数据与广义相对论的预测和改进我们以前提出的组合约束的因素1.1至2.5。特别地，我们将引力子的质量限定为m（g）。
The detection of gravitational waves by Advanced LIGO and Advanced Virgo provides an opportunity to test general relativity in a regime that is inaccessible to traditional astronomical observations and laboratory tests. We present four tests of the consistency of the data with binary black hole gravitational waveforms predicted by general relativity. One test subtracts the best-fit waveform from the data and checks the consistency of the residual with detector noise. The second test checks the consistency of the low- and high-frequency parts of the observed signals. The third test checks that phenomenological deviations introduced in the waveform model (including in the post-Newtonian coefficients) are consistent with 0. The fourth test constrains modifications to the propagation of gravitational waves due to a modified dispersion relation, including that from a massive graviton. We present results both for individual events and also results obtained by combining together particularly strong events from the first and second observing runs of Advanced LIGO and Advanced Virgo, as collected in the catalog GWTC-1. We do not find any inconsistency of the data with the predictions of general relativity and improve our previously presented combined constraints by factors of 1.1 to 2.5. In particular, we bound the mass of the graviton to be m(g)
