我们用类星体和伽玛暴数据检验了宇宙学原理。相比Ia超新星数据，类星体和伽玛暴数据有更大的红移范围。类星体和伽玛暴数据的分布比Ia超新星数据的分布更均匀，尤其是伽玛暴数据。伽玛暴数据的分布近似均匀。2015年类星体对各向异性信号的限制非常好，但是对物质密度的限制比较弱。2020年类星体数据给出的各向异性信号非常弱。我们用红移分层的方法分析了2020年类星体数据，发现越高红移的类星体对偶极幅值的限制越强。伽玛暴给出的各向异性信号也非常弱。我们发现伽玛暴数据可以减弱分布不均匀的数据给出的各向异性信号。

We test the cosmological principle with quasar and GRB samples. Compared with the SNe Ia sample, the quasar and GRB samples have a larger redshift range. The distributions of the quasar and GRB samples are more uniform than that of the SNe Ia sample, especially the GRB sample. The distributions of GRB samples in the sky are nearly homogeneous. The anisotropic signal is well-constrained by the 2015 quasar compilation, but the matter density and its uncertainty are larger compared to the estimates given by the CMB and SNe Ia. The anisotropic signal from the 2020 quasar compilation is very weak. We analyze the 2020 quasar compilation with the redshift tomographic method and find that quasars at a higher redshift range may provide more detailed information about the dipole amplitude. The anisotropic signal from the GRB sample is also very weak. We find the GRB sample can reduce the anisotropic signal from inhomogeneous samples.
