摘要

构造了IV型各向异性Bianchi宇宙中具有纯辐射的引力波的非摄动模型。得到了纯辐射的时空度量参数与时空度量参数之间的关系。在给定度规下，光线的轨迹可以作为eikonal方程的解来求得。计算了光信号在引力波中的传播参数。得到了引力波中辐射的延时关系。

Gravitational wave and pure radiation in the Bianchi IV universe

A non-perturbative model of a gravitational wave with pure radiation in an anisotropic Bianchi universe of type IV is constructed. A relationship between the space-time metric parameters and those of the pure radiation is obtained. The trajectories of light rays are found as a solution to the eikonal equation in a given metric. The parameters of light signal propagation in a gravitational wave are calculated. The delay relation for radiation in a gravitational wave is obtained.
