We develop an approximation scheme to construct the spacetime representing a realistic inhomogeneous universe within the framework of general relativity. The scheme allows us to treat the situation where the spacetime has locally nonlinear density contrast, but is homogeneous and isotropic in a global scale. Thus the constructed spacetime should be used for the analysis of the light propagation in our universe which is the theoretical foundation of the observational cosmology. For the application of the present approximation, we shall investigate the propagation of light ray and propose a simple new derivation of the gravitational lens equation which is free from ad hoc assumptions in the conventional treatment and is totally consistent in the framework of general relativity. the validity of the conventional lens equation.

我们开发了一个近似方案，以构建代表一般相对性框架内的现实不均匀宇宙的时空。该方案使我们能够治疗时空在局部非线性密度对比的情况，但在全球范围内是同质和各向同性的。因此，应将构造的时空用于分析我们宇宙中的光传播，这是观察性宇宙学的理论基础。为了应用本近似值，我们将研究光线的传播，并提出对引力镜头方程的简单新推导，该方程在常规处理中没有临时假设，并且在一般相对性的框架中完全一致。常规镜头方程的有效性。
