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.

我们开发了一种近似方案来构造代表广义相对论框架内的现实非均匀宇宙的时空。该方案允许我们处理时空具有局部非线性密度对比但在全局尺度上均匀且各向同性的情况。因此，所构建的时空应该用于分析我们宇宙中的光传播，这是观测宇宙学的理论基础。对于本近似的应用，我们将研究光线的传播，并提出引力透镜方程的一个简单的新推导，该推导不受传统处理中的临时假设的影响，并且与广义相对论的框架完全一致。传统透镜方程的有效性。
