摘要：

We investigate the effects of gravitational lensing by large-scale structure on temperature fluctuations in cosmic microwave background radiation. A simple expression is determined for the perturbed correlation function, which is valid for any angular scale. We conclude that the effect is too small to be observed, contrary to recent claims.
