本文用广义相对论计算了引力场对干涉仪的影响。结果表明,如果象通常那样把物理长度定义为固有长度,那么当把干涉仪转动90℃时条纹移动为2.2×10-10(其中取干涉仪臂长1m,光波波长为1μm)。In this work, the effect of Earth's gravitational field on a interferometer is calculated in gereral relativity. The result is that an expected fringe shift, about 10-10, will occur when the interferometer is rotated through 90° if the length of arms are 1 meter and wavelength of light is 1 μm.
