标题： Space-Time Variation of Physical Constants and the Equivalence Principle

摘要： 物理参数如电磁精细结构常数和牛顿的G的局域依赖性会产生物体加速度，这会违反自由下落率的普遍性，可通过实验室和空间实验进行测试。 这些相同参数的理论相关宇宙学时间变化也受到例如月球激光测距等实验的约束，这些时间变化会产生相对于优先宇宙学框架的物体加速度。 显示英文摘要

摘要： Location dependence of physical parameters such as the electromagnetic fine structure constant and Newton's G produce body accelerations which violate universality of free fall rates testable with laboratory and space experiments. Theoretically related cosmological time variation of these same parameters are also constrained by experiments such as lunar laser ranging, and these time variations produce accelerations of bodies relative to a preferred cosmological frame.
