摘要：
A Machian interpretation of Kaluza-Klein gravity is outlined, wherein the fifth coordinate is related to mass. It is shown that with an appropriate form for the metric, the usual law of inertial motion is obtained together with a cosmological variation of particle masses. This variation, however, is slow enough to be compatible with observation. When the 5D theory is reduced to 4D general relativity, a cosmological constant appears which is of acceptable size.
