摘要：

Tensor-scalar theories of gravity axe shown to generically contain an attractor mechanism toward general relativity, with the redshift at the beginning of the matter-dominated era providing the measure for the present level of deviation from general relativity. Quantitative estimates for the post-Newtonian parameters gamma - 1, beta - 1, and G/G are given, which give greater significance to future improvements of solar-system gravitational tests.
