摘要：

We demonstrate the observational viability of having an exactly massless dilaton field couple with gravitational strength to most matter in the Universe. This is done by constructing a generalized Jordan-Brans-Dicke model in which the scalar couples with different strengths to visible and to conjectured eedarkee matter. In this model, improved a measurements may provide nontrivial bounds on the coupling constants of the dilaton to matter. © 1990 The American Physical Society.
