摘要
本文指出,一个de-Sitter型的强引力度规,在引入曲率标量二次项修正后,可保持度规形式不变。但是,由于二次项的作用。等价于使强引力耦合系数G_f相应减小,这说明二次项的修正可以导致一个合理的强引力而避免奇异性。
In this paper, we introduce a square term of the curvature scale R in the strong gravity
Lagrange with de-Sitter form, the square term has made the coupling coefficient of strong
gravity G_f to decrease, it can get a reasonable strong gravity model and avoid singularity.
