variable cosmological constant变化的宇宙常数
cosmological constant problem宇宙学常数问题
In the first section of this article, we introduce the gravitational spectral shifts of static gravitational field, and spectral shifts of gravitational fields with mass, or electric charges or cosmological constant.
本文第一部分系统地介绍了引力场的频移效应，如均匀引力场，静态引力场，质量源，电荷源，宇宙常数等等引力场中谱线的频移效应。
