%X We previously revealed that the speed of light in vacuum <i>c</i>, the gravitational constant <i>G</i>, the vacuum permittivity <i>¦Å</i>, and the vacuum permeability <i>¦Ì</i> can be defined by the temperature <i>T</i> (or the expected average frequency <i>f</i>) of cosmic microwave background (CMB) radiation. Given that CMB is continuously cooling, that is, <i>T</i> is continuously decreasing, we proposed that the above ¡°constants¡± are variable and their values at some space-time with CMB temperature <i>T</i> (<i>c<sub>T</sub></i>, <i>G<sub>T</sub></i>, <i>¦Å<sub>T</sub></i>, and <i>¦Ì<sub>T</sub></i>) can be described using their values (<i>c</i><sub>0</sub>, <i>G</i><sub>0</sub>, <i>¦Å</i><sub>0</sub>, and <i>¦Ì</i><sub>0</sub>) and the temperature (<i>T</i><sub>0</sub>) of CMB at present space-time. Based on the above observation, a number of physical equations related with these constants are re-described in this study, including relativity equation, mass-energy equation, and Maxwell¡¯s equations, etc.
