远星系光信号的红移公式
Formula for red-shift of light signals coming from distant galaxies
摘要：
根据Rev. [1]（physics/0505035）中，我们导出了来自遥远星系的光信号的红移与这些星系离我们的距离以及这些光信号的探测时间之间的关系式。引入了红移系数代替哈勃参数。它随时间而变化，并且始终为正值。它现在的值等于哈勃参数。随着时间从过去走向未来，它永远在增加。导出的公式使我们能够估算出红移系数的现今增长率，这正是“宇宙膨胀加速度”的现今值。
英文摘要：
Relying on the obtained results in Rev.[1](physics/0505035), we derive the formula relating the red-shift of light signals coming from distant galaxies to the distance of these galaxies from us and the time of detecting of these light signals. The red-shift coefficient, instead of the Hubble parameter, is introduced. It varies with time and positive at all times. Its nowadays value equals the Hubble parameter. It increases forever as time is running from the past to the future. The derived formula enables us to estimate the nowadays increasing rate of the red-shift coefficient, which is nothing but the nowadays value of the "acceleration of the expansion of the Universe".
