恒星距离的计算方法

The method of calculating the distance of a star

摘要: 光速不变原理是相对论的基础，但为什么不变？假设光子为了保持速度恒定能够自动衰减它的能量，利用这个假设推导出了红移的计算方法：多普勒红移zv=v/(c-v),引力红移zg=GM/(rc2-GM)，距离红移zd= exp(L/4669)-1，并指出了多普勒公式中的错误和根据广义相对论推导出的引力红移公式的瑕疵。利用普森公式、距离与红移的关系及两个Ia型超新星参数，求出了关联系数a及星际消光系数b。用两种方法计算出了155个恒星的距离并比较了它们的差别。证明了光子在星际中传播时能量衰减很小，但它却是引起红移的主要原因；星际的绝对消光也很小，但忽略它会引起很大的误差。最后，解释了引起计算误差的原因，提出了测量关联系数的方法，说明了哈勃常数是距离的函数，分析了类星体的发光原因,并估算了类星体的距离和半径。

Abstract: The principle of constant light speed is the basis of relativity, but why not change? It is assumed that photons can automatically attenuate their energy in order to maintain constant velocity, by using this hypothesis, the calculation methods of red shift are deduced:DopplerredshiftzD=v/(c-v),gravitationalredshiftzg=GM/(rc2-GM)，distance red shift zd= exp(L/4669)-1，and points out the errors in the Doppler formula and the flaws of the gravitational red shift formula deduced from the general relativity. Using M.R.Pogson formula, and the relationship between dis-tance, and the parameters of two Ia supernovae, the extinction coefficient and the correlation coefficient are obtained. The distances of the 155 stars are calculated in two way sand their differences are compared. It is proved that the energy attenuation of photon propagation in interstellar space is very small, but it is the main cause of red shift, the absolute extinction of interstellar dust is also very small, but it will cause great computational error when ignoring it. Finally, the reasons for calculation errors are explained, the method for measuring correlation coefficients is proposed, the Hubble constant as a function of distanceis described, the luminous reasons of quasars are analyzed, the distances and radii of quasars are estimated.
