PAGE PAGE 27 用推迟引力求解水星进动 汤克云[1][2] 1 中国科学院地质与地球物理研究所 2 中国科学院国家天文台 HYPERLINK mailto:kytang@bao.ac.cn kytang@bao.ac.cn 摘要 本文参照Maxwell电磁理论和Lienard-Weichert推迟势，给出了作任意运动引力源的推迟引力表达式，并在太阳系内修正了牛顿引力定律和开普勒行星三定律。其中最重要的修正是面积定律不再精确成立，即行星绕太阳运动的角动量不再精确守恒，行星的近日点有微小进动。根据推迟引力场计算出水星的进动量与根据爱因斯坦广义相对论计算得到的结果完全相同。这一点十分重要，一方面说明广义相对论不是唯一能够解释水星进动的引力理论； 另一方面，根据我们的推迟引力理论，行星相对于太阳的切向加速运动会产生一附加的切向引力辐射场，本文正是主要根据这切向引力辐射场计算出水星近日点的世纪进动量。根据推迟引力计算出的水星近日点的世纪进动理论值与“观测值”十分接近，这意味着水星近日点的世纪进动正是受太阳的切向引力辐射场作用的结果。换句话说，水星近日点的世纪进动可能正是存在引力辐射场的直接观测证据. 相比而言，Hulse 和 Taylor根据脉冲双星轨道收缩及周期变短得到的是引力波可能存在的间接证据。 Solution on the Precession of Perihelion of Mercury by Retarded Gravitations Keyun Tang[1][2] 1 Institute of Geology and Geophysics, Chinese 2 National Astronomy Observatories, Chinese HYPERLINK mailto:kytang@bao.ac.cn kytang@bao.ac.cn Abstract An un-deformed Coulomb core always exists for the particle with arbitrary motion. The retarded expression of the electromagnetic field for a particle with uniform rectilinear motion has been derived, the retarded expression of the electromagnetic field for a particle with general motion, it equals the particle’s Coulomb core times the retarded transformation vector factor. The retarded gravitational expressions have also been derived. According to the retarded gravitational expressions, I have modified Newton’s gravitational law and Kepler’s laws of planet’s motion, especially the Kepler’s second law: the areas covered by a line drawn from a focus of the ellipse to an orbiting planet in a given length of time are not exactly equal, or the angular momentum is not exactly conserved. According to the retarded gravitational expression and the modified law of planet orbit, I have found that the precession of perihelion of Mercury is about 42.9 arc-seconds per century, it is exactly the same result as Einstein’s general relativity. In my calculation, the precession was caused directly by the additional gravitational radiation field produced by the Sun’s acceleration
