摘要
静止的电荷在其周围空间产生电场,具有质量的物质在其周围空间产生引力场。2种场所满足的微分方程形式相同。电荷的运动产生磁场,依据引力场与电场的相似性,物质的运动应该产生一种新的物理场,即“质流场”。引力场与质流场的关系正如电场与磁场的关系。时变质流场感应出引力场,时变引力场感应出质流场。给出了这2种场所满足的微分方程组,其形式与电磁场理论中的麦克斯韦方程形式一样,从而建立了一套完整的、物理意义明确的关于引力场与质流场的基本理论。从该方程组出发,推导了引力场满足的波动方程,其波速度为光速,与爱因斯坦引力场方程的关于引力波的预言吻合。正是引力场与质流场相互感应导致引力波。引力场方程组在时不变的稳态情况下退化为牛顿万有引力定律。
Static charge produces an electric field around its space,materials with mass produce a gravity field around the space.Differential equations for these 2 fields are the same.The motion of charge creates a magnetic field,based on the similarities of the gravitational field and electric field,the motion of materials should produce a new physical field,that is a “mass flow field”.The relation between mass flow field and gravitational field is similar with that of an electric field and magnetic field.A time varying mass flow field induces a gravitational field.A time varying gravitational field induces a mass flow field.The differential equation group for these 2 fields is given,its type is similar with that of Maxwell's equation in electric field theory.Therefore a complete set of basic theory with clarified physical meanings is concerning the gravitational field and mass flow field.Starting from the aspects of equation group,a wave equation for the gravitational field is derived.Its wave speed is a light speed.It is coincident with the prediction on the gravitational wave in Einstein's equation of gravitational field.It is the gravitational field and mass flow field that the gravitational wave is produced by the induction each other.Under the condition without time varying,the equation group of gravitational field is deduced to Newton's law of universal gravitation.
