摘　　要：从可压缩连续介质角度出发,给出一种可以在空间二级准确度上兼容的相对论然而又允许超光速介质运动存在的数学描述.先给出无粘不可压缩流动的Euler方程可以改写成和电磁场方程相同的表达形式:在空间二阶准确度的意义上来说,不可压缩流+相对论近似等于可压缩流,它们都是和现在的实验结果相融的;给出可压缩流动的广义相对论.这也说明协变不变原理不过是可压缩流动的一种近似处理方法.新模型可以解释索么菲(A.Sommerfeld)提出的粒子在超过光速后减小能量反而加速的现象.The super-light speed research is presented from the aspect of continuum medium, and the mathematics description of medium is deduced. This description allows the existence of super-light speed phenomena,but it is also compatible with relativity theory. From the similarity between Navier-Stokes equation and Maxwell equation,which lake one corresponds equation from whole 4 equations,an analysis is deduced,depend using the concept of relax effect of non-Newtonian viscose Fluid,the last missing equation is constructed. Through deduce,a concept to consider the Maxwell equation and NS equation as similar object is glvenbut in different viewpoint. On this background the equivalence between compressible wave equation and incompressible wave equation with Lorenz is discussed. The relation of medium and energy of relativity theory is given by the new theory,and the rule element of general relativity in compressible flow if also given.
