时空是弯曲的
Is space-time curved
摘要：
时空是否弯曲？判断这一点的实验标准是：（1）三个经典相对论实验的结果在本质上是有利于狭义相对论引力理论（以平直时空为基础）的。但它们对广义相对论是不利的。(2)在重力探测器B实验中：由狭义相对论引力理论推导出的轨道效应的陀螺进动率=（2/3）* 由广义相对论推导出的大地效应的进动率，由狭义相对论引力理论导出的地球自转效应的岁差率=（3/2）* cos（φ）的平方 * 坐标系的岁差率-从广义相对论推导出的拖曳效应，其中（phi）是陀螺仪角速度在赤道平面上的投影与轨道平面法线之间的夹角。如果实验值与狭义相对论引力理论的预言值一致，则时空是平坦的。
英文摘要：
Whether the space-time is curved or not? The experimental criterions to judge this point are: (1) The results of three classical relativistic experiments in essence are favorable to the special relativistic gravitational theory (base in the flat space-time). However they are unfavorable to the general relativity. (2) In the Gravity Probe-B experiment: the gyroscope precession rate of the orbital effect deduced from the special relativistic gravitational theory =(2/3)* the precession rate of geodetic effect deduced from the general relativity, the precession rate of the earth rotation effect deduced from the special relativistic gravitational theory =(3/2)* the square of cos(phi)* the precession rate of the frame-dragging effect deduced from the general relativity, where (phi) is the angle between the projection of gyroscope angular velocity in the equatorial plane and the normal line of orbital plane. If the experimental values are identical with the predictive values deduced from the special relativistic gravitational theory, then the space-time is flat.
