摘要
本文从分析时间、空间及运动的测量机理出发建立时间和空间的理论。导出了建立在电磁信号单向传递的相对性原理基础上的时空对称的新加里略变换 ,并证明了麦克斯韦方程对新加里略变换的协变性。阐明了光速不变原理和洛伦兹变换的物理意义和实质。引进了两套自洽的速度定义 ,对应两套自洽的变换。讨论了超光速运动的测量机制 ,相对运动特征值出现负值是超光速运动的特征 。
The theory of space and time is established on the basis of analysis of the measurement mechanism of space,time and motion.New Galileo transformation with space and time symmetry is derived on the basis of the principle of relativity of one way electromagnetic signal propagation with consideration of the extra time delay caused by the limited speed of signal propagation.Covariance of the Maxwell 's equation is proved with respect to the new Galileo transformation with space and time symmetry.An interpretation is given to the physical meaning and essence of Einstein's principle of the constancy of the speed of light and Lorentz transformation.Two sets of self consistent definitions of velocity are introduced,which correspond two sets of self consistent transformation.The measurement mechanism of motion with speed exceeding the speed of light is discussed.The negative value of the characteristic value of relative motion is a characteristic of motion with speed exceeding the speed of light,which corresponds negative mass and negative energy.New Galileo transformation and Lorentz transformation with respect to motion with speed exceeding the speed of light are derived.The traditional interpretations and conclusions,extrapolated from the Lorentz factor 1-V 2C 2 ,should be re examined.
