ot exist a priori in nature, but are only artifices used in describing nature, and hence should play no role in the formulation of fundamental physical laws. ? 類似 AB effect——potential 動力學方程 不變性原理決定 對應原理 共動系中:四力、四動量、固有時 四力的時間分量是共動系 LB到實驗室系 dtdpFddpfii?????EEP決定度規(guī)理論 Einstein Equivalence Principle =EEP WEP LLI=Local Lorentz Invariance LPI=Local Position Invariance WEP ? The trajectory of a point mass in a gravitational field depends only on its initial position and velocity, and is independent of its position. –運動學 ——力學 ——》其他物理 LLI –點質量 ——SEP –FFF——preferred——對應原理 LIF LLI=Local Lorentz Invariance ? The oute of any local nongravitational experiment is independent of the velocity of the freelyfalling reference frame
