从经典到现代以太漂移实验：首选框架的窄窗口
From classical to modern ether-drift experiments: the narrow window for a preferred frame
摘要：
现代以太漂移实验通过测量两个腔稳定激光器的相对频率的差异Δ v来寻找优选的框架，在设备的局部旋转或地球旋转的情况下。如果在经典的以太漂移实验中观察到的小偏差不仅仅是仪器的伪像，那么通过用介电气体介质（例如空气）代替谐振腔中的高真空，典型的测量Δν \sim 1 Hz应该会增加几个数量级。这一预测与He-Ne脉泽原始实验中观察到的几kHz的特征调制是一致的。然而，如果这种增强不能被新的和更精确的数据所证实，则可以明确地排除优选帧的存在。
英文摘要：
Modern ether-drift experiments look for a preferred frame by measuring the difference Δνin the relative frequencies of two cavity-stabilized lasers, upon local rotations of the apparatus or under the Earth's rotation. If the small deviations observed in the classical ether-drift experiments were not mere instrumental artifacts, by replacing the high vacuum in the resonating cavities with a dielectric gaseous medium (e.g. air), the typical measured Δν\sim 1 Hz should increase by orders of magnitude. This prediction is consistent with the characteristic modulation of a few kHz observed in the original experiment with He-Ne masers. However, if such enhancement would not be confirmed by new and more precise data, the existence of a preferred frame can be definitely ruled out.
