standard cavity

The hydrogen maser is the most stable frequency standard generally available today for all but the shortest measuring times. For long measuring times of 10 4s or longer, its performance typically deteriorates due to frequency drift of high Q resonant cavity.

氢脉泽是至今为止除极短时间测量间隔之外最稳定的频率标准，对于104s或更长的测量时间间隔，它的性能由于高Q值谐振腔而引起频率漂移而变坏。
