frequency drift

基本解釋

The limited sensitivity of present pulsar surveys and the greater frequency drift make the more distant pulsars difficult to observe.
目前脈沖星普查的有限探測靈敏度和大的頻率漂移，使我們難以觀測到更遙遠(yuǎn)的脈沖星。
This approach the problem of conquers phase excursion and frequency drift that anciently adopts fixed frequency filter and its frame is simple.
這種方法克服了以往采用固定頻率濾波器帶來的相移和頻率漂移問題，而且結(jié)構(gòu)簡單。
Analyze the frequency shift of the oscillator which caused by the circuit elements or the transistor parameters and the relationship between the parameter and the frequency drift.
分析石英振蕩器因電路元件或晶體管參量變化所引起的頻率變化，就參量變化與頻率漂移彼此之間的關(guān)系作了計(jì)算。
