Principles for adaptive high speed precise frequency measurement 自適應(yīng)高速精密測(cè)頻原理
Optimized to provide fast , precise frequency measurements with 它提供了與agilent 53131a和
A way to realize precise frequency measure by single chip microcomputer 用單片機(jī)實(shí)現(xiàn)精密測(cè)頻的方法
The precise frequency will be determined by the hkmas risk assessment of the institution 至于實(shí)際的審查次數(shù),金融管理局會(huì)視乎其對(duì)有關(guān)機(jī)構(gòu)的風(fēng)險(xiǎn)評(píng)估而決定。
Each satellite contains four " atomic clocks , " which vibrate at a precise frequency , according to the laws of the quantum theory 每顆衛(wèi)星都裝有4個(gè)“原子鐘” ,它們根據(jù)量子理論法則,以精確的頻率振動(dòng)。
By closely monitoring the precise frequencies of the spectrum that were lost in the passage the passage through empty space , astronomers were actually able to pinpoint the size of different types of these grains , all ranging from less than 1 / 100th of a micron to 10 microns in size , with each micron representing one millionth of a meter 通過(guò)對(duì)穿越真空途中丟失了的光的精細(xì)頻率的密切監(jiān)視,天文學(xué)家已經(jīng)基本上可以查明這些不同微粒的大小,大小從小于百分之一微米到十微米之間,一微米表示一米的百萬(wàn)分之一。
