Principles for adaptive high speed precise frequency measurement 自适应高速精密测频原理
Optimized to provide fast , precise frequency measurements with 它提供了与agilent 53131a和
A way to realize precise frequency measure by single chip microcomputer 用单片机实现精密测频的方法
The precise frequency will be determined by the hkmas risk assessment of the institution 至于实际的审查次数,金融管理局会视乎其对有关机构的风险评估而决定。
Each satellite contains four " atomic clocks , " which vibrate at a precise frequency , according to the laws of the quantum theory 每颗卫星都装有4个“原子钟” ,它们根据量子理论法则,以精确的频率振动。
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 通过对穿越真空途中丢失了的光的精细频率的密切监视,天文学家已经基本上可以查明这些不同微粒的大小,大小从小于百分之一微米到十微米之间,一微米表示一米的百万分之一。
