atomic standard造句

• "It's a good clock, but atomic standards are much better ."
• In this manner, locking of the frequency comb output to an atomic standard can be performed in a single step.
• All non-atomic standard probability spaces are mutually isomorphic \ mod 0; one of them is the interval ( 0, 1 ) with Lebesgue measure.
• In 1955, he developed, in collaboration with Jack Parry, the first practical atomic clock by integrating the caesium atomic standard with conventional quartz crystal oscillators to allow calibration of existing time-keeping.
• QZSS will also be able to use a Two-Way Satellite Time and Frequency Transfer ( TWSTFT ) scheme, which will be employed to gain some fundamental knowledge of satellite atomic standard behavior in space as well as for other research purposes.
• "You see, our task is to create the most accurate and reproducible fundamental standards we can, " said Thomas Parker, chief of the Atomic Standards Group at the Boulder laboratory of the National Institute of Standards and Technology, or NIST . " Users catch up later by adapting our research to specific applications ."
