WebbThe thermal beam primary clocks CS1 and CS2 continue to be operated as backup frequency references for the realization of the time scales UTC(PTB) and TA(PTB). Both continue to contribute to the determination of the TAI scale unit with maximum weight. Substantial progress has been made in the development of optical frequency standards … WebbBased on its research and development work, PTB provides a wide range of metrological services. The central task in this context – laid down by law – is to realize and to disseminate the units as accurately as possible. In this way, PTB ensures that uniform measures are used, not only in Germany, but throughout the world. how to say pad thaihttp://time.kinali.ch/ptti/1996papers/Vol%2028_20.pdf how to say pads in spanish
