Ib atomic moos yog a moos uas siv cov resonance zaus ntawm atoms raws li nws resonator. Yog koj coj ib yam atom ntawm cesium thiab hais kom nws resonate, nws yuav resonate raws nraim tib zaus li lwm yam atom ntawm cesium. Cesium-133 oscillates ntawm 9, 192, 631, 770 cycles ib ob.
Ib yam li ntawd, lub moos atomic yog dab tsi thiab nws ua haujlwm li cas?
Ib atomic moos yog a moos ntaus ntawv uas siv ib tug hyperfine hloov zaus nyob rau hauv lub microwave, los yog electron hloov zaus nyob rau hauv lub optical los yog ultraviolet cheeb tsam ntawm lub electromagnetic spectrum ntawm atoms raws li tus qauv zaus rau nws lub sijhawm ua haujlwm.
Nws siv sijhawm ntev npaum li cas rau lub moos atomic los teeb nws tus kheej? Thaum koj tig lub xov tooj cua tswj moos nyob rau, nws yuav zaum nco thawj zaug code, yog li nws feem ntau yuav siv sij hawm ntau tshaj ib feeb rau teem nws tus kheej (qee zaum 5 feeb lossis ntev dua) nyob ntawm qhov teeb meem zoo thiab tus qauv txais.
Kuj Paub, lub sij hawm atomic txhais li cas?
Ib atomic moos yog qhov tseeb tshaj plaws hom timepiece nyob rau hauv lub ntiaj teb no, tsim los ntsuas sij hawm raws li kev vibrations hauv atoms . NIST-F1, Tebchaws Asmeskas tus qauv atomic moos , yog hais kom raug li ntawd yuav tsis tau nce lossis poob ib thib ob hauv ntau dua 30 lab xyoo.
Puas yog atomic moos tseem ua haujlwm?
Yog tias cov peev nyiaj tau dhau los raws li tau hais tseg, tom qab WWVB raug kaw koj atomic moos synchronized pab kiag li lawm yuav tsis muaj tseeb, los yog lawv yuav cia li hloov lub sij hawm ntawm Standard mus rau nruab hnub txuag sij hawm. Lawv yuav txuas ntxiv mus ua haujlwm, txawm tias tsis muaj kev teeb tsa tus kheej…
