Xav kom muab koj lub moos rau lub sijhawm kom yog? Tom qab ntawd koj yuav xav muab nws tso rau ib qho chaw cim atomic . Atomic ntoos yog txhais, qhov tseeb tshaj plaws hauv lub ntiaj teb thiab yog cov txheej txheem uas tag nrho lwm lub sijhawm timepieces. Txawm hais tias muaj ntau lub cim atomic clocks thoob ntiaj teb, ib qho siv los ntawm tsev automation cov cuab yeej nyob sab nrauv Boulder, Colorado.
Dab Tsi Yog Lub Tsev Atomic Moos?
Thaum koj yuav ib lub moos uas sau qhia nws tus kheej tias "atomic clock," koj yeej tseem yuav ib qho khoom siv uas yog lub sijhawm ua haujlwm rau Teb Chaws Asmeskas tsoom fwv Atomic Clock nyob sab nrauv Boulder, Colorado. Hauv tsev atomic clocks yog tsim los kom tau txais lub xov tooj cua teeb liab tshaj tawm hauv National Institute of Standards thiab Technology (NIST) nyob rau hauv Colorado thiab synchronize rau cov teeb liab ntawd.
Cov kev txwv ntawm Atomic Clocks
Feem ntau ntawm tsev atomic clocks tsuas yog ua hauj lwm (synchronize mus rau lub sij hawm Atomic) hauv teb chaws Mes Kas. Qhov no txhais tau hais tias koj lub tsev atomic yuav tsis ua kom zoo dua nyob rau hauv Hawaii, Alaska, lossis lwm lub tebchaws uas tsis yog North America. Lub tsev atomic clocks tsuas ua haujlwm hauv qee thaj chaw ntawm Canada thiab Mexico.
Lwm txoj kev txwv ntawm lub tsev atomic ntoos yog tias lawv yuav tsis tau txais cov teeb liab NIST hauv cov vaj tse loj uas muaj hlau siv. Tsav ntav los ze rau qhov rais hauv cov tsev no feem ntau yuav daws qhov teeb meem ntawm qhov teeb meem.
Synchronising Computers
Feem ntau ntawm cov tshuab computer khiav lag luam yuav ua kom lub computer lub moos nrog NIST lub sijhawm cov kev pabcuam, uas koj muaj Internet kev txuas. Yog tias koj lub kaspivtaw tsis tuaj yeem kho cov sijhawm, nws muaj sijhawm ntau cov sijhawm sib txuas los pab koj lub computer ua qhov no.
Yog tias koj xav kuaj koj lub computer (lossis tsev), koj tuaj yeem nkag mus tau lub sijhawm NIST ntawm www.time.gov.
Synchronizing Tsev Automation Devices
Thaum siv lub tshuab computer los tswj koj cov cuab yeej siv hauv tsev, koj cov cuab yeej siv yuav tau synchronize lawv tus kheej mus rau tus maub los. Siv lub tsev automation lub qhov rooj thiab lub computer lub sij hawm hauv Internet sync xyuas kom txhua lub tsev automation cov cuab yeej ua haujlwm nrog NIST lub sijhawm.
