SuavthawjAttosecond laser ntaus ntawvyog nyob rau hauv kev tsim kho
Lub attosecond tau dhau los ua cov cuab yeej tshiab rau cov kws tshawb nrhiav kom tshawb txog lub ntiaj teb hluav taws xob. "Rau cov kws tshawb nrhiav, kev tshawb fawb txog kev tshawb fawb yog qhov yuav tsum muaj, cov txheej txheem kev kawm txuj ci hauv cov protein, lub neej zoo nkauj thiab lwm yam kev tshawb fawb muaj tseeb." Yias yiming tau hais.
Wei Zhiyi, tus kws tshawb fawb ntawm lub koom haum ntawm Physics ntawm Kev Kawm Ntawv Suav teb, ntseeg tias kev nce qib ntawm lub sijhawm, tab sis tseem ceeb tshaj, muaj peev xwm ntawm tib neeg kawm tus qauv ntawm teeb meem, los ntawm kev txav ntawm atoms thiab lwg rau sab hauv ntawm atoms, tuaj yeem tshawb pom kev txav ntawm cov hluav taws xob thiab cuam tshuam kev coj ua, uas tau cuam tshuam Kev tawm tsam loj hauv cov kev tshawb fawb dag. Nws yog ib qho ntawm cov hom phiaj tshawb fawb tseem ceeb uas tib neeg paub txog qhov tseeb ntawm cov tshuab hluav taws xob, thiab tom qab ntawd tswj hwm kev coj tus cwj pwm tsis zoo ntawm atoms. Nrog attosecond pulses, peb tuaj yeem ntsuas thiab txawm tsim tau tus kheej tsom kwm thiab kev pom zoo ntawm lub ntiaj teb ntawm lub ntiaj teb me me, lub ntiaj teb sib txawv.
Txawm hais tias cov kev tshawb fawb no tseem nyob deb deb ntawm cov pej xeem tshaj tawm, kev txhim kho ntawm "Npauj npaim Wings" yuav yeej yog kev tshawb fawb txog kev tshawb fawb "cua daj cua dub". Hauv Suav Teb, AttosecondlaserCov kev tshawb fawb ntsig txog tau muaj nyob rau hauv National Tseem Ceeb Kev Tshawb Fawb tau tsim tsa thiab cov cuab yeej tshawb fawb tau npaj tseg, los ntawm kev soj ntsuam ntawm hluav taws xob suab, dhau los ua qhov zoo tshaj plaws "Electron tsom iav" nyob rau yav tom ntej lub sijhawm daws teeb meem.
Raws li cov ntaub ntawv pej xeem, ib qho attosecondLaser NtausYog tau npaj rau ntawm lub pas dej nkauj nkauj Lakesl hauv Suav teb Guangdong-Hong Kong-Macao Ntau dua Bay. Raws li cov lus tshaj tawm, kev tshaj tawm Afosecond laser chaw yog ua ke ua ke ntawm cov kws tshaj lij kev tshawb fawb ntawm Suav kev kawm, thiab cov ntaub ntawv Songhaman cov ntaub ntawv kev koom tes. Los ntawm cov high pib taw tes tsim qauv, kev tsim kho ntawm ntau cov chaw nres tsheb ntau, siab heev pulse thiab tsis tshua muaj neeg muaj hluav taws xob ntau dua 60as thiab lub zog siab tshaj plaws Txhawm rau 500ev, thiab yog nruab nrog cov ntawv thov kev tshawb fawb platform, thiab cov ntawv teev kev kawm kom tiav rau tus thawj coj hauv ntiaj teb tom qab ua tiav.
