Qalabka laser attosecond ee ugu horreeya ee Shiinaha ayaa dhismaya

Shiineesmarka horeqalabka laysarka attosecondayaa dhisme ku socda

Attosecond-ku wuxuu noqday qalab cusub oo cilmi-baarayaasha si ay u sahamiyaan adduunka elegtarooniga ah. "Cilmi-baarayaasha, cilmi-baarista attosecond waa qasab, marka labaad, tijaabooyin badan oo saynis ah oo ku saabsan habka dhaqdhaqaaqa miisaanka atomikada ayaa noqon doona mid aad u cad, dadka borotiinka noolaha, ifafaalaha nolosha, miisaanka atomiga iyo cilmi-baarista kale ee la xidhiidha si sax ah." Pan Yiming ayaa yidhi.

Wei Zhiyi, oo ah cilmi-baare ka tirsan Machadka Fiisigiska ee Akadeemiyada Sayniska ee Shiinaha, ayaa aaminsan in horumarka garaaca wadnaha isku xiran ee femtoseconds ilaa attoseconds ma aha oo kaliya horumarka fudud ee qiyaasta waqtiga, laakiin waxa ka sii muhiimsan, awoodda dadka si ay u bartaan qaab-dhismeedka maadada, laga bilaabo dhaqdhaqaaqa atamka iyo molecules ilaa gudaha atomamka iyo kicinta dhaqdhaqaaqa, taas oo kicin karta dabeecadaha elektiroonigga ah. ee cilmi baarista fiisigiska aasaasiga ah. Waa mid ka mid ah yoolalka sayniska ee muhiimka ah ee ay dadku si sax ah u cabbiraan dhaqdhaqaaqa elektaroonigga ah, ogaadaan fahamka sifooyinkooda jireed, ka dibna ay xakameeyaan dabeecadda firfircoon ee elektarooniga ah ee atamka. garaaca garaaca attosecond, waxaan ku cabbiri karnaa oo xitaa macaash samayn karnaa qaybo yaryar oo shakhsi ah, oo markaa samayno indho-indheyn aasaasi ah iyo asalka asalka ah iyo sharraxaadaha adduunka microscopic, adduun ay xukumaan makaanikada quantum-ka.

Inkasta oo cilmi-baaristan ay weli wax yar ka fog tahay dadweynaha guud, kicinta "baalasha balanbaalleyda" ayaa hubaal ah inay horseedi doonto imaatinka cilmi-baarista "dabaylaha". Shiinaha, attosecondleysarkacilmi-baadhisyo la xidhiidha ayaa lagu daray jihada horumarinta muhiimka ah ee qaranka, nidaamka tijaabada ah ee khuseeya ayaa la dhisay iyo qalabka sayniska ayaa la qorsheynayaa, ayaa bixin doona hab cusub oo muhiim ah oo loogu talagalay daraasadda dhaqdhaqaaqa attosecond, iyada oo loo marayo kormeerida dhaqdhaqaaqa elektaroonigga ah, waxay noqotaa "mikroskoob elektaroonig ah" ugu wanaagsan ee qaybta xallinta wakhtiga mustaqbalka.

Sida laga soo xigtay xogta dadweynaha, attosecondqalabka leysarkawaxaa lagu qorsheeyay Shaybaadhka Agabka Harada Songshan ee Shiinaha ee Guangdong-Hong Kong-Macao Greater Bay Area. Sida ay wararku sheegayaan, xarunta laser-ka sare ee attosecond waxaa si wada jir ah u dhisay Machadka Fiisigiska ee Akademiyada Sayniska ee Shiinaha iyo Machadka Xiguang ee Akademiyada Sayniska Shiinaha, Shaybaadhka Agabka ee Songshan Lake ayaa ku lug leh dhismaha. Iyada oo loo marayo naqshadaynta barta bilowga sare, dhismaha xarun khad badan oo badan oo leh soo noqnoqoshada sare, tamarta sare ee photon, qulqulka sare iyo ballaca garaaca garaaca aadka u gaaban ayaa bixiya shucaaca ultrafine oo leh ballaca garaaca garaaca ugu gaaban wax ka yar 60as iyo tamarta ugu sareysa ee photon ilaa 500ev, waxaana lagu qalabeeyaa madal cilmi baaris oo u dhiganta, iyo tusmada dhamaystiran ayaa la filayaa in la gaaro hogaamiyaha caalamiga ah.
