Lub cryotron yog tus hloov uas ua haujlwm siv superconductivityLub cryotron ua haujlwm ntawm lub hauv paus ntsiab lus uas cov hlau nplaum ua kom puas superconductivity. Cov cuab yeej yooj yim no muaj ob txoj kab hluav taws xob superconducting (xws li tantalum thiab niobium) nrog qhov kub thiab txias sib txawv (Tc).
Thaum cryotron tau tsim?
Lub cryotron yog ib qho khoom siv hluav taws xob superconductive, magnetic-controlled gating device invented by MIT's Dudley Buck, who nted out the idea in his notebook in December 1953. Qhov kev tivthaiv tau pom tias yog ib qho kev hloov pauv hloov mus rau qhov me me ntawm cov khoos phis tawj loj ntawm xyoo 1950s.
txhais li cas los ntawm qhov tseem ceeb magnetic teb?
['krid·ə·kəl mag′ned·ik 'fēld] (krid-state physics) Cov teb hauv qab no uas cov khoom siv hluav taws xob superconductive yog superconducting thiab saum toj no uas cov khoom yog ib txwm, ntawm ib qhov ntsuas kub thiab qhov tsis muaj tam sim no.
Lub teb chaws cuam tshuam dab tsi?
Meissner effect, tshem tawm ntawm lub tshav pob hlau nplaumlos ntawm cov khoom siv sab hauv uas yog nyob rau hauv tus txheej txheem ntawm los ua ib tug superconductor, uas yog, poob nws tsis kam mus rau qhov ntws. Cov hluav taws xob tam sim no thaum txias qis dua qhov ntsuas kub, hu ua qhov hloov pauv kub, feem ntau yog ze rau xoom xoom.
Lub ntsiab lus rau National Science Day 2020 yog dab tsi?
Lub ntsiab lus rau National Science Day 2020 yog " Women in Science". Xyoo no, National Science Day yuav ua kev zoo siab ntawm Vigyan Bhawan Lub Ob Hlis 28 nrog cov poj niam hauv kev tshawb fawb raws li lub ntsiab lus tseem ceeb ntawm txoj haujlwm.
Pom zoo:
Txhais li cas los txhais ib yam dab tsi?
Lub ntsiab lus ntawm cov ntsiab lus yog ua tiav nyob rau hauv ib txoj kev uas yog raws li qhov chaw los yog lub ntsiab lus. Ib qho piv txwv ntawm cov ntsiab lus yog ib chav ua vaj qhia thaum ua haujlwm hauv vaj . Ib qho piv txwv ntawm lub ntsiab lus txhais li cas?
Puas qhov loj ntawm tus txiv neej txhais tes txhais li cas?
Ib tug txiv neej tes Size Hints at His Athletic Ability Cov txiv neej nrog ntiv nplhaib ntev dua txhais tes muaj zog dua, tsis hais lawv lub hnub nyoog thiab lub cev loj npaum li cas, ib pab pawg ntawm leej txiv-tus kws tshawb fawb pom. Ntau qhov kev tshawb fawb qhia txog qhov kev xav uas ntev ntiv tes txuas nrog kev ua kis las zoo tshaj thiab tag nrho lub zog .
Benumbed txhais li cas phau ntawv txhais lus?
xub. / (bɪˈnʌm) / verb (tr) ua kom loog lossis tsis muaj zog; deaden lub cev xav nyob rau hauv, raws li los ntawm txias. (feem ntau passive) ua kom tsis muaj zog; stupefy (lub siab, senses, yuav, thiab lwm yam) Lub ntsiab lus ntawm benumbed yog dab tsi?
Txhais tau tias dav dav txhais li cas?
adj. 1 muaj zoo heev los ntawm sab rau ib sab. 2 ntawm loj loj los yog scope; dav lossis dav. ib qho postpositive uas muaj qhov tshwj xeeb, esp. ntawm ib sab mus rau sab . txhais li cas? "Rau qhov" txhais tau tias tus neeg twg yog:
Cryotron ua haujlwm li cas?
Lub cryotron yog qhov hloov pauv uas ua haujlwm siv superconductivity. Lub cryotron ua haujlwm ntawm lub hauv paus ntsiab lus uas cov hlau nplaum ua kom puas tsuaj superconductivity… Thaum cov cuab yeej no tso rau hauv cov kua dej helium da dej ob lub xov hlau ua superconducting thiab yog li tsis muaj kev tawm tsam ntawm cov hluav taws xob tam sim no .
