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.
