Discovery ntawm thawj cov ntsiab lus transuranium Tsis yog txog 1940 yog lub ntsiab lus transuranium thawj zaug ua tau zoo thiab txheeb xyuas, thaum ob tus kws kho mob Asmeskas, Edwin Mattison McMillan thiab Philip Hauge Abelson, ua haujlwm ntawm University of California ntawm Berkeley, nthuav tawm uranium oxide rau neutrons los ntawm lub hom phiaj cyclotron.
Leej twg pom cov ntsiab lus transuranium?
thawj lub ntsiab lus transuranium, neptunium, tau tshawb pom hauv xyoo 1940 los ntawm E. M. McMillan thiab P. H. Abelson. Lawv muaj peev xwm cais cov tshuaj lom neeg thiab txheeb xyuas lub ntsiab lus 93 tsim nyob rau hauv cov tshuaj tiv thaiv kab mob hauv qab no [Eq.
Qhov twg yog thawj qhov transuranic?
Thawj Transuranic: Element 93
Nrog nws 93 protons, neptunium yog thawj lub ntsiab lus transuranium, nyob rau sab xis ntawm uranium ntawm Lub Sijhawm Sijhawm. Neptunium yog thawj zaug los ntawm Edwin McMillan thiab Philip H.
Cov ntsiab lus transuranic tsim li cas?
Lawv tau tsim dhau ntawm kev foob pob ntawm cov khoom hauv cov khoom siv acceleratorPiv txwv li, cov fusion nuclear ntawm californium-249 thiab carbon-12 tsim rutherfordium-261. Cov ntsiab lus no yog tsim nyob rau hauv kom muaj nuj nqis nyob rau hauv lub atomic scale thiab tsis muaj txoj kev ntawm loj creation twb tsis tau pom.
Puas muaj pes tsawg transuranic ntsiab?
Muaj 26 lub ntsiabuas yog tom qab uranium ntawm lub sijhawm teem sijhawm. Cov ntsiab lus no yog hu ua cov ntsiab lus transuranium thiab lawv cov lej atomic ntawm 93 txog 118.

Puas yog tag nrho cov ntsiab lus transuranic hluavtaws?
Tag nrho cov ntsiab lus hnyav dua plutonium yog cov hluavtaws tag nrho; lawv yog tsim nyob rau hauv nuclear reactors los yog particle accelerators. Ib nrab ntawm lub neej ntawm cov ntsiab lus no qhia tau hais tias muaj feem ntau ntawm kev txo qis raws li cov lej atomic nce.
Yuav ua li cas thiaj nrhiav tau cov ntsiab lus hypothecation ntawm lub tsheb?
Koj tuaj yeem txheeb xyuas cov ntsiab lus ntawm RC ntawm lub tsheb. Nws yuav raug hais kom meej tias lub tsheb yog hypothecated. Koj tuaj yeem mus ntsib Parivahan lub vev xaib los xyuas seb lub tsheb puas raug nyiaj txiag . Kuv tuaj yeem tshawb xyuas kuv li RC hypothecation li cas hauv online?
Leej twg nrhiav tau lub hauv paus ntsiab lus holographic?
Lub hauv paus ntsiab lus holographic yog cov cuab yeej ntawm quantum gravity theories uas daws cov ntsiab lus ntawm lub qhov dub tsis sib xws hauv txoj hlua txoj hlua. Ua ntej tshaj tawm los ntawm Gerard 't Hooft, nws tau muab txoj hlua-txoj kev txhais lus tseeb los ntawm Leonard Susskind .
Lub ntsiab lus twg suav nrog cov ntsiab lus tseem ceeb thiab hauv qab ntawm cov khoom?
Lub ntsiab lus twg suav nrog qhov tseem ceeb thiab hauv qab ntawm cov ntaub ntawv ntxiv rau kev koom nrog cov khoom? kev nyeem ntawv . Koj hu dab tsi txog cov txheej txheem qhia txog cov ntaub ntawv tseem ceeb? Kev xaiv qhov tseem ceeb / nqes hauv qabyog siv los pab cov tub ntxhais kawm npaj qhov lawv tau nyeem los ntawm kev xaiv qhov tseem ceeb.
Cov ntsiab lus ntawm kev tshawb pom cov lus xaus thiab cov lus pom zoo yog dab tsi?
Kev txhais lus los ntawm tus kws tshawb fawb txog qhov tseem ceeb ntawm qhov kev tshawb pom ntawmib txoj haujlwm tshawb fawb rau cov neeg siv khoom lag luam, nrog rau cov lus pom zoo rau kev nqis tes ua . Cov ntsiab lus ntawm kev tshawb pom thiab qhov xaus yog dab tsi?
