X - rays tau tshawb pom xyoo 1895 los ntawm Wilhelm Conrad Roentgen (1845-1923) uas yog tus xibfwb ntawm Wuerzburg University hauv Tebchaws Yelemees. Roentgen tiv thaiv lub raj nrog cov ntawv dub hnyav, thiab pom lub teeb ntsuab xim fluorescent tsim los ntawm cov khoom siv nyob rau ob peb taw deb ntawm lub raj.
Khaws qhov no hauv kev xav, vim li cas X Ray tau tsim?
Ua ntej x ray tshuab tau invented , cov pob txha tawg, qog thiab qhov chaw ntawm cov mos txwv tau kuaj pom los ntawm kev kuaj lub cev thiab tus kws kho mob qhov kev kwv yees zoo tshaj plaws. Cov neeg mob tau them tus nqi ntawm cov txheej txheem no. Tom qab ntawd lub Kaum Ib Hlis 8th ntawm 1895, German physics xibfwb Wilhelm Conrad Roentgen ua ib qho kev tshawb pom zoo kawg.
Tsis tas li ntawd, xrays ua haujlwm li cas? Thaum twg x - rays tuaj rau hauv kev sib cuag nrog peb lub cev nqaij daim tawv, lawv tsim ib tug duab ntawm ib tug hlau zaj duab xis. Cov ntaub mos mos, xws li tawv nqaij thiab lub cev, tsis tuaj yeem nqus tau lub zog siab rays , thiab lub beam hla dhau lawv. Dub thaj chaw ntawm ib x - ray sawv cev rau thaj chaw uas cov x - rays tau dhau los ntawm cov ntaub so ntswg mos.
Ua raws li qhov xav tau, thawj X ray ua haujlwm li cas?
Ua ntej , lub discovery ntawm X - rays Thaum xyoo 1895, ib tug German physicist, W. C. Roentgen yog ua haujlwm nrog cathode ray tube nyob rau hauv nws chav kuaj. Nws yog ua haujlwm nrog cov raj zoo ib yam li peb lub teeb fluorescent. Nws tshem tawm lub raj ntawm tag nrho cov huab cua, ntim nws nrog ib tug tshwj xeeb roj, thiab dhau ib tug high hluav taws xob voltage los ntawm nws.
Vim li cas qhov kev tshawb pom ntawm X rays tseem ceeb heev?
Kev paub txog kev noj qab haus huv ntau dua X - rays Nws kuj kawm tau tias lawv tuaj yeem thaij duab. Cov nrhiav pom tau sau npe ua txuj ci kho mob, thiab X - rays tsis ntev los ua ib tug tseem ceeb diagnostic tool hauv tshuaj. Nws tso cai rau cov kws kho mob pom hauv tib neeg lub cev thawj zaug yam tsis muaj kev phais.

Dab tsi yog qhov cuab yeej tsim nyog ua ntej kev tshawb xav ntawm tes yuav tsim tau?
Lub microscope yog tsim nyog ua ntej qhov kev xav ntawm tes yuav tsim. Peb tus kws tshawb fawb twg tau txais qhab nia rau cov pov thawj ncaj qha ua rau txoj kev xav ntawm tes? Matthias Schleiden, Theodor Schwann, thiab Rudolph Virchow peb yog txhua tus kws tshawb fawb uas tau pab txhawb txoj kev xav ntawm tes
LEEJ TWG ceeb toom FDR cov neeg German tau tsim riam phom atomic thiab US xav tau ua ib yam?
Xya caum tsib xyoos dhau los, Hungarian-American physicist Leo Szilard tau sau ib tsab ntawv mus rau Tebchaws Meskas Thawj Tswj Hwm Franklin Roosevelt qhia kev txhawj xeeb tias cov kws tshawb fawb German yuav sai sai no qhib qhov zais cia los tsim thawj lub foob pob tawg
Lub chaw tsim hluav taws xob nuclear tsim tau li cas?
Nuclear fission tsim cua sov Reactors siv uranium rau nuclear roj. Cov uranium tau ua tiav rau hauv cov me me ceramic pellets thiab muab tso ua ke rau hauv cov raj hlau kaw hu ua roj rods. Lub tshav kub tsim los ntawm fission hloov cov dej mus rau hauv chav, uas tig lub turbine los tsim hluav taws xob tsis muaj carbon
Vim li cas thiaj nres thiab pib codons tsim nyog rau kev tsim cov protein?
Pib thiab nres codons yog ib qho tseem ceeb vim hais tias lawv qhia lub xov tooj ntawm tes machinery qhov twg yuav pib thiab xaus kev txhais lus, txheej txheem ntawm kev ua cov protein. Qhov pib codon cim qhov chaw ntawm qhov kev txhais lus rau hauv protein ntau pib. Qhov nres codon (los yog termination codon) cim lub vev xaib uas txhais lus xaus
Henri Becquerel nrhiav tau dab tsi uas ua rau nws tau txais 1903 Nobel nqi zog Nws nrhiav tau dab tsi txog lub caij uranium?
Teb: Henri Becquerel tau txais ib nrab ntawm qhov khoom plig rau nws qhov kev tshawb pom ntawm cov hluav taws xob tsis zoo. Teb: Marie Curie tau kawm txog cov hluav taws xob ntawm tag nrho cov tebchaw uas muaj cov xov tooj cua paub, suav nrog uranium thiab thorium, uas nws tom qab pom kuj tseem muaj xov tooj cua
