J. J. Thomson nrhiav tau lub electron nyob rau hauv 1897 thaum nws ntsuas tus nqi-rau-mass piv rau electrons nyob rau hauv ib tug beam. Tab sis tus nqi ntawm tus nqi thiab seb nws puas yog qhov tseem ceeb tseem qhib cov lus nug. Thomson thiab lwm tus tau sim ntsuas tus nqi hluav taws xob tsis tuaj yeem los ntawm kev saib cov huab ntawm cov tee dej.
Leej twg thawj zaug xam qhov loj ntawm ib tug electron?
Qhov loj-rau-them tus nqi ntawm cov hluav taws xob yog thawj zaug kwv yees los ntawm Arthur Schuster hauv xyoo 1890 los ntawm kev ntsuas qhov deflection ntawm "cathode rays" vim muaj qhov paub sib nqus hauv qhov chaw. cathode ray tube. Nws yog xya xyoo tom qab ntawd J. J.
Millikan xam qhov loj ntawm ib qho hluav taws xob li cas?
Hauv xyoo 1909, Robert Millikan thiab Harvey Fletcher tau ua qhov kev sim roj pooblos txiav txim siab tus nqi hluav taws xob. … Qhov ceev ntawm cov roj tau paub, yog li Millikan thiab Fletcher tuaj yeem txiav txim siab cov tee dej ntawm lawv cov radii pom (txij li ntawm lub radii lawv tuaj yeem xam qhov ntim thiab yog li, qhov loj).
Vim li cas ib qho hluav taws xob muaj huab cua?
tl;dr Electrons yog qhov tseem ceeb thiab yog li tsis muaj ntim. Kev sib cuam tshuam nrog Higgs teb (Higgs boson) muab cov khoom siv hluav taws xob zoo ib yam rau pawg(hais lwm txoj hauv kev, Higgs teb muab cov hluav taws xob nws qhov loj). Peb txoj kev xav yog ib yam dab tsi muaj huab hwm coj vim nws yog ua los ntawm cov khoom.
Leej twg nrhiav tau lub electron?
Txawm tias J. J. Thomsontau lees paub nrog qhov kev tshawb pom ntawm cov hluav taws xob raws li nws qhov kev sim nrog cathode rays hauv xyoo 1897, ntau tus kws kho mob, suav nrog William Crookes, Arthur Schuster, Philipp Lenard, thiab lwm tus, uas tau ua kev sim cathode rays thov. tias lawv deserved qhov credit.
