J. J. Thomson coj kev tshawb fawb mus rau qhov siab tshiab nrog nws xyoo 1897 nrhiav pom ntawm electron - thawj subatomic particle. Nws kuj pom thawj cov pov thawj tias cov khoom ruaj khov tuaj yeem muaj nyob hauv isotopes thiab tau tsim ib qho ntawm cov cuab yeej muaj zog tshaj plaws hauv kev tshuaj ntsuam chemistry - qhov loj spectrometer.
Ib yam li ib tug yuav nug, vim li cas JJ Thomson qhov kev tshawb pom tseem ceeb?
Qhov tseem ceeb ntawm Discovery . J. J. Thomson txoj kev nrhiav pom yog tseem ceeb vim nws tau pom tias cov atom particle tuaj yeem raug faib ua cov khoom me me. Nws nrhiav pom coj mus rau cov qauv ntxaws ntxiv ntawm lub atom, suav nrog ib qho uas peb siv niaj hnub no.
Ib sab saum toj no, JJ Thomson nrhiav tau dab tsi? Electron Isotope Subatomic particle
Ib yam li ntawd, koj tuaj yeem nug, JJ Thomson nto moo rau dab tsi?
J. J. Thomson , nyob rau hauv tag nrho Sir Joseph John Thomson , (yug Lub Kaum Ob Hlis 18, 1856, Cheetham Hill, ze Manchester, England-tuag Lub Yim Hli 30, 1940, Cambridge, Cambridgeshire), Askiv tus kws kho mob uas tau pab hloov pauv kev paub txog atomic qauv los ntawm nws qhov kev tshawb pom ntawm electron (1897).
JJ Thomson nrhiav tau dab tsi thiab thaum twg?
Xyoo 1897, J. J. Thomson nrhiav pom cov hluav taws xob los ntawm kev sim nrog Crookes, lossis cathode ray, raj. Nws pom tias cathode rays tau raug nqi. Thomson pom tau hais tias tus qauv lees txais ntawm ib qho atom ua tsis suav rau qhov tsis zoo lossis qhov txiaj ntsig zoo.

Vim li cas qhov piv txwv tseem ceeb hauv kev lag luam zaub mov?
Kev kuaj cov zaub mov yog txheej txheem siv los xyuas tias cov khoom noj muaj kev nyab xeeb thiab tsis muaj cov kab mob phem, lossis nws tsuas muaj cov tshuaj ntxiv uas tau tso cai ntawm qib uas tau txais, lossis tias nws muaj cov qib zoo ntawm cov khoom xyaw tseem ceeb thiab nws cov ntawv tshaj tawm yog raug, los yog kom paub cov qib ntawm cov as-ham tam sim no
Vim li cas nws tseem ceeb kom paub tias koj txhais li cas ntxiv?
Txhais qhov seem. Kev txhais cov lus tseem ceeb yog qhov tseem ceeb thaum koj faib ua lej vim tias koj tuaj yeem tau txais qhov teeb meem tsis raug yog tias koj tsis txhais cov seem kom raug. Piv txwv li, nyob rau hauv ib lo lus teeb meem koj yuav tsum tau faib thiab faib tawm rau koj nrog ib tug seem thiab koj yuav tsum tau muab sau tseg
Vim li cas qhov tseem ceeb ntawm qhov tseem ceeb?
Thaum koj pom tus nqi kiag li hauv qhov teeb meem lossis qhov sib npaug, nws txhais tau hais tias txhua yam nyob hauv tus nqi tiag tiag yog qhov zoo. Cov txiaj ntsig tsis zoo feem ntau siv rau hauv cov teeb meem cuam tshuam nrog kev nyob deb thiab qee zaum siv nrog qhov tsis sib xws. Qhov ntawd yog qhov tseem ceeb uas yuav tsum nco ntsoov nws zoo li qhov deb ntawm xoom
Vim li cas cov nuj nqis tseem ceeb tseem ceeb thaum qhia txog kev ntsuas?
Cov duab tseem ceeb yog qhov tseem ceeb los qhia qhov tseeb ntawm koj cov lus teb. Qhov no yog qhov tseem ceeb hauv kev tshawb fawb thiab engineering vim tias tsis muaj cov cuab yeej ntsuas tuaj yeem ua qhov ntsuas nrog 100% precision. Siv cov nuj nqis tseem ceeb tso cai rau tus kws tshawb fawb paub tias cov lus teb meej npaum li cas, lossis qhov tsis paub meej npaum li cas
Yuav ua li cas yog vim li cas tus qauv ntawm ib qho enzyme tseem ceeb heev rau nws txoj haujlwm hauv cov khoom muaj sia?
Enzymes ua kom cov tshuaj tiv thaiv uas tshwm sim hauv cov hlwb. Qhov kev ua haujlwm no cuam tshuam ncaj qha rau lawv cov qauv, nrog rau txhua qhov enzyme tau tshwj xeeb zoo li tus ua kom muaj zog rau ib qho tshuaj tiv thaiv. Kev poob ntawm cov qauv ua rau poob haujlwm. - Kub, pH, thiab kev tswj cov molecules tuaj yeem cuam tshuam rau kev ua haujlwm ntawm cov enzymes
