Hluav taws xob yog ib daim ntawv ntawm lub zog, tsim nyog hu ua hluav taws xob zog. Qhov no hluav taws xob lub zog yog thauj los ntawm ib tug neeg xyuas pib (piv txwv li hlau hlau) los ntawm electrons, uas yog hais. Hauv qhov kev xav no, hluav taws xob tsis yog feem ntau , tab sis tsuas yog ib daim ntawv ntawm lub zog nqa los ntawm hais.
Ib yam li ntawd, qhov xwm ntawm hluav taws xob yog dab tsi?
Qhov yooj yim xwm ntawm hluav taws xob yog, thaum twg lub cev tsis zoo them nyiaj txuas nrog lub cev muaj txiaj ntsig zoo los ntawm tus neeg xyuas pib, cov khoom siv hluav taws xob ntau dhau ntawm lub cev tsis zoo pib ntws mus rau lub cev zoo los them nyiaj rau qhov tsis muaj electrons hauv lub cev zoo.
Qhov thib ob, tus qauv particle ntawm hluav taws xob yog dab tsi? Cov tub ntxhais kawm xaus qhov particle qauv ntawm hluav taws xob raws li hauv qab no: • Ob hom kev them nqi cov khoom , zoo (protons) thiab tsis zoo (electrons), muaj nyob. Kev them nqi tsis tuaj yeem tsim lossis rhuav tshem - tus nqi raug khaws cia. Cov nqi them zoo raug kho thiab cov nqi tsis zoo tuaj yeem txav mus los. Zoo li cov nqi them rov qab; tsis zoo li tus nqi nyiam.
Tsis tas li ntawd, lub ntsiab lus ntawm particulate xwm ntawm cov teeb meem yog dab tsi?
Cov khoom. Tag nrho teeb meem yog feem ntau hauv xwm . Qhov no yeej txhais tau tias uas nruab nrab ntawm cov khoom sib cais ntawm teeb meem muaj qhov chaw uas tsis muaj teeb meem.
Dab tsi yog qhov xwm txheej yog nws txuas ntxiv lossis ntu?
Teeb meem tsis yog tsis tu ncua thiab yog feem ntau hauv xwm , i.e. yog ua los ntawm cov khoom.

Lub ntsiab txhais ntawm lo lus hluav taws xob hluav taws xob yog dab tsi?
Npe. Cov hluav taws xob hluav taws xob txhais tau tias yog hluav taws xob hluav taws xob uas tso cai rau kev ua haujlwm kom tiav. Ib qho piv txwv ntawm lub zog hluav taws xob yog lub zog los ntawm lub qhov hluav taws xob ntsaws. YourDictionary txhais thiab siv piv txwv
Dab tsi yog qhov txawv ntawm kev txuag hluav taws xob thiab lub hauv paus ntsiab lus ntawm kev txuag hluav taws xob?
Lub caloric txoj kev xav tau khaws cia tias cov cua sov tsis tuaj yeem tsim los yog rhuav tshem, qhov kev txuag ntawm lub zog ua rau lub hauv paus ntsiab lus tsis sib xws uas cov cua sov thiab cov tshuab ua haujlwm sib hloov tau
Dab tsi yog cov yam ntxwv ua siab hloov hluav taws xob hloov hluav taws xob LET muaj thaum piv nrog LET hluav taws xob tsawg?
Dab tsi yog cov yam ntxwv ua kom muaj hluav taws xob hloov hluav taws xob siab (LET) hluav taws xob muaj thaum piv nrog cov hluav taws xob qis-LET? Cov huab hwm coj ntau ntxiv, txo qhov nkag mus. (Vim lawv cov nqi hluav taws xob thiab cov khoom loj heev, lawv ua rau ntau ionizations hauv cov ntaub so ntswg, sai sai poob lub zog
Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms?
Tus nqi zoo attracts tus nqi tsis zoo thiab ua rau lwm tus nqi zoo. Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms? Cov nqi hluav taws xob yog cov cuab yeej ntawm tag nrho cov atoms
Dab tsi yog qhov zoo ntawm kev siv lub tshuab hluav taws xob hloov hluav taws xob hauv atomic absorption?
Qhia qhov zoo thiab qhov tsis zoo ntawm lub cub tawg piv nrog kev siv cov nplaim taws hauv atomic absorption spectroscopy. Cov txiaj ntsig tseem ceeb yog ntau dua rhiab heev (concentration thiab tshwj xeeb tshaj yog loj). Lub ntsiab tsis zoo yog cov cuab yeej cuab tam ntau dua thiab cov nqi ntsuas
