Albert Einstein txoj kev xav ntawm kev sib txheeb li cas hloov txoj cai ntawm kev txuag hluav taws xob ? Thaum ib yam khoom lossis lub cev ua haujlwm ntawm lwm yam khoom, qee qhov ntawm nws zog pauv mus rau qhov khoom ntawd.
Ua li no, txoj cai lij choj ntawm kev txuag hluav taws xob nrhiav tau li cas?
Xyoo 1842, Julius Robert Mayer nrhiav pom tus Txoj Cai Kev txuag hluav taws xob . Hauv nws daim ntawv compact tshaj plaws, nws tam sim no hu ua Thawj Txoj cai Thermodynamics: zog tsis yog tsim los sis puas tsuaj. Qhov no tau xav, tab sis dab tsi tsis yog qhov ntawd zog cov nyiaj tso tawm sib txawv dav rau tib txoj kev lwj.
Qhov thib ob, koj ua li cas hloov cov teeb meem rau hauv lub zog? Nyob rau hauv ib qho kev tawm tsam nuclear fission, teeb meem hloov pauv rau hauv lub zog . Nws tau pom tias thaum twg U-236 dhau los ua cov tshuaj tiv thaiv fission, Kr-92, 141-Ba thiab peb neutrons raug tso tawm. Tab sis lawv cov huab hwm coj tsis ntxiv mus rau tag nrho cov huab hwm coj ntawm U-236 atom. Yog li qee qhov loj yog ua hloov dua siab tshiab rau zog.
Ua raws li qhov xav tau, txoj cai ntawm kev txuag hluav taws xob yog dab tsi?
Cov txoj cai ntawm kev txuag hluav taws xob yog a txoj cai ntawm science uas hais tias zog tsis tuaj yeem tsim lossis rhuav tshem, tab sis tsuas yog hloov ntawm ib daim ntawv mus rau lwm qhov lossis hloov ntawm ib qho khoom mus rau lwm qhov.
Txoj cai ntawm kev txuag hluav taws xob puas tuaj yeem tawg?
Cov txoj cai ntawm kev txuag hluav taws xob yog empirical txoj cai ntawm physics. Nws hais tias tag nrho tus nqi ntawm zog nyob rau hauv ib qho kev sib cais system tseem nyob tas li lub sij hawm. Thiab nws tsis yooj yim sua kom tawg.

Txoj cai lij choj ntawm kev txuag hluav taws xob siv li cas rau kev hloov hluav taws xob?
Txoj cai lij choj ntawm kev txuag hluav taws xob hais tias lub zog tsis tuaj yeem tsim lossis rhuav tshem - tsuas yog hloov los ntawm ib hom ntawm lub zog mus rau lwm qhov. Qhov no txhais tau hais tias ib qho system ib txwm muaj tib lub zog, tshwj tsis yog nws ntxiv los ntawm sab nraud. Tib txoj kev siv lub zog yog hloov lub zog ntawm ib daim ntawv mus rau lwm qhov
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
Kev sib raug zoo ntawm hluav taws xob thiab hluav taws xob teb yog dab tsi?
Electric teb yog txhais raws li lub zog hluav taws xob ib chav tsev nqi. Cov kev taw qhia ntawm lub teb yog coj mus rau qhov kev taw qhia ntawm lub zog nws yuav ua rau ib tug zoo kuaj nqi. Cov hluav taws xob hluav taws xob yog radially sab nraud los ntawm tus nqi zoo thiab radially mus rau qhov tsis zoo ntawm tus nqi
