Hauv kev tsim khoom lag luam, hniav puas tag ib txwm muaj qhov tseem ceeb cuam tshuam cuam tshuam rau kev tsim khoom thiab cov khoom lag luam zoo. Nrog kev nce qib ntawm science thiab thev naus laus zis thiab kev ua kom zoo dua ntawm cov txheej txheem, kev tshawb fawb ntawmMuaj HniavKev puas mechanism yog ua ntau dua thiab ntau dua qhov tob, tsom mus nrhiav cov ntsiab lus tseem ceeb kom ncua lub neej ntawm cov hniav.
Muaj ntau qhov laj thawj rau cov hniav puas tsuaj, feem ntau yog suav nrog kev hnav tshuab, thermal hnav, tshuaj hnav thiab diffusion hnav. Cov khoom siv tshuab puas yog tshwm sim los ntawm cov khoom siv nyuaj hauv cov khoom ua haujlwm kom ua kom muaj kev sib tsoo ntawm cov hniav sib txawv yog qhov tshwj xeeb tshaj yog pom thaum txiav ceev. Kev puas tsuaj ua hluav taws kub yog vim muaj ntau tus nqi tsim hluav taws xob ntau thaum lub sijhawm ua haujlwm txiav, ua rau cov hniav sib cais los ntawm cov hniav tawg. Tshuaj lom zem yog cov oxygen nyob rau saum huab cua ntawm cov khoom siv hniav ntau, kev tsim cov khoom sib xyaw ntawm cov khoom tawg, lub nti tawm, ua rau cov hniav puas. Kev ua txhaum kev sib cais, ntawm qhov tod tes, yog tias thaum lub sijhawm txiav tawm ntawm cov hniav thiab ua rau nws cov txheej sab thiab ua nws cov txheej sab npoo.
Rau cov kev hnav no, cov kws tshawb nrhiav tau npaj siab rau ntau txoj hauv kev los txuas lub neej pabcuam. Ua ntej tshaj plaws, kev xaiv tsim nyog ntawm cov ntaub ntawv hniav hniav yog tus yuam sij. Raws li cov yam ntxwv ntawm cov txheej txheem txheej txheem thiab kev siv cov khoom siv, xaiv cov hniav hniav uas muaj hardness txaus, hnav tsis taus thiab txoj kev nruj yuav ua rau txo kev puas tsuaj. Piv txwv li, thaum kev siv cov khoom nyuaj-rau-txiav nrog cov khoom tawv loj rau cov vuam zoo thiab muaj zog rau kev sib txawv yuav tsum tau xaiv.
Qhov thib ob, tsim kom zoo hniav geometry cov lus tseem ceeb kuj yog ib qho tseem ceeb ntawm kev ua haujlwm ntawm lub neej. Tsim nyog cov hniav sib txuas thiab cov hniav hniav yuav tsim nyog cov duab tuaj yeem txo cov quab yuam thiab txiav cua sov, thiab txo cov hniav puas. Piv txwv li, txo qis ntawm cov ces kaum sab hauv ntej thiab sab nraub qaum thiab kev siv ntawm qhov tsis zoo ntawm ntug kev puas tuaj yeem txo tau cov hnav ntawm ntug kev txiav. Nyob rau tib lub sijhawm, kev sib tsoo ib qho kev sib tsoo tsis zoo lossis ntug arc tseem tuaj yeem txhim kho lub zog ntawm cov hniav thiab tiv thaiv chipping.
Ib qho ntxiv, xaiv tsim nyog ntawm kev txiav kev txiav tawm thiab siv cov roj txias txias kuj yog ib txoj hauv kev zoo los txuas ntxiv hniav lub neej. Qhov tob ntawm kev txiav thiab pub yog loj heev, lub zog yuam kom nce, thiab cov hniav muaj kev puas tsuaj yog nrawm. Yog li ntawd, nyob rau hauv lub premise ntawm ensuring ua kev ua tau zoo, tus nqi txiav yuav tsum muaj tsawg. Nyob rau tib lub sijhawm, kev siv cov roj nplua nyeem txias tuaj yeem nqus thiab tshem tawm feem ntau ntawm cov hniav thiab ua haujlwm kom sov, yog li txo cov hniav puas.
Thaum kawg, txoj kev ua haujlwm kom raug thiab cov txheej txheem kev nruj yog cov tseem ceeb uas tsis tuaj yeem tsis quav ntsej. Hauv kev txiav cov txheej txheem, cov hniav yuav tsum sim ua kom cov hniav tsis dais lossis tsis muaj qhov hloov pauv ntawm lub nra, kom zam dhau cov hniav vim tsis sib luag thiab tawg. Nyob rau tib lub sijhawm, kom ntseeg tau tias cov txheej txheem txheej txheem muaj qhov ua kom nruj, txo cov kev co, tuaj yeem ua tau zoo txuas ntxiv lub neej ntawm cov hniav.
Hauv cov ntsiab lus, cov ntsiab lus tseem ceeb kom txuas cov kev pabcuam lub neej ntawm kev xaiv cov khoom sib xyaw, kev xaiv cov roj ntsha uas tsim nyog thiab cov txheej txheem kev ua haujlwm kom raug thiab cov txheej txheem kev ua haujlwm kom raug. Nrog kev txuas ntxiv mus ntxiv ntawm cov kev tshawb fawb ntawm cov txheej txheem ntawm cov hniav sib cais, nws ntseeg tau tias muaj kev loj hlob tshiab rau hauv kev txhim kho cov teb lag luam.
Tom qab ntawd, peb yuav txuas ntxiv hloov cov ntaub ntawv ntxiv, thiab koj tuaj yeem nrhiav cov ntaub ntawv ntau ntxiv ntawm peb lub vev xaib (mob siab rau ntawm peb lub vev xaib (mob siab rau ntawm peb lub vev xaib (mob siab rau. Blog.
Yog lawm, koj kuj tseem tuaj yeem them sai sai rau peb cov ntaub ntawv social counter:
