Kev txuag vs Kev khaws cia
Kev txuag thiab khaws cia yog ob qho tib si uas tsim nyog los tiv thaiv yav tom ntej ntawm qee yam tseem ceeb hauv ntiaj teb xws li ib puag ncig, lub zog ntuj thiab lwm yam. Txawm li cas los xij, qee zaum ob lo lus no tau pom tias siv sib hloov uas yuav tsum tsis txhob muaj vim qhov sib txawv ntawm kev txuag thiab khaws cia.
Kev txuag yog dab tsi?
Kev txuag yog lo lus siv los khaws cia tshwj xeeb tshaj yog ib puag ncig ntuj, cov peev txheej, thiab cov tsiaj qus. Ib cheeb tsam kev txuag yuav txhais tau tias thaj chaw uas muaj ib puag ncig uas tsim nyog tau txais kev tiv thaiv tshwj xeeb los ntawm txoj cai tiv thaiv kev hloov pauv uas yuav ua rau ib puag ncig zoo.
Cov ntsiab lus xws li kev txuag hluav taws xob, kev txuag hluav taws xob lossis kev txuag lub zog kuj tseem siv dav niaj hnub no. Ib lub hauv paus ntsiab lus tseem ceeb tshaj plaws uas siv hauv Physics hais txog kev txuag hluav taws xob yog tias tag nrho lub zog ntawm txhua lub cev tsis raug rau kev ua haujlwm sab nraud tseem nyob tas li, txawm tias muaj kev hloov pauv sab hauv (xws li tshuaj tiv thaiv lossis hloov lub cev).
Tus neeg txhawb lossis tus neeg tawm tswv yim txog kev txuag ib puag ncig yog hu ua tus kws saib xyuas kev noj qab haus huv thaum lo lus environmentalist kuj siv rau lub hom phiaj. Kev txuag yog lo lus siv nyob rau hauv kev nkag siab ntawm kev khaws cia rau yav tom ntej. Xav txog kev siv lub sij hawm txuag dej. Nws tsuas yog txhais tau hais tias cov dej tau khaws cia rau yav tom ntej. Kev txuag dej yog lub luag haujlwm tseem ceeb ntawm tsoomfwv hauv xeev Arizona hauv Tebchaws Meskas vim nws yog thaj chaw suab puam.
Kev khaws cia yog dab tsi?
Kev khaws cia, ntawm qhov tod tes, yog kev ua kom muaj kev nyab xeeb thiab tsis muaj kev puas tsuaj lossis lwj. Ib qho piv txwv zoo ntawm qhov no yog kev ua ntawm kev khaws cov ntawv sau ntawm xibtes nyob rau hauv qhov zoo hauv lub tsev qiv ntawv. Kev khaws cia ntawm ib qho khoom hu rau kev sim tswj qhov zoo lossis qhov xwm txheej ntawm cov khoom. Kev khaws cia ntawm artefacts thiab archives feem ntau pom nyob rau hauv tsev cia puav pheej.
Muaj ntau hom kev khaws cia xws li keeb kwm khaws cia, khaws cia textile, tshawb xyuas khaws cia thiab lwm yam. Kev txuag keeb kwm yog ib txoj hauv kev tshaj lij los khaws thiab tiv thaiv cov tsev, khoom siv, toj roob hauv pes lossis lwm yam khoom ntawm qhov tseem ceeb ntawm keeb kwm.
Textile preservation yog hais txog cov txheej txheem uas textiles tau tu thiab khaws cia kom tsis txhob muaj kev puas tsuaj yav tom ntej. Tseem muaj lwm yam kev khaws cia xws li kev khaws cia hauv tsev qiv ntawv thiab kev khaws duab kos duab ib yam nkaus. Cov ntawv tshawb fawb khaws cia yog cov kev tshawb fawb uas suav nrog kev sau thiab tshuaj xyuas cov ntaub ntawv hais txog lub cev ntawm cov ntaub ntawv muaj nyob hauv cov tsev qiv ntawv.
Kev txuag thiab khaws cia yog dab tsi?
• Kev txuag yog kev tiv thaiv, khaws cia lossis ua tib zoo tswj hwm ib puag ncig thiab cov peev txheej ntuj xws li hav zoov, tsiaj qus, av, thiab dej.
Example:
Kev khaws cia tej yam ntuj tso rau yav tom ntej
Kev txuag av - tiv thaiv av tiv thaiv kev yaig lossis kev puas tsuaj
Kev txuag dej - kev txuag dej
Nyob hauv Physics
Kev txuag ntawm lub zog - lub hauv paus ntsiab lus yog tias tag nrho cov kab hluav taws xob hauv lub kaw lus kaw tsis tu ncua thiab tsis cuam tshuam los ntawm cov txheej txheem tshwm sim hauv qhov system.
• Kev khaws cia yog ua kom muaj kev nyab xeeb lossis tsis muaj kev puas tsuaj lossis lwj: tiv thaiv lossis tiv thaiv.
Example
Kev khaws zaub mov - tiv thaiv zaub mov kom tsis txhob lwj lossis lwj.
Embalmment - yog kev khaws cia ntawm lub cev tuag los ntawm kev kho nrog tshuaj balsam thiab tshuaj thiab lwm yam tshuaj.
(kom khaws cov organic lub cev, siv cov khoom khaws cia.)
• Kev txuag yog siv los yog siv tsawg. Kev khaws cia yog khaws cia lossis khaws yam uas twb muaj lawm.
