Laser ntxuav ntawm cov pej thuam yog ib txoj kev ntawm kev coj noj coj ua relics tiv thaiv thiab kho dua tshiab siv laser technology. Lub tshuab no siv lub zog siab laser los teeb pom cov pa phem ntawm qhov chaw ntawm tus pej thuam, thiab siv thermal, mechanical thiab photochemical los tshem tawm cov pa phem ntawm qhov khoom. Piv nrog rau kev tu ib txwm siv, kev ntxuav laser tuaj yeem ua kom raug qhov chaw thiab ncav cuag kev ntxuav cov pa phem ntawm micron nplai, tuaj yeem ntxuav cov organic thiab inorganic cov pa phem, thiab yeej tsis tsim cov pa phem ntxiv, muaj qhov zoo ntawm kev txawj ntse tswj, tsis siv neeg ua haujlwm, thiab ntsuab ib puag ncig tiv thaiv.
Daim ntawv thov ntawm laser ntxuav tshuab hauv kev tiv thaiv kab lis kev cai relics pib nyob rau hauv 1970s, thiab cov kws tshawb fawb Asmeskas Asums thiab lwm tus thawj zaug siv laser los ntxuav lub plhaub tawv ua kuab paug rau ntawm pob zeb nto ntawm Venice, thiab paub tseeb tias nws cov nyhuv. Txij thaum ntawd los, laser tu tshuab tau dav siv nyob rau hauv kev tu ntau yam artifacts, nrog rau lub xyoo pua 15th lub vaj huam sib luag paintings, thiab nws txoj kev nyab xeeb thiab kev ua tau zoo tau lees paub los ntawm Fourier transform infrared spectroscopy (FTIR) thiab ua ke roj chromatography-mass spectroscopy (GC-MS). ).
Txoj kev loj hlob thiab kev siv tshuab laser tu tshuab tseem tab tom txhim kho, piv txwv li, kev sim kev tshawb fawb ntawm laser ntxuav cov pa phem nyob rau saum npoo ntawm Yungang Grottoes, thiab kev tshawb fawb ntawm laser ntxuav cov pa phem ntawm cov pob zeb kab lis kev cai relics. Cov kev tshawb fawb no tau pom tias laser tu tshuab tuaj yeem tshem tawm cov khoom paug tawm ntawm qhov chaw ntawm cov kab lis kev cai thaum tiv thaiv lub xeev qub ntawm kev coj noj coj ua.
Kev lag luam tiam sis, laser ntxuav kev lag luam loj hlob ib xyoos ib zaug, yuav tsum tau mus txog 2028, lub ntiaj teb no kev lag luam loj yuav ncav cuag 6.217 billion yuan, yuav tsum nruab nrab txhua xyoo kev loj hlob tus nqi ntawm 6.42% fluctuation. Vim nws cov yam ntxwv zoo ib puag ncig thiab ua tau zoo, laser tu tshuab muaj peev xwm ua lag luam loj, tshwj xeeb tshaj yog nyob rau hauv cov ntsiab lus ntawm lub teb chaws ib puag ncig tiv thaiv cov tswv yim xws li "carbon neutrality" thiab "carbon ncov," kev lag luam xav tau ntawm laser tu yuav tsum tau nce ntxiv. raws li ib yam tshiab ntawm ib puag ncig tus phooj ywg tu tshuab.
Nyob rau hauv cov ntsiab lus, laser ntxuav sculpture yog ib tug npaum thiab ib puag ncig tus phooj ywg tu tshuab uas muaj broad daim ntawv thov kev cia siab nyob rau hauv lub teb ntawm kab lis kev cai relic tiv thaiv thiab kho, thiab raws li cov cuab yeej tsim thiab kev lag luam xav tau loj hlob, laser ntxuav tshuab yuav txuas ntxiv mus ua lub luag haujlwm tseem ceeb hauv daim teb no.
