Yuav ua li cas txhim khu cov thermal rwb thaiv tsev nyhuv ntawm thermal rwb thaiv tsev hnab

Peb yuav tsum xub to taub lub hauv paus ntsiab lus ntawm rwb thaiv tsev hnab rwb thaiv tsev. Feem ntau, muaj 3 txoj hauv kev. Los ntawm cov qauv ntxeem tau, cov huab cua sab hauv yog khaws cia kom ntau li ntau tau, cov huab cua ntws los tiv thaiv, thiab cov hluav taws xob infrared yog absorbed los ntawm cov xim dawb los yog dub. Cov txheej txheem qhwv yas tau pom zoo los ntawm ib tus phooj ywg yog txhawm rau tiv thaiv huab cua ncig, thiab nws tseem tuaj yeem ua kom sov los ntawm kev txo cov sij hawm qhib lub hau, tab sis cov ntaub qhwv yas yog nplaum heev thiab siv tsis yooj yim, thiab muaj cov ntawv ci txhuas rau. ua npuas ncauj. Lub nam yog los cuam tshuam cov hluav taws xob infrared, txo qhov kub ntawm qhov poob mus rau sab nraud. Peb kuj tuaj yeem ua kom cov txheej txheem ntxeem tau, uas yog txhawm rau ua kom lub thickness ntawm cov rwb thaiv tsev txheej. Yog tias koj xav kom lub thawv muag muag, koj tuaj yeem ntxiv 2 txheej ntawm cov npuas dej, thiab koj tuaj yeem yuav nws ntawm lub khw muag khoom hauv cov kav dej kub hauv lub tsev muag khoom; Yog tias koj tsis quav ntsej txog qhov hardness, koj tuaj yeem siv benzene board nrog qhov ntom ntom dua yog siv los nthuav nws ntawm 6 sab. Lub benzene board yog kaw -cov qauv ntawm tes, thiab nws cov thermal rwb thaiv tsev ua tau zoo dua li ntawm cov npuas dej, thiab nws cov tuab yog ntau dua li ntawm cov npuas dej. Cov ice cream muag ntawm txoj kev siv benzene board kom sov, thiab cov khoom siv hauv tsev muag khoom. Muaj cov khw muag khoom ntawm cov ntaub ntawv thermal rwb thaiv tsev, thiab nyob rau sab qab teb, koj tuaj yeem yuav cov thawv ua npuas ncauj los ntawm cov khoom lag luam hauv dej thiab kho lawv. Ua npuas ncauj yog benzene board. Qhia meej tias benzene board tsis yog - lom, lub npe tag nrho yog polystyrene ua npuas ncauj board, tsis txhob ntshai los ntawm lo lus benzene, nws tsis yog - tshuaj lom thiab yuav tsis volatilize, siv nrog kev ntseeg siab.
