Yuav ua li cas xaiv lub tshuab ntsuas UV teeb

Yog tias koj yuav tsum pib kuaj UV, tab sis koj tsis paub yuav xaiv ib qho twgUV lub teeb kuaj tshuabuas tiag tiag ua tau raws li koj qhov yuav tsum tau ua, ces kab lus no yuav muab cov lus teb rau koj.

Ultraviolet (UV) hluav taws xob muaj nyob ib puag ncig peb, thiab nws tuaj yeem ua rau muaj kev phom sij rau peb kev noj qab haus huv thiab ib puag ncig. Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tsum tau ua qhov kev ntsuam xyuas UV kom nkag siab txog qhov cuam tshuam ntawm UV rays thiab txhim kho txoj kev tiv thaiv zoo. Nov yog qee qhov tseem ceeb tshaj plaws rau kev kuaj UV.

Dab tsi yog qhov tseem ceeb tshaj plaws rau kev kuaj UV?

1. Wavelength
Lub wavelength ntawm UV hluav taws xob yog ib qho tseem ceeb parameter vim tias nws txiav txim siab hom UV hluav taws xob thiab nws cov teebmeem ntawm cov kab mob nyob. UV hluav taws xob tau muab faib ua peb pawg raws li wavelength - UVA (320-400 nm), UVB (290-320 nm), thiab UVC (100-290 nm). UVC feem ntau yog nqus los ntawm peb cov huab cua, tab sis UVA thiab UVB tuaj yeem nkag mus rau peb cov tawv nqaij thiab muaj qhov sib txawv ntawm peb txoj kev noj qab haus huv.

2. Irradiance
Lub irradiance ntawm UV hluav taws xob txiav txim siab qhov kev siv ntawm UV raug thiab ntau npaum li cas UV hluav taws xob absorbed los ntawm ib yam khoom. Kev ntsuas qhov irradiance yuav tsum muaj lub ntsuas hluav taws xob, thiab nws yog qhov tseem ceeb kom nkag siab txog qhov sib txawv ntawm cov hluav taws xob los txiav txim seb qhov cuam tshuam ntawm UV hluav taws xob rau cov kab mob nyob.

3. Lub Sijhawm Tawm
Lub sij hawm uas lub cev raug UV hluav taws xob yog qhov tseem ceeb rau kev kuaj. Lub sij hawm raug txiav txim siab qhov cuam tshuam ntawm UV hluav taws xob thiab ntau npaum li cas kev puas tsuaj UV hluav taws xob tuaj yeem ua rau lub sijhawm.

4. Kub thiab av noo
Kub thiab av noo tuaj yeem cuam tshuam qhov cuam tshuam ntawm UV hluav taws xob rau cov kab mob nyob. Qhov kub thiab av noo sib txawv tuaj yeem hloov pauv qhov nqus thiab tawg ntawm UV hluav taws xob, ua rau ntau qib ntawm UV raug.

5. Hom nto
Hom nto raug UV hluav taws xob txiav txim siab npaum li cas ntawm UV hluav taws xob absorbed, reflected, los yog kis. Cov ntaub ntawv sib txawv muaj qhov sib txawv ntawm UV nqus thiab cuam tshuam cov khoom, thiab nws yog ib qho tseem ceeb uas yuav tsum xav txog hom nto thaum kuaj cov teebmeem ntawm UV hluav taws xob.
