Siv cov ntsuas irradiance thiab UV ntsuas ntsuas ntsuas
Kev sim lub hom phiaj:
1. Nkag siab lub tswv yim ntawm irradiance thiab kawm siv lub ntsuas irradiance.
2. Nkag siab txog UV piv ntawm cov teeb pom kev sib txawv.
3. Kawm los ntsuas qhov ntsuas ultraviolet irradiance.
Kev sim txoj cai:
Lub teeb pom kev muaj qee yam ntawm cov hluav taws xob ultraviolet, thiab tus nqi thiab feem ntau ntawm cov hluav taws xob ultraviolet tseem ceeb heev rau kev khaws cia ntawm kab lis kev cai relics. Kev siv ultraviolet irradiance meters los ntsuas cov ntsiab lus ntawm cov hluav taws xob ultraviolet.
Cov ntaub ntawv sim:
Irradiance meter, lub teeb qhov chaw, meter kav, thiab lwm yam.
Cov ntsiab lus sim:
1. Ntsuas qhov sib zog ntawm cov hluav taws xob ultraviolet nyob rau hauv qhov sib txawv sab hauv tsev thiab sab nraum zoov.
2. Ntsuas qhov UV siv ntawm cov teeb pom kev sib txawv ntawm qhov deb thiab suav lawv qhov piv.
Cov kev ceev faj:
1. Thaum siv lub ntsuas ntsuas irradiance, xyuam xim rau kev xaiv ntawm kev sojntsuam thiab cov nyees khawm, thiab xyuam xim rau qhov kev txiav txim ntawm cov iav los ntawm sab saum toj mus rau hauv qab.
2. Qhov kev sojntsuam ntawm irradiance meter yuav tsum yog perpendicular rau lub teeb.
3. Thaum hloov lub teeb ci, xyuam xim rau qhov kub ntawm lub teeb kom tsis txhob * *.
Kev sim cov kauj ruam:
1. Ntsuas qhov kev siv ultraviolet ntawm qhov sib txawv ntawm sab hauv tsev thiab sab nraum zoov, thiab ntsuas cov ntaub ntawv tsis muaj iav thaiv, ib txheej iav thaiv, thiab ob txheej iav thaiv ntawm qhov rais. Cov txiaj ntsig ntsuas tau qhia hauv Table 1.
2. Ntsuas qhov kev siv ultraviolet ntawm 20cm ntawm 40W incandescent teeb thiab xam qhov feem ntawm cov hluav taws xob ultraviolet.
3. Ntsuas qhov kev siv ultraviolet ntawm 20cm ntawm 100W incandescent teeb thiab xam qhov feem ntawm cov hluav taws xob ultraviolet.
4. Ntsuas qhov kev siv ultraviolet ntawm 20cm ntawm 18W lub teeb txuag hluav taws xob thiab suav qhov feem ntawm cov hluav taws xob ultraviolet.
5. Sib piv cov UV siv ntawm 20cm ntawm ob peb lub teeb ci, xam qhov sib piv, thiab sib piv.
Kev sim Reflection
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm cov teeb ci incandescent thiab lub teeb txuag hluav taws xob sib txawv. Raws li cov teeb ci incandescent, lawv yeej zoo ib yam tshwj tsis yog qhov sib txawv ntawm qhov ntau. Piv txwv li, lub teeb txuag hluav taws xob zoo dua rau kev teeb pom kev zoo thiab tiv thaiv UV.
