Kev siv lub ntsuas hluav taws xob thiab ntsuas ntsuas ntawm UV ntsuas
1. Lub hom phiaj ntawm qhov kev sim:
1. Nkag siab lub tswv yim ntawm irradiance thiab kawm siv lub ntsuas irradiance.
2. Nkag siab txog qhov feem ntawm ultraviolet rays ntawm qhov sib txawv ntawm lub teeb.
3. Kawm los ntsuas qhov ntsuas ultraviolet irradiance.
2. Kev sim lub hauv paus ntsiab lus:
Lub teeb pom kev muaj qee yam ntawm ultraviolet rays. Tus nqi thiab kev faib ua feem ntawm cov hluav taws xob ultraviolet yog qhov tseem ceeb heev rau kev khaws cia ntawm kab lis kev cai relics. Ultraviolet irradiance meter yog siv los ntsuas cov ntsiab lus ntawm ultraviolet rays.
3. Cov ntaub ntawv sim:
Irradiance meter, lub teeb qhov chaw, meter stick, thiab lwm yam.
4. Cov ntsiab lus sim:
1. Ntsuas qhov kev siv ntawm ultraviolet rays nyob rau hauv ntau qhov chaw sab hauv tsev thiab sab nraum zoov.
2. Ntsuas qhov kev siv ultraviolet ntawm cov teeb pom kev sib txawv ntawm qhov deb, thiab suav nws qhov piv.
5. Cov teeb meem xav tau kev saib xyuas:
1. Thaum siv lub ntsuas ntsuas irradiance, xyuam xim rau kev xaiv ntawm kev sojntsuam thiab cov nyees khawm, thiab qhov kev txiav txim ntawm cov iav los ntawm loj mus rau me me.
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 kub hnyiab.
6. Cov kauj ruam sim:
1. Ntsuas qhov kev siv ultraviolet nyob rau hauv ntau qhov chaw sab hauv tsev thiab sab nraum zoov, thiab ntsuas cov ntaub ntawv tsis muaj iav shading, ib txheej ntawm iav shading thiab ob txheej iav shading ntawm lub 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 ultraviolet rays.
4. Ntsuas qhov kev siv ultraviolet ntawm 20cm ntawm 18W lub teeb txuag hluav taws xob, thiab xam qhov feem ntawm cov hluav taws xob ultraviolet.
5. Sib piv cov ultraviolet siv ntawm 20cm ntawm ob peb lub teeb, xam qhov piv thiab sib piv.
Lus Cim: Chav tsev ntawm UV piv yog microwatt ib lumen
7. Sim cov kev xav
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. Hauv kev sib piv, lub teeb txuag hluav taws xob zoo dua rau kev teeb pom kev zoo thiab tiv thaiv UV.
