Haze qhia qhov feem pua ntawm cov teeb pom kev zoo uas cuam tshuam los ntawm txoj kab ncaj nraim ntawm lub kaum sab xis ntawm ntau dua 2.5 degree. Piv txwv li, yog tias 60 feem pua ntawm cov teeb pom kev ncaj qha yog deflected, qhov no qhia tau tias yog qhov feem pua ntawm qhov pom ntawm 60 feem pua.
Lub diffusion ntawm lub teeb yog qhia los ntawm qhov haze factor. Qhov siab dua qhov haze, qhov loj dua qhov diffusion. Float iav tsis diffuse lub teeb thiab yog li ntawd muaj qhov kub hnyiab ntawm 0 feem pua . Feem ntau, qhov siab dua qhov haze nqi, qhov qis dua hemispheric lub teeb kis tau tus mob (hem. LT). Qhov no txhais tau hais tias nyob rau hauv cov ntaub ntawv ntawm ib tug tsawg haze lub (hem.) LT yog siab tshaj rau ib tug siab haze. Kev sib xyaw kom raug ntawm cov nqi hluav taws xob thiab (hem) LT nyob ntawm cov qoob loo, kev nyab xeeb thiab cov tswv yim loj hlob.
Yuav ua li cas paub txog tus nqi haze ntawm ib lub iav diffuse?
Txoj Kev 1: Los Ntawm Qhov Muag liab qab
Peb tuaj yeem siv lub laser pointer rau irradiate ib sab ntawm lub iav, thiab saib qhov loj ntawm lub teeb thiab duab ntxoov ntxoo cheeb tsam tsim los ntawm lub teeb hla lub iav thiab tawg mus rau phab ntsa, thiaj li yuav muaj kev txiav txim siab ntxhib ntawm qhov kub hnyiab ntawm tus nqi. lub iav. Tab sis txoj kev no tsis tuaj yeem paub qhov tseeb tus nqi ntawm haze.

Txoj Kev 2 Kev Ntsuas Cov Khoom Siv
Cov iav raug sim nrog kev pab los ntawm cov cuab yeej tshaj lij kom tau txais qhov kub hnyiab ntawm cov iav. Ntau hom, txawv thicknesses, thiab cov qauv sib txawv ntawm cov iav diffuse muaj qhov sib txawv haze qhov tseem ceeb.

Peb lub tuam txhab nyuam qhuav yuav lub diffuse iav haze tester los pab txhawb kev kuaj haze ntawm cov khoom sib txawv ntawm cov iav tsom iav kom ntseeg tau tias muaj kev ruaj ntseg, qhov tseeb, thiab kev ua tau zoo ntawm cov khoom tsis zoo.
