Cov ozone hauv tus ozone txheej absorbs 97-99% ntawm tag nrho cov lub ultraviolet lub teeb uas hla mus rau hauv tus stratosphere.
Hauv qhov no, qhov twg ntawm lub ntiaj teb huab cua txwv tsis pub muaj hluav taws xob puas tsuaj?
Ozone nyob rau hauv Stratosphere Ozone thiab oxygen molecules nyob rau hauv lub stratosphere absorb ultraviolet lub teeb los ntawm lub hnub, muab ib daim thaiv npog uas. tiv thaiv qhov no hluav taws xob dhau mus rau qhov Lub ntiaj teb nto.
Kuj Paub, ntau npaum li cas UV teeb ua lub ozone txheej lim tawm? Ozone absorbs ntau tshaj 99 feem pua UV -C rays -- qhov txaus ntshai tshaj plaws ntawm spectrum. Ozone absorbs txog 90 feem pua ntawm cov UV -B rays - tab sis 10 feem pua uas ua rau nws dhau los yog qhov tseem ceeb hauv kev ua rau tshav ntuj kub thiab ua rau mob qog noj ntshav. Ozone absorbs txog 50 feem pua ntawm cov UV -A rays.
Ua li no, cov kab hluav taws xob twg yog absorbed tag nrho hauv qhov chaw?
Lub ozone txheej los yog ozone shield yog ib cheeb tsam ntawm lub ntiaj teb lub stratosphere uas nqus feem ntau ntawm lub hnub lub ultraviolet hluav taws xob.
Lub wavelengths twg yog thaiv los ntawm lub ntiaj teb huab cua?
Hmoov zoo rau lub neej Lub ntiaj teb , peb huab cua thaiv cov hluav taws xob hluav taws xob tsis zoo xws li x-rays, gamma rays thiab feem ntau ntawm ultraviolet rays. Cov huab cua kuj absorbs feem ntau ntawm infrared hluav taws xob uas ncav cuag lub Lub ntiaj teb los ntawm qhov chaw.
