Daj daj huab tshwm sim los ntawm qhov muaj nitrogen dioxide qee zaum pom nyob hauv nroog nrog huab cua siab ua paug qib. Liab, txiv kab ntxwv thiab huab liab tshwm sim yuav luag tag nrho ntawm hnub sawv thiab hnub poob thiab yog qhov tshwm sim ntawm qhov tawg ntawm tshav ntuj los ntawm qhov chaw.
Ua li no, lub ntuj puas liab vim muaj kuab paug?
Nws yog feem ntau sau tias ntuj thiab manmade hmoov av thiab ua paug ua rau muaj yeeb yuj hnub sawv thiab hnub poob. Cov huab cua huv yog, qhov tseeb, cov khoom tseem ceeb uas muaj rau cov xim ci ntsa iab sunrises thiab sunsets. Yuav kom nkag siab tias yog vim li cas qhov no yog li ntawd, ib tug yuav tsum tsuas yog nco qab npaum li cas ntuj xim yog tsim.
Tsis tas li ntawd, cov xim hauv lub hnub poob puas tshwm sim los ntawm kev ua qias tuaj? Yog nws lub azure ntawm siab tav su los yog txiv kab ntxwv ci ntawm tsaus ntuj, lub xim Lub ntuj tsim los ntawm lub hnub ci cuam tshuam nrog cov molecules hauv huab cua, feem ntau nitrogen thiab oxygen, ua rau nws yuav tsum deflected nyob rau hauv tag nrho cov lus qhia, ib tug phenomenon hu ua Rayleigh tawg.
Ib yam li ntawd, tej zaum koj yuav nug, puas yog huab ua los ntawm cov pa phem?
Nyob ntawm lawv hom, huab tuaj yeem muaj cov cua qhuav sib xyaw nrog cov kua dej ntws, cov dej khov, lossis ob qho tib si. Thin, sab saud huab (cirrus) yog ua ntawm me me particles.
Cov pa phem cuam tshuam li cas rau huab tsim?
Kev nce hauv kev ua qias tuaj qhov tseeb cuam tshuam huab tsim . Yog tias cov pa phem yog aerosolized lawvreflect lub hnub ci thiab huab npog nce, yog tias lawv nqus nws huab yog dissipated. Ib txhia cov pa phem (chemicals) sib tov nrog cov huab thiab formatmospheric molecules uas tsim tej yam xws li acid nag.

Dab tsi yog lub zog uas tuaj yeem tshwm sim ntawm qhov chaw ua si los ua kom cov khoom pib txav mus los?
Kev sib txhuam. Thaum lub ntiajteb txawj nqus yog ib qho tseem ceeb ntawm physics rau qhov chaw ua si swb, kev sib txhuam yog qhov tseem ceeb sib npaug. Kev sib txhuam ua haujlwm tiv thaiv lub ntiajteb txawj nqus kom qeeb tus neeg qhovntsej thiaj tsis mob ntawm tus swb. Kev sib txhuam yog ib qho quab yuam uas tshwm sim thaum twg ob yam khoom rub tawm rau ib leeg, xws li swb thiab ib tus neeg lub nraub qaum
Koj puas tuaj yeem qhia los ntawm cov kev nqus dej no seb lub teeb liab puas ua haujlwm zoo hauv kev tsav tsheb photosynthesis?
Ib qho tsis tuaj yeem qhia los ntawm daim duab no, tab sis vim tias chlorophyll ib lub teeb liab, peb tuaj yeem kwv yees tias nws yuav ua tau zoo hauv kev tsav tsheb photosynthesis. Cov xim no muaj peev xwm nqus tau ntau lub teeb ntawm lub teeb (thiab yog li ntau lub zog) dua li chlorophyll ib leeg tuaj yeem nqus tau
Tus qauv yuav pab nrhiav qhov tshwm sim ntawm qhov kev tshwm sim sib xyaw li cas?
Lub ntsiab lus ntawm Qhov Muaj Peev Xwm Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej yog ib qho uas muaj ntau tshaj li qhov ua tau. Kev txiav txim siab qhov yuav tshwm sim ntawm qhov kev tshwm sim sib xyaw suav nrog kev nrhiav cov lej ntawm qhov tshwm sim ntawm tus kheej cov xwm txheej thiab, yog tias tsim nyog, tshem tawm qhov muaj feem sib tshooj
Qhov txheej twg yog huab cua tshwm sim feem ntau tshwm sim?
Troposphere. Lub troposphere (los ntawm Greek: tropein - hloov, ncig lossis sib xyaw) yog txheej qis tshaj plaws ntawm lub ntiaj teb huab cua. Feem ntau ntawm huab cua phenomena, systems, convection, turbulence thiab huab tshwm sim nyob rau hauv no txheej, tab sis tej zaum yuav mus rau hauv lub qis feem ntawm thestratosphere
Vim li cas cov kab mob Gram tsis zoo tshwm liab liab thaum cov kab mob Gram zoo pom ntshav liab?
Gram zoo hlwb stain ntshav vim lawv cov peptotidoglycan txheej yog tuab txaus, txhais tau tias tag nrho cov kab mob Gram zoo yuav khaws lawv cov stain. Gram tsis zoo hlwb stain liab vim lawv muaj ib tug nyias peptidoglycan phab ntsa, thiab lawv yuav tsis khaws ib yam ntawm cov ntshav stain los ntawm crystal violet
