Hauv cov ntsiab lus yooj yim, rau feem ntau ntawm cov tsev cog khoom siv rau kev cog qoob loo,ultra- iav ntshiabyog qhov kev xaiv zoo dua thiab muaj kev tshaj lij tshaj li kev tiv thaiv- iav diffusion.
Lub ntsiab lus xaus los ua ntej
Ultra- iav ntshiab: Nws yog cov khoom siv tshaj lij tsim rau kev ua liaj ua teb tsev cog khoom. Nws lub hom phiaj tseem ceeb yog ua kom lub teeb pom kev zoo tshaj plaws, txhawb nqa photosynthesis hauv cov nroj tsuag, thiab txhim kho cov qoob loo zoo thiab tawm los.
Anti- iav diffusion (tseem hu ua embossed iav): Nws yog tsuas yog siv nyob rau hauv kev tsim kho, xws li chav dej thiab partitions, nrog rau lub hom phiaj tseem ceeb ntawm kev tso cai rau lub teeb hla tab sis tsis dluab, thiab tiv thaiv tus kheej. Nws cov khoom kho qhov muag muaj kev puas tsuaj rau cov nroj tsuag kev loj hlob.
Vim li cas lub teeb transmittance thiab lub teeb hom tseem ceeb heev?
Lub photosynthesis ntawm cov nroj tsuag nyob ntawm lub zog nyob rau hauv tshav ntuj (feem ntau yog pom spectrum ntawm 400-700nm, hu ua photosynthetically active hluav taws xob PAR). Lub teeb transmittance ncaj qha txiav txim siab npaum li cas hnub ci zog nkag mus rau hauv tsev cog khoom.
Lub teeb xa hluav taws xob: Lub teeb xa hluav taws xob ntawm ultra- iav ntshiab yog tshaj 5% siab dua li cov iav zoo tib yam, uas txhais tau hais tias ntau teev hnub ci nkag mus rau hauv tsev cog khoom txhua hnub. Nyob rau tib lub sijhawm, qhov no muaj kev cuam tshuam loj heev rau kev loj hlob ntawm cov qoob loo.
Direct light vs. diffused lub teeb:
Lub teeb ncaj qha: Nrog lub zog muaj zog, nws tuaj yeem nkag mus rau hauv cov canopy thiab ncav cuag nruab nrab thiab qis ntawm cov nroj tsuag, ua lub zog tseem ceeb rau photosynthesis. Nws yog ib qho tseem ceeb tshwj xeeb rau lub teeb -kev hlub cov qoob loo xws li txiv lws suav, dib, thiab paj.
Diffused lub teeb: Zog dispersion. Txawm hais tias lub teeb diffused tuaj yeem tiv thaiv kev kub nyhiab thiab sib npaug ntawm lub teeb hauv qee qhov xwm txheej (xws li hauv thaj chaw uas muaj hnub ci siab), qhov no los ntawm kev siv tag nrho lub teeb siv. Lub teeb diffused tsim los ntawm anti- iav diffusion yog "passive thiab tsis muaj txiaj ntsig" tawg, uas tsis tshua muaj peev xwm tswj tau thiab tshawb fawb ntau dua li cov iav tshwj xeeb tsim los yog lub hnub ci nets.
Yog li ntawd, siv los tiv thaiv- iav diffusion yog sib npaug los txuas ntxiv daim ntaub tuab thiab qias neeg rau lub tsev cog khoom, nkim lub hnub ci zog dawb.
Daim ntawv thov tshwj xeeb scenarios
Anti- iav diffusion yog tsis muaj txiaj ntsig tag nrho hauv tsev cog khoom, tab sis nws yuav tsum tsis txhob siv los ua cov khoom tseem ceeb saum toj kawg nkaus. Nws muaj peev xwm thov scenarios yog:
Tsev cog khoom sab phab ntsa: Siv los ua cov txheej txheem enclosure nyob ib puag ncig, lawv tuaj yeem ua kom muaj qee qhov teeb pom kev zoo thaum thaiv kev pom sab nraud, tiv thaiv cov qoob loo sab hauv thiab cov khoom siv, thiab muaj tus nqi qis.
Tsis yog- thaj chaw tsim khoom: Kev faib khoom siv rau thaj chaw ua haujlwm thiab chaw so.
Kev xaiv siab dua: ultra-dawb anti-reflective (AR) iav
Qhov no yog tam sim no cov khoom nyiam rau siab - tsev cog khoom kawg. Raws li ultra- iav ntshiab, nws txo cov teeb pom kev ntawm lub iav nto los ntawm cov txheej txheem txheej txheem (los ntawm 8% mus rau qis dua 2%), ntxiv rau qhov teeb pom kev xa mus rau ntau dua 97%. Nws kuj muaj tus kheej zoo heev - tu muaj nuj nqi thiab tuaj yeem tswj lub teeb pom kev zoo rau lub sijhawm ntev. Txawm hais tias nws muaj tus nqi siab tshaj plaws, qhov nce hauv cov nyhuv ntau lawm nws coj yog qhov tseem ceeb tshaj plaws.
Cov ntsiab lus thiab cov lus qhia
Ua raws cov zis thiab qhov zoo: Tsis muaj qhov tsis ntseeg txog kev xaiv ultra- iav ntshiab. Qhov no yog ib qho ntawm cov kev nqis peev tseem ceeb tshaj plaws hauv kev tsim khoom. Yog tias cov peev nyiaj txaus, ultra-dawb anti-reflective (AR) iav tau pom zoo.
Nws yog ib qho tsim nyog yuav tsum tsis txhob siv los tiv thaiv - iav diffusion nyob rau sab saum toj lub teeb - xa tawm ntawm cov tsev cog khoom, vim qhov no yuav ua rau txo qis yields thiab poob zoo.
Thaum cov peev nyiaj raug txwv: Txawm tias tsis siv ultra- iav ntshiab, cov iav float zoo tib yam uas muaj lub teeb xa hluav taws xob ntau dua yuav tsum tau xaiv es tsis txhob siv iav los tiv thaiv - diffusion iav.
Xav txog ib puag ncig: Hauv cov cheeb tsam uas muaj teeb pom kev zoo heev (xws li thaj chaw siab thiab sab qaum teb sab hnub poob) qhov chaw kub thiab muaj zog tshav ntuj nyob rau lub caij ntuj sov yuav ua rau kub hnyiab, sab nrauv shading los yog tshwj xeeb tsim cov iav diffused tuaj yeem siv los kho lub teeb, es tsis txhob siv tshuaj tiv thaiv - diffusion iav.
Kuv vam tias qhov kev ntsuam xyuas ntxaws no tuaj yeem pab koj xaiv qhov tsim nyog tshaj plaws!
