Dichroic iav. Nws zoo li cas thiab qhov twg nws yog siv

Nyob rau hauv xyoo tsis ntev los no, tsis muaj kos duab kos duab nyob rau hauv seem ntawm glassware los yog hniav nyiaj hniav kub los ntawm kub thiab nyiaj tsis tau ua yam tsis tau ua haujlwm ntawm daim duab thiab cov khoom siv koob yees duab, hauv cov creation ntawm uas tus txawj siv cov dichroic iav. Nyob rau hauv no ua ke ntawm cov lus muaj tej yam yees siv, raws li nyob rau hauv cov ntaub ntawv nws tus kheej. Cov npe ntawm cov khoom qub uas niaj hnub thiab niaj hnub, cov cuab yeej siv tau zoo tuaj yeem ua ke. Dichroic iav - yog dab tsi? Los ntawm dab tsi txhais tau hais tias tus txiv neej tswj kom ua li ntawd tiag tiag natural uniqueness ntawm man-made cov ntaub ntawv? Peb yuav sim teb cov lus nug no.

Cov khawv koob ntawm iav

Thawj vases, bowls, jugs thiab lwm yam iav tau ntau kub tshaj kub. Cov keeb kwm keeb kwm ntawm cov khoom no yog mus nrhiav tau nyob rau hauv ancient Rome. Cov kos duab ntawm mosaic masters, iav carvers, iav blowers thiab ancient, thiab niaj hnub ltalis surprises, fascinates thiab amazes. Txij ntawm lub kaum tsib xyoo pua, lub secrets ntawm Venetian glassmakers vau rau hauv lub teb chaws Europe. English, Spanish, Czech, German, Fabkis masters tau sim mus cuag tau qib ntawm cov xib fwb mus hauv cov kob ntawm Murano nyob rau hauv lub khob thiab huv si technology. Cov kev vam meej yog, tab sis tsis muaj leej twg yuav tshaj qhov Venetian. Dichroic iav yog twb niaj hnub khoom ntawm qhov tseeb achievements nyob rau hauv qhuav ntawm cov ntaub ntawv ancient. High-tech, tab sis qhov no tsis yog devoid of romance nyob rau hauv cov ntaub ntawv ntawm ntog mus rau hauv lub tes ntawm tiag tiag ntxias.

Ob xim nyob rau hauv qhov

Dichroic hniav yuav hloov xim. Lawv cov prototypes kuj tau txais los ntawm cov xib fwb ntawm lub era ntawm Venetian iav renaissance. Feem ntau, "dichroism" yog qhov tshwm sim kho qhov muag. Lub sijhawm txhais lus los ntawm cov lus Greek: "di" - ob thiab "chrome" - xim, i.e. "ob colors". Muaj tshuaj yeeb dej caw thiab cov khoom siv tuaj yeem cuam tshuam tsis tau tib lub sijhawm, thiab cia lwm tus dhau. Outwardly nws zoo li hla, flicker thaum saib lawv los ntawm ntau cov ces kaum ntawm saib. Txhua tus neeg pom li cas tus miv lub qhov muag ci, ua li cas lub feathers nyob rau Tail ntawm peacock thiab tis ntawm loj May beetles shimmered nyob rau hauv xiav los yog ntsuab. Ib qho piv txwv ntawm dichroism yog cov xim ntawm kev nyab xeeb ntawm npauj npaim Margot. Nws yog hu ua ib feem saum ntuj ceeb tsheej hauv ntiaj teb - qhov no yog qhov sib txawv xim xiav xim. Thiab qhov zoo tshaj plaws yog hais tias lub tis lawv tus kheej yog cov tsis muaj kob. Hloov cov xim tsis yog vim pigmentation, tab sis vim cov khoom kho qhov muag ntawm nanofiltrations ntawm ntau daim duab nyob rau hauv lub me plaub tshaj plaws uas npog qhov saum npoo ntawm tis ntawm kev zoo nkauj. Cov qub cov khoom ntawm cov txheej txheej zoo tshaj plaws ntawm calcium carbonate, npog lub hlaws, ua rau nws hlaws. Xwm muaj ntau yam piv txwv. Tibneeg ntse thiab kev ua haujlwm tau tsim los tsim ib qho khoom siv nrog cov khoom zoo sib xws.

Rau dab tsi, los ntawm dab tsi

Pib, tus neeg muaj lub cim nanocoating rau cov iav iav yog hauv Tebchaws Asmeskas Kev Ua Lag Luam thiab Chaw Tswjfwm. Dichroic cov ntxaij lim dej, cov khoom qub, tsom iav siv dav hauv cov tub rog thiab kev lag luam. Cov ntxaij lim dej no ua haujlwm ua cov tsom iav tshwj xeeb, qhia txog lub teeb ntawm cov spectrum uas tsis yog kev txaus siab. Lub thickness ntawm cov multilayer txheej rau lawv - yog tsis ntau tshaj li tus wavelength ntawm lub teeb. Cov khaubncaws sab nraud povtseg ntawm nanofilms ntawm oxides los yog nitrides ntawm cov khoom muaj nqis thiab semiprecious hlau. Siv cov khoom sib txuas ntawm txhuas, chromium, silicon, zirconium, magnesium, titanium, kub, nyiaj. Txhua yam tshuaj pleev txawv yog qhov tshwj xeeb thiab tsis tsim nyog. Qhov no yog li cas rau cov neeg muaj kev thaj yeeb muaj tswv yim - cov yeeb yaj kiab, tus tsim, cov kws kho hniav, cov hniav nyiaj hniav kub - siv cov khoom siv ntawm cov khoom no rau txhua txoj haujlwm. Qhov loj tshaj tis tau txais los ntawm kev txais khoom plig los ntawm dichroic iav thiab exquisite hniav nyiaj hniav kub. Cov ntaub ntawv thiab tshwj xeeb tshaj yog ua hauj lwm nyob rau hauv lub txau ntawm dichroic yog heev kim, yog li ntawd tus nqi ntawm cov khoom kos duab sib raug mus rau cov nqi.

Dichroic txau

Cov cuab yeej ntawm daim ntawv thov dichroic txheej yog txawv. Lub hauv paus ntsiab lus zoo ib yam li cov plasma saib. Nyob rau hauv lub Chamber ntawm ib tug tshwj xeeb kev tsim kho, reminiscent ntawm lub haveronic collider, rhuab mus rau ob puas degrees, tsim ib lub tshuab nqus tsev. Nyob rau hauv xws li tej yam kev mob, ib tug ntshav tshwm nyob rau saum npoo ntawm metallic compounds. Electron phom tua tawm ntawm electrons los ntawm nws, uas khom ntawm iav nto. Qhov txheej yog muab los ntawm fusing nws mus rau hauv iav ntawm atomic qib thiab yog li ntawd heev ruaj. Nyob rau hauv no txoj kev, siv ntau yam sib txuas ntawm cov saum toj no co, nws yog ua tau kom tau ob peb puas ntxoov ntawm lub teeb lim. Mus ntxiv rau ntau yam, kev siv cov iav ntawm txawv xim raws li lub hauv paus rau spraying lub iav tau raug siv.

Vim li cas iav

Iav raws li lub hauv paus yog tsis xaiv across. Qhov no yog ib qho khoom plig zoo nkauj. Iav huab cua txias sai sai, tsis muaj sij hawm los ua kom pob txha. Lub ntsiab tivthaiv rau ntawm cov iav yog silicon dioxide. Cov cuab yeej siv ntawm ntau lawm thiab ntau yam khoom siv los txiav txim siab xws li cov yam ntxwv ua rau kev tsis sib haum, tawv, kub ua hauj, tsis kam ua dej thiab tshuaj, thiab ntxiv rau. Rau sputtering deposition dichroic siv khoom borosilicate iav muaj ib tug siab melting point. Qhov tshwm sim ntawm cov xim, ci, qhov tseem ceeb yog nyob ntawm cov khoom ntawm iav, ua ke nrog cov hlau oxides, cov thickness thiab cov nanolayers ntawm kev sib ntxub.

Muaj cib fim rau kev xav

Masters ntawm fusing thiab lampwork tau ntev txaus siab rau lub meej mom ntawm man-made khoom, tsis zoo nyob rau hauv kev zoo nkauj rau precious thiab tsawg pob zeb. Tsim ib lub khob dichroic nrog koj txhais tes tsis muaj cov cuab yeej tshwj xeeb tsis yooj yim sua. Tam sim no qhov no yuav tsum tsis txhob ua. Hauv cov kev lag luam tshwj xeeb, muaj ntau hom kev kos duab nyob rau hauv daim ntawv ntawm tag nrho cov ntawv los yog khwv nyiaj tsawg dua. Los tsim cov khoom plig, mosaics los ntawm cov iav txawv, koj yuav tsum coj mus rau hauv lawv tus account lawv nrog lub thermal expansion coefficient. Qhov kev qhia ntawm lub iav yuav tsum tau sau los ntawm lub khw. Nws yog ib qho tseem ceeb uas ESR yog tib yam rau cov khoom sib txawv, yog li ntawd cov hauj lwm ntawm daim thiab cov thawv thaum lub caij txias tsis tawg thiab tsis tawg. Rau cov masters, cov hniav nyiaj hniav kub nrog lawv tus kheej tes, hauv cov khw muag khoom muab dichroic iav rau hauv daim ntawv ntawm cov hlaws dai thiab cabochons. Dichroic hlaws dai pob txha, kheej kheej, oblong. Cabochons - nyob rau hauv daim ntawv ntawm ntau qhov ntau thiab tsawg ntawm geometric duab, tee, hnub qub thiab ntau yam txawv duab. Nyob rau hauv tag nrho cov no ntau yam ntawm cov ntaub ntawv, ib tug txawm ntau dav ntau yam ntawm cov ntsiab lus muaj khov.
