Optical deformation (sebaka sa pitsa)

Optical deformation, e tsejoang hape e le "esita le letheba", ke khanyetso e nyane e mene holim'a khalase.Sebopeho sa eona se boreleli ebile se chitja, ka bophara ba 0.06 ~ 0.1mm le botebo ba 0.05mm.Mofuta ona oa bofokoli ba matheba o senya boleng ba khalase ea optical mme o etsa hore ntho e bonoang e be lefifi, kahoo e boetse e bitsoa "light cross change point".

Litšitiso tsa optical deformation li bakoa haholo-holo ke condensation ea SnO2 le sulfide.Stannous oxide e ka qhibiliha ka har'a mokelikeli 'me e na le ho feto-fetoha ho hoholo, ha stannous sulfide eona e fetoha ho feta.Mouoane oa tsona oa kokobela ebe butle-butle o bokellana mocheso o tlase.Ha e bokellana ho isa bohōleng bo itseng, tlas'a tšusumetso kapa ho sisinyeha ha phallo ea moea, condensed stannous oxide kapa stannous sulfide e tla oela holim'a khalase e sa thatafalang ka ho feletseng 'me e thehe bokooa.Ho feta moo, metsoako ena ea thini e ka boela ea fokotsoa hore e be tšepe ea tšepe ka likarolo tse fokotsang khase e sireletsang, 'me marotholi a tšepe a tla boela a thehe sekoli ka khalase.Ha metsoako ea thini e theha matheba holim'a khalase ka mocheso o phahameng, li-crater tse nyenyane li tla thehoa holim'a khalase ka lebaka la ho fetoha ha metsoako ena.

Mekhoa ea mantlha ea ho fokotsa bofokoli ba optical deformation ke ho fokotsa tšilafalo ea oksijene le tšilafalo ea sebabole.Tšilafalo ea oksijene e tsoa haholo-holo ho tsoa ho oksijene le mouoane oa metsi ka har'a khase e sireletsang le ho lutlang ha oksijene le ho hasana ka har'a lekhalo la thini.Tin oxide e ka qhibiliha ka har'a thini e metsi 'me ea fetoloa hore e be khase e sireletsang.oxide e ka khase e sireletsang e bata 'me e bokelloa holim'a sekoahelo sa bate ea thini ebe e oela holim'a khalase.Khalase ka boeona e boetse ke mohloli oa tšilafalo ea oksijene, ke hore, oksijene e qhibilihisitsoeng ka har'a mokelikeli oa khalase e tla phonyoha ka bateng ea tin, e tla boela e oxidize thini ea tšepe, 'me mouoane oa metsi holim'a khalase o tla kena sebakeng sa ho hlapa. , eo hape e eketsang karolo ea oksijene ka khase.

Tšilafalo ea sebabole ke eona feela e tlisoang ka bateng ea masenke ka khalase e qhibilihisitsoeng ha ho sebelisoa naetrojene le hydrogen.Karolong e ka holimo ea khalase, hydrogen sulfide e lokolloa ka har'a khase ka sebōpeho sa hydrogen sulfide, e sebetsanang le tin ho etsa stannous sulfide;Karolong e ka tlaase ea khalase, sebabole se kena ka har’a thini e mokelikeli ho etsa stannous sulfide, e qhibilihang ka har’a thini e metsi ebe e fetoha khase e sireletsang.E ka boela ea kokobela le ho bokella holim'a bokaholimo ba sekoahelo sa bate ea thini ebe e oela holim'a khalase ho etsa matheba.

Ka hona, e le ho thibela ketsahalo ea likoli tse teng, ho ke ke ho hlokahala hore ho sebelisa phahameng-khatello e sireletsa khase ho hloekisa condensate ea oxidation le sulfide-potlana banyalani ba holim'a thini bath ho fokotsa deformation optical.
