Ukuhlolwa kweendondo zelanga
1. Umgaqo-siseko we-lens ye-UV yokubona ukuhanjiswa kwe-UV Umlinganiselo wokudluliselwa kweelensi zelanga awukwazi ukucutshungulwa njengomlinganiselo olula we-spectral transmittance kubude be-wavelength nganye, kodwa kufuneka ifunyanwe ngokudityaniswa okulinganiselweyo kwe-spectral transmittance ngokobunzima ...Funda ngokugqithisileyo -
Isakhelo sokutofa samehlo
1. Imathiriyeli yokutofa Inkqubo yokubumba yokutofa kukunyibilikisa irayisi yeplastiki (ubukhulu becala iPC, intsimbi yeplastiki, i-TR), kunye nokuyitofa kwi-mold ukuze iphole.Iingenelo zizinzo oluphezulu lwe-dimensional yebhetshi yonke, isantya sokusebenza ngokukhawuleza, kunye nexabiso eliphantsi lilonke.Ububi kukuba uninzi lwe...Funda ngokugqithisileyo -
Izixhobo zetsimbi kwiifreyimu zemiboniso
1. Izinto ezenziwe ngegolide: Kuthatha isilika yegolide njengesiseko, kwaye umphezulu wayo ugqunywe ngumaleko wegolide evulekileyo (K).Kukho imibala emibini yegolide evulekileyo: igolide emhlophe kunye negolide ephuzi.A. igolide Le yintsimbi yegolide ene-ductility elungileyo kwaye phantse akukho discoloration oxidative.Kuba igolide esulungekileyo (24K) ...Funda ngokugqithisileyo -
Indlela yokukhetha izibuko zelanga ezifanelekileyo?
1) Zonke iiglasi zelanga zi-anti-ultraviolet.Ayizizo zonke iiglasi ezichasene ne-ultraviolet.Ukuba unxibe "izibuko zelanga" ezingekho kwi-ultraviolet, iilensi zimnyama kakhulu.Ukuze ubone izinto ngokucacileyo, abafundi baya kwanda ngokwemvelo, kwaye imitha ye-ultraviolet engaphezulu iya kungena emehlweni kwaye amehlo aya kuba ...Funda ngokugqithisileyo -
Iingcebiso zokusebenzisa iindondo zelanga
I-1) Kwiimeko eziqhelekileyo, i-8-40% yokukhanya ingangena kwiiglasi zelanga.Uninzi lwabantu lukhetha i-15-25% yezibuko zelanga.Ngaphandle, iiglasi ezininzi eziguqula umbala zikolu luhlu, kodwa ukukhanya kokukhanya kweeglasi ezivela kubavelisi abahlukeneyo kuyahluka.Iiglasi ezitshintsha umbala omnyama zinokungena ...Funda ngokugqithisileyo -
