1 Performance paramita mgbe mkpuchi
N'isiokwu gara aga, anyị webatara ọrụ, ụkpụrụ, ngwanrọ imewe na usoro mkpuchi nkịtị nke ihe nkiri dị mkpa. N'isiokwu a, anyị na-ewebata ule nke parampat mkpuchi mkpuchi. Akụkụ arụmọrụ nke elu nke akụkụ ahụ mgbe mkpuchi na-agụnye Transmittance (Transmittance), Reflectance (R), Absorptance (A), wdg. Na mgbakwunye, absorptance (Transmittance) na ihe ndị ọzọ. Ekwesịrị ịnwale ma nyochaa njirimara mgbasa ozi S (Scatter) nke ihe nkiri ahụ.
The transmittance T bụ oke nke ike ike ọkụ na-agafe na fim ahụ na ike ọkụ merenụ. Ngosipụta R bụ oke ike ike na-egosipụta site na elu mkpuchi na ike ihe merenụ. Absorption A bụ nha nke ike ọkụ nke oyi akwa ihe nkiri na-etinye na ike ọkụ merenụ. Maka paramita atọ ndị a, njikọ ndị a dị:
T + R + A = 1
Ya bụ, nchikota nke transmittance, reflectivity na absorption nke ihe nkiri oyi akwa bụ mgbe niile 1. Nke a pụtara na mgbe ìhè ọkụ na-agafe na akpụkpọ ahụ, akụkụ ya na-agafe, akụkụ ya na-egosipụta pụọ, na ndị ọzọ. akpụkpọ ahụ na-etinye obi gị dum.
Nangwa anya akụrụngwaeserese, nnyefe ma ọ bụ reflectivity nke ihe nkiri elu na-achọkarị, na spectral nso na ọnọdụ Angle n'okpuru ngwa ngwa mkpa ka a kọwaa nke ọma. Ọ bụrụ na a chọkwara polarization, ọ dị mkpa ka akọwapụta oke nke steeti polarization. Dịka ọmụmaatụ, ihe mkpuchi chọrọ na ọnụ ọgụgụ dị n'okpuru ebe a bụ na na 770nm, ntụgharị uche kwesịrị ịbụ ihe na-erughị 88% na ogo 45, na 550nm, nnyefe kwesịrị ịbụ ihe na-erughị 70% na 45 degrees.
Na mgbakwunye na ihe ndị a na-ahụ anya dị n'elu, ọ dị mkpa ka a tụlee ihe ndị na-arụ ọrụ na kemịkalụ nke oyi akwa ihe nkiri ahụ, gụnyere nguzogide eyi, nkwụsi ike, solubility nke oyi akwa ihe nkiri. Tụkwasị na nke ahụ, ịdị mma nke elu anya mgbe mkpuchi na-achọkwa ka a tụlee, gụnyere ihe ndị a chọrọ maka pitting, scratches, unyi, stains, wdg.
