1, iyadoo la adeegsanayo tikniyoolajiyaddii ugu dambeysay ee tikniyoolajiida, si ay u muujiso hufnaanta tamarta fudud ee UV-da, waxay si dhakhso leh u qallajin kartaa injirta wasakhaysan, oo saameyn ku leh saameynta wasakhda leh {{1}
2, xulashada muraayadda aluminium saxanka, ilaha qabow ee iftiinka ee UV waxay ka tarjumaysaa boqolkiiba 90 ama ka badan, si weyn u wanaajinaya adeegsiga iftiinka ultraviolet, yareynta tamarta. Si ka duwan qaar ka mid ah soosaarayaasha yar yar ee wax laga beddelay, bir oo bir ah oo loo dejiyey macaamiisha khiyaameeya, oo aan ahayn isticmaalka nolosha gaagaaban, iyo hufnaanta milicsiga ee liita, taasoo dhalisay in khadku aysan qallajin karin sarisnimada {{2}
3, sababta oo ah khadkii kala duwan ee ku jira mawqifka UV ma aha isku mid, sidaa darteed waxay u baahan tahay in la isbarbar dhigo laambadda UV ee qaaska ah {{1} ee loo yaqaan 'The Stat laambada korantada ay tahay, nolosha dheer, iyo xasilloonida, ay ka badan tahay 3 jeer nolosha heerka caadiga ah ee {{3}
4, cabirka hooska iyo qaabka fikirka naqshadeynta, tani waa tikniyoolajiyadda nooga oo kala duwan ee iftiinka u ah nalka, si ay u muujiso isticmaalka iftiinka ee dahabka ah, oo ah in sicirka loo yaqaan 'percent loss percent percent,', oo ah in sicirka loo yaqaan 'percent percent percent percent down', oo ah heerka loo yaqaan 'is-beddelka' iyo heerka 90 si loo hubiyo in Xisaabta soo noqnoqoshada ee soo noqnoqda oo leh xasilloonida khasabka ah iyo muddada dheer, sidaa darteed runti waxaad sameyneysaa daabacaadda qalalan, oo aad u qoto dheer, gudaha in ka badan boqolkiiba 95 en . qalalan
