Iindaba-Ungakhetha njani idiameter yabafowunelwa bakho?

Unokukhetha njani ububanzi babafowunelwa bakho?

Ububanzi

Idayamitha yabafowunelwa bakho yiparameter kukhetho lwabafowunelwa bakho.Kukudityaniswa kombala kunye nepateni yabafowunelwa bakho kunye nobukhulu bamehlo akho kunye nabafundi.Ubukhulu be-diameter yabafowunelwa bakho, umphumo uya kucaca ngakumbi, kodwa akunjalo ukuba ubukhulu becala labafowunelwa bakho, baya kujongeka ngcono.

Khetha eyakho

"Ukunyanzeliswa kwe-oksijini yabafowunelwa kukubi xa kuthelekiswa neelensi zoqhagamshelwano eziqhelekileyo, kwaye ukuba ububanzi be-lens yoqhagamshelwano bukhulu kakhulu, kuya kuchaphazela ukuhamba kwe-lens, okwenza umphumo wokungena kwe-oksijini ube mbi ngakumbi."

Nangona unxibelelwano olukhulu lobubanzi lunempembelelo ebonakalayo, alufanelekanga kuwo wonke umntu.Abanye abantu banamehlo amancinci kunye nomfundi olinganayo, ngoko ke ukuba bakhetha uqhagamshelwano olubanzi lwe-diameter, baya kunciphisa inxalenye emhlophe yeso, okwenza iliso libukeke ngokukhawuleza kwaye lingathandeki.

Ukuthetha jikelele

Ngokubanzi, ukuba ufuna isiphumo sendalo, ungakhetha i-13.8mm yamehlo amancinci, kunye ne-14.0mm kubantu abanamehlo amakhudlwana.I-14.2mm iya kubonakala icace ngakumbi kumntu oqhelekileyo, ngoko ke unokukhetha i-13.8mm-14.0mm yomsebenzi wemihla ngemihla, isikolo, kunye nokuthandana.
