Iindaba-Ungakhetha njani ubukhulu babafowunelwa 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 kubonakala 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 ukudibanisa ubukhulu obukhulu, baya kunciphisa indawo 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.
