Uyini umehluko phakathi kwesikhwama esiyisicaba kanye nesikhwama sokumisa?

Izinhlobo ezimbili zezikhwama zeasukume isikhwama futhiisikhwama esiphansi esiphansi okwamanje asetshenziswa kabanzi ekupakishweni, futhi abanjwe lapho uhlobo lwesikhwama olufaneleka kakhulu umkhiqizo lapho kwenziwa ngokwezifiso isikhwama. Umphumela we-three-dimensional wesikhwama esizimele kanye nesikhwama sokuvala uphawu esinezinhlangothi eziyisishiyagalombili ungcono, umehluko ukuthiisikhwama esiphansi esiphansi inqubo iyinkimbinkimbi futhi ukubukeka kuyinto enhle. Namuhla, sizokunikeza isifinyezo sezinzuzo kanye nokwehluka kwe-isikhwama esiphansi esiphansi futhiasukume isikhwama.

Esokuqala yi-isikhwama esiphansi esiphansi: Iphansi lalesi sikhwama liklanywe ngokushelela kakhulu, futhi kukhona ingqikithi yezinhlangothi eziyisishiyagalombili, ngakho yaziwa nangokuthi isikhwama esizisekelayo esinezinhlangothi eziyisishiyagalombili. Inemiphetho emi-4 phansi, nemiphetho emi-2 ohlangothini ngalunye, ngakho-ke kukhona imiphetho eyi-8 isiyonke.Isikhwama esiphansi esiphansi inezindawo zokubonisa ezinhlanu, ngokulandelana, ngaphambili, ngemuva, kwesokunxele, kwesokudla ezine ubuso, phansi futhi inobuso. Ngakho, iisikhwama esiphansi esiphansi ingaphatha ulwazi olwengeziwe lwemidiya kanye nokubonisa kangcono nokuphromotha ukudla nemikhiqizo.

Okwesibili,asukume isikhwama: okungezansi kungagoqeka emuva futhi kunemiphetho emibili yokuvala, phansi kungenziwa ukwelulelwa futhi kuzimele, lesi sikhwama siyisikhwamaasukume isikhwama. Iphansi lesikhwama lenzelwe ukugoqa emuva, futhi lifakwe emaphethelweni amabili okuvalwa, futhi kukhona umkhawulo wokuvala ohlangothini ngalunye, lapho kuvulwa phansi, isikhwama singasebenza ngokuzimela. Kunomehluko emibili phakathi kwe-isikhwama esiphansi esiphansi kanye a asukume isikhwama, ngokuphelele. Okokuqala, ekupheleni engezansiasukume isikhwama ayisicaba, futhi ingxenye engezansi yophawu olunezinhlangothi eziyisishiyagalombili iyisicaba; Okwesibili ukuthi inani eliphelele lokugoqa kwabo lihlukile, inani leasukume isikhwama ibe 4,isikhwama esiphansi esiphansi ngu-8, futhi inani eliphelele lezindawo zokubonisa lihlukile, i-sphakamisa isikhwama kungaba 2 kuphela, futhi isikhwama esiphansi esiphansi onqenqemeni 5. Sekukonke, ezimeleisikhwama esiphansi esiphansi ingcono, inezigaba eziningi futhi izinzile kune-asukume isikhwama; Nokho, intengo yeisikhwama esiphansi esiphansi ibiza kakhulu.

Isikhwama esiphansi esiphansi inezinzuzo ezifanayo njenge-aasukume isikhwama. Okokuqala, bonke banamandla okuma. Babekwazi ukugcina ukuma okuzinzile kungakhathaliseki ukuthi bagcwele noma yini. Kungakhathaliseki ukuthi iyathengiswa noma iyasetshenziswa, isinika izinto eziningi ezilula. Okwesibili, inomqondo othambile onezinhlangothi ezintathu. Imikhiqizo yokupakisha abayihlinzekayo isezingeni eliphezulu futhi iyaphana, idonsa amehlo kakhulu, futhi ingashiya izinkumbulo ezingenakulibaleka kubantu, okudlala indima ebalulekile ekuthuthukiseni umkhiqizo. Okwesithathu, isitayela sesikhwama. Ngemva kokugcwalisa into, iisikhwama esiphansi esiphansi kanye neasukume isikhwama ingagcina i-flatness engcono nokubukeka okuhle, okungenakwenzeka ngezinye izikhwama. Okwesine, ingafakwa i-zipper engasetshenziswa kabusha, ikhasimende lingavula noma livale uziphu futhi, ibhokisi alikwazi ukufaniswa.
