Uyini umehluko phakathi kwesikhwama esisicaba nesikhwama sokuma?

Izinhlobo ezimbili zezikhwamaisikhwama sokuma futhiisikhwama esiphansi esiyisicaba okwamanje zisetshenziswa kabanzi ekupakisheni, futhi ziboshwe ngohlobo lwesikhwama olufaneleka kakhulu kumkhiqizo lapho kwenziwa ngokwezifiso isikhwama. Umphumela wesikhwama esizimele kanye nesikhwama sokuvala esinamahlangothi ayisishiyagalombili ungcono, umehluko uwukuthiisikhwama esiphansi esiyisicaba inqubo iyinkimbinkimbi kakhulu futhi ukubukeka kwayo kuyamangalisa. Namuhla, sizokunikeza isifinyezo sezinzuzo nomehluko weisikhwama esiphansi esiyisicaba futhiisikhwama sokuma.

Okokuqala yi-isikhwama esiphansi esiyisicaba: Ingxenye engezansi yalesi sikhwama yakhiwe kahle kakhulu, futhi kunezinhlangothi eziyisishiyagalombili sezizonke, ngakho-ke yaziwa nangokuthi isikhwama esizisekelayo esivalayo esinezinhlangothi eziyisishiyagalombili. Sinezinhlangothi ezine phansi, kanye nezinhlangothi ezimbili ohlangothini ngalunye, ngakho-ke kunezinhlangothi eziyisishiyagalombili sezizonke.Isikhwama esiphansi esiyisicaba inezindawo zokubonisa ezinhlanu, ngokulandelana, ngaphambili, emuva, kwesobunxele, kwesokudla ubuso obune, phansi futhi kunobuso. Ngakho-ke,isikhwama esiphansi esiyisicaba ingathwala ulwazi olwengeziwe lwabezindaba kanye nokuboniswa okungcono nokukhuthazwa kokudla kanye nemikhiqizo.

Okwesibili,isikhwama sokuma: iphansi lingagoqwa libuyele emuva futhi linemiphetho emibili yokuvala, iphansi lingalulwa futhi lizimele, lesi sikhwama singu-isikhwama sokuma. Ingaphansi lesikhwama lenzelwe ukugoqa emuva, futhi lifakwe imiphetho emibili yokuvala, futhi kukhona umphetho wokuvala ohlangothini ngalunye, lapho iphansi livuliwe, isikhwama singasebenza ngokuzimela. Kunezinhlobo ezimbili zomehluko phakathi kweisikhwama esiphansi esiyisicaba kanye isikhwama sokuma, iyonke. Okokuqala, ingxenye engezansi yeisikhwama sokuma akusicaba, kanti ingxenye engezansi yesivalo esinezinhlangothi eziyisishiyagalombili isicaba; Okwesibili ukuthi inani eliphelele lokugoqa kwabo lihlukile, inaniisikhwama sokuma ingu-4, iisikhwama esiphansi esiyisicaba ingu-8, futhi inani eliphelele lezindawo zokubonisa lihlukile, i-sisikhwama sokubopha kungaba yi-2 kuphela, futhi isikhwama esiphansi esiyisicaba umkhawulo u-5. Sekukonke, ozimeleisikhwama esiphansi esiyisicaba kungcono, kungokwesigaba futhi kuzinzile kakhulu kune-isikhwama sokumaKodwa-ke, intengo yeisikhwama esiphansi esiyisicaba kuyabiza kakhulu.

Isikhwama esiphansi esiyisicaba inezinzuzo ezifanayo njenge-isikhwama sokuma. Okokuqala, bonke banekhono lokuma. Bakwazile ukugcina ukuma okuzinzile kungakhathaliseki ukuthi bagcwele noma yini. Kungakhathaliseki ukuthi kuyathengiswa noma kuyasetshenziswa, kusinika lula kakhulu. Okwesibili, kunomuzwa obucayi wezinhlangothi ezintathu. Imikhiqizo yokupakisha abayinikezayo isezingeni eliphezulu futhi iyaphana, iheha kakhulu amehlo, futhi ingashiya izinkumbulo ezingasoze zalibaleka kubantu, okudlala indima ebalulekile ekukhangiseni uphawu. Okwesithathu, isitayela sesikhwama. Ngemva kokugcwalisa into,isikhwama esiphansi esiyisicaba kanyeisikhwama sokuma ingagcina isicaba esingcono kanye nokubukeka okuhle, okungenakwenzeka ngezinye izikhwama. Okwesine, ingafakwa uziphu ongasetshenziswa kabusha, ikhasimende lingavula noma livale uziphu futhi, ibhokisi alikwazi ukufana.
