Ukuqonda Izinhlelo Nemvelo
Uhlelo luyinto noma iqembu lezinto ezifundwayo. Ezinye izinto endaweni yonke zibizwa ngokuthi indawo ezungezile. Ngokuvamile, uhlelo luhlukaniswa nendawo ezungezile yi-"partition/limiter/separator."
Isibonelo, ake sithi sifuna ukuphenya ngamanzi ku-thermos. Amanzi angaphakathi kwe-thermos akha uhlelo, kuyilapho umoya nezinye izinto ezingaphandle kwe-thermos zakha indawo ezungezile. Izindonga ze-thermos, kokubili ingilazi engaphakathi kanye nepulasitiki engaphandle, zisebenza njengesihlukanisi. I-thermos yamanzi iyisibonelo esisodwa.
Kunezinhlobo eziningana zezinhlelo, okungukuthi ezivulekile nezivaliwe. Uhlelo oluvulekile yilolo oluvumela ukushintshaniswa kwezinto kanye namandla phakathi kohlelo nendawo olukuyo. Izibonelo zezinhlelo ezivulekile zifaka izitshalo, izilwane, nabanye. Izitshalo ngokuvamile zimunca amanzi kanye ne-carbon dioxide endaweni ezungezile (ukushintshaniswa kwezinto). Izitshalo nazo zidinga ukushisa okuvela elangeni (ukushintshaniswa kwamandla). Abantu nabo babhekwa njengezinhlelo ezivulekile.
Uhlelo oluvaliwe luhlelo olungavumeli ukushintshaniswa kwezinto phakathi kohlelo nendawo olukuyo. Uhlelo oluvaliwe kuthiwa luhlukanisiwe uma kungekho ithuba lokushintshaniswa kwamandla phakathi kohlelo nendawo olukuyo. Uhlelo oluvaliwe kuthiwa aluhlukanisiwe uma ukushintshaniswa kwamandla phakathi kohlelo nendawo olukuyo kungenzeka. Isibonelo sesistimu evaliwe ehlukanisiwe yiflashi le-thermos elinamanzi ashisayo. Izindonga zangaphakathi zeflashi le-thermos zivame ukwenziwa ngezinto ezivikela ukushisa. Eqinisweni, izinhlelo eziningi ezihlukanisiwe azilungile kangako, futhi ukushintshaniswa kwamandla kungenzeka, yize kungenani elincane kakhulu.
