Izinzwa zanamuhla ziyahlukahluka ngokomthetho nangesakhiwo. Ungayikhetha kanjani izinzwa ngokufanele ngokusho kwenhloso ethile yokulinganisa, into yokulinganisa kanye nemvelo yokulinganisa yinkinga yokuqala okufanele ixazululwe lapho ulinganisa inani elithile. Lapho inzwa inqunywa, indlela yokulinganisa yokulinganisa kanye nemishini yokulinganisa nayo inganqunywa. Impumelelo noma ukwehluleka kwemiphumela yokulinganisa kuncike ngezinga elikhulu lokuthi ngabe ukukhethwa kwezinzwa kunengqondo yini.

1. Thola uhlobo lwenzwa ngokuya ngento yokulinganisa nemvelo yokulinganisa.

Ukuze sifeze isilinganiso esithile, kufanele siqale sicabangele ukuthi luhlobo luni lwezinzwa olusetshenziswayo, okudingeka lubekwe ngemuva kokuhlaziya izici eziningi. Ngoba, noma ngabe kulinganisa ubungako obufanayo ngokomzimba, kunezinhlobo eziningi zezinzwa ezizokhetha kuzo, nokuthi iyiphi efanelekile, kudingeka sicabangele izinkinga ezithile ezilandelayo ngokwezimpawu ezilinganisiwe kanye nezimo zokusetshenziswa; Izidingo zesikhundla esikalwa ngevolumu yenzwa; Ukuthi indlela yokulinganisa iyaxhumana noma ngeke Indlela yokukhishwa kwesiginali, isilinganiso esinentambo noma esingaxhumana naye; Umthombo wenzwa, efuywayo noma engenisiwe, engabizi, noma ukuze athuthukiswe.

Ngemuva kokucubungula izinkinga ezingenhla, singanquma ukuthi uluhlobo luni lwenzwa yokuzikhethela, bese ubheka inkomba ethile yokunzwa yenzwa.

2, ukukhetha kokuzwela

Ngokuvamile, ngaphakathi kobubanzi bezinsizakalo zenzwa, ukukhuphuka kokuzwela kwenzwa, okungcono. Ngoba kuphela lapho ukuzwela kuphezulu, inani lesiginali yokuphuma elihambelana noshintsho olulinganisiwe lukhulu, oluzuzisa ukucubungula ukucubungula. Kodwa-ke, kufanele kuqashelwe ukuthi ukuzwela kwenzwa kuphakeme, futhi umsindo wangaphandle ohlobene nokulinganisa kulula ukuxutshwa, futhi kuzokhuliswa futhi uhlelo lokukhuphula, oluzothinta ukunemba kokulinganisa, okuzothinta ukunemba kokulinganisa. Ngakho-ke, kuyadingeka ukuthi inzwa ngokwayo kufanele ibe nesilinganiso esiphakeme se-sinali-to-umsindo bese izama konke okusemandleni ukunciphisa amasiginali wokuphazamisa owethulwe ngaphandle.

Ukuzwela kwenzwa kuqondiswa. Lapho inani elilinganisiwe lingelona iqiniso, futhi ukuqondiswa kwalo kuyadingeka ukuba kuphakeme, izinzwa ezinozwela oluphansi kwezinye izinkomba kufanele zikhethwe; Uma i-veector elilinganisiwe ingumugqa we-muldidimensiensivelal, okuncane ukuzwela kwesiphambano senzwa kuyinto engcono.
