Oomatshini bokupakisha banokwahlulwa babe ngokuthe nkqo kunye nabathe tye, kwaye abo bathe nkqo bangohlulwa zibe ziqhubekayo (ezikwabizwa ngokuba luhlobo lwe-roller) kunye ne-intermittent (eyaziwa ngokuba luhlobo lwesundu).Bagginginokwahlulwa ibe kukutywinwa kwamacala amathathu, ukutywinwa kwamacala amane, ukutywinwa ngasemva, kunye nenani lemigca yezixhobo zokupakisha.Kukho iintlobo ezininzi zezixhobo zokupakisha, kwaye umahluko phakathi kwazo mkhulu.Ekusetyenzisweni kwangempela kwezinto ezidibeneyo ze-membrane ezidibeneyo, siya kuhlangabezana neengxaki ezahlukeneyo.Eli phepha lihlalutya oonobangela beengxaki ezintandathu eziqhelekileyo ngokweenkcukacha ngereferensi.
1, Iingxaki zekhesa
Kwinkqubo yokupakishwa okuzenzekelayo kweiikhoyili zefilimu ezidibeneyo, ukubeka ukutywinwa kokushisa kunye nokumisa ukusika kudla ngokufuneka, kwaye i-cursor yamehlo yombane iyadingeka ekumiseni.Ubungakanani bekhesa buhluka ngamathuba ahlukeneyo okupakisha.Ngokuqhelekileyo, ububanzi bekhesa bungaphezulu kwe-2mm kwaye ubude bungaphezulu kwe-5mm.Ngokubanzi, ikhesa ngumbala omnyama onomahluko omkhulu kunye nombala ongasemva.Kungcono ukusebenzisa umnyama.Ngokuqhelekileyo, ibomvu kunye nephuzi ayinakusetyenziswa njengekhesa, kwaye ikhowudi yombala enombala ofanayo kunye neso lesithombe sombane inokusetyenziswa njengombala wekhesa.Ukuba umbala oluhlaza okhanyayo usetyenziswa njengombala wekhesa weso lefotoelectric, kuba iliso lefotoelectric eliluhlaza alikwazi ukuqaphela umbala oluhlaza.Ukuba umbala ongasemva ngumbala omnyama (ofana nomnyama, oluhlaza okwesibhakabhaka, omfusa obumnyama, njl.njl.), uphawu lwexesha kufuneka lwenziwe njengekhesa yombala wokukhanya ongenanto kunye nomhlophe.
Inkqubo yamehlo yombane yomatshini oqhelekileyo wokupakisha ngokuzenzekelayo yinkqubo yokuchonga elula, engenako ukwenza umsebenzi wokulungisa ubude obukrelekrele njengomatshini wokwenza ingxowa.Ngoko ke, ngaphakathi koluhlu olude lwekhesa yamehlo ombane, iifilimu eqengqelekayoayivumelekanga ukuba ibe namagama aphazamisayo kunye neepateni, kungenjalo iya kubangela iimpazamo zokuchongwa.Ngokuqinisekileyo, ibhalansi emnyama kunye emhlophe yamehlo athile ombane anovakalelo oluphezulu inokulungelelaniswa ngokuchanekileyo, kwaye ezinye iimpawu zokuphazamiseka ezinombala okhanyayo zingasuswa ngokuhlengahlengiswa, kodwa iimpawu zokuphazamiseka kwepatheni ezinemibala efana okanye emnyama kunekhesa ayikwazi ukususwa.
