Kusetshenziswa amamitha okugeleza ahlukene ukuze kutholakale ikhwalithi yamanzi angcolile ahlukene

Ukugeleza kuyinani eliguquguqukayo, ngakho-ke ukulinganisa ukugeleza kuwubuchwepheshe obuyinkimbinkimbi, obuvela emzimbeni wokugeleza olinganisiwe, okuhlanganisa igesi, uketshezi kanye noketshezi oluxubile lwezakhiwo ezintathu ezihlukene zoketshezi; Kusukela ezimweni zokulinganisa, kodwa futhi nokuhlukahluka, embonini yensimbi njengesibonelo, ukukhiqizwa kokulinganisa uketshezi - amanzi, ngenxa yesistimu yokukhiqiza ehlukene, kuhlukaniswe ngamanzi ahlanzekile,i-turbid amanzi ajikelezayo, amanzi angcolile aguqayo ensimbi, amanzi angcolile okuncibilikisa, amanzi angcolile asekhaya kanye nezinye izinto ezahlukene.

Ukukhethwa kanye nokusetshenziswa kweimitha yokugeleza zihlukile futhi ngokwekhwalithi yendle ehlukene. Ekusetshenzisweni, indle ehlukene ekhishwayo ingasetshenziswa ezindaweni ezahlukeneamamitha okugeleza.

Amamitha okugeleza e-Ultrasonic

I-Ultrasonicimitha yokugeleza yamukela ubuchwepheshe obuthuthukisiwe be-multi-pulse, ubuchwepheshe bokucubungula idijithali yesiginali kanye nobuchwepheshe bokulungisa amaphutha, ukuze imitha yokugeleza ikwazi ukuzivumelanisa nendawo yemboni, ukulinganisa kulula kakhulu, kuyabiza futhi kunembile. Imikhiqizo ifinyelela ezingeni eliphakeme ekhaya nakwamanye amazwe, ingasetshenziswa kabanzi emasimini kaphethiloli, amakhemikhali, insimbi, amandla kagesi, ukuhlinzekwa kwamanzi kanye nokukhipha amanzi. Iphinde ilinganiswe ngesivinini sokugeleza ukuze ibonise ubukhulu bokugeleza.

Nakuba i-ultrasoundimitha yokugeleza yavela ngawo-1970, ithandwa kakhulu ngoba ingenziwa uhlobo olungathintani, futhi ingaxhunyaniswa nemitha yamanzi ye-ultrasonic ukuze ilinganise ukugeleza okuvulekile, futhi ayikhiqizi ukuphazamiseka nokumelana noketshezi.imitha yokugeleza ingahlukaniswa ngohlobo lomehluko wesikhathi kanye nohlobo lwe-Doppler ngokwesimiso sokulinganisa.

Ngaphezu kwalokho, i-ultrasound Doppler iyadingeka.imitha yokugeleza eyenziwe nge-Doppler effect isetshenziswa kakhulu ukukala i-medium ngezinhlayiya ezithile ezilengisiwe noma i-bubble medium, enemikhawulo ethile, kodwa ixazulula inkinga yokuthi umehluko wesikhathi we-ultrasonicimitha yokugeleza ingalinganisa uketshezi olulodwa olucacile kuphela, futhi ibhekwa njengethuluzi elifanele lokulinganisa okungathintaniisiqondiso esikabili ukugeleza.

I-Electromagneticimitha yokugeleza

I-Electromagneticimitha yokugeleza kuyinto entshaimitha yokugeleza yathuthuka ngokushesha ngokuthuthukiswa kobuchwepheshe be-elekthronikhi ngawo-1950 nawo-1960. I-electromagneticimitha yokugeleza uhlobo lwethuluzi elisebenzisa isimiso sokungeniswa kwe-electromagnetic futhi lilinganisa ukugeleza koketshezi oluqhubayo ngokuya ngamandla kagesi abangelwa uketshezi oluqhubayo ngokusebenzisa insimu yamagnetic yangaphandle. Linezici eziningi ezinhle kakhulu, ezingaxazulula izinkinga abanye abantu ababhekene nazo.amamitha okugeleza Akulula ukuzisebenzisa, njengokugeleza kokungcola, ukulinganisa ukugeleza kokugqwala.

Isiteshi sokulinganisa siyipayipi eliqondile elibushelelezi, elingeke livalwe. Lifanelekela ukulinganisa uketshezi oluqinile oluyi-liquid olunezigaba ezimbili oluqukethe izinhlayiya eziqinile, njenge-paper pulp, udaka, indle, njll.

Ukuqhathaniswa kwe-ultrasonic kanye ne-electromagneticamamitha okugeleza

I-Electromagneticimitha yokugeleza kanye ne-ultrasoundimitha yokugeleza, ngoba isiteshi sokugeleza kwemitha asibeki noma yisiphi isiphazamiso, azikho iziphazamisoimitha yokugeleza, ifanele ukuxazulula inkinga enzima yokulinganisa ukugeleza kwesigaba se-imitha yokugeleza, ikakhulukazi ekulinganisweni kokugeleza komlomo omkhulu kunezinzuzo ezivelele kakhulu, kungenye yentuthuko esheshayo yesigaba seimitha yokugeleza.

Okokugcina, ngendleimitha yokugeleza ukukhetha, ngakunyeimitha yokugeleza inezinzuzo nezinkinga zayo, enkambisweni yokuhlanza indle, kufanele ikhethwe ngokwezidingo zangempela. Izindleko ze-ultrasoundimitha yokugeleza iphansi, ukunemba kokulinganisa kuphakeme, ukusebenza kuzinzile, ukufakwa nokugcinwa kulula, intengo ngeke ibe phezulu kakhulu uma ububanzi bepayipi bukhuphuka, kodwa izobiza kakhulu ngenxa yokwanda komzila womsindo. I-electromagneticimitha yokugeleza inesilinganiso esizinzile, ububanzi bokusetshenziswa futhi ingalinganisa izinhlobo ezahlukene zemidiya, kodwa kulula ukuphazanyiswa amaza kagesi. Njengoba ububanzi bepayipi bukhula, intengo iba ebiza kakhulu.
