Inhlanganisela ngokusho komkhiqizi wentuthuko yemboni yemishini yokulinganisa yesimanje

Imboni yemishini yokukala yezwe lethu inomlando omude wezimboni zendabuko kanye nemboni ebalulekile eyisisekelo. Eminyakeni edlule, imishini yokukala yemishini inikezwa kuqala. Ngawo-1980 kwaqala ukwandisa ukusetshenziswa kwemishini yokukala ye-elekthronikhi kanye nokuthuthukiswa kwemishini emikhulu yokukala ezenzakalelayo, kodwa izinga layo lokuhlakanipha uma liqhathaniswa nemikhiqizo efanayo yakwamanye amazwe, inegebe elithile. Imikhiqizo yokuqukethwe kobuchwepheshe obuphansi iyizithiyo zokungena emakethe yamazwe ngamazwe eShayina, ubunzima bokuthola izintshisekelo zamazwe ngamazwe. Ekuhlanganisweni komnotho wezwe lanamuhla, iShayina ayisakwazi 'ukuvikela imboni yasekhaya' kuphela ngokudluliselwa kobuchwepheshe bamazwe ngamazwe, ukushintshana kobuchwepheshe bamazwe ngamazwe phakathi kwemali yamazwe ngamazwe ukugeleza kokuhamba ukuhlomisa imishini yokukala ibhizinisi ezweni lethu, emakethe yamazwe ngamazwe kuya kumkhiqizo kuze kube sesimanje. Ngokuthuthuka kwesimanje, kodwa futhi ngesakhiwo sesidingo sezenhlalo ukuthambekela kokudla isakhiwo sokusetshenziswa kanye nentuthuko yezobuchwepheshe kanye nokuhweba kwamazwe ngamazwe.

Kusukela emnothweni ohleliwe kuya emnothweni wemakethe ezweni lethu nakho kuletha isidingo senhlalo kanye noshintsho lokuthambekela kokusetshenziswa. Kusukela ngawo-1990, isibonelo, ukuthengiswa emkhakheni wokujikeleza komnotho ezweni lethu kushintshile, ngobuningi ngaphandle kokupakisha ifomu lokuthengisa liye lathathelwa indawo kancane kancane 'ukupakisha' kwalo, 'ukupakisha' kwalo kanye nokuhlukahluka kwesikhathi okuhlelekile kanye nokupakisha okuhle kuthole ukuthandwa ngabathengi abaningi, kanye nokwanda kwesidingo semakethe kanye noshintsho lokuthambekela kokusetshenziswa, isisindo somshini wokuhlola njengokwenziwa kwesimanje kwezinsimbi zokulinganisa eziku-inthanethi njengendlela yokulinganisa ukupakisha, ukunakwa okwengeziwe ngabantu bebhizinisi kanye nomnyango we-metrology.

Le divayisi yokulinganisa ngokuzenzakalelayo enokuqukethwe kwayo kobuchwepheshe obuphezulu kanye nemisebenzi eyingqayizivele yokulawula impendulo ezenzakalelayo, amakhemikhali amahle ekudleni, isikhungo sokusabalalisa izinto zemithi kanye nezinye izimboni ezisetshenziswa kabanzi. Ngawo-1970, inhlangano yezolimo yaseJapan ezinkampanini zezinsimbi ezifanele yabeka phambili isisindo sikapelepele oluhlaza. EJapane, upelepele oluhlaza ngokuvamile ngesimo sezikhwama zokupakisha ezinobuningi ezitolo ezinkulu, uma isikhwama ngasinye sinobuningi obungamagremu angu-120, upelepele oluhlaza ukuze ufike ku-120 g kuyinto enzima kakhulu ukuyenza. Ngoba isisindo sikapelepele oluhlaza esisodwa sinzima kakhulu, futhi umehluko mkhulu, awuhlobene kakhulu nentshisekelo yabathengi, uhlobene kakhulu nezindleko zebhizinisi. Indlela yendabuko iwukuba nesisindo sokwenziwa, okungukuthi, uma kushiwo esilinganisweni se-elekthronikhi esingaguquki, upelepele oluhlaza ngomuntu ngamunye uqongelela kumagremu angu-115, ufuna ukuthola upelepele oluhlaza ongu-5 g ukwengeza kuwo cishe akunakwenzeka, kumele kube kusuka ku-115 g kuya kupelepele oluhlaza omncane, kanye nomunye omkhulu upelepele oluhlaza. Kakhulu uma isisindo singaphezu kwamagremu angu-120 noma ngaphansi kwamagremu angu-120, futhi sidinga ukuphinda umsebenzi ongenhla, ukusebenza kahle kokukala kuphansi kakhulu, futhi kunzima ukufeza eduze kwesisindo esiqondiwe (Amanani Okulinganisa) Imiphumela. Ngemva kokuba abasebenzi bezobuchwepheshe babe nenani elikhulu locwaningo nokutadisha, besebenzisa isimiso sokulinganisa esihlanganisiwe baxazulula ngempumelelo inkinga yopelepele oluhlaza. Amanye amabhizinisi amakhulu okudla njengemishini eqokiwe. Ukukhiqizwa kwezimboni kwanamuhla nokuphila kwansuku zonke akuhlukaniseki ekulinganisweni, futhi ngokuthuthukiswa kokukhiqizwa, ukunemba kokukala kuyathuthuka, ikakhulukazi ekupakishweni kokudla, amakhemikhali, ezemithi kanye nezinye izimboni, kudingeka kube nokunemba okuphezulu kokukala. Ngesakhiwo somshini ukuze kufezwe idivayisi enesisindo esinembile kakhulu, hhayi isakhiwo esiyinkimbinkimbi kuphela, kanye nokusekelwa (I-blade nommese) Ibuthakathaka futhi kulula ukuyigqoka kanye nokugqwala, iqinile endaweni yokusebenza, umthwalo wokulungisa mkhulu, ubuthakathaka obukhulu buyisivinini sokukala kancane, ukusebenza kahle okuphansi, futhi ayikwazi ukuzivumelanisa nezidingo zokuthuthukiswa kokukhiqizwa. Ukuze kunqotshwe ukushiyeka okungenhla, ekhulwini lokugcina lama-60, abantu bathuthukise uhlobo lwesilinganiso se-elekthronikhi esihlanganisiwe se-elekthronikhi, sakhiwe uhlelo lwe-lever, idivayisi ye-grating kanye nesekethe yezingxenye ezintathu. Uhlelo lwe-lever ngaphansi kwesenzo somthwalo, ukufuduka, idivayisi yokugaya iguqula ukufuduka kube yisekethe kagesi, isignali yedijithali ngemuva kokuhlanganiswa ngokusho komkhiqizi nethuluzi ledijithali kubonisa inani lesisindo. Inhlanganisela ngokusho komkhiqizi lesi sikali kunesikali se-lever esinomshini esithuthukisiwe ngokunemba, ukusetshenziswa okulula kakhudlwana, amanani esisindo atholakalayo ukubonisa okubonakalayo kwedijithali, kanye nesignali yesisindo ingadluliselwa ebangeni elide.
