Izinyathelo zokulawula iphutha lokulinganisa
Empeleni, isizathu esenza iphutha lesilinganiso sesikali, ngaphezu komthelela wekhwalithi yalo, nokusebenza kwabasebenzi, izinga lobuchwepheshe, njll. kube nokuhlobana okuqondile.Okokuqala, ikhwalithi ephelele yabasebenzi abahlolayo ithinta ukunemba kokuhlolwa kwesikali, ekusebenzeni kokuhlola uma abasebenzi bengasebenzi ngokuhambisana nezinqubo ezijwayelekile zokuhlola i-metrological, kulula ukuholela ekulinganisweni kwesikali. ukuhlola iphutha.Isibonelo, lapho uhlola ukusebenza kwe-push kanye nebhalansi kwezikali, kulula kakhulu ukuthi abahloli banganaki ukuhlolwa kokuhlukahluka kwezikali ezingenalutho.Okwesibili, izikali zisetshenziselwa ukulinganisa isisindo sezinto, futhi ngokusekelwe ezingeni lokusebenza, zingahlukaniswa zibe izilawuli zikagesi, amaseli omthwalo, izilawuli zokubonisa isisindo, njll Ngokuthuthukiswa kwesayensi yezenhlalakahle nobuchwepheshe, izikali zisetshenziswa kakhulu. lokukala isisindo sezinto.Ngokuthuthuka kwesayensi yezenhlalo nobuchwepheshe, uhlelo lokusebenza kwesikali lwenze izinguquko ezinkulu, futhi seluthuthukisiwe kusukela esilinganisweni esivamile ukuya ku-modularization kanye nobuhlakani, kodwa ngenxa yokuthi ubuchwepheshe bokulawula budinga ukuthuthukiswa, kusenokuphambuka okukhulu esilinganisweni sokulinganisa. , ububanzi obujwayelekile, njalonjalo.
Ukulinganisa izikali zikagesi, ngokuvamile ezisetshenziswa ezimakethe zohwebo nakweminye imikhakha, okuhlanganisa amaphuzu okukala ayisithupha afana no-5 g, 10 g, 20 g, ahambisana nephutha elivumelekile lika-± 0.1 g, ± 0.5 g, njll., lapho benza ukukalwa kanye nokulinganiswa kwezikali zikagesi, izisebenzi zokulinganisa kufanele zinamathisele ukubaluleka okukhulu endaweni yokukala kanye nenani lephutha elivumelekile, namarekhodi anemininingwane yedatha yesisindo esijwayelekile phakathi nenkathi yokukala, engalinganiswa ngephutha lokulinganisa izikali ze-elekthronikhi zingalawulwa ngaphakathi kwemingcele enengqondo.Lokhu kungalawula iphutha lokulinganisa lezikali ze-elekthronikhi ngaphakathi kwebanga elinengqondo.Ngesikhathi esifanayo, isikhulu esiqinisekisayo kufanele futhi sigcwalise "Isitifiketi Sesitifiketi" ngokunengqondo ngesimo sesilinganiso se-elekthronikhi, futhi sihambise isitifiketi kumnyango onekhono ukuze sihlolwe, okungase futhi kuthuthukise umphumela wokulinganisa wesilinganiso se-elekthronikhi.Khonamanjalo, ohlelweni lokuphindaphinda ukulinganisa, ukuze kuthuthukiswe ukunemba kwemiphumela yokulinganisa, abasebenzi bokulinganisa badinga ukubeka amathuluzi okulinganisa isikali se-elekthronikhi ezimeni ezahlukene zokulinganisa, bese benza umsebenzi omuhle wokurekhoda idatha yokulinganisa, okuyinto futhi ingathuthukisa ukunemba kwemiphumela yokulinganisa.
Ukukalwa kwendlela yentuthuko yesikhathi esizayo yemboni yokukala
Izilinganiso zokulinganisa zizoguqulwa zisuka esikalini se-analog electronic zibe izikali zikagesi zedijithali, kanye nokuthuthukiswa kobuchwepheshe be-microelectronics, inqubo yokukhiqiza izinzwa zedijithali iya ngokuya iphelele, izikali ze-analog electronic zizothathelwa indawo ngempumelelo izikali ze-digital electronic, izikali ze-digital electronic ngenxa ukwethembeka kwemiphumela eqinile, emihle yokulinganisa, ngakho izobonwa yimakethe.Izikali ezingezona ezizenzakalelayo nazo zizoqhubeka nokuthuthuka ziye esikalini esizenzakalelayo, futhi isikali sendabuko, esisodwa sizothathelwa indawo yimishini ezishintshayo, izinhlelo zokukala.Ngokuthuthuka kwemboni yesikali sokulinganisa, ukusetshenziswa kweShayina kwezikali zokulinganisa akusewona umsebenzi owodwa, futhi kuhlanganiswe nokuphatha, ukulawula nokuqapha, njll., amabhizinisi akhiqizayo azokwenza futhi ukwakhiwa kwemishini yokudlulisa nokugcina.Ngokuqondene nobuchwepheshe bokukala buzoshintsha kusuka esikalini esivamile esimile siye esikalini esiguquguqukayo.Isilinganiso sisuka esilinganisweni se-analogi siye esilinganisweni sedijithali, ukukalwa kwepharamitha eyodwa kuzoba ukukalwa kwepharamitha eningi, futhi ukusebenza kobuchwepheshe kwesikalo nakho kuzoqondana nesiqondisindlela sokuzinza okuqinile, ukunemba okuphezulu nezinga elihle lokuthuthuka.Ngaphezu kwalokho, izikali zokulinganisa zizothambekela ekwenzeni i-miniaturization, i-modularity, ukuhlanganiswa kanye nokuqondisa okuhlakaniphile.Ngokusetshenziswa kwezikali zokulinganisa, ukuthuthukiswa, imishini yesisindo izoqhubeka nokunciphisa ubukhulu, ukuphakama kuzoncishiswa, kodwa futhi kubonise inhlanganisela ehlukene yomkhuba we-modular.Ngaphansi kwalo mkhuba, ukwethembeka kanye nokuguquguquka kwemikhiqizo kuzothuthukiswa kakhulu, futhi izinga lokukhiqiza kanye nomthelela wemikhiqizo yesikali kuzoqiniswa.
