Kuvavanywa njani ukuchaneka komphezulu weqonga lokuhlola imabula kwilebhu?

Kwiilabhoratri ezichanekileyo, amaqonga okuhlola imabula—akwaziwa ngokuba ziipleyiti zomphezulu wemabula—adlala indima ebalulekileyo njengeziseko zokulinganisa, ukulinganisa, kunye nemisebenzi yokuhlola. Ukuchaneka kwala maqonga kuchaphazela ngokuthe ngqo ukuthembeka kweziphumo zovavanyo, yiyo loo nto uvavanyo lokuchaneka komphezulu luyinxalenye ebalulekileyo yolawulo lomgangatho.

Ngokwemigangatho yokuqinisekisa i-metrological JJG117-2013, amaqonga okuhlola imabula ahlulwe ngokwamanqanaba amane okuchaneka: iBanga 0, iBanga 1, iBanga 2, kunye neBanga 3. La manqanaba achaza ukuphambuka okuvumelekileyo ekuthambekeni nasekuchanekeni komphezulu. Nangona kunjalo, ukugcina le migangatho ngokuhamba kwexesha kufuna ukuhlolwa rhoqo kunye nokulinganiswa, ngakumbi kwiindawo apho ukuguquguquka kobushushu, ukungcangcazela, kunye nokusetyenziswa kakhulu kunokuchaphazela imeko yomphezulu.

Ukuvavanya ukuchaneka komphezulu

Xa kuvavanywa ukuchaneka komphezulu weqonga lokuhlola imabula, kusetyenziswa isampuli yokuthelekisa njengereferensi. Le sampuli yokuthelekisa, edla ngokwenziwa ngezinto ezifanayo, inika ireferensi ebonakalayo nenokulinganiseka. Ngexesha lovavanyo, umphezulu ophathweyo weqonga uthelekiswa nombala kunye nobume besampuli yokubhekisa. Ukuba umphezulu ophathweyo weqonga awubonisi ipateni okanye ukuphambuka kombala ngaphaya kwesampuli yokuthelekisa eqhelekileyo, kubonisa ukuba ukuchaneka komphezulu weqonga kuhlala kukwinqanaba elamkelekileyo.

Uvavanyo olupheleleyo, iindawo ezintathu ezahlukeneyo eqongeni zihlala zikhethwa ukuze kuvavanywe. Inqaku ngalinye lilinganiswa kathathu, kwaye ixabiso eliqhelekileyo lale milinganiselo limisela iziphumo zokugqibela. Le ndlela iqinisekisa ukuthembeka kwezibalo kwaye inciphisa iimpazamo ezingacwangciswanga ngexesha lokuhlolwa.

Ukungaguquguquki kweeMpawu zoVavanyo

Ukuqinisekisa iziphumo ezichanekileyo neziphindaphindwayo, iisampuli zovavanyo ezisetyenziswa kuvavanyo lokuchaneka komphezulu kufuneka zicutshungulwe phantsi kweemeko ezifanayo nezo zeqonga elivavanywayo. Oku kuquka ukusebenzisa izinto ezifanayo zokwenza imveliso kunye neendlela zokugqiba, kunye nokugcina iimpawu zombala kunye nobume obufanayo. Ukuhambelana okunjalo kuqinisekisa ukuba uthelekiso phakathi kwesampuli kunye neqonga luhlala luchanekile kwaye lunentsingiselo.

Ukugcina Ukuchaneka Kwexesha Elide

Nokuba kunokwenziwa ngokuchanekileyo, iimeko zokusingqongileyo kunye nokusetyenziswa rhoqo kunokuchaphazela kancinci kancinci umphezulu weqonga lokuhlola imabula. Ukuze kugcinwe ukuchaneka, iilabhoratri kufuneka:

• Gcina iqonga licocekile kwaye lingenalo uthuli, ioyile, kunye nentsalela yesipholisi.

• Kuphephe ukubeka izinto ezinzima okanye ezibukhali ngqo kumphezulu wokulinganisa.

• Qinisekisa rhoqo ukuba umphezulu uthe tyaba kwaye uchanekile usebenzisa izixhobo eziqinisekisiweyo okanye iisampulu zesalathiso.

• Gcina iqonga kwindawo ezinzileyo enomswakama olawulwayo kunye nobushushu.

Isiphelo

Ukuchaneka komphezulu weqonga lokuhlola imabula kubalulekile ekugcineni ukuchaneka kokulinganisa nokuhlola elebhu. Ngokulandela iindlela zokulinganisa ezisemgangathweni, ukusebenzisa iisampulu zokuthelekisa ezifanelekileyo, kunye nokunamathela kwiindlela zokugcina ezihambelanayo, iilabhoratri zinokuqinisekisa uzinzo lwexesha elide kunye nokuthembeka kweepleyiti zazo zomphezulu wemabula. Kwi-ZHHIMG, senza kwaye silinganise amaqonga okuhlola imabula kunye negranite ngokwemigangatho yamazwe ngamazwe, sinceda abathengi bethu ukuba bagcine ukuchaneka kokulinganisa okungagungqiyo kuyo yonke isicelo.
