6 Inkqubo yoMlinganiso wobunzima bokugquma

6.1 Ulungelelwaniso lwezixhobo

6.1.1 Imfuzaral

Ngaphambi kokusetyenziswa, isixhobo ngasinye siya kulinganiswa ngokuhambelana nemiyalelo yomenzi, kusetyenziswa imigangatho efanelekileyo yokulinganisa. Ingqwalasela ekhethekileyo iya kuhlawulwa kwinkcazo enikwe kwiGatya lesi-3 kunye nezinto ezichazwe kwiGatya lesi-5. Ukuze kuncitshiswe utshintsho lwe-conductivity ngenxa yokutshintsha kwamaqondo obushushu, ngexesha lokulinganisa isixhobo kunye nemigangatho yokulinganisa iya kuba kwiqondo lokushisa elikufutshane ubushushu bezinto eziza kulinganiswa.
QAPHELA Ukuhlolwa kolungelelwaniso kufuneka kwakhona kwenziwe njengoko kuyimfuneko ngexesha lokumisela ukuthintela ukukhukuliseka kwesixhobo.

6.1.2 Imigangatho yolungelelwaniso

Ulungelelwaniso lwesixhobo luya kwenziwa kusetyenziswa ubuncinci imigangatho emibini yobunzima obahlukeneyo nolwaziwayo. Enye yale migangatho inokuba yeyomathiriyeli wesiseko esingafakwanga.
QAPHELA 1 Imigangatho elolo hlobo kufuneka ukuba ubukhulu bayo bulandelelwe kumthombo oqinisekisiweyo.
I-conductivity yombane kunye nemagnethi yokungena kuzo zombini i-coating kunye nesiseko semathiriyeli iya kufana nezo mpawu zeendawo eziza kulinganiswa.
QAPHELA 2 Njengoko imigangatho yolungelelaniso ixhomekeke ekugugileni kunye nokuhla ngokuhamba kwexesha kunye nokusetyenziswa, kufuneka ihlaziywe ngokutsha kunye/okanye itshintshwe ngamaxesha athile ngamaxesha amisiweyo ekuhlaleni okanye emva kokubonisana nomvelisi.

6.1.3 Ukungqinisisa

Iimpawu zombane zezinto ezisisiseko zemigangatho yokulinganisa ziya kufana nezo zesiseko semathiriyeli yovavanyo.
QAPHELA Ukuqinisekisa ukufaneleka kwazo, ufundo olufunyenwe ngesiseko semathiriyeli yomgangatho wolungelelwaniso olungafakwanga kunye naloo mzekelo wovavanyo kufuneka luthelekiswe.
Ukuba ubukhulu bezinto ezisisiseko budlula ubukhulu obubalulekileyo, njengoko kuchazwe kwi-5.3, umlinganiselo wobunzima awuchaphazeli ubuninzi bezinto ezisisiseko.
Ukuba ubunzima obubalulekileyo abugqithiswanga, ubukhulu bezinto ezisisiseko zovavanyo kunye nokulinganisa kuya kufana. Ukuba, phantsi kweemeko eziphathekayo, oku akunakwenzeka ngoko kunokwenzeka ukubuyisela umva umgangatho okanye isampuli yovavanyo kunye nobukhulu obaneleyo bemathiriyeli eneempawu zombane ezifanayo ukwenza ufundo luzimele kubukhulu bezinto ezisisiseko. Ukuba le ndlela isetyenzisiwe, uvavanyo luya kwenziwa ukuqinisekisa ukuba lwamkelekile kwaye lusekwe ubukho bazo naziphi na iimpazamo ezongezelelweyo.Ukuba ukugoba komgangatho ogqunyiweyo kuya kulinganiswa kufana nokuthintela ulungelelwaniso kumphezulu osicaba, imigangatho esetyenziswayo. kuba ulungelelwaniso luya kuba neradiyi efanayo yokugoba njengomzekelo oza kulinganiswa, ngaphandle kokuba uphononongo olukhethekileyo olubuyekeza impembelelo yegophe lusetyenziswa.

6.2 Ukuzimisela

6.2.1 Imfuzaral

Sebenzisa isixhobo ngasinye ngokungqinelana nemiyalelo yomenzi, unike ingqwalasela efanelekileyo kwizinto ezinikwe kwiGatya lesi-5.
Jonga ukulinganisa kwesixhobo, usebenzisa imigangatho yokulinganisa esebenzayo, kwindawo yovavanyo rhoqo xa isixhobo sifakwa kwinkonzo kwaye ngamaxesha aqhelekileyo ngexesha lokusetyenziswa (ubuncinane kanye ngeyure) ukuqinisekisa ukusebenza kakuhle (jonga i-6.1).
Amanyathelo okhuseleko adweliswe ku-6.2.2 ukuya ku-6.2.6 aya kuqwalaselwa.

6.2.2 Ukucoceka komphezulu

Phambi kokwenza imilinganiselo, susa nawuphi na umbandela wangaphandle onje ngokungcola, ioyile, igrisi kunye neemveliso ezidlekayo kumphezulu wemigangatho kunye nomzekelo wovavanyo, ngaphandle kokususa naziphi na izinto zokugquma.

6.2.3 Isiseko sobukhulu bentsimbi

Khangela ukuba izinto ezisisiseko zidlula ubukhulu obubalulekileyo (jonga i-5.3). Ukuba akunjalo, sebenzisa indlela yogcino oluchazwe ku-6.1.3 okanye uqinisekise ukuba ulungelelwaniso lwenziwe kumgangatho wokulinganisa onobunzima obufanayo kunye neempawu zombane njengomzekelo wovavanyo.

6.2.4 Iziphumo zomda

Musa ukwenza imilinganiselo kufutshane nongqameko, umngxuma, ikona engaphakathi, njl.njl., yomzekelo wovavanyo ngaphandle kokuba kubonakalisiwe ukulunga kolungelelwaniso lwaloo milinganiselo (jonga isiHlomelo B).

6.2.5 Igophe

Musa ukwenza imilinganiselo kumphezulu ogobileyo womzekelo wovavanyo, ngaphandle kokuba ukulunga kolungelelwaniso lwemilinganiselo enjalo kubonisiwe.

6.2.6 Inani lezinto ezifundiweyo

Inani lemilinganiselo eyenziwe kwindawo efanayo, ukuba kuyimfuneko ukusebenzisa i-jig ye-probe, iya kunika ulwazi malunga nokuphindaphinda (ukuphambuka okuqhelekileyo) kwesixhobo kunye ne-probe yayo ngelo xesha kunye nobukhulu obulinganiswayo.

PHAWULA:

I-coefficient of variation, V, ingabalwa kulo mgangatho wokutenxa. U-V unokufakwa kuluhlu lweengqimba.
Inani lemilinganiselo eyenziwa ngokuhambisa i-probe phakathi komlinganiselo ngamnye, kwaye ngaphakathi kwendawo echaziweyo kwindawo edibeneyo, iya kunika ulwazi malunga nokuphindaphinda kwesixhobo kunye nokugubungela ngaphakathi kwendawo echaziweyo.

Ukuba umphezulu wokugquma urhabaxa okanye iisampulu zovavanyo zaziwa zineemitha zobukhulu obukhulu kumphezulu wazo (umzekelo, ngenxa yobukhulu kunye/okanye imilo) imvelaphi yeeyantlukwano zomlinganiselo kufuneka zisekwe ngemilinganiselo emininzi.
