Qaphela Ukwaziswa Okufakayo

ukufaka idatha eyodwa kabili.

fx-82MS/fx-85MS/fx-300MS/fx-350MS: Ungaphinda ufake ukwaziswa okufanayo kaningana usebenzisa (;). Ukufaka idatha engu-110 izikhathi eziyishumi, ngokwesibonelo, cindezela u-110(;) 10.
fx-220 PLUS: Ungaphinda ufake ukwaziswa okufanayo kaningana usebenzisa (;). Ukufaka idatha engu-110 izikhathi eziyishumi, ngokwesibonelo, cindezela u-110(;) 10.

Ungenza imisebenzi ekhonjiwe ngenhla nganoma iyiphi indlela, futhi awuphoqelekile ukwenza lokho okukhonjisiwe ngenhla kuphela.

Ngenkathi ufaka ukwaziswa noma ngemuva kokuthi ufake ukwaziswa kwakho kwaphumelela, ungasebenzisa lezi zinkinobho kanye ukuze ubheke ukwaziswa okufakile. Uma ufaka ukwaziswa okuningi okufanayo usebenzisa i-(;) ((;) ku-fx-220 PLUS) ukuze ucacise imvamisa yokwaziswa (inombolo yezinto eziwukwaziswa) njengoba kuchaziwe ngenhla, ukupheqapheqa kukwaziswa kubonisa kokubili into ekukwaziswa kwakho kanye neskrini esihlukile semvamisa yokwaziswa kwakho (Freq).

Ngemva kwalokho, ungayilungisa imininingwane ebonisiwe, uma uthanda. Faka inani elisha bese ucindezela inkinobho ukufaka inani elisha esikhundleni selidala. Lokhu kusho nokuthi uma ufuna ukwenza neminye imisebenzi (ukubala, ukukhumbula imiphumela yezibalo zestathistiksi, njll), kufanele njalo uchofoze inkinobho kuqala ukuze uvale i-display yedatha.

Cindezela le inkinobho esikhundleni sale ngemuva kokushintsha inani elibonisiwe bhalisa inani elisha njengokwazisa okusha okufakiwe, futhi ushiye inani elidala njengoba linjalo.

Ungasusa inani lemininingwane elibonisiwe usebenzisa u ngokuchofoza u (CL). Ukususa inani lemininingwane kubangela ukuthi wonke amanani alandelayo agudlukele phezulu.

Amanani emininingwane owabhalisile ngokuvamile agcinwa enkumbulweni yomshini wokubala. Uma umlayezo othi "Data Full" uvela angeke ukwazi ukufaka noma imiphi imininingwane eyengeziwe uma kungekho isikhala esisele ukugcina imininingwane. Uma lokhu kwenzeka, cindezela inkinobho ukuveza isikrini esiboniswe ngezansi.

Ukususa imininingwane osanda kuyifaka, cindezela u (CL).

Emva kokufaka imininingwane yezibalo Ohlelweni lwe-SD noma Ohlelweni lwe-REG, angeke usakwazi ukubonisa noma ukulungisa imininingwane ethile ngemuva kokusebenzisa noma ikuphi kulokhu okulandelayo.

Kuyi-SD Mode ne-REG Mode, le nkinobho isebenza njengale nkinobho.

Ukufaka Uhlelo lwe-REG kuzoveza izikrini ezinjengalezo eziboniswe ngezansi.

Cindezela inkinobho (, , noma ) ehambisana nohlobo lokulinganisa ofisa ukulusebenzisa.

Qala njalo ngokufaka u-(CLR)(Scl) ukususa imininingwane yezibalo.

Idatha yokufaka usebenzisa ukulandelana kwesihluthulelo okuboniswe ngezansi.

Amagugu akhiqizwa ukubalwa kokunciphisa kuxhomeke ekufakweni kwezindinganiso, futhi imiphumela ingakhunjulwa usebenzisa imisebenzi yokuhlunga eboniswe etafuleni elingezansi.

Itafula elilandelayo libonisa imisebenzi echofozekayo okufanele uyisebenzise ukubuyisa imiphumela esimweni senombolo eshintshayo esa-sanxande.

Amanani akwitafula elingenhla angasetshenziswa ngaphakathi kwezinkulumo ngendlela efanayo nalapho usebenzisa izinombolo ezishintshashintshayo.

Izinombolo ezishintshayo ezihamba emgqeni

Ifomula yezinombolo ezishintshayo ezihamba emgqeni ithi: y = A + Bx.

Isibonelo: Ukucindezela Kwesimo Somoya vs. Ukushisa

Yenza Izinombolo ezishintshayo zihambe emgqeni ukucacisa imigomo yefomula yokuhlanganisa kanye neyenombolo ephindaphindayo yokwaziswa okusezansi.

Okulandelayo, sebenzisa ifomula yezinombolo ezishintshayo ukuqagela ukucindezela komoya ku -5°C nokushisa ku-1000 hPa. Okokugcina, bala izinombolo eziphindaphindayo zomphumela (r2) nesibonelo se-covariance (^{∑xy - n∙x-∙y-}_{n - 1}).

Sebenzisa imisebenzi efanayo echofozekayo neyezInombolo ezishintshayo ukubuyisa imiphumela yalezi zinhlobo zezInombolo ezishintshayo.

Lokhu okulandelayo kubonisa amafomula ezinombolo ezishintshayo ngohlobo ngalunye.

Izinombolo Ezishintshayo Ezisasanxande

Ifomula yezinombolo ezishintshayo ezisasanxande ithi: y = A + Bx + Cx2.

Isibonelo:

Yenza isibalo sezinombolo ezishintshayo ukunquma imibandela yefomula yezinombolo ezishintshayo.

Qaphela Ukwaziswa Okufakayo

ukufaka idatha eyodwa kabili.

Ungaphinda ufake ukwaziswa okufanayo kaningana usebenzisa (;). Faka idatha "engu-20 nengu-30" izikhathi ezinhlanu, ngokwesibonelo, chofoza u-20 30 (;) 5.

Imiphumela engenhla ingatholakala nganoma iyphi indlela, hhayi kuphela ngale eboniswe ngenhla.

Ukuqapha lapho uhlela ukwaziswa okufakayo kwe-ukwehluka okuvamile kuyathinteka nakwizibalo zezinombolo ezishintshayo.

Ungasebenzisi izinombolo eziguquguqukayo kusuka ku-A kuyofika ku-F, X, noma nano-Y ukugcina ukwaziswa uma wenza izibalo zamanani aqoqiwe. Lezi zinombolo eziguquguqukayo zisetshenziselwa izibalo zokwaziswa okuzogcinwa okwesikhashana, ngakho-ke noma yikuphi ukwaziswa ongase ukufake lapho kungashintshwa amanye amanani uma sekubalwa izibalo zokwaziswa okuqoqiwe.

Ukufaka umsebenzi we-REG bese ukhetha uhlobo lokusebenza lwezinombolo ezishintshayo (Lin, Log, Exp, Pwr, Inv, Quad) izinombolo eziguquguqukayo ezicacile njengo-A kuye ku-F, X, nako-Y. Ukushintsha usuka kolunye uhlobo lwezinombolo ezishintshayo uye kolunye ngaphakathi kokusebenza kwe-REG kuyazisula ezinye izinombolo eziguquguqukayo.
