4. Izici ezihlukile ze-karma ukumelana nocingo
1) Ukuqala ngeNickel Chromium Electric Heat Wire Wire Wire Wire 1, sangena esikhundleni seNI nge
Al kanye nezinye izinto, futhi ngaleyo ndlela uthole impahla yokumelana enembile ethuthukisiwe
Ukumelana nokushisa okuhlangene futhi kushisa amandla e-electromotive amelene yethusi.
Ngokungezwa kwe-al, siphumelele ekwenzeni i-volume ukumelana nezikhathi eziyi-12
Kunesilinganiselo se-nickel chromium kagesi sokushisa i-wire wire 1 kanye namandla ashubile aphindwe izikhathi eziyi-1.3.
2) I-couffient ye-Secondaretelite Cooffient ye-karmalloy wire KMW incane kakhulu, - 0.03 × 10-6-6 / K2, futhi ijika lokushisa lokumelana liphenduka libe umugqa oqondile ngaphakathi
ububanzi bokushisa.
Ngakho-ke, i-coeffienty yokushisa isethwe ukuba ibe yi-coeffient yokushisa ephakathi phakathi
23 ~ 53 ° C, kepha 1 × 10-6 / K, okuphakathi kokushisa okuhlanganisiwe phakathi kuka-0 ~ 100 ° C, nakho
yamukelwe i-coefficient yokushisa.
3) Amandla we-electromotive ngokumelene wethusi phakathi kuka-1 ~ 100 ° C nawo omncane, ngezansi + 2 μv / k, futhi
kukhombisa ukuqina okuhle esikhathini esiyiminyaka eminingi.
4) Uma lokhu kufanele kusetshenziswe njengento yokumelana nenembile, ukwelashwa okushisa okuphansi kokushisa
Kuyadingeka ukuqeda ukuhlanekezelwa kokucubungula njengasemongweni lwe-mangani.
