4. Izici ezihlukile ze-karma ukumelana nocingo
1) Ukuqala nge-nickel Chromium Electric Heat Wire Wire Wire Class 1, sangena esikhundleni se-NI nezinye izinto, futhi ngaleyo ndlela sithole impahla yokumelana nenembe okunembile lokulinganisa lokulinganisa nokushisa amandla nge-flour.
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-Secondare Secondary Cooffients β ye-karmalloy wire KMW incane kakhulu, - 0.03 × 10-6-6 / K2,
Futhi ijika lokumelana lokumelana liphenduka libe cishe umugqa oqondile ngaphakathi kobubanzi bokushisa obubanzi.
Ngakho-ke, i-coeffienty yokushisa isethwe njenge-coeffient yokushisa ephakathi ephakathi kuka-23 ~ 53 ° C, kepha 1 × 10-6 / k, i-coeffient ephakathi yokushisa phakathi kuka-0 ~ 100 ° C, nayo ingahle
yamukelwe i-coefficient yokushisa.
3) Amandla we-electromotive ngokumelene wethusi phakathi kuka-1 ~ 100 ° C nawo omncane, ngezansi + 2 μv / k, futhi akhombisa ukuqina okuhle esikhathini esiyiminyaka eminingi.
4) Uma lokhu kufanele kusetshenziswe njengento yokumelana nenembe, ukwelashwa okushisa okuphansi kudingeka ukuqeda ukuhlanekezela kokucubungula njengasesimweni se-mangagan wire cmw.
