4. Tilmaamo kala duwan oo siligga caabbinta ee karma caabbinta
1) Laga bilaabo Nickel Koromium Heat Heat Heat Heat Chromium 1, waxaan ku beddelay qaar ka mid ah NI iyo walxaha kale, sidaas darteedna waxaan ku guuleystey walxaha iska caabinta heerkulka ee heerkulka iska caabinta iyo kuleylka xoogga korantada.
Iyada oo lagu daro in Al, waxaan ku guuleysanay inaanu codka ugu adkaysanno 1.2 jeer ka weyn
Marka loo eego nickel chromium koronto oo kulayl ah oo lagu xiro Fasalka 1 iyo xoogga khafiifka ah 1.3 jeer ka weyn.
2) Kartida heerkulka sare β ee Karmalloy Wire KMW waa mid aad u yar, - 0.03 × 10-6 / K2,
iyo qalooca heerkulka ee iska caabbinta waxay isu rogtay inay ku dhowaad xariiq toosan gudaha heerkul ballaaran.
Sidaa darteed, wadarta heerkulka ah ayaa loo dejiyey celceliska heerkulka celceliska heerkulka inta u dhexeysa 23 ° C, laakiin 1 × 10-0- K, celceliska heerkulka heerkulka ee u dhexeeya 0 ~ 100 ° C, sidoo kale waa laga yaabaa
loo qaadan karaa isbadal heerkulka ah.
3) Xoogga korantada ee ka dhexeeya 1 ~ 100 ° C sidoo kale, hoosta + 2 μV / k, oo muujinaya xasillooni heer sare ah muddo sannado badan.
4) Haddii tan loo istcimaalayo wax sax ah caabbinta saxda ah, daaweynta kuleylka heerkulka hooseeya ayaa loo baahan yahay si meesha looga saaro ka baaraandegista dhalaashaha ah sida kiiska Mandain Wire CMW.
