4. Tilmaamaha gaarka ah ee siliga iska caabinta Karma
1) Laga bilaabo Nickel Chromium siligga kuleylka korantada ee fasalka 1, waxaan ku beddelnay qaar ka mid ah Niyada Al iyo walxo kale, waxaanan ku gaadhnay walxo iska caabin ah oo sax ah oo leh hufnaanta heerkulka iska caabinta oo la wanaajiyey iyo kulaylka kuleylka kuleylka
Marka lagu daro Al, waxaan ku guuleysanay inaan sameyno iska caabin mugga 1.2 jeer ka weyn
marka loo eego nickel Chromium siligga kulaylka korontada ee fasalka 1 iyo xoogga xajinta 1.3 jeer ka weyn.
2) Isku-xidhka heerkulka sare ee β ee siliga Karmalloy KMW waa mid aad u yar, - 0.03 × 10-6 / K2,
iyo qalooca heerkulka iska caabintu waxay noqotaa mid ku dhow xariiq toosan oo heerkul ballaaran ah.
Sidaa darteed, isku-xidhka heerkulka ayaa loo dejiyay inuu noqdo isku-xidhka heerkulka celceliska u dhexeeya 23 ~ 53 °C, laakiin 1 × 10-6/K, celceliska isku-xidhka heerkulka u dhexeeya 0 ~ 100 °C, sidoo kale waa laga yaabaa.
in loo qaato isku xidhka heerkulka.
3) Awoodda korantada ee ka soo horjeeda naxaasta inta u dhaxaysa 1 ~ 100 °C sidoo kale waa yar yahay, oo ka hooseeya + 2 μV/K, waxayna muujisaa xasillooni aad u wanaagsan muddo sanado ah.
4) Haddii tan loo isticmaalo sida walxaha iska caabbinta saxda ah, daawaynta kulaylka hooseeya ayaa loo baahan yahay si loo baabi'iyo qalloocinta farsamaynta sida kiiska Manganin siligga CMW.
