4. Mawonekedwe osiyana a karma kukana waya wa karma kukana
1) Kuyambira ndi Nickel Chromium Strette Teari Class 1, tidasinthira ena a NI ndi
Al ndi zinthu zina, ndipo mwakutero adakwaniritsa zinthu zogwirizana ndi kusintha
Kukhazikitsa kutentha kutentha kokwanira ndi kutentha thupi molingana ndi mkuwa.
Ndi kuwonjezera kwa al, tachita bwino popanga kuchuluka kwa kuchuluka kwa kasupe 1.2
kuposa chromium chromium yamagetsi yopanga ma waya 1 ndi mphamvu yayikulu 1.3 Kambirimbiri.
2) Kutentha kwachiwiri kogwirizana ndi waya wa kormalloy ndi kochepa kwambiri, - 0.03 × 10-6 / k2,
ndipo kutentha kwa kutentha kumayamba kukhala pafupi ndi mzere wowongoka mkati mwake
mitundu.
Chifukwa chake, kutentha kwa kutentha kumakhazikitsidwa kukhala kutentha kwamphamvu pakati
23 ~ 53 ° C, koma 1 × 10-6 / k, kutentha kwapakatikati pakati pa 0 ~ 100 ° C Gawo Cetrel
khalani olandiridwa kutentha kwa kutentha.
3) Magetsi amagetsi motsutsana ndi mkuwa pakati pa 1 ~ 100 ° C ndi yaying'ono, pansi pa + 2 μV / k, ndipo
imawonetsa bwino kwambiri kwa zaka zambiri.
4) Ngati izi zikuyenera kugwiritsidwa ntchito ngati chogwiritsira ntchito moyenera, mankhwala otsika kutentha ndi
amafunikira kuti athetse kusuntha monga momwe ziliri kwa manginin waya wa mangin.
