4. Cov yam ntxwv tshwj xeeb ntawm Karma kuj xaim
1) Pib nrog Nickel Chromium hluav taws xob hluav taws xob cua sov hlau Chav Kawm 1, peb hloov qee qhov Ni nrog Al thiab lwm yam, thiab yog li ua tiav cov khoom siv tsis zoo nrog kev txhim kho qhov kub thiab txias coefficient thiab kub electromotive quab yuam tiv thaiv tooj liab.
Nrog rau qhov sib ntxiv ntawm Al, peb tau ua tiav hauv kev ua kom muaj zog tiv thaiv 1.2 npaug ntau dua
tshaj Nickel Chromium hluav taws xob hluav taws xob cua sov hlau Chav Kawm 1 thiab lub zog tensile 1.3 npaug ntau dua.
2) Qhov nruab nrab kub coefficient β ntawm Karmalloy hlau KMW tsawg heev, - 0.03 × 10-6 / K2,
thiab qhov ntsuas kub tsis kam hloov pauv yuav luag ib txoj kab ncaj nraim hauv qhov kub thiab txias.
Yog li ntawd, qhov kub coefficient yog teem rau qhov nruab nrab kub coefficient ntawm 23 ~ 53 ° C, tab sis 1 × 10-6 / K, qhov nruab nrab kub coefficient ntawm 0 ~ 100 ° C, kuj yuav
tau txais kev pom zoo rau qhov kub coefficient.
3) Electromotive quab yuam tiv thaiv tooj liab ntawm 1 ~ 100 ° C kuj yog me me, hauv qab + 2 μV / K, thiab nthuav tawm kev ruaj ntseg zoo nyob rau lub sijhawm ntau xyoo.
4) Yog tias qhov no yuav tsum tau siv los ua cov khoom siv tsis zoo, kev kho cua sov qis yuav tsum tau ua kom tshem tawm cov kev ua haujlwm tsis zoo ib yam li Manganin hlau CMW.
