4. Cov yam ntxwv tshwj xeeb ntawm Karma kuj hlau
1) Pib nrog Nickel Chromium hluav taws xob cua sov hlau Chav Kawm 1, peb hloov qee qhov Ni nrog
Al thiab lwm cov ntsiab lus, thiab yog li ua tiav cov khoom siv tsis zoo nrog kev txhim kho
kuj kub 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 yog me me, - 0.03 × 10-6 / K2, thiab qhov kub thiab txias nkhaus hloov mus yuav luag ib txoj kab ncaj nraim hauv qhov dav
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 tuaj yeem
tau txais kev pom zoo rau qhov kub coefficient.
3) Electromotive quab yuam tiv thaiv tooj liab ntawm 1 ~ 100 ° C kuj me me, hauv qab + 2 μV / K, thiab
pom zoo stability nyob rau hauv ib lub sij hawm ntawm ntau xyoo.
4) Yog tias qhov no yuav tsum tau siv los ua cov khoom siv tsis zoo, kev kho cua sov qis yog
yuav tsum tau tshem tawm cov kev ua distortions ib yam li nyob rau hauv cov ntaub ntawv ntawm Manganin hlau CMW.
