4. DISTINTITE NTA NTAWM KARMA XAV HLAU
1) Pib nrog Nickel Chromium Cov Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob 1, peb hloov qee yam ntawm NI nrog
Al thiab lwm cov ntsiab lus, thiab yog li ua tiav qhov ua kom precision tiv thaiv cov khoom nrog kev txhim kho
Kuj kub cov coefficient thiab tshav kub hluav taws xob yuam kev tawm tsam tooj liab.
Nrog qhov sib ntxiv ntawm al, peb tau ua tiav hauv kev ua cov ntim tiv taus 1.2 npaug ntau dua
Tshaj li Nickel Chromium Cov Hlau Hluav Taws Xob Hluav Taws Xob Hlau 1 thiab lub zog tensile 1.3 npaug ntau dua.
2) Qhov ntsuas kub thib ob vibe shoefficient β ntawm karmalloy hlau kmw yog me me, - 0.03 × 10-6 / k2,
thiab cov kab mob kub ua rau muaj kev sib tw kub hnyiab kom yuav luag yog yuav luag ib txoj kab ncaj nraim
ntau yam.
Yog li ntawd, ntsuas kub coefficient yog teeb tsa los ua 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
yuav tau saws rau cov coefficietly.
3) Kev quab yuam electromive tawm tsam tooj liab ntawm 1 ~ 100 ° C kuj yog me me, hauv qab + + 2 μv / k, thiab
Cov khoom ua pov thawj zoo heev ruaj khov nyob rau ib lub sijhawm ntau xyoo.
4) Yog tias qhov no yog siv los ua cov khoom siv precision tiv thaiv, tsis tshua muaj kub kho cua sov yog
Yuav tsum tau tshem tawm kev ua kom muaj kev sib txawv raws li xws li manganin xaim cmw.
