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>, thiab yog li ua kom muaj kev cuam tshuam nrog kub thiab kub thiab thaum tshav kub kub.
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 yus kub hnyiab kom yuav luag txhua txoj kab ncaj nraim hauv qhov kub ntau.
Yog li ntawd, ntsuas kub coefficient yog teeb tsa los yog qhov nruab nrab coefficient nruab nrab ntawm 23 ~ 5,6 / k, nruab nrab kub coefficient ntawm 0 ~ 100 ° C, kuj yuav
yuav tau saws rau cov coefficietly.
3) Kev quab yuam electromotive tawm tsam tooj liab ntawm 1 ~ 100 ° C kuj me me, hauv qab + + + ntawm + + thiab ua kom pom tau zoo heev nyob rau lub sijhawm ntau xyoo.
4) Yog tias qhov no yog siv los ua qhov kev kho kom sov ceev, cov kub kub yuav tsum tau tshem tawm cov kev ua kom zoo ib yam nkaus li hauv manganin hlau CMW.
