Resistance hlau yog ib tug hlau hlau nrog resistivity, xws li nickel-chromium hlau, constantan hlau, tungsten hlau thiab hais txog. Cov khoom siv hluav taws xob tiv thaiv hluav taws xob hauv lub cub hluav taws xob muaj ntau haiv neeg, thiab cov khoom siv hluav taws xob uas xav tau rau kev siv hluav taws xob sib txawv tsis zoo ib yam, thiab cov hauv qab no muab ntau yam ntaub ntawv ntawm hluav taws xob rau hluav taws xob tiv thaiv hlau:
Carbon zaj duab xis kuj hlau: ua los ntawm plating ib txheej ntawm cov pa roj carbon monoxide rau ntawm lub plooj (porcelain raj), thiab depositing crystalline carbon nyob rau hauv lub cev pob txha ntawm lub ceramic pas nrig, qhov kev ua tau zoo yog nruab nrab.
Hlau zaj duab xis kuj hlau: Cua sov cov hlau nyob rau hauv lub tshuab nqus tsev tswj qhov kev tiv thaiv los ntawm kev hloov lub thickness ntawm cov hlau zaj duab xis. Cov ntaub ntawv hlau nickel, chromium, tooj liab, tungsten thiab lwm yam.
Wirewound kuj xaim: ua los ntawm constantan los yog npib tsib xee-chromium alloy tsis kam hlau qhov txhab ntawm lub pob txha pob txha, lub zog siv hluav taws xob feem ntau yog ntau tshaj 1W.
Txuas: tiv thaiv hlau txheej txheej txheem: cov hlau tsis kam tsuas yog siv lub tshuab nqus tsev melting ntxiv rau electroslag remelting, thiab tom qab ntawd cov hlau ingot yog kub-forged billet, tom qab zoo sib tsoo ntawm lub billet, ces kub dov ua, tom qab kev kho cua sov ntawm kub dov disc sawb, thiab tom qab ntawd rov xaim kos duab, hydrogen tiv thaiv tshav kub kho annealing, kom txog rau thaum cov microfilament tiav lawm, thiab tom qab ntawd hydrogen tiv thaiv tshav kub kho annealing.
