Tus qauv ua haujlwm ntawm lub tshuab luam ntawv thermal yog tias soob hoom kub soob hoom kub soob hoom yog qhov chaw luam tawm. Tom qab lub taub hau tshuab luam yeeb thiab tiv toj rau cov ntawv luam thermal, cov qauv uas yuav tsum tau luam tawm. Lub hauv paus ntsiab lus yog zoo ib yam li ntawd ntawm lub khob cij fax tshuab. Daim duab yog tsim los ntawm cov cua sov, ua rau cov tshuaj lom neeg cov tshuaj tiv thaiv hauv zaj duab xis. Qhov no thermal tshuab luam ntawv tshuaj lom neeg yog nqa tawm ntawm ib qho kub. Kev kub siab yuav ua kom nrawm dua cov tshuaj tiv thaiv no. Thaum qhov kub nyob qis dua 60 degree, nws siv sijhawm ntev, txawm tias ob peb xyoos, rau daim ntawv los ua kev tsaus ntuj; Thiab thaum qhov ntsuas kub yog 200 degree, qhov yeeb yam no yuav ua tiav hauv ob peb microconds.
