Dab tsi yog carbon txhuam?

Cov txhuam hniav kuj hu ua hluav taws xob txhuam thiab tau siv dav hauv ntau yam khoom siv hluav taws xob.

Cov khoom siv tseem ceeb siv hauv cov txhuam hniav yog graphite.

Cov pa roj carbon txhuam yog cov khoom siv hloov hluav taws xob lossis cov teeb liab nruab nrab ntawm qhov chaw ruaj khov thiab qhov sib hloov ntawm lub cev muaj zog, lub tshuab hluav taws xob lossis lwm lub tshuab tig.

Lawv feem ntau yog ua los ntawm cov pa roj carbon ntshiab thiab coagulant.

Lawv feem ntau yog square nyob rau hauv cov duab thiab daig ntawm ib tug hlau bracket.

Muaj lub caij nplooj ntoos hlav sab hauv los nias nws nruj nreem rau ntawm ncej.

Thaum lub cev muaj zog tig, lub zog hluav taws xob xa mus rau lub coil los ntawm lub commutator.

Vim tias nws cov khoom tseem ceeb yog carbon, nws yog hu ua carbon txhuam thiab nws yooj yim hnav.

Nws yuav tsum tau tu thiab hloov tsis tu ncua, thiab cov pa roj carbon deposits yuav tsum tau ntxuav.
