Txog Zhenan
Zhenan ib txwm ua raws li kev ua lag luam lub tswv yim ntawm "Zoo ua ntej, kev pabcuam ua ntej" thiab ua rau nws lub tswv yim txuas ntxiv rau nws cov corporate kab lis kev cai. Nyob rau hauv lub xyoo pua tshiab no, peb tau mob siab rau kev sib koom tes nrog txhua qhov kev lag luam rau kev sib nrig sib, muab cov kev xav zoo thiab kev txawj ntse, ncaj ncees.
Lub tuam txhab tau cog lus los ua haujlwm tes ua ke nrog cov neeg siv khoom los tsim lub neej tom ntej zoo dua.

Siv thiab ua haujlwm ntawm graphite li electrodes
Resistivity muaj nuj nqis thiab kev ua tau zoo:
The resistivity of graphite is approximately 8–10 × 10⁻⁶ Ω·m at room temperature. Ntawm qhov kub thiab txias, kev tawm tsam tsis kam lees los ntawm 10-20%.
Resistivity yog ib qho kev ua tau zoo ntawm lub cev ntawm graphite li electrodes. Nws qhia txog qib ntawm Graphitization: qhov qis dua cov thermal conductivity thiab qhov zoo dua cov anti-oxidation kev ua tau zoo.
Qhov kev tso cai tam sim no tsis txaus ntseeg ntawm graphite raws li electrode thaum siv yog cuam tshuam nrog nws txoj kev tiv taus thiab lub taub. Txo kev tiv thaiv rau qhov siab dua tam sim no, tab sis qhov kev pub ceev tam sim no yog qhov ua kom lub taub hau hluav taws xob.
Conductivity thiab kev sib raug zoo:
Hauv cov hlau, kev coj ua tau zoo nrog kev nce qib kub.
Nyob rau hauv semiconductors, conductivity nce nrog nce kub.
Cim npe nrov: Graphite rau machining, Tuam Tshoj graphite rau cov tshuab luam ntawv, lwm tus neeg, Hoobkas
