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.

Kev Siv thiab Kev Ua Haujlwm ntawm Graphite Electrodes

Kev vam khom kub tiv thaiv:
Qhov tiv taus ntawm cov khoom siv graphite yog qhov kub-nyob. Feem ntau, conductivity tsis ncaj qha rau ntom ntom vim tias, raws li cov mis tsis kam, kev tsim tawm yuav tsum muaj nyob ntawm "tus neeg ua haujlwm hla ntu." Txawm li cas los xij, vim muaj cov vegs hauv cov khoom lag luam graphite, cov khoom sib txuas zoo rau cov khoom siv tam sim no raug txo kom tsawg. Raws li ib tug tshwm sim, kev tiv thaiv ntawm graphite (qhov inverse ntawm conductivity) muaj feem xyuam rau nws cov "ntim ntom ntom."

Resistivity thiab ntim ntom ntom:
Lub xub ntiag ntawm voids hauv graphite cov khoom txo cov khoom siv hla kev zoo rau kev ua haujlwm tam sim no. Yog li ntawd, qhov tsis kam ntawm graphite (qhov inverse ntawm kev ua haujlwm) yog cuam tshuam los ntawm nws cov "ntim ntom ntom."
