leej twg tsim lub teeb ntev dua? A Brief History of Cov Lub teeb Xyoo 1802, tus kws tshuaj lom neeg Askiv Humphry Davy tsim hluav taws xob lub teeb los ntawm kev hla tam sim no los ntawm nyias strips ntawm platinum; dhau 75 xyoo tom ntej, nws cov kev sim yuav yog lub hauv paus ntawm ntau yam kev mob siab rau tsim kom ntev- kav ntev , ci ntsa iab lub teeb los ntawm rhaub filaments.
