Tsawg zog hluav taws xob hluav taws xob sib txawv
Kev siv hluav taws xob qis qis (LEED) yog ib txoj kev sim siv los txiav txim siab cov qauv saum npoo ntawm ib lub muaju. Nws siv hluav taws xob ua hluav taws xob qis hluav taws xob (20-200 eV) [1] los tso rau qhov qauv ua qauv tawg. Lub teeb pom kev tsim los ntawm cov hluav taws xob tsis sib txawv yog pom nyob rau ntawm phosphor screen kom paub qhov txawv ntawm cov qauv saum npoo ntawm cov qauv.
