Cov Ntsiab Cai ntawm Kev Ntsuas Cov Khoom Siv Hlau

Cov txheej txheem kuaj cov khoom siv hlau yog ua raws li ntau yam kev tshawb fawb thiab tau siv dav hauv kev tsim khoom thiab kev tswj kom zoo. Lub hauv paus ntsiab lus ntawm electromagnetic induction, los ntawm kev txheeb xyuas cov eddy tam sim no thiab lawv qhov tsis sib haum ntawm cov khoom sib nqus tsim nyob rau hauv cov khoom hlau nyob rau hauv ib qho kev hloov magnetic teb (nrog rau qhov rhiab heev txog li 0.1 mm³ hlau hais), ua kom pom cov hlau, ua rau nws tsim nyog rau kev soj ntsuam kev nyab xeeb hauv cov khoom noj thiab tshuaj lag luam.

Qhov kev ntsuam xyuas siv siab - zaus hloov tam sim no (ntau zaus 1 kHz-10 MHz) los tsim cov eddy tam sim no hauv cov conductors, txheeb xyuas qhov tsis xws luag los ntawm kev hloov pauv hauv txoj kev tam sim no (nrhiav cov kab nrib pleb li 0.5 hli), thiab feem ntau yog siv rau qhov tsis yog - kev puas tsuaj ntawm cov kav dej. X-ray fluorescence tsom xam, los ntawm kev zoo siab hlau atoms kom emit tus yam ntxwv X-rays (lub zog daws teeb meem<150 eV), accurately determines elemental composition and plays a crucial role in alloy identification and precious metal recycling.
