Hlau Detectors tseem ceeb

Detectors hlau yuav ntes tsis txhais tes xwb thiaj tseem ntes npib, hauv lub lag luam thiab lwm yam xov.

Nyob lub teb archaeology, feem ntau yuav teev cia yog los ntawm cov hlau, xws li cia nyias qhov hluav taws kub, cartridges, txhob, zoo li artillery, suab thiab cov ntaj, tej pov thawj uas yog nyob rau lub sij hawm keeb kwm ntawm tsov rog coj qhov chaw. Li no, archaeologists hauv lub tshav pob qhov tseem ceeb tshaj plaws uas yog ib tug yooj yim hlau ntes.

Hlau detectors yeej qhia siv los pab deg penetrating radar (SPR, nto Radar Penetrating) thiab lwm yam hauv pem teb ces radar suab.
