Ntau npaum li cas 'meter' tuaj yeem ntes tau hlau ntes
Rau cov khoom uas muaj ib tug faus qhov tob ntawm tsib meters, nws yog tsim nyog los yuav ib tug hlau detector nrog ib tug tob ntawm txog yim meters los xyuas kom meej nws cov nyhuv. Qhov tob tob npaum li cas ntawm lub tshuab nqus hlau hauv av tuaj yeem ntes tsis tau tsuas yog cuam tshuam nrog lub ntes nws tus kheej, tab sis kuj muaj feem xyuam rau qhov chaw kuaj pom thiab cov hlau kuaj pom.
Feem ntau hais lus, kev tshawb nrhiav ntau yam ntawm cov hlau ntes ntawm lub khw yog cuam tshuam los ntawm ntau yam xws li hom, qauv, thiab qhov loj ntawm cov khoom kuaj pom. Cov hlau ntes feem ntau yog li 1 txog 40 cm, thiab cov coil hom underground hlau detector feem ntau yog 1-40 cm. Txog 15m, qhov ntev-ntev hlau ntes yog 1 txog 30 meters tob.
Qhov siab tshaj plaws nrhiav kom pom deb ntawm cov hlau ntes feem ntau yog tsau, uas feem ntau cuam tshuam nrog kho vajtse. Hauv kev siv tiag tiag, nws yuav tsis ncav cuag qhov ntsuas siab tshaj plaws vim muaj ntau yam laj thawj, xws li khoom loj, av zoo, thiab lwm yam, yog li yuav ua li cas? Puas tuaj yeem tshawb pom qhov deb ntawm cov hlau ntes tau nce?
Nyob rau hauv ib txwm muaj xwm txheej, qhov kev tshawb nrhiav qhov deb ntawm cov hlau ntes tau tsuas yog nce ntawm qhov theoretical qhov tob, thiab txoj kev txhim kho tshwj xeeb yog ua kom muaj qhov rhiab heev, tab sis txoj kev no yuav ua rau muaj kev ceeb toom tsis tseeb ntawm cov teeb liab thiab nce lub zog noj; Yog tias koj xav txhim kho Rau qhov siab tshaj plaws nrhiav kom pom qhov deb, qhov kev tshawb nrhiav kauj tuaj yeem hloov kho. Yog tias xav tau qhov kev kuaj pom loj dua, nws raug nquahu kom rov yuav lub ntsuas hlau nrog qhov pom qhov tob dua.
