3-AXIS Helmholtz Coil Performance Test Report

 

1. Txheej txheem cej luam

1) Lub Hom Phiaj Xeem
① Los ntawm kev soj ntsuam ntawm cov txiaj ntsig kev xeem, kev ntsuam xyuas ntawm cov khoom ua tau zoo tau txais;
② Ntsuam xyuas seb cov khoom kuaj puas ua tau raws li qhov yuav tsum tau ua;
③ Muab cov ntaub ntawv siv rau cov khoom tsim thiab kev pab cuam tom qab muag, thiab muab lub hauv paus muaj zog rau kev tawm hauv lub hoobkas.
2) Cov ntaub ntawv yooj yim
Serial Number: DXLT231011-422 Khoom qauv: 3DXHC12. 5-1
Khoom npe: 3-AXIS Helmholtz Coil Lub sijhawm kuaj: Peb Hlis 24, 2023
3) Kev xeem ib puag ncig
Kev tshawb nrhiav ib puag ncig xaiv tau ze dua rau qhov tseeb ib puag ncig uas siv los ntawm tus neeg siv, suav nrog yam xws li cov hlau lead ntev thiab qhov kub thiab txias. Lub sij hawm raug xaiv nyob rau hauv lub sij hawm luv luv thaum qhov hloov pauv ntawm geomagnetic teb me me. Ua ntej qhov kev xeem, cov cuab yeej xav tau rau kev xeem tau qhib thiab ua kom sov ua ntej, thiab qhov ntsuas qhov ntsuas tau raug kaw, raws li qhia hauv Table 1.
