LEEM-7 Solenoid Magnetic Field Measurement Apparatus

Kev Piav Qhia Luv:

Nws yog ib qho kev sim tseem ceeb hauv kev qhia txog kev sim physics hauv cov tsev kawm qib siab los ntsuas qhov kev faib tawm ntawm lub zog sib nqus hauv galvanical solenoid los ntawm kev siv Hall unit. Lub tshuab ntsuas lub zog sib nqus ntawm Solenoid siv lub tshuab linear Hall unit uas tau sib xyaw ua ke los ntsuas lub zog sib nqus tsis muaj zog hauv 0-67 mT ntawm galvanical solenoid, yog li daws qhov kev rhiab heev ntawm Hall unit, kev cuam tshuam ntawm qhov hluav taws xob seem, kev tsis ruaj khov ntawm cov zis los ntawm qhov kub nce ntawm solenoid thiab lwm yam tsis zoo, uas tuaj yeem ntsuas qhov kev faib tawm ntawm lub zog sib nqus ntawm galvanical solenoid kom raug, nkag siab thiab nkag siab txog lub hauv paus ntsiab lus thiab txoj kev ntsuas lub zog sib nqus los ntawm cov ntsiab lus linear Hall thiab kawm txoj kev ntsuas qhov rhiab heev ntawm Hall unit. Xav txog qhov xav tau ntev ntawm kev qhia cov khoom siv sim, lub zog thiab lub sensor ntawm lub tshuab no kuj muaj cov cuab yeej tiv thaiv.

Cov khoom siv no muaj ntau yam khoom siv, tsim qauv zoo, siv tau zoo, muaj kev nkag siab zoo, thiab cov ntaub ntawv ruaj khov, thiab siv tau rau kev sim physics hauv tsev kawm qib siab. Cov khoom siv no siv tau rau kev sim lub cev yooj yim, kev sim sensor ntawm chav kawm "sensor principle", thiab kev sim hauv chav kawm ntawm cov tub ntxhais kawm qib siab thiab cov tub ntxhais kawm theem nrab.
