Xaiv ib feem: zaus ntsuas, tus kheej npaj ib feem oscilloscope
Qhov kev sim no ntawm kev nruam-wave nuclear magnetic resonance (CW-NMR) muaj cov hlau nplaum homogeneity siab thiab lub tshuab tseem ceeb.Cov hlau nplaum tas mus li yog siv los muab cov hlau nplaum loj tshaj plaws los ntawm kev hloov kho electromagnetic teb, tsim los ntawm ob lub coils, kom tso cai rau kev hloov kho kom zoo rau tag nrho cov magnetic teb thiab los them cov kev hloov pauv ntawm magnetic teb los ntawm qhov kub thiab txias.
Vim hais tias tsuas yog me me magnetizing tam sim no xav tau rau qhov tsis tshua muaj hluav taws xob electromagnetic, qhov teeb meem cua sov ntawm lub kaw lus raug txo kom tsawg.Yog li, lub kaw lus tuaj yeem ua haujlwm tsis tu ncua rau ob peb teev.Nws yog ib qho kev sim zoo tshaj plaws rau cov chaw kuaj physics siab heev.
Kev sim
1. Saib xyuas qhov tshwm sim ntawm nuclear magnetic resonance (NMR) phenomenon ntawm hydrogen nuclei hauv dej thiab sib piv cov kev cuam tshuam ntawm paramagnetic ions;
2. Txhawm rau ntsuas qhov tsis muaj hydrogen nuclei thiab fluorine nuclei, xws li spin magnetic ratio, Lande g factor, thiab lwm yam.
