LADP-1A Yekuedza System yeCW NMR - Yepamberi Model
Tsanangudzo
Sarudzo chikamu: Frequency mita, yakazvigadzirira chikamu oscilloscope
Iyi yekuyedza sisitimu yeinoenderera-wave nuclear magnetic resonance (CW-NMR) ine yakakwira homogeneity magineti uye main machine unit.Magineti echigarire anoshandiswa kupa iyo yekutanga magineti inokwidziridzwa neinogadziriswa magetsi emagetsi, inogadzirwa nepeya coil, kubvumira kugadziridzwa kwakanaka kune yakazara magineti uye kubhadhara magineti kushanduka kunokonzerwa nekusiyana kwetembiricha.
Nekuti chete diki magnetizing ikozvino inodiwa kune yakaderera magetsi emagetsi, dambudziko rekupisa reiyo system rinodzikiswa.Nokudaro, iyo system inogona kushandiswa nguva dzose kwemaawa akawanda.Icho chiridzwa chakanaka chekuyedza chemberi fizikisi marabhoritari.
Kuedza
1. Kucherechedza nuclear magnetic resonance (NMR) chiitiko chehydrogen nuclei mumvura uye kuenzanisa simba reparamagnetic ions;
2. Kuyera maparamendi ehydrogen nuclei uye fluorine nuclei, senge spin magineti ratio, Lande g factor, nezvimwe.
