LADP-1A Experimental System ya CW NMR - Advanced Model
Kufotokozera
Gawo losasankha:Mamita pafupipafupi, gawo lokonzekera la oscilloscope
Dongosolo loyesera la nyukiliya ya nyukiliya yopitilira (CW-NMR) imakhala ndi maginito apamwamba kwambiri komanso makina akulu.Maginito okhazikika amagwiritsidwa ntchito popereka gawo loyamba la maginito lomwe limapangidwa ndi maginito osinthika, opangidwa ndi ma coils, kulola kusintha kwamphamvu kwa maginito onse ndikubwezera kusinthasintha kwa maginito komwe kumachitika chifukwa cha kusintha kwa kutentha.
Chifukwa maginito ang'onoang'ono okha ndi omwe amafunikira pagawo lotsika kwambiri lamagetsi, vuto la kutentha kwa dongosololi limachepetsedwa.Choncho, dongosololi likhoza kuyendetsedwa mosalekeza kwa maola angapo.Ndi chida choyenera choyesera cha ma labotale apamwamba a physics.
Yesani
1. Kuyang'ana nyukiliya maginito resonance (NMR) chodabwitsa wa haidrojeni nuclei m'madzi ndi kuyerekezera chikoka cha paramagnetic ayoni;
2. Kuyeza magawo a nyukiliya wa haidrojeni ndi nuclei ya fluorine, monga spin magnetic ratio, Lande g factor, etc.
