LADP-1A Nidaamka Tijaabada ee CW NMR - Qaabka Sare
Sharaxaada
Qaybta ikhtiyaariga ah: Mitirka soo noqnoqda, qayb is-diyaar ah oscilloscope
Nidaamkan tijaabada ah ee mawjadaha magnetka ee joogtada ah ee nukliyeerka (CW-NMR) wuxuu ka kooban yahay magnet isku mid ah oo sarreeya iyo cutubka mashiinka ugu muhiimsan.Magnet joogto ah ayaa loo isticmaalaa in lagu bixiyo goob birlabeedka aasaasiga ah oo ay ku kor sarreyso goob koronto oo la hagaajin karo, oo ay abuureen labo gariirood, si loogu oggolaado hagaajinta guud ee goobta magnetka iyo in loo magdhabo isbedbedelka goobta magnetic ee ay sababto kala duwanaanshaha heerkulka.
Sababtoo ah kaliya magnetizing yar oo hadda ah ayaa loo baahan yahay goobta korantada ee aadka u hooseeya, dhibaatada kuleylka nidaamka waa la yareeyaa.Markaa, nidaamka waxa uu si joogto ah u shaqayn karaa dhawr saacadood.Waa qalab tijaabo ah oo ku habboon shaybaarada fiisigiska ee horumarsan.
Tijaabi
1. Si loo ilaaliyo ifafaale resonance magnetka nukliyeerka (NMR) ee hydrogen nuclei ee biyaha iyo isbarbardhigga saameynta ions paramagnetic;
2. Si loo cabbiro halbeegyada nuclei-yada hydrogen-ka iyo nuclei-yada fluorine, sida saamiga magnet-ka spin, factor Lande g, iwm.
