Nidaamka Tijaabada LADP-2 ee Pulsed NMR Sawirka Soo-bandhigay

Nidaamka Tijaabada LADP-2 ee NMR-ka Pulsed

Sharaxaad Gaaban:

Falcelinta magnetic-ka nukliyeerka ee Pulsed Fourier waxay isticmaashaa goobta RF ee garaaca wadnaha si ay uga shaqeyso nidaamka nukliyeerka si ay u daawato jawaabta nidaamka nukliyeerka ee garaaca wadnaha, waxayna isticmaashaa tignoolajiyada Fourier ee degdega ah (FFT) si ay calaamadda waqtiga ugu beddesho calaamadda domain-ka soo noqnoqda, taas oo u dhiganta tiro badan oo ah mawjado joogto ah oo isku mar ah oo spectrometers-ka resonance magnetic-ka nukliyeerka ayaa isku mar la farxaa, sidaa darteed ifafaalaha resonance magnetic-ka nukliyeerka waxaa lagu arki karaa tiro badan, calaamadduna waa mid deggan. Waqtigan xaadirka ah, habka garaaca wadnaha waxaa loo isticmaalaa inta badan spectrometer-yada NMR, halka habka garaaca wadnaha loo isticmaalo MRI.

Faahfaahinta Badeecada

Calaamadaha Alaabta

Tijaabooyin

1. Fahmaan aragtida aasaasiga ah ee fiisikiska iyo habaynta tijaabada ee nidaamka PNMR. Baro inaad sharaxdo dhacdooyinka fiisikiska ee la xiriira PNMR adoo isticmaalaya qaabka vector-ka caadiga ah.

2. Baro inaad isticmaasho calaamadaha isbeddelka wareegga (SE) iyo burburka firfircoonida (FID) si aad u cabbirto T.₂(waqtiga nasashada wareegga-wareejinta). Falanqee saameynta isku-dhafka goobta birlabta ee calaamadda NMR.

3. Baro sida loo cabbiro T₁(waqtiga nasashada ee wareegga-lattice) iyadoo la isticmaalayo soo kabashada dib u soo noqoshada.

4. Si tayo leh u fahma habka nasashada, u fiirso saameynta ay aashitada paramagnetic-ku ku leeyihiin waqtiga nasashada nukliyeerka.

5. Cabbir T₂xalka naxaasta sulfate ee ku jira xaddi kala duwan. Go'aami xiriirka ka dhexeeya T iyo T.₂iyadoo la beddelayo feejignaanta.

6. Cabbir kala-guurka kiimikada ee muunadda.
