LADP-2 Tsarin Gwaji na Pulsed NMR

Takaitaccen Bayani:

Pulsed Fourier yana canza ƙarfin maganadisu na nukiliya yana amfani da filin RF mai bugun jini don yin aiki akan tsarin nukiliya don lura da martanin tsarin nukiliya zuwa bugun jini, kuma yana amfani da fasaha mai saurin canzawa na Fourier (FFT) don canza siginar yankin lokaci zuwa siginar yanki, wanda shine daidai da mahara guda daya ci gaba da kalaman nukiliya Magnetic resonance spectrometers suna farin ciki a lokaci guda, don haka za a iya lura da makaman nukiliya sabon abu a cikin babban kewayon, kuma siginar yana da karko A halin yanzu, ana amfani da hanyar bugun jini a mafi yawan na'urorin NMR, yayin da Ana amfani da hanyar bugun jini a cikin MRI.

1. Fahimtar ainihin ka'idar jiki da tsarin gwaji na tsarin PNMR.Koyi don bayyana abubuwan al'amuran zahiri masu alaƙa a cikin PNMR ta amfani da ƙirar vector na gargajiya.

2. Koyi amfani da sigina na spin echo (SE) da lalata shigar da kyauta (FID) don auna T₂(lokacin shakatawa-spin-spin shakatawa).Yi nazarin tasirin yanayin yanayin maganadisu akan siginar NMR.

3. Koyi auna T₁(lokacin shakatawa na juyi-lattice) ta amfani da dawo da baya.

4. Da kyau fahimtar tsarin shakatawa, lura da tasirin paramagnetic ions akan lokacin hutun nukiliya.

5. Auna T₂na jan karfe sulfate bayani a daban-daban yawa.Tabbatar da dangantakar T₂tare da canjin maida hankali.

6. Auna mahaɗin mahaɗin sinadarai na samfurin.
