LADP-2 Gwajin Gwajin na NMR

Short Bayani:

Bayanin Samfura

Alamar samfur

Pulsed Fourier ya canza murfin maganadisu na nukiliya yana amfani da filin RF mai bugawa don aiki akan tsarin nukiliya don lura da martanin tsarin nukiliya zuwa bugun jini, kuma yana amfani da fasaha mai sauri Fourier (FFT) don canza siginar yankin lokaci zuwa siginar yanki mitar, wanda shine yayi daidai da mitar yanayi guda daya mai ci gaba da motsa jiki na maganadisu mai birgewa a lokaci guda, saboda haka ana iya lura da yanayin rawar maganadisu a cikin babban kewayo, kuma siginar ta tabbata A halin yanzu, ana amfani da hanyar bugun jini a mafi yawan masu kallo na NMR, yayin da ana amfani da hanyar bugun jini a cikin MRI.

Gwaje-gwaje

1. Fahimci ainihin ka'idar jiki da gwajin gwaji na tsarin PNMR. Koyi don bayanin abubuwan da suka shafi jiki a cikin PNMR ta amfani da samfurin vector na gargajiya.

2. Koyi amfani da sigina na amsa kuwwa (SE) da lalacewar shigar da abubuwa kyauta (FID) don auna T₂(lokacin hutawa-juyawa). Yi nazarin tasirin haɓakar haɓakar maganadisu akan siginar NMR.

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

4. Ingancin fahimtar tsarin shakatawa, lura da tasirin ion paramagnetic akan lokacin shakatawa na nukiliya.

5. Auna T₂na jan karfe sulfate bayani a daban-daban yawa. Dayyade dangantakar T₂ tare da canjin natsuwa.

6. Auna matsar sinadaran dangi na samfurin.
