LADP-2 Experimental System of Pulsed NMR

Lus piav qhia luv luv:

Pulsed Fourier hloov nuclear magnetic resonance siv pulsed RF teb los ua ntawm lub nuclear system los soj ntsuam cov lus teb ntawm lub nuclear system mus rau mem tes, thiab siv ceev ceev Fourier transform (FFT) technology los hloov lub sij hawm domain teeb liab mus rau zaus domain signal, uas yog. sib npaug rau ntau zaus nruam nthwv dej nuclear sib nqus resonance spectrometers zoo siab nyob rau tib lub sijhawm, yog li qhov tshwm sim ntawm nuclear magnetic resonance tshwm sim tuaj yeem pom nyob rau hauv ntau yam, thiab cov teeb liab ruaj khov Tam sim no, pulse txoj kev siv nyob rau hauv feem ntau NMR spectrometers, thaum. Pulse method yog siv hauv MRI.

Kev sim

1. Nkag siab txog qhov kev xav ntawm lub cev thiab qhov kev sim ntawm cov txheej txheem PNMR.Kawm piav qhia txog lub cev tshwm sim hauv PNMR siv cov qauv vector classical.

2. Kawm siv cov cim ntawm spinecho (SE) thiab dawb induction decay (FID) los ntsuas T₂(spin-spin so lub sij hawm).Txheeb xyuas qhov cuam tshuam ntawm magnetic teb homogeneity ntawm NMR teeb liab.

3. Kawm ntsuas T₁(spin-lattice so lub sij hawm) siv rov qab rov qab.

4. Ua tib zoo nkag siab txog cov txheej txheem so kom txaus, saib xyuas cov txiaj ntsig ntawm paramagnetic ions ntawm lub sijhawm so nuclear.

5. Ntsuas T₂ntawm tooj liab sulfate tov ntawm txawv concentrations.Txiav txim siab qhov kev sib raug zoo ntawm T₂nrog rau kev hloov ntawm concentration.

6. Ntsuas qhov txheeb ze tshuaj hloov chaw ntawm tus qauv.
