Inkqubo ye-LADP-2 yoVavanyo lwe-NMR ye-Pulsed
I-Pulsed Fourier iguqula i-resonance yenyukliya esetyenziswayo isebenzisa intsimi ye-RF esebenza kwinkqubo yenyukliya ukujonga impendulo yenkqubo yenyukliya kwi-pulse, kwaye isebenzisa itekhnoloji ye-Fourier yokuguqula ngokukhawuleza (FFT) ukuguqula ixesha lesiginali kwisiginali yesiginali. ilingana nokuphindaphindeka kwamaza ombane oomatshini benyukliya abonwabileyo ngaxeshanye, ngoko ke into enokwenzeka ukuba ibonakale kwibala elikhulu, kwaye umqondiso uzinzile Okwangoku, indlela yokubetha isetyenziswa kwiindawo ezininzi zeNMR, ngelixa Indlela yokubetha isetyenziswa kwi-MRI.
Uvavanyo
1. Qonda ithiyori esisiseko yomzimba kunye novavanyo lovavanyo lwenkqubo yePNMR. Funda ukucacisa izinto ezinxulumene nomzimba kwi-PNMR usebenzisa imodeli yevector.
2. Funda ukusebenzisa imiqondiso ye-spin echo (SE) kunye nokubola kwe-induction yasimahla (FID) ukulinganisa uT2(ixesha lokuphumla lokujikeleza). Hlalutya ifuthe le-magnetic field homogeneity kwisiginali yeNMR.
3. Funda ukulinganisa uT1 (ixesha lokuphumla le-spin-lattice) usebenzisa ukubuyela umva kwakhona.
4. Ukuqonda ngokufanelekileyo indlela yokuphumla, jonga isiphumo se-paramagnetic ions ngexesha lokuphumla kwenyukliya.
5. Linganisa T2Isisombululo sobhedu sulphate kwiindawo ezahlukeneyo. Chonga ubudlelwane beT2 ngotshintsho lwexinzelelo.
6. Linganisa ukufuduswa kwemichiza okunxulumene nesampulu.
