Uhlelo Lokuhlola lwe-LADP-2 lwe-NMR edonswayo
I-Pulsed Fourier iguqulela i-resonance kazibuthe wenuzi isebenzisa insimu ye-RF eshaywayo ukusebenza ohlelweni lwenuzi ukubona ukuphendula kohlelo lwenuzi ku-pulse, futhi isebenzisa ubuchwepheshe obusheshayo be-Fourier transform (FFT) ukuguqula isignali yesizinda yesikhathi ibe yisiginali yesizinda semvamisa, okuyi okulingana nemvamisa eyodwa eqhubekayo yamagagasi e-magnetic resonance spectrometers ajabule ngasikhathi sinye, ngakho-ke isimangaliso se-nuclear magnetic resonance singabonwa ebangeni elikhulu, futhi isinali lizinzile Njengamanje, indlela ye-pulse isetshenziswa kuma-spectrometer amaningi e-NMR, ngenkathi indlela ye-pulse isetshenziswa ku-MRI.
Ukuhlolwa
1. Qonda umbono oyisisekelo womzimba nokulungiswa kohlelo lwe-PNMR. Funda ukuchaza izinto ezihlobene ngokomzimba ku-PNMR usebenzisa imodeli ye-vector yakudala.
2. Funda ukusebenzisa amasiginali we-spin echo (SE) nokubola kokungeniswa kwamahhala (FID) ukukala u-T2(isikhathi sokuphumula se-spin-spin). Hlaziya ithonya le-magnetic field homogeneity kusiginali ye-NMR.
3. Funda ukukala u-T1 (isikhathi sokuphumula se-spin-lattice) usebenzisa ukutakula okuphindayo.
4. Ukuqonda ngokufanele indlela yokuphumula, bheka umphumela we-ion paramagnetic esikhathini sokuphumula kwenuzi.
5. Linganisa u-T2Isixazululo se-copper sulfate ezindaweni ezahlukahlukene. Thola ubudlelwane be-T2 ngokushintsha kokuhlushwa.
6. Linganisa ukufuduka kwamakhemikhali okuhlobene kwesampula.
