LADP-1A Sistimi ea Teko ea CW NMR - Mohlala o tsoetseng pele
Tlhaloso
Karolo ea boikhethelo: Metara ea khafetsa, karolo e itokiselitseng oscilloscope
Sistimi ena ea liteko ea continuous-wave nuclear magnetic resonance (CW-NMR) e na le makenete e phahameng ea homogeneity le yuniti e kholo ea mochini.Makenete oa ka ho sa feleng o sebelisoa ho fana ka matla a khoheli a mantlha a phahamisitsoeng ke sebaka se feto-fetohang sa motlakase, se hlahisoang ke li-coil, ho lumella phetoho e ntle ho matla a khoheli kaofela le ho lefella ho fetoha ha maemo a matla a khoheli a bakoang ke ho fapana ha mocheso.
Hobane ho hlokahala feela hona joale magnetizing e nyane bakeng sa sebaka se batlang se le tlase sa motlakase, bothata ba ho futhumatsa sistimi bo fokotsehile.Ka hona, sistimi e ka sebetsoa khafetsa ka lihora tse 'maloa.Ke sesebelisoa se loketseng sa liteko bakeng sa lilaboratori tse tsoetseng pele tsa fisiks.
Teko
1. Ho shebella ketsahalo ea nuclear magnetic resonance (NMR) ea hydrogen nuclei ka metsing le ho bapisa tšusumetso ea li-ion tsa paramagnetic;
2. Ho lekanya liparamente tsa hydrogen nuclei le fluorine nuclei, tse kang spin magnetic ratio, Lande g factor, joalo-joalo.
