Ithuluzi Lokuzwakala Kwe-Magnetic Yenuzi le-LADP-1 (NMR)

Okuqukethwe okuyinhloko kokuhlola
1. Yazi futhi uqonde isimiso kanye nesenzakalo se-nuclear magnetic resonance (NMR).
2, ingabona isignali ye-nuclear magnetic resonance engu-1H kanye no-19F, ukulinganiswa kwenani le-gN kanye nenani le-nuclear magnetic moment.
Amapharamitha obuchwepheshe ayinhloko
1, ubukhulu besiginali: 1H ≥ 100mV, isilinganiso sesiginali-kuya-kumsindo: 40dB, 19F ≥ 10mV, isilinganiso sesiginali-kuya-kumsindo: 26dB.
2, imvamisa yokunyakazisa: 18.5 MHz ~ 23 MHz ingalungiseka, kuye ngokuthi insimu kazibuthe iyasebenza yini.
3, isignali yensimu yokushanela: amandla ensimu yokushanela angu-0 ~ 200 mA angalungiseka.
4, isikhundla sokunyakaza kwe-probe: 0 ± 40 mm.
5, amasampula: amanzi afakwe i-copper sulfate noma i-ferric chloride, izinduku ze-polytetrafluoroethylene, njll., ngokulandelana.
6, i-magnet ehlala njalo: amandla ensimu angaba ngu-480mT, ukufana okuhlobene kwensimu yamagnetic kungcono kuno-10-5, igebe lensimu yamagnetic: 15mm.
7, kufaka phakathi imitha yemvamisa, umsebenzisi udinga ukuhlonyiswa nge-oscilloscope ephindwe kabili.
