LADP-1A Pūnaehana Hoʻokolohua o CW NMR - Kūlana Kiʻekiʻe
wehewehe
Mahele koho: ʻO ka mika pinepine, ʻāpana oscilloscope hoʻomākaukau ponoʻī
ʻO kēia ʻōnaehana hoʻokolohua o ka hoʻomau nuklea nuklea resonance (CW-NMR) i loaʻa i kahi magnet homogeneity kiʻekiʻe a me kahi mīkini nui.Hoʻohana ʻia kahi magnet paʻa no ka hāʻawi ʻana i kahi māla magnetic mua i hoʻopaʻa ʻia e kahi māla electromagnetic hiki ke hoʻololi ʻia, i hana ʻia e nā coils ʻelua, e ʻae i ka hoʻoponopono maikaʻi ʻana i ka huina magnetic a e hoʻopaʻi i ka fluctuations o ke kahua magnetic i kumu ʻia e nā ʻano wela.
No ka mea pono wale nō ka mana magnetizing liʻiliʻi no ke kahua electromagnetic haʻahaʻa, hoʻemi ʻia ka pilikia wela o ka ʻōnaehana.No laila, hiki ke hoʻohana mau ʻia ka ʻōnaehana no kekahi mau hola.He mea hana hoʻokolohua maikaʻi loa ia no nā laboratories physics kiʻekiʻe.
Hoao
1. No ka nānā 'ana i ka nuclear magnetic resonance (NMR) hanana o ka hydrogen nuclei i loko o ka wai a ho'ohālikelike i ka mana o nā ion paramagnetic;
2. No ke ana i na palena o ka hydrogen nuclei a me ka fluorine nuclei, e like me ka spin magnetic ratio, Lande g factor, etc.
