EPR-60
ʻO ka electron paramagnetic resonance (EPR) kahi ʻano ʻenehana resonance magnetic i hoʻokumu ʻia mai ka manawa magnetic o nā electrons i hoʻopaʻa ʻole ʻia. Hiki ke hoʻohana i ka qualitatively a me ka quantitatively ike i ka unpaired electrons i loko o nā'ātoma a i ole mole o nā mea, a e makaikai ia lakou. Nā hiʻohiʻona o ke kaiapuni a puni. No nā radical manuahi, ʻaʻohe hopena o ka manawa magnetic orbital, a ʻo ka hapa nui o ka nui o ka manawa magnetic (ma luna o 99%) e hāʻawi i ka wili electron, no laila ua kapa ʻia ka electron paramagnetic resonance "electron spin resonance" (ESR).
Ua ʻike mua ʻia ka resonance electron paramagnetic e ka physicist Soviet kahiko ʻo E·K·Zavois ma 1944 mai MnCl2, CuCl2 a me nā paʻakai paramagnetic ʻē aʻe. Ua hoʻohana mua nā physicists i kēia ʻano hana e aʻo ai i ke ʻano uila, ka ʻano aniani, ka manawa dipole, a me ke ʻano molekala o kekahi mau ʻātoma paʻakikī. Ma muli o nā hopena o nā ana ʻana o ka electron paramagnetic resonance, ua wehewehe ka poʻe chemists i nā paʻa kemika a me nā puʻupuʻu electron density i loko o nā pūhui organik paʻakikī, a me nā pilikia he nui e pili ana i ka mīkini pane. ʻAmelika B. Commoner et al. ua hoʻokomo i ka ʻenehana resonance electron paramagnetic i ke kahua o ka biology no ka manawa mua ma 1954. Ua ʻike lākou i ke ola ʻana o nā radical manuahi i kekahi mau mea kanu a me nā holoholona. Mai ka 1960s, ma muli o ka hoʻomau mau ʻana o nā mea kani a me ka hoʻomau mau ʻana o ka ʻenehana, ua hoʻohana ʻia ka ʻenehana resonance electron paramagnetic i ka physics, semiconductors, organic chemistry, complex chemistry, radiation chemistry, chemical engineering, marine chemistry, catalysts, biology, a biology. Ua hoʻohana nui ʻia ma nā ʻano he nui e like me ke kemika, lāʻau lapaʻau, ʻepekema kaiapuni, a me ka ʻimi ʻana i ka honua.
Hoʻohana nui ʻia ia no ka ʻike ʻana i nā radical manuahi a me nā ion metala paramagnetic a me kā lākou pūhui e loaʻa ai ka ʻike a me ka ʻike. No ka laʻana: ke ana ʻana i ka maʻalahi o nā paramagnets, ke aʻo ʻana i nā kiʻi ʻoniʻoni ʻoniʻoni magnetic, ke alakaʻi ʻana i nā electrons i nā metala a i ʻole semiconductor, kekahi mau hemahema lattice kūloko i nā mea paʻa, ka pōʻino o ka radiation a me ka hoʻololi ʻana o ka radiation, ka radiation ultraviolet short-lived organic free radicals Ke ʻano o ka electrochemical. ke kaʻina hana, ke ʻano o nā radical manuahi i ka corrosion, ke ʻano o nā metala paʻakikī i ka hoʻohui ʻana i ka kemika, ka mana saturation point o ka lauoho kanaka nā radical manuahi, ka pilina ma waena o nā radical manuahi i loko. nā ʻiʻo a me nā maʻi, a me ke ʻano o ka hoʻohaumia ʻana i ke kaiapuni.
1, Mākēneki kahua laulā: 0 ~ 7000Gauss mau adjustable
2、Pole poʻo spacing:60mm
3、ʻano hoʻoluʻu: hoʻoluʻu wai
4、Kapaona holoʻokoʻa: <500kg
Hiki ke hoʻopilikino ʻia e like me nā pono o ka mea kūʻai aku
