No matter be high-field nuclear magnetic resonance equipment, or low-field nuclear magnetic resonance equipment, in nuclear magnetic resonance, RF magnetic field produces by radio-frequency coil. Radio-frequency coil has the effect that excites and receive NMR signal concurrently, under radio-frequency pulse effect, trigger sample in the H core generation magnetic resonance of CF, and after trigger impulse is closed, receive the NMR signal sensing. According to nuclear magnetic resonance principle, the RF magnetic field B1 that radio-frequency coil produces will meet following requirement: the RF magnetic field B1 (1) producing is orthogonal with the magnetostatic field B0 that magnet structure produces at target area needs; (2) RF magnetic field will be tried one's best evenly, to excite more sample to resonate; (3) the magnetic field intensity of RF magnetic field will be tried one's best greatly, makes the NMR signal receiving try one's best large.
Composite insulator is lightweight with it, and mechanical strength is high, and anti-pollution characteristic waits well premium properties, in ultra-high-tension power transmission line, is widely used.
