Technical field
The utility model belongs to Detection Techniques equipment field, and in particular to a kind of nuclear magnetic resonance efficient nano ceramics transmitting day
Line.
Background technique
For nuclear magnetic resonance mainly as caused by nuclear spin motion, nuclear magnetic resonance is the atomic nucleus that magnetic moment is not zero,
Zeeman splitting, the physical process of the radio-frequency radiation of RESONANCE ABSORPTION certain frequency, core occur for the energy level that spins under external magnetic field
Magnetic resonance spectroscopy is a branch of spectroscopy, and for resonant frequency in radio-frequency range, corresponding transition is nuclear spin in core plug
Transition on graceful energy level；Nuclear magnetic resonance application: Magnetic resonance imaging (MRI), which checks, has become a kind of common image check side
Formula, Magnetic resonance imaging will not have an impact to human health as a kind of novel Imaging Techniques, detection water source, mineral deposit,
, there is similar remote sensing type metal detector currently on the market in archaeological excavation etc., but the transmission power of existing equipment compared with
It is small, it is too only several milliamperes small by the electric current of coil the problems such as low efficiency, very weak signal can only be issued, when continuing to increase hair
When ray loop current, the air among insulation water pipe and skeleton as coil rack can be punctured by the electromagnetic signal on coil；
(positive and negative charge carried in normal condition lower insulator molecule attracts each other balance, then high temperature and pressure or high-intensity magnetic field feelings
Positive and negative charge inside condition lower insulator will free one's minds as free charge, and insulator breakdown becomes conductor) such case
The signal that lower instrument transmitting coil issues is equal to two that the signal ledger line ring framework that instrument itself issues generates false letters
It number sends out together, so emission effciency can not be increased by being limited by material, the substance of mistake can be detected, when coil is made
When big, the central magnetic field intensity of coil can be very weak, and therefore, the utility model is insufficient in view of the above technology and it is total to provide a kind of nuclear-magnetism
Shake efficient nano ceramics transmitting antenna.
Utility model content
The purpose of this utility model be in order to make up the deficiency in background technique, and provide a kind of structure it is simple, it is small in size,
The big strong nuclear magnetic resonance efficient nano ceramics transmitting antenna of transmission power.
