Description
Technical field
The present invention relates to a kind of application method of novel magnetic experimental provision, specifically a kind of adjustable steady magnetic field experiment
The application method of device.
Background technology
Magnetic field is a kind of special material that can not be seen or touch.Magnetic field is not and the magnetic field by atom or molecular composition
It is objective reality.Steady magnetic field（Static magnetic fields, SMFs）：It is that magnitude of field intensity is more stable constant
Magnetic field, due to its invariable characteristic can as biomedicine point of penetration.Conventional research illustrates stationary magnetic field pair
Different cell has different effects, and everything both depends on the size of stationary magnetic field and the type of target cell also has magnetic
Action time of field etc..In clinical medicine, stationary magnetic field can control the growth of tumour cell and promote bone marrow cell growth.
Influence of the magnetic environment to cell is different, but it is also due to externally-applied magnetic field and institute's band inside cell itself to investigate its essence
There occurs certain reaction between some magnetic field so as to cause magnetic field can be to cell change.Effect of the steady magnetic field to cell be
It is diversified, the magnetic field factor such as magnetic field intensity, magnetic field processing time be influence cell, the biological effect such as bacterium it is main because
Element, the magnetic field in the experiment of the above are required for a corresponding magnetic field loading device to complete, the magnetic required for each experiment
Different corresponding different most of the devices, research of the current magnetostatic field to organism and cell of field intensity are control magnetic field intensities
To complete control experiment.
So, it would be desirable to the steady magnetic field experimental provision and its application method of a controlling magnetic field intensity are designed, to expire
The requirement of the various experiments for needing steady magnetic field of foot.
The content of the invention
To solve the above problems, the technical scheme is that：A kind of application method of adjustable steady magnetic field experimental provision,
Mainly it is made up of base and operating desk two parts.It is characterized in that：The base is a horizontal positioned cuboid, rectangular
