The higher material aggregation state of middle energy, particle therein have higher activity.In addition, interaction process between particles
In, common gases have completely different property with plasma.Interaction in common gases between particle is mainly phase
Collision between mutually, it is the effect of short distance Newton force, its useful effect radius is much smaller than particle mean free path, when most
In, particle is all linear uniform motion, and when it meets another particle, velocity magnitude and direction are believed that and instantaneously occurred
Mutation, therefore the movement locus of particle is the broken line being linked to be by straight-line segment.And plasma is between a large amount of charged particles
Interaction, the i.e. effect of long-range Coulomb force, the collective interaction between multiple charged particles will be overwhelmed between two particles
Collision, the deflection of charged particle wide-angle is that multiple small angle deflection accumulation forms, so the movement locus of charged particle
It is not simple broken line, but the small setback constantly occurred and gradually forms the curve to turn round greatly.And common gases particle it
Between collision be usually elastic collision, and the collision in plasma between particle also has in addition to elastic collision and non-resilient touched
Hit, and be largely inelastic collision.During charging particle movement in plasma, positive charge or negative electrical charge can be caused local
Concentrate, produce electric field；Electric charge directed movement causes electric current, produces magnetic field.Electric field and magnetic field can influence the fortune of other charged particles
It is dynamic, and along with extremely strong heat radiation and heat transfer；Plasma can make circumnutation under magnetically confined effect.
It is this in the presence of electric field and magnetic field, the effect caused by various particle interactions in plasma for
Solve the tool of many problems in industrial production to be of great significance, and the research for plasma has turned into electrician and developed
A frontier.By continuous research and development, people the application field of plasma constantly obtain new breakthrough and
Achievement so that plasma technique is widely used among actual industrial production.By plasma application in power field,
The thermal efficiency of unit can be improved, is reduced environmental pollution, slows down energy shortage problem to a certain extent；In mechanical industry,
Using plasmatorch cutting metal, processing surface, welded and built-up welding, it is not only easy to operate, the matter of product can also be improved
Amount；In chemical industry, using plasma synthesis acetylene, ammonia and organo-silicon compound etc., production efficiency can be improved, is improved
Properties of product；In the semiconductor industry, compared with conventional method, using plasma technology has quick, clean, productivity ratio height
And precision it is high the advantages that；In metallurgical industry, it can save the energy using plasma technology, reduce cost, increase economic efficiency.
Especially for plasma stream caused by being ionized as flowing gas, at material surface processing, medical science, weaving, discarded object
Reason etc. has huge application potential and more vast potential for future development.
However, the Production conditions of plasma stream are very harsh, according to gas discharge theorem, under atmospheric pressure environment, very
Hardly possible forms the plasma jet for meeting commercial Application length.Extract system is mainly aided in come shape by vacuum tank both at home and abroad at present
Into low air pressure condition, gas discharge is internally formed in vacuum tank, improves jet length and jet density, and vacuum equipment cost
Height, it can not move, and processed material needs to be moved in vacuum tank, part, which handles material, can influence system pumping, Wu Fa
Handling process is completed in vacuum tank.
