Electromagnetism a powerful person is clean to medium degree have higher demand, the medium that contains grain condition cannot applicable, if belong to foreign matter beard first filter goes. Additional, ropy shape medium cannot applicable, and, the medium viscosity limits with specific applicable product is opposite narrower.
(5) model is diversiform, use is extensive
Although electromagnetism a powerful person has congenital inadequacy, advantage still very outstanding, become varied product with respect to the design so, satisfy all sorts of different requirement, use is very extensive. The progress of technology of electromagnetism a powerful person also is around move how to overcome congenital inadequacy, how produce inherent advantage better and spread out.
