Abstract: | The polarization anti absorption principle of corona virus in the electric field is presented. It is ex-pressed by the mathematic differential equation based on the physical model. According to the parameters of the dipole moment of virus, the electric field force exerted by the external electric field can be calculated. Accord-ing to the parameters of size, mass and elastic modular, etc. , the moment of inertia of virus can be calculated.According to the viscosity of tissues, the resistant force when virus rotates can be calculated. According to the balance condition of relaxation polarization, when the drive force equals to the resistant force, the rotating or swaying frequency of virus can be calculated. According to the heat producing condition such as friction, the temperature rising of virus can be calculated. When the temperature exceeds a certain threshold, virus would be inactivated. Through the calculation, it is found that the movement type of the virus depends on the intensity and frequency of the external electric field, which are the effects of "intensity widows" and "frequency win-dows". It also gives approximate calculation of the temperature rising of the virus according to this model. The vitro experiment confirms the reasonability of this model. The electric fields of different densities of a certain frequency are applied to the solution of avian infectious bronchitis virus. Through the toxicity experiment of the SPF chicken embryo, it is found that the toxicity is decreased exceedingly with a certain intensity of the applied voltage. EID50 decreases from 6. 70/0. 2 mL to 2. 66/0. 2 mL. It is proved that the avian infectious bronchitis virus can be inactivated with a certain low frequency and low-density electric field. |
