Analysis on interaction effect of terahertz radiation with living biology system

In the first place, the coherent collective vibration models of the living biological molecule system (e.g. DNA and protion) are analyzed in this paper. Then we have analyzed yet order-disordering variance due to resonance effect and the nonlinear behavior of terahertz radialion(THR)-biological system interaction. The analytic results show that the interaction between the living biological system and THR can produce resonance excitation effect, and so the system can be produced under further action of the laser. In addition, we have analyzed the nonlinear properties of the THR bio-molecule interaction and explained the mutagenesis effects of THR. The theoretic analysis is consistent with the results of THR biological test.
