In recent years, white light digital speckle method (PanYiShan etc) [1] used in geotechnical material deformation damage such as research has made great achievement.
Damage and material deformation often is indivisible, and by material deformation properties and condition, it can be divided into the elastic damage, the damage elastoplastic damage and creep damage (sometimes called viscoplasticity damage), fatigue damage and spelling damage, also called dynamic damage.
Experimental process Material of experiments is selected C30 concrete, pouring in block, within materials 44010050mm, a group of 50 with incision.

Due to the complexity of correlation and interference, electromagnetic compatibility problem that needs to solve number, later emc reinforcement not only consumes a lot of manpower and material resources and financial resources, affect the development progress and improve the cost, and the problem is difficult to fully and effectively solved, affect the quality and the system of the machine is the realization of the lighter index[2-3].
Mechanism and mathematical model 2.1 The working mechanism of electromagnetic compatibility system In the study of electromagnetic compatibility is in limited space, the limited time, under the condition of limited frequency resource, various kinds of electrical equipment (subsystem, system, generalized also includes organisms) can coexist is not a science ZhiYinQi relegation.
