These materials have also been reported to undergo certain changes in their physical properties when exposed to gamma radiation [6].
Compton scattering occurs at intermediate energies and with materials of low atomic number while and pair production takes place at high energies.
Thus hydrogenous materials have a higher probability of Compton scattering than a non hydrogenous material of equal mass [9].

Established dynamic model of panel with uncertain parameters containing active constraint structure For panels we used composite materials which are orthogonal anisotropy.
Substitute eq. (4) into eq. (3) : Dynamic analysis of panel with uncertain parameters based on active control method for suppression by piezoelectric materials Because of the uncertainty of parameters and structure of system, mass, damping and stiffness matrices of vibration equation are uncertain.

Especially in recent years, with the industrial development and more and more serious environmental degradation and energy shortages, the development of new energy and new energy materials has been major issue that must be solved in the 21st [1].
The vibration and the rotation elevate the wet material temperature to achieve the purpose of heating wet material.

Where, is the initial elastic stiffness of materials ; d is damage factor , ; material is not damaged , d=0 , material is full damaged, d=1[2-4]。
The surplus elasticity produced by damaged materials and that produced by nondestructive materials are the same in the form.
Due to softening and stiffness degradation of concrete materials will make easily the calculation convergence.

It can be seen from result that development and deformation of borehole elastic area mainly affected by ambiequal ground stress value, difference of ambiequal ground stress and rock material properties so on.
But for the nonlinear rock medium, material plastic deformation is a key mechanics parameter closely related to distribution patterns of borehole stress.
