The effective factors such as materials modulus, the density as well as the assembling all contribute to the analyzed results.
Table 2 The relationship between basic frequency and material elastic modulus Material elastic modulus (GPa) 25 35 45 55 65 75 basic frequency（HZ） 1721 1744 1760 1782 1801 1816 Table 3 Relationship between basic frequency and materials density materials density（kg/m3） 1160 1360 1560 1760 1960 2160 basic frequency（HZ） 1774 1768 1760 1751 1743 1732 It is seen that the honeycomb panel’s basic frequency will decrease with the materials density increasing, and it will increase with the material elastic modulus increasing .So we can choose the right material according to the requirements of the task timely.

Introduction High dielectric constant materials have been playing significant role in numerous technological applications, such as capacitors and memory devices [1].
It seems that the CDC has a tight link with the conductivity of the materials.
As a well investigated material, SrTiO3 (STO) exhibits interesting quantum paraelectric property.
Referring to the particular electronic structure of SrRuO3, our motivation is simple and direct: an appropriate doping of Ru into STO seems to possible to modulate the conductivity of STO in order to investigate the relationship between the dielectric relaxation and the materials conductivity, including the possible CDC effect.
As the above said, the OVs could be easily formed in grains for perovskite structure materials containing titanate due to the oxygen deficiency during the ceramic high temperature sinter process in air [16-17].
