The relationships between ζmin, ωmin, α and β are: ζmin=(αβ)1/2 （2） ωmin=(α/β)1/2 （3） The scope of the critical damping ratio ζ is generally 2%- 5% for rock materials; the maximum center frequency ω is usually 3 times of the minimum frequency.

Treatment Investigation on Retting Hemp Waste Water with the Synergy of Activated Carbon and Microwave Rong Yang1, a, Quanli Feng1, b, Yu Jia1, c and Chunmei Shi1, d 1 Kunming University of Science and Technology, Kunming 650500, China aynkmyr@126.com, bqlfeng0871@sina.com, cjiayu@163.com, dshicm@163.com Keywords: activated carbon; microwave; retting hemp waste water Abstract.
Treatment of retting hemp waste water was made by the synergy of activated carbon and microwave in this experimental investigation, and the four factors that influenced the experimental results were considered in which there were respectively the material ratio of activated carbon dosage and retting hemp waste water volume, microwave radiation power, microwave radiation time and the initial pH value of retting hemp waste water.
The experimental results showed that, while the material ratio was 7:50 (i.e., the quality of activated carbon was 7g as the volume of retting hemp waste water was 50mL), the microwave radiation power and the microwave irradiation time were respectively 320W and 13min, and the initial pH value of retting hemp waste water was just 2, the treatment effect of retting hemp waste water was best in this experimental investigation.

Materials and Methods Three-dimensional (3D) model of a left maxillary posterior bone section was reconstructed based on CT image datasets by using Interactive Medical Image Control System software.
The material properties of the models were assumed to be homogeneous, isotropic and linearly elastic based on the previous studies [15, 16, 17].
