This study is analyzed by numerical analysis using finite element method program of Plaxis-3D Tunnel at Kaohsiung Science Park in Taiwan.
These parameters include soil range of ground improvement, soil material parameters, PJC materials parameters, and gap contraction ratio CR (%).
Mohr-Coulomb model are adopted for the soil material.
Those material parameters in numerical analysis are shown in Table 3.

The most extensively applied materials are cast ceramic and zirconia ceramic.
Since most base materials in a dental clinic are only 0.5~0.8 mm thick and are easily influenced by the dental crown's core materials, the materials express an overall color deviation from the crown.

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].

New scaling for ac properties of percolating composite materials.

Introduction For brittle rock materials, the damage course of rock is related to inner crack propagation.
For elastic-brittle materials such as granite, during the course of compression, it only produces elastic deformation.
Most materials release acoustic when deformation and fracture.
If the load is increased flatly, materials go through such stages as elastic, injury, damage and buckling in turn.
