As same as, to the rock mass, which with well constitutive property and higher strength, which can be treated as the mixture composed of mineral crystal particles and cement material among crystal particles.
Conclusion 1) The first time of impact force to the monitor wall is same basically, but there is some difference since the difference of the bond strength. 2) The starting time of continue impacting to the monitor wall is delayed with the increating of the bond strength, but which is bring forward when the bond strength over 103kPa. 3) The max impact force increases with the bond strength increasing.The landslip-collapse soil impact to the monitor wall as a whole sliding block when the bond strength is higher and the impact force add up to the max instantly; The landslip-collapse soil impact to the monitor wall as a viscous fluid when the bond strength is smaller Acknowledgements This article was financially supported by the National Natural Science Funds (No.40830742, No.50979103) Reference [1].

Introduction
Activated carbon, with the features of well-developed micropores, high specific surface area, strong adsorption capacity, strong mechanical strength, and easy regeneration, is a good adsorption material widely used in the fields of chemical, environmental, food and pharmaceutical, catalyst supports and electrode materials.
Experimental Work Raw Materials and Instruments.
When the raw material is treated, volatile component escapes, leaving pores in the raw material.

The material is pumped into treatment chamber.
Bipolar squared-wave pulses shows stronger deadly ability to microbe and it can reduce the sediment and electrolysis of materials.
Generally, the available insulation materials are polysulfone resins, polytetrafluoroethylene and polyisobutylene acid resin.
Stainless steel is usually used as electrode materials.

Materials used in them, especially Ni-base superalloys, are so expensive items that they can be a substantial part of an operating and a maintenance budget [1-9].
The other is from such findings that the FCPRs are generally insensitive to the yield strength of materials, rather more sensitive to elastic modulus [10-13]: in the other words, the FCGR of the virgin IN939 must be comparable to that of the virgin IN738, because of comparable elastic modulus between the both materials.

At the beginning of deep drawing process of box shaped part, the redundant material is in maximum tangential compressive stress state when it is forced to convergence inwardly, then the redundant material turns into maximum radial tensile stress state due to the tension from material at the bottom of the box shaped part.
The blank was an normal deep-drawing steel sheet, 08, whose behavior was modeled by Material Type 36[9].
The property data of these two materials is tabulated in Table 1.
