Much of the pioneering work using the DEM simulation to simulate the behavior of granular materials was performed by Cundall and Strack[18, 19].
The DEM simulation has been extensively developed over the years to evaluate the dissipative properties of granular materials.

The synthesized Ca2.6Bi0.4Co4O9 ceramic materials have potential application for high-temperature thermoelectric energy conversion.
Developments of thermoelectric materials which convert heat into electrical energy are expected for the efficient use of energy.
The thermoelectric materials should be chemically and thermally stable to utilize waste heats, since they are supposed to work under conditions of high temperature and corrosive atmospheres [1-3].

There are many factors affecting concrete resistivity, such as compositions of raw materials, mix proportions and service condition, etc; but the most direct and effective method is adjusting the compositions of raw materials.
Materials and experimental set-up In this experiment, ordinary Portland cement (OPC), fly ash (FA classⅡ), slag (SL), aggregates (sand 0-5 mm, coarse 5-25 mm) and naphthalene super-plasticizer (NS) were used as concrete materials.
Fig.4 The effect of two mixed ratio on concrete resistivity Fig.5 The effect of two mixed content on concrete resistivity Discussions The materials based on cement, such as cement mortar and concrete, are nearly all ionic conductor materials, the current carrier during electric current transporting in concrete is ion [11], so the compaction rate and ionic concentration are the main influencing reasons for the resisitivity of such materials.

Introduction
A series of conductive polymer materials have been developed, since MacDiarmid and Shirakawa made conductive polyacetylene by iodine-doped [1].
In this study, we chose aniline, o-Phenylenediamine and cotton plain weave fabric as the primary materials.
Experimental Experimental Materials White plain weave fabric of cotton (120g·m-2) with the count of 19.4 Tex, both the warp and weft of the cloth density are 268 per 10cm.
