Currently, test materials used in the heavy metal removal studies by adding chemical drugs are mainly dehydrated dry sludge and studies on concentrated sludge with rich moisture contents or sludge from secondary sedimentation tanks are very few.
Materials and Methods 2.1 Materials The sludge used in the test is from the secondary sedimentation tank of some sewage plants in Guilin and is with quality concentration of around 15-20g/L.

Often, the intelligent materials used in civil engineering for intelligent control are Electrorheological (ER) fluid and Magnetorheological (MR) fluid, so the most often used intelligent control devices are ER damper and MR damper.
The National Museum of Emerging Science and Innovation in Tokyo, called Miraikan, installed two 30-tons MR dampers on third and fifth floor each, which took a good role in anti-vibration caused by earthquake or wind.

AE is defined as “the class of phenomena whereby transient elastic waves are generated by the rapid release of energy from localized sources within a material, or the transient waves so generated” (ASTM E1316) [3].
The results show that AE cusp catastrophe model can estimate the time at which state might change from elastic deformation to yield deformation of 16Mn steel in tensile test, but it is found that some catastrophe time estimated with AE cusp catastrophe model is not satisfied because that the state of 16Mn steel plate specimen didn’t change from elastic deformation to yield deformation, the reasons might be the experiment data decentralization that was caused by materials properties, test equipment error, operating personnel error and so on, or the background signals effect.

The flexible joints can be driven by motor, fluid and functional materials etc. and servo motor drive is the most common form[1-4].
The joints driven by functional materials have flexible response to micro-control and they can mimic human facial expressions.
Conducting polymer, ion exchange membrane and metallic composite etc. have been used as the functional materials so far[5].

While due to the large amounts of intrinsic defects would expose relatively serious self-compensation effect on p-type materials, the preparation of p-type ZnO and p-n homo-junction is extraordinarily difficult.
Al is prone to realize doping in ZnO and easy to get as the raw materials of Al is abundant [6].
