Friction produces wear but wear affects the surface topography and by that the friction power itself.
A typical technical system with these properties are brake systems [Sev.95].
Fig.2: Patches on a brake pad These patches control and determine in a fundamental way the friction and wear properties of the brake system.
An example for an ancient brake material with such properties is wood (e.g. used to slow down windmills at forthcoming storms).
This suggest dynamical properties of friction and not only noise or malfunctions of the measurement chain. 4.

Modification of the ø26 mm round bars rolling technology with accelerated cooling, affect the reduction of average austenite diameter, which cause improving impact resistance of the final product.
Due to this, the correct strength and plastic properties of finished products cannot be assured.
Unification on the cross section and reduction of the austenite grain size should causes uniform mechanical parameters and increase impact resistance.
Production of the ø26 mm round bars in proposed technology, with one accelerated cooling section during rolling enables estimation of final product with slightly higher mechanical properties.

The Development of Rock Failure Electromagnetic Emission Monitoring System HUANG Song-ling1, ZHU Fu-rong2, ZHU Hong-xiu2, WEI Zheng1, WANG Shen1 1.State Key Lab of Power Systems Department of Electrical Engineering, Tsinghua University, Beijing 100084, China), 2.School of Mechanical Electronic & Information Engineering, China University of Mining & echnology(Beijing) Key words: rock failure electromagnetic emission; electromagnetic induction; signal-conditioning circuit; LabVIEW programming Abstract.
Several testing results have been achieved in rock failure experiments on marble that are carried out both by mechanical loading and expansion caused by chemical agents. 1.
In addition there are some other factors that may affect the result of rock failure experiment and must be considered carefully, such as the difference in composition and inhomogeneous distribution of composition even in the same kind of rock and different methods leading to fracture [1-3].
When a rock is loaded to failure by a mechanical device, it only takes a short period of time of several minutes with relatively strong EME.

The structural and optical properties of the ZnO films were studied by X-ray diffraction (XRD), UV-Vis-NIR spectroscopy, respectively.
The electrical properties of the ZnO thin films were characterised by dc 2 probing system and power supply (Advantest R6243).
It was found that the deposition speed affects the resultant properties of ZnO thin films.

The effects of hydroxymethylated alkali lignin participated in resin synthesis on properties of urea-formaldehyde resin were investigated to find the proper formaldehyde addition amount.
The proportion of lignin (on the base of urea amount) changed from 10% to 35%, and the properties of resin were determined and results were shown in Figure 1-3.
(4) The addition of lignin affected the properties of UF resin, the free formaldehyde content was the lowest when lignin amount was 30%, and the binding strength was 3.41Mpa at this condition, which could achieve the level of national standards.

In the use of renewable energy,when systems and equipmen are in normal operation conditions, HDR provides a continuous supply of energy that will not be affected by natural factors like season, climate, day and night and other natural factors.
In terms of the current study conditions, to mention the location of the Iwai, we should take two important factors into consideration: geothermal gradient and heat flow values of rock.
Besides, integrated the earth's physical properties, we should choose the plate collision zone, including the mainland and the mainland, the mainland and the sea collision zone.
Furthermore, from the perspective physical properties of the rock, we should selecte density, high thermal conductivity and generate late rock.
In addition, developers should pay attention to the parameters of the HDR permeability, porosity, cracks, geothermal gradient, to determine accurately these factors critical evaluation of the development costs.
