Another possibility is that the areas with the highest risk of debris flows due to steep slope, low vegetation cover, and other factors may have lost all or most of their erodible material in previous debris flows.
Whether erosion and debris flows actually occurs depends on whether erodible material, and whether other factors such as slope allow the falling water to transport this material.

The piezo-spectroscopic effect for polycrystalline materials can be expressed by the following equation: � � = � < � ij >
For randomly oriented polycrystalline materials, an average equi-biaxial or hydrostatic stress can be expressed as [8,9]: < � ij >= � � / a �
Given these complex and peculiar phase characteristics, phase metastability is the most relevant problem in zirconia materials.
This well explains the superior fracture resistance of bones as compared to synthetic hydroxyapatite materials produced by conventional sintering processes.
The quantitative knowledge of microscopic stress fields may enable replacing the empirical optimization of biomaterials processing and employment with more rational procedures, thus greatly enhancing the speed for the development of new materials, including their better utilization, in this important field of materials science.

Vortex reactor The characteristics of vortex reactor The core of micro-eddy current coagulation is vortex reactor, Vortex reactor is the porous hollow sphere that made of ABS plastic-based material, Inside and outside the sphere surface made into rough surface, surface has small holes, aperture and the opening rate in accordance with the determination of water treatment.
It has the following characteristics[1] : (1) the flow velocity and orientation changes in through-hole water flow, in addition, the friction of both inside and outside the wall resistance, Have a micro-flow vortex flow;(2) Easy construction, Without the installation of fixed, No direction requested, it can be put into the pool directly;(3) Materials have good strength, not toxic, Corrosion-resistant, Anti-aging, Service life of several decades;(4) Simple structure, Management convenience, easy operation and maintenance, Up to the water in the stream will float and rotate, can not easily be blocked floating
* project (50868005) supported by National Natural Science Foundation of China Figure1 the vortex reactor coagulation schematic diagram Principle of eddy current reactor[2,3] Attaining the better coagulation-flocculation effect, the micro-whirling reactor can create the better hydraulic condition with respond to each kind of intrinsic hydraulic factors.

Introduction High temperature applications require new categories of structural materials with high toughness and hot corrosion resistance in order to increase the operating temperatures.
Since the last ten years, niobium alloys are considered as a real potential material allowing the use of the refractory alloys in high temperature applications.
The alloying additions of the niobium solid solution decreases the solubility of tin (3.7 at.% ) in bcc niobium as compared to 6at% in pure Nb at 1200oC according to the Nb-Sn binary [[] C.Toffolon, C.Servant, J.C.Gachon and B.Sundam, Reassessment of the Nb-Sn system, Journal of phase equilibria, Vol.23 N°2, 134-139, 2002. ].
They would like also to thank the common service of microscopy and microanalyses (SCMEM) of the Faculty of Sciences and Techniques of Nancy (France) for its help for microscopic observations.

The reasons influencing the factor are mainly itself material limits and temperature shock times too frequently on catalyst caused by the frequent start.
