Computational results The acceleration data, vehicle parts position, member stresses and deformation results were used to pinpoint the actual cause of vehicle instability and subsequent rollover.
The reduction in strength associated with the drop in barrier width can usually be compensated by additional steel reinforcement bars inside the concrete.

Introduction Many structures may not be subjected to strong earthquake in the using period, many well-detailed structures possess significant reserve strength and capacity to dissipate energy, seismic load of structure is larger than designed seismic load, it is uneconomic to design complete elastic structure subjected to the stronger seismic load. [1]In advanced seismic design, structure subjected to strong seismic force are allowed to plastic and taken advantage of the fact that the structures possess ductility, dissipate energy and overstrength, design seismic load of fortification earthquake is permitted a reduction by seismic response modification factor (R) and seismic response is computed by elastic analysis, structure displacement of elastic analysis is magnified by displacement amplification factor (Cd) to estimate the max elsto-plastic displacement.
The enclosure area of capability curve and polygon line is assumed as A0, Ke is the initialization stiffness from the elastic data of capability curve; Ke （4）（5）（6） (3) Capability Spectrum Method.

Due to the effect of wool anti-felting is not satisfied by using protease alone, to enhance the reaction between protease and wool and improve wool anti-shrink effect, various oxidation pretreatment and reduction pretreatment are adopted [2].
Going through the data [3] and experiments, the main influence factors of oxidation pretreatment effect were found, which were pH value, concentration of hydrogen peroxide, processing temperature and time.

The specimens were prepared by casting into rod ingots and then drawn into wires with a diameter of 1mm and a sectional reduction of 90%.
All data procssing was conducted by the use of Origial 7.0.

Comparison of mineralogical composition of all samples before bioleaching and after bioleaching (data not shown) showed destruction and release of smectite, kaolinite, illite and goethite.
The results of the bioleaching serve as a starting point for improvement in microbial fermentation techniques by the application of chelators during speeding up of reduction and dissolution of iron from non-metallics.

The decoloriaztion activity was the higher while the glucose level was adjusted to 1% (data not shown).
Tomas, Aromatic amines from azo dye reduction: status review with emphasis on direct UV spectrophotometric detection in textile industry wastewaters.

In addition, reliable optical fiber components and instruments for the optical communication are easily available at this wavelength, resulting in significant cost reductions.
Transmitter Receiver Data Processing Laser : Er-doped fiber laser Wavelength : 1550nm Power : 13mW Linewidth : 17KHz Radiation : CW Aperture : f60mm Detector : InGaAs Bandwidth : 35MHz Dark current : 5nA Responsibility : 0.9A/W Signal processing : digital Sampling frequency : 100MHz A/D converter : 12Bit Technique : FFT Optical methods can be used to measure the velocity of a moving object by finding the Doppler frequency shift of a light beam reflected by the moving object.

(1) Where： --increment of volume reduction , γ- amplitudes of cycle shear strain , - residual volume strain, C1, C3, C2, C4 - constants, getting from cycle drainage tests.
Calculating parameters of soil layer are obtained from the engineering practical test of soft foundation, the lack data of test is derived from associated engineering .Detail physical and mechanical parameters are in Table 2.

(2) Figure 2 and Figure 3 show that, compared to 1949-2006 strong typhoon data for more than 50 years, number and frequency of strong typhoons nearly 5 years landing and affecting along the coast appear Increasing trends in china.
Study on the failure mechanism of coastal residential wind According to the damage investigations,most damage to houses was restricted to the envelope of building, in particular to roof sheathing.which indicate that an improvement in wind resistance of the building’s envelope will result in a significant reduction in overall economic losses.Failure mechanism of houses along the coast storms due to the Typhoon-prone area residential dwellings along the coast a large number of broad, each time the storms as a result of the economic problems, and also the essential problem facing social and political stability, so there is a need for low-rise buildings in storms damage mechanism of further scientific research.

Contaminant ions in the soil or aquifer generally have the following four forms of migration: ①advection is the phenomenon that contaminant ions move with pore water flowing. ②different flow rate leads to high concentration pollution zone geometric diffusion phenomenon is called dispersion. ③diffusion is that contaminant ions migrate from a region of high concentration to a lower concentration and finally tend to mean. ④solute can occur adsorption such as deceleration, detention and so on when through the porous medium, and it can produce chemical reactions leading to the reduction of pollutant concentration.
The calculated results provide basic data for correctly establishing transport model for pollutants in soil water environments, meanwhile it can supply theoretical basis for being able to predict potential hazards what the pollutant have done for underground environment and safe disposal.
