Therefore, the United Nations International Secretariat for Disaster Reduction supports multidisciplinary and cross-sectoral research in 2000,lays stress on the impact of natural disasters, human and environmental disasters to modern society[2].
Figure 2 Hazard Mechanism of Urban Disasters Emergency management policy Emergency management methods City sudden-onset natural disasters emergency management requires a large amount of information, which relates to a spatial distribution of geographic data, also includes the social-economic data.
And these data have characteristics of being changed with time changing.
Using GIS technology can build the framework of urban unexpected natural disaster emergency management system, can provide a good technical support platform for the realization of the system by using its powerful spatial data management and analysis capabilities, and can achieve seamless disaster information integration and efficient management.
In recent years, with advances in space technology, the ability of satellite remote sensing monitoring of surface features have been significantly improved, as well as resolution satellite data and observation frequency, real-time monitoring of disasters become possible.

Fu Yun, Ma Yonghuan think, low-carbon economy based on low energy consumption, low pollution, low emission and high efficiency, high efficiency, high energy (three high) as the basis, to low carbon development is the direction of development, energy saving and emission reduction are the way of development, developing methods to carbon neutral technology.
Therefore we should use objective data to support index, index data, or by the corresponding calculation can be obtained indirectly and indexdata sources should be reliable, should be scientific and reasonable evaluation standard (3) The integrity and hierarchy principle: index system as a whole, should more fully reflect the specific characteristics of the development of low carbon economy, that is, to reflect the social and cultural, economic industry, policy and law, science and technology development of the main characteristics of dynamic changes of specific indicators, various aspects of development trend, determined, must be based on certain logic rules level, reflecting the structure reasonable, (4) Dynamic and stability principle: the construction of low carbon economy is a dynamic process, which is mainly manifested in two aspects: one is the dynamic index setting, namely the index should be with the development of society, economy, science and technology and make appropriate
both static index and dynamic index of balance, not only reflect the status quo of the economic development, but also reflect the dynamic changes of the, (5) The principle of 3R: low carbon economy is focused by saving energy, improving energy efficiency, enhance the rate and reduce carbon emissions or zero emissions using material circulation, promote the coordinated development of man and nature, therefore, we must follow the principle of the 3R is a low carbon economy index system principles The evaluation index system of low carbon economy 科学性原则: 指标体系的构建必须具备一定的理论基础，要能够准确$客观地反映出低碳经济的实质和内涵# The scientific principle: the construction of index system must have a certain theoretical basis, to be able to accurately and objectively reflect the essence and connotation of low carbon economy Feasibility principle: constructing the index system of the main purpose is to review the development status of low carbon economy, therefore to be feasible, especially to be convenient for data
collection, data index is not easy to be collected should not be included in the system Representative principle: the selection of indicators can not be too much, more representative, can accurately reflect the characteristics of different economic development level evaluation , low-carbon aspects.
Because the index data selection method and different dimension, not a comprehensive evaluation on its directly, so it is necessary to carry on the standardization process: ,X is a reverse index, X'index is positive.

This reduction occurs because when HCl concentrations are extremely high, the acid easily becomes volatile, which is not conducive to the reaction in aqueous phase.
Although, the range analysis can easily determine the optimal value of different factors, it does not use all the data information.
Thus, ANOVA was utilized to assess the OAD results, which can reflect the volatility of data[13], which is dispersion of the data.
So, to verify whether the effect of individual factors on yield efficiency is statistically significant, an ANOVA was used to interpret the experimental data obtained from OAD optimization.

Additionally, function integration and reduction of number of parts can significantly reduce assembly costs.
Due to the fact, that material hardening strongly influences the prediction quality of die roll, extrapolation of yield data has to be validated.
Simulation data is evaluated exactly at the corner node, which is illustrated in Figure 7.
Due to the used ALE formulation and the specially developed remeshing technique, the material data can be extracted at the corner node over the complete simulation time without following a specific material point.
However, the material data is updated due to the convective transfer of state variables.

The neutron diffraction data were analyzed by the Rietveld method using Fullprof software in order to determine the position of the deuterium atoms.
According to X-ray data analysis, the hydrogenated TbNi0.4Co0.6 compound is single-phase but the initial TbNi0.4Co0.6 compound underwent a structural transformation during hydrogenation, turning into another structural type: TbNi0.4Co0.6 hydride has an orthorhombic structure CrB-type S.G.
The obtained data were used for refinement of the structural parameters and interatomic distances.
As it had been shown by neutron diffraction data deuterium atoms in TbNi0.4Co0.6 occupy 8f, 4c and 4b positions.
Those calorimetric data allow us to propose that hydrogen fills up interstitial site 4c first of all and then occupation of 8f site takes place.

General aviation market data show steady increase of sales and production[1].
This inherent variability drives up the cost of composite testing and tends to render smaller data sets than those produced for metallic materials.
In this data reduction method, the data from all environments, batches and panels are utilized together to generate statistical information about the corresponding test.
This approach utilizes essentially small data sets to generate test condition statistics, and simutaneously considers population variability and corresponding basis values to pool results together for a specific failure mode across all environments[7].

Introduction The design and manufacturing of dies and trial products, which require a long lead-time due to repeated trail-and-errors during the development of these products, holds the key to the reduction of the lead-time and cost [1].

Surface nodes temperature simulation(ap=0.005mm) is shown in Fig. 2,surface nodes temperature data is in Tab 1.
Tab 3 The surface node temperature of different wheel speeds vs(m/s) 20 26.38 32 T(℃) 225 240 250 2.2 Effect of Workpiece Speed on The Grinding Temperature If vapor cooling, ap=0.015mm, vs=26.38m/s is selected in simulation conditions, surface nodes temperature simulation data will be shown in Tab 2, corresponding to different workpiece surface speeds.
The heat source intensity increases with increment of workpiece speed and reduction of heat action time on workpiece. 2.3 Influence of Wheel Speed on The Temperature Field If vapor cooling, grinding depth ap=0.015mm, workpiece speed vw=1.5m/min is selected in simulation conditions, surface nodes temperature data responding to different wheel speed will be organized into Tab 3.
Simulation and test data show that grinding depth impacts more on grinding zone temperature, and the datas of experiment 1 and 2 show that in a large grinding feed conditions, the water vapor cooling can controll the surface temperature within 400 ℃, and compared with dry grinding, the cooling effect is obvious; The influence of workpiece speed on the grinding temperature is not clear, and in various combinations of the grinding parameters, the surface temperature may increase, reduce or substantially not change with the workpiece speed increasing; The comparison with different grinding depths shows that with grinding depth increment the temperature increases jumpily. 4 Conclusions (1)Simulation and experiment results show that with water vapor as coolant, the change of the moving speed (1m/min≤vw≤3m/min)has little effect on the cooling effect
Simulation datas show that: when 0.01mm＜ap≤0.02mm and 0.02mm＜ap≤0.025mm, the water vapor cooling can controll the grinding zone temperature ranging from 300 ℃ to 400 ℃or less, reduced by about 65%, 50% or more, especially compared with dry grinding
