From this graph, it emerges that, the motorcycle and personal car is used more by men than women.
In fact, regarding the difficulties to collect data in Cotonou, because of reticence of the interviewees to respond to survey’s questionnaires, this study doesn’t cover all the aspects of the complex and large field of transportation.

Therefore, sludge stabilization, treatment and other harm-reduction necessary composting process to be effective, rational use [1].
The composting experiment, the temperature of the pile by a thermometer data recorded once every 1 hour to achieve, by obtaining a draw point temperature of the different values of the sample obtained, according to the change in temperature of compost node for data analysis process is divided into we will response phase is divided into four parts discussion: mesophilic stage; stable stage; thermophilic stage; cooling phase.

Energy consumption is the main source of greenhouse gases, so the calculation of CO2 emissions for energy consumption is the primary task of development of low carbon. as the center of China's political, cultural and education, in recent years, Beijing has achieved good results in terms of energy conservation and emissions reduction, but with the accelerating urbanization, rapid economic development, the environment problem is still very serious.
When calculating the amount of carbon dioxide produced by energy activity ,in this paper, the coal, coke, gasoline, kerosene, diesel oil, fuel oil, liquefied petroleum gas, natural gas and electricity 9 kinds of energy consumption data, because the absolute amount, need to rule out carbon dioxide produced by electric power outside of Beijing
Chart 1 Carbon emissions amounts and growth rate in Beijing Summary Using Beijing resident population data to calculate the absolute per capita carbon emissions , the results is per capita 8.58 tons on 2011, compare with the European and American countries per capita carbon emissions, per capita carbon emissions in Beijing is not high.

Lifting speed is equal to worm input speed divided by the worm gear reduction ratio then multiplied by the elevating screw pitch.
ADAMS is mainly used as the simulation software, its own does not have complex function of modeling.So the simulation model was established in the professional 3D modeling software Solid edge V20,save as Parasolid (*.X_T) format,Let the model into ADAMS by the Parasolid model data exchange interface,Model of Parasolid data exchange interface is provided by the ADAMA/View.

The data comparison results in Tab.1 shows that ,the simulation model can effectively simulate the magnetic field distribution of Helmholtz coils.
4 Experimental Research on Artificial Controllable Magnetic Field
According to the theoretic analysis, an experimental device is designed to produce artificial controllable weak-magnetic field.
The superposition of coil field and geomagnetic field can effectively reduce the total field intensity within the measurement area, which is equivalent to the reduction of geomagnetic horizontal component. 6 Conclusion Based on the analysis of the magnetic field of Helmholtz coil, an effective simulation model is introduced to investigate the its distribution.
An experimental device is designed using circular Helmholtz coils to produce artificial controllable weak-magnetic field, which reliability is proved by measured data.

Fatigue crack closure is the phenomenon which is widely considered to cause reduction in the fatigue crack growth driving force due to the premature contact of crack faces at positive load levels during cyclic loading.
A linear fit was applied to the data of the upper part of the curve.
Fig.3(b) shows the offset compliance curve replotted after the original compliance curve data are offset from the straight line from the linear fit.

Experimentals
Samples of the Hastelloy X material in 50mm×75mm×1.6mm size are heated at
1175°C for one hour in the vacuum oven for pre-stress reduction and then naturally cooled
to room temperature before the welding processes.
Each value of hardness is taken from the average of 5 data points.
Each data are taken from the average of three samples.

Results and Discussion
Table 2 shows the fore-shortening and dog-boning data obtained for each of the materials analysed.
The dogboning of these three materials (Tantalum, Steel and Cobalt Chrome) are also quite similar to each other, therefore it seems that the dog-boning is quite sensitive to a reduction in the elastic modulus.

Research on Characteristics of Sediment in Yichang-Wuhan Reach after Impoundment of the Three Gorges
Online since: September 2013
Authors: Xiao Qiang Liu, Hong Qian Zhang, Yan Hua Yang
On account of this, this article analyzes data about coming sediment of Yichang and Hankou Stations to support characteristics of new sediment of Yichang-Wuhan Reach after impoundment of the Three Gorges with Mann-Kendall nonparametric rank test method.
In Mann-Kendall test, time series data under null hypothesis (x1,…,xn ) are sample of n independent and random variables and distribution; alternative hypothesis is two-sided test and its distribution to all k, jn, and k≠j, xk and xj is different.
Sediment runoff of other years all decreases, of which reduction in the period of 2001-2008 is obvious.
