The results of creep curves agree well with the
traditional constant load creep test data.
Those creep curves have a good agreement with traditional constant load creep test data.
Similarly, these data, or data generated at constant machine displacement rate, are used to generate secant module for pseudo-elastic design analysis.
In fact, creep curves generated from SRT test show a good agreement with actual constant load data.
Fig. 4 shows that creep curves generated with SRT agree with experimentally determined data very well.

The soil pressure properties and size have a very close relationship with the sheet pile’s displacement,some experiment datas [6] show that in fact after the sheet pile with a single anchor active earth pressure distribution is like “R” form.
In order to get more economical results, Engineering designers usually make the maximum bending moment in mid-span by multiplying a reduction factor.
The option of the reduction factor is also a complex problem [6][7].
According to the criterion [5], the recommended reduction factor’s select range is 0.7 ~ 0.8.
Considering slant at security, the paper’s choice for the reduction factor is 0.8.

Because of ISO standard data is based on the paper without OBA, it makes a great diversity of result in color reproduction, and causes the printing production not to meet international standards.
In accordance with ISO 13655-2000, basing on M2 state will rectify these errors. [2] [3] for different requirements, the ISO whiteness data, chroma data and spectral reflectance date will be got for different state like M0 or M2.
Under the inflexion point, the improved data represent more stable.
Outside of the inflexion point, the improved data appeared larger fluctuations.
In order to compare the affection of different amount of OBA on the color reduction, the experiments get five groups chromatic values.

Crystallization with low cooling rate leads to the reduction of the amount of carbon into g-phase.
Table 1 contains the statistical data of analysis including a scatter between minimum and maximum diameters of particles and also the calculated volume fraction of graphite.
On the basis of the obtained data average CTE of alloys in the set temperature intervals have been calculated: 20-100 °C; 20-200 °C; 20-300 °C.

For enhancing national energy security and combating global climate change, Chinese government regards Energy Saving and Emissions Reduction (ESER) as the utmost important tasks which should to be realized urgently.
According to BP statics data reported, the proved natural gas at the end of 2010 in China is 99.2 trillion m3 with the reserve-production (R/P) ratio is 29 [14].
Thereby adopting hydrogen as the alternative hardly realize energy saving and emissions reduction indeed.
Albeit the oxidation of hydrogen and oxygen won’t generate any emission materials, the actual combustion process of hydrogen and air will generate NOx due to the higher temperature, how to deal with NOx in essence then to realize emissions reduction completely is another task for the application in vehicles.
Hydrogen, which has huge production potential in the current China, can practically widely employed as the fuel for vehicles to realize energy saving and emissions reduction on transportation sector.

Currently, there are two potential routes to improve vehicle efficiency, i.e. powertrain optimization and mass reduction.
Through using lightweight materials, it has been shown that a 5-7% fuel saving can be achieved with a 10% reduction in vehicle weight [1,2].
Many developments in vehicle weight reduction focus on utilizing aluminium alloys to replace steels in vehicle body structures.
Major and minor strain data was exported from sections defined perpendicular to the necking on the specimens, and input into a developed fitting program such that the limit strains could be extracted [10].
