The overall design and programme design on the drive axle assembly is finished; the basic structure of the double reduction final drive and the middle tandem axle is ensured which refers to the structure of the reference model CA1092; The basic components on the drive axle assembly are designed.
The bottom-up assembly design from the parts begin to design, design for assembly in part based on the design data, so it can make full use of previously existing, make the design work started from a higher level, thus effectively avoid repeated design, shorten the design cycle.
Rendering results as below: Assembly process This design topic is the three-dimensional design vehicle drive axle double reduction final drive, the main part of the main two-stage reducer, differential, axle and axle housing.

A coarse grained Zr-Hf alloy has been subjected to one rolling pass with different thickness reductions ranging from 10% to 80%.
Texture data must be interpreted with caution since, due to the large grain size of the starting microstructure, the number of grains measured may not be enough to have a good statistics.
First, when applying reductions equal to 50% or smaller, significant twinning occurs.

Figure 2 Carbon price in the seven pilots 2.2 Achievements According to the current data, the ETS pilots go well,and have brought remarkable achievements.
Second, the consciousness of carbon reduction of enterprises has enhanced, many professional organizations are established for carbon asset management.
(3)Statistical accounting of carbon emissions data base is incomplete.
Before the carbon emissions trading pilot program, there are no corporate-level statistics on greenhouse gas emissions system.Therefore, in the beginning, the pilot were facing difficulties of data deficiency .Most pilots collect data form the historical emissions data, but these retrospective data is low-quality, there may be some bias in the pilot policy which was made based on these historical carbon emissions data.Such as the total carbon emissions may be set too high, the reference value of carbon emissions may be unreasonable designed.
Power generation enterprises may be unable to achieve carbon reduction.And it can’t promote the power consumer to reduce emissions through the price mechanism.

cm -1 (Raman shift) 960 947 914705 827 892 b) d) The temperature programmed reduction (TPR) measurements are given in Fig. 2 and Table 2.
The TPR profiles showed that the reduction of all catalysts occurred in two steps.
The following mechanism has been proposed : NiMoO4 → Ni° + NiMo alloy + MoO2 Ni° + NiMo alloy + MoO2 → Ni° + Mo° According to the literature data [7.8], the reduction of NiMoO4 continues until the metallic state.
Fig. 2: Temperature programmed reduction profiles of unsupported and supported catalysts.
This enhancement could be attributed to the in situ reduction of the solid surface by the reaction mixture during the catalytic test.

A new reduction strategy is proposed for training support vector machines.
Sample set select Adult data set of UCI[13], Adult data set has been widely used to test the classification algorithm.
Adult data sets totally divided into nine groups, we use the a5a, a6a data sets to do the experiment, the sample is 123-dimensional vector.
Table 1 shows the experimental results on a5a and a6a data sets.
When the order of magnitude of data sets between 103－105, we generally take for the experience value, for the data set which the order of magnitude greater than 105, can reduce the values of r.

Therefore, a majority of the parameters have been modified with local Thailand data.
Therefore, a majority of the parameters have been modified with local Thailand data.
Some data are from journals and Thailand statistical records.
A summary of inventory data sources are shown in Table (2).

Silicon carbide (SiC) powders have been prepared at 1200-1500°C by carbothermal reduction of two kind precursors of carbonl/silica mixtures: coked rice husk with high-carbon content, and gasified rice husk with low-carbon content mixed with carbon powders as an external carbon sources.
The external carbon source is commercially available carbon black powders (CBp,specific surface area[m2/g], average diameter 40 ~ 50 nm).Table 1 presents data on the chemical composition, SBET obtained of these ashes.
To clarify the effect of the nature of carbon on carbothermal reduction, BRHA,a inherent precursor without CBp was prepared in the same way.
The difference of silica structure in two systems would also affect the rate of SiO(g) formation from the reduction of SiO2.
XRD pattern of the powders from system 2 synthesized at various temperatures for 4 h area of the amorphous carbon, and helps in the carbothermal reduction of silica.

The proposed prefetching schemes chose and download the data block which had the higher caching value in advance to reduce data access delay.
We evaluate and compare the proposed schemes using user browsing pattern data and find that prefetching scheme can improve the seeking performance significantly.
To improve user viewing experience, data prefetching has been proposed as a technique for reducing the access latency [1].
These include data caching and data placement [5], trend forecasting [6], Random Seek Support [7].

The present data have revealed the presence in the deformed substructure of a crystallite volume that has rotated towards the {311}<136> component in the interior of <110>//RD fibre grains as a result of a grain fragmentation process.
In total there were 12 rolling passes with an average reduction per pass of 7%.
They depicted the existence of different substructures within the a-fibre type based on different reductions in IF steel.
More extensive data gathering is required in combination with a more fundamental theoretical analysis on the basis of crystal plasticity model.
The present data do not seem to indicate that this is a major source of strain localization here, although not many GBs between misoriented rotated cube grains could be observed.

Currently, these roll bite peaks are approximated with Heat Transfer Coefficients ‘HTC’ macroscopically tuned on measured mill data.
Temperature signals during rolling have been stored using a data acquisition system (16 bits–sampling frequency: 3-5 kHz).
Evaluation of roll surface temperature and heat flux by inverse calculation (model n°1) Influence of strip reduction.
This trend is due to the higher heat dissipated by plastic deformation corresponding to the higher strip reductions.
