After the reduction, reaction gas at the certain of temperature, pressure and space velocity was directed to the reaction system for 2h.
Comparing all the data above, we found that as the increasing of Ce, the CO2 conversion and the selectivity of ethylene firstly increase and then decrease.

Introduction Because of good wear resistance , vibration reduction , machinability, and low cost, ductile iron is an important engineering material[1].
In this paper, the thermal physical parameters, which are shown in figure1 (a),(b),(c), are got by material simulation software –JmatPro, and the expression about temperature is got though data fitting.

Data show that as of the end of 2011, there were all kinds of printing companies 102,484, the national scale printing companies were 2439, accounting for only 2.4% in the total number of the whole industry, the output value of these enterprises was 439.69 billion yuan, accounting for only 50.7% of total output value of the whole industry [3].
They always compete with each other by price reduction, resulting in profit margins declining, technological transformation and equipment renewal ability were even lower throughout the industry, if the vicious cycle continues, it will not only make a number of low-end production enterprises have been eliminated, but also drag a group of good business [4].

The relevant information of each micro-source is shown in Table 1 , diesel emission data, the generator pollutants standard of value, fine level as shown in Table 2.
With the development of technology, wind turbine and photovoltaic cost is expected to decline, oil prices will continue to rise, the government and enterprises attach importance to energy-saving and emission reduction, the economy of microgrid will be reflected greatly based on wind-solar complementary characteristics.

The results of numerical investigations are tested by comparing the experimental data, the strain in a plate and a cut under the influence of shock wave loading.
After 3∙10-4 s a drummer rebounds and stress reduction occurs, however permanent deformation remains (Fig. 2).

Scanning mode was fixed reduction rate (CAE), holding time was 100 ms，lens mode was Large Area XL 500 μm， vacuum degree was about 1.07×10-9 Pa.
Avantage 2.14 software was used for data processing.

Mineral insulated K- type thermocouples which have an interface with data acquisition system are inserted into the mold cavity at the centre (T2) as shown in Fig.1 (b) to measure the time – temperature history of the casting.
· Uniform distribution of B4C particulates was observed in the aluminum matrix · The micro structures reveal a drastic reduction in grain size at the chill side when compared to brick side of the casting.

Most of them based on the heterogeneous chemical reaction between TiO2 precursor and reduction agent and allow to production of TiO2 nanomaterials with different morphologies and structure: nanotubes [7], nanobelts [8], spherical colloids [9], nanowires [10], etc.
XRD data were collected in the 2θ range of 20–100º using step scan mode with step width of 0.01° and step time 2.00 s.

Published data showed that the inclusion of tungsten in binary Ni-P deposit positively affected the deposition rate, composition and deposit properties such as hardness, wear resistance, corrosion resistance and thermal stability [5-7, 14-16].
Also, the increase in tungsten content in the deposit results in a reduction of its phosphorus content, and then the coating tends to present a more crystalline structure [14].

Data analysis of the results of simulation model 2.1 Flow diagram analysis According to rupture results that water pressure to cause crack macro crack is by the accumulation of micro cracks and gradual expansion of form, no matter which kind of case is a starting crack pull model, that is drawing displacement.
The experimental results of the initial compaction stage (original porosity closed), stress the temporary reduction on the open loop of concave curve fluctuation and deformation process of the closed-loop form curve appear fluctuations, the numerical calculation without shows.
