Cost reduction in magnesium alloys would be expected with increasing the volume of magnesium alloys used.
However, the reduction in the cost of producing primary magnesium will have a direct effect on the volume of magnesium alloys used in automotive applications.
Cost reduction in magnesium alloys can also be achieved by increasing its recyclability.
Also, utilization of 2-cavity cold chamber die casting enhances productivity leading to cost reduction.
At the start of design, we gathered all the data available that could impact the magnesium SCLH module being developed.

Test data is collected by using multi-function data collection card.

Optimal Uncorrelated Unsupervised Discriminant Projection Yu’e LIN 1,a ， Yongcun GUO2,b 1School of Computer Science and Engineering, Anhui University of Science and Technology Huainan, 232001, China 2College of Mechanical Engineering, Anhui University of Science and Technology Huainan, 232001, China alinyu_e@126.com, bguoyc@aust.edu.cn Keywords: manifold-based；dimensionality reduction；face recognition；small sample size problem；uncorrelated Abstract.Unsupervised Discriminant Projection (UDP) is a typical manifold-based dimensionality reduction method, and has been successfully applied in face recognition.
PCA constructs a low-dimensional representation of the original data via minimizing the reconstruction error.
But both PCA and LDA fail to explore the essential structure of the data.
A lot of researchers are attracted to straightforwardly find the inherent nonlinear structure of the data and then many manifold-based learning algorithms are proposed.
Defining affinity matrix is as follows (1) Where represents the neighborhood relation between data sampleand .

Compression tests then were subjected to various conditions of deformation temperature, reduction ratio and holding time.
A higher reduction ratio also increases the recrystallized regime due to a rise of stored energy for recrystallization.
And the fine precipitations consist mainly of Nb and the coarse precipitations consist mainly of Ti as presented in EDS data of Fig. 5 (c-1) and (f-1).
And EDS data of the precipitations in (c-1) Nb added alloy and (f-1) Ti+Nb added alloy.
Because the samples are deformed at very high temperature over 1180 °C and low reduction under 50 % relative to general cold rolled samples which are deformed at room temperature and high reduction over 70 %.

In addition, reduction of friction effect is attempted based on the experimental and computational studies using ring specimen made of steel and aluminum alloy [6].

That is, it can be considered that friction effect is decreased by a reduction of the contact area.

Based on the investigation data of Hg in Jiaozhou Bay waters in April, July and October 1986, this paper tried to analysis the horizontal, vertical and seasonal distributions of Hg in Jiaozhou Bay, and to reveal the pollution sources and transfer processes of Hg.
The water environmental capacity of Hg in Jiaozhou Bay had been unable to carry the emission load of Hg, and therefore the reduction of emission as well as the improvement of cyclic utilization ratio were the primary processes for Hg pollution prevention and reduction.
Based on the investigation data of Hg in waters in Jiaozhou bay in April, July and October 1986, the major purpose of this paper were to analysis the horizontal, vertical and seasonal distributions of Hg in Jiaozhou Bay, to reveal the aquatic transfer process of Hg, and to provide basis for decision-making of pollution control.
Data source.
The data was provided by North China Sea Environmental Monitoring Center.

However, the size reduction is still unsatisfied.
The XPS spectra of the calcined powders show the consistent result with the XRD data.
The overall chemical composition is estimated from the thermogravimetric data.
However, the exaggerated reduction of the surface should be limited.
Promoted nucleation relating to the chemical reduction of MnO2 contributes to the size reduction.

Fig.2 X-ray diffractograms of the reaction products Fig.3 Fracture surface of sample (1300℃，℃，℃，℃，2h) (1300℃℃℃℃, 2h) Fig.4 The microstructure of coal gangue The data of the bulk density and the flexural strength is shown as a function of holding time at 1400℃in Fig.5.
When the holding time is shorter than 2h, the extent of reduction is lower, which makes the amount of SiC reduce.
Summary It is possible to produce SiC products from coal gangue and carbon by carbothermal reduction synthesis.
On the other hand, when the temperature is too low or the holding time is too short, the carbothermal reduction will not entirely react.

Suitable mixture ratio of bottom ash and fly ash was 2:1, volume reduction ratio 0.349, and weight reduction ratio 0.4936.
It conducted plasma fusing tests on ashes (bottom ash + fly ash) from refuse incinerators in BOT, to acquire local testing data.
The test of weight and volume reduction ratio was presented in the table below, which showed the data before and after treatments.

In the context of global climate warming, Chinese petrochemical industry undertakes great pressure and responsibilities of CO2 emission reduction under the premise of national energy safety.
Chinese government promised the target of CO2 emission reduction in 2009 Copenhagen Climate Summit.
Such positive data shows most of the petrochemical enterprises have accepted the idea of harmonious development with nature. 81.9% interviewee shows their enterprises have started the mental preparation and technology preparation.
The motivations of technology innovation are showed in Table 1, and the current ways of CO2 emission reduction are listed in Table 2.
The data from Table 2 proves that enterprises generally accepted the idea of cost leadership strategy in practice.
