Finally,
it was cold rolled with a 9% thickness reduction.
The 9% thickness reduction practically did not bring any microstructural modification at the optical microscopy level (Fig. 1a).
Figure 1: Optical microscopy of longitudinal section of the samples etched with 2% nital: a) cold rolled 9% thickness reduction; b) after cold reduction and annealing in a salt bath at 760ºC for 5 minutes; c) after cold reduction and annealing in a salt bath at 760ºC for 10 minutes; d) after cold reduction and annealing in a salt bath at 760ºC for 30 minutes.
The results clearly show the experimental difficulty related to the evaluation of the preferential orientation and its relation with the exaggeratedly grown grains using data coming from macrotexture, measured by X-ray diffraction.
Due to the high cold rolling reductions, grain boundary density is high so that there is a considerable amount of SIBM grains.

A modification comprising surface activation, PEG immersing and PEG graft polymerization carried out to provide acceptable blood oxygenator performance, blood compatibility and reduction in heparin consumption at the same time.
Water contact angel reduction from 1100C to 720C shows hydrophilicity enhancement, roughness increasing from 15 to 20 and blood compatibility improvement was investigated by SEM and AFM analysis results respectively.
Static water contact angles of the membrane surface were measured by the sessile drop method at 25 °C under an atmosphere of saturated water vapor with a contact angle goniometer (Data physics OCA15+, Germany) equipped with video capture.
As PEG grafting degree increases, proved by water contact angel reduction, hydrophilicity enhancement can be observed (Fig 3).

Abstract: Using data from 2007 to 2011 as the sample, on the base of analyzing the power consumption overall situation of Sichuan Province, the effects of Sichuan electric consumption, energy consumption characteristics factors, increase the proportion of the reasons were studied.
The proportion of power consumption with energy-saving emission reduction and the upgrading of the industrial structure have a trend of increase.
In order to reduce greenhouse gas emissions, implementation of the national energy-saving emission reduction strategy, issued energy-saving emission reduction targets, "three high" limits the development of the industry, regulation and control policy goal is to save energy, reduce energy consumption, reduce pollutant emissions, will reduce the pollution heavy fossil energy production and consumption, to encourage the development of clean energy.
Therefore, under the influence of energy-saving emission reduction policies, power consumption accounted for the proportion of energy consumption is rising.
Three is the development and utilization of water resources in accordance with the national energy-saving emission reduction strategy.

To provide a comparative indication of the relative strength and reproducibility at each location, the UTS data for the test bars were fitted to the Weibull distribution, Eq. 1 [8].
The UTS data were normalised with respect to the overall geometric mean, (for reasons of commercial sensitivity), although this preserved the relative differences in the data.
The modulus was also unaffected by this transformation, and remains comparable to other published modulus data.
These data alone are insufficient to state that entrainment defects contributed significantly to the above reduction in expected UTS.

According to the data reported, adding VC can improve life of hard alloy about 20%~200%[5].
The data show that the melting point of vanadium lowoxide is higher, and not easy to volatile.
Carbonization atmosphere should be reduction atmosphere to ensure sufficiently carbonation.
Due to the reaction in reduction conditions, the volatile of oxygen in form of carbon CO.
If carbon coefficient is low, carbon reduction is not full and the deoxidizing rate is low.

Besides, developing countries including China are likely to reduce emissions to undertake obligations of mandatory emission reduction facing increasing pressure in the future.
When China needs to undertake mandatory emission reduction obligations, the demand sides of carbon assets will add another side that is enterprises which can not achieve emission reduction targets, they can gain over-quota or which to buy emissions permits certain Number to complete their own emission reduction targets
