Introduction Based on the "2012 Environment in China" statistical data ,the problem of trans-boundary water pollution is out of control in recent year.Since deterioration of water resource seriously restricts China's economic and environmental development, solving the problem of trans-boundary water pollution is an imminent task.
Q (t) expresses the stock of water pollution at period t, Q (t)> 0, dQ (t) is the state variable of water pollution, water pollution changing process can be calculated as follows : (1) Notice: is water pollution emissions associated with unit economic output.E represents total economic output, represent the effective emission reductions when government paid efforts,r represents the amount of pollution natural attenuation [6]

Relevant data show that global concrete usage up to 7 billion tones in 2003, only China's concrete production is 1.5 billion cubic meters, and has a rising trend.
Fig. 2 Different sources of compressive strength of recycled concrete and recycled concrete replacement rate It is generally believed that under the condition of the same water cement ratio, the compressive strength of recycled concrete increased with the increase of recycled aggregate quantity is reduced(As shown in figure 3), but the reduction with prolongation of the reduced.

The storage structure of processed image data in camera memory is described in [1, 2, 3].
Center of the „BoundingBox“ has then the coordinates Cx = (MinX+MaxX)/2 Cy = (MinY+MaxY)/2 The deviation of "BoundingBox" from the center of the captured image [80,60] is ΔX = Cx – 80 ΔY = Cy – 60 This deviation is necessary to transform at the angle servo motors adjusting the orientation of the camera αH /(camera resolution in X direction) = (170 steps)/(160 pixels) = 1.0625 ≅ 1 step per pixel αV /(camera resolution in Y direction) = (126 steps)/(120 pixels) = 1.05 ≅ 1 step per pixel Then corresponding reduction of deviation of "Bounding Box" center from the center of the image in the number of correction steps of servo is given as Pan = VerticalServoPresentPosition - ΔX Tilt = HorizontalServoPresentPosition - ΔY Fig. 2 Determination of the number of detected pixels depending on the position of the object in the camera field of view The sensitivity of HaViMo2 module was determined experimentally.

With the obtained data were plotted the graphics QOP= f (I) for the steel bars S6-5-3, X210Cr12, 41Cr4.
By decreasing the quantity of removed metal from the work piece, the reaction will be: 2H2O ® O2 + 4H+ + 4e- (4) During anodic dissolution results NaCl by NaClO3 reduction: 6Fe+2 + NaClO3 + 3H2O ® 6Fe+3 +NaCl+6HO- (5) These processes are influenced by the oxide film from the work piece surface that is porous and promotes the rapid passing of cations (metal ions).

Performance Evaluation 100 tasks were generated to compare the thermal reduction achieved by our task scheduling algorithm with LTEDF.
From the above data, we can see that LB_DVFS are save much more energy than LTEDF because of using load balancing and DVFS technology.

In addition, for the purpose of use as important data in preparation of nationwide measures against power failure, important implications about construction of emergency power facilities were obtained by investigating life sustainable time, minimum power demand, and cost bearing intention.
Households that experienced direct financial loss such as 「Damaging of home appliances」 and 「Reduction in actual income from household budget management problem」 were found to be 4% and 6%, respectively.

Flowchart of algorithm Parameter Design For electric furnace at room temperature, plus the 30% range control, data collection to identify the model of the furnace as follow: (11) The following discussion will be the parameters of the DMC algorithm design, the choice of the parameters will directly affect the control performance of the system. 1.
M-value characterization allows more step control incremental changes, thereby increasing the flexibility of control, can bring fast response, but may cause instability, and reduces allows the computation to a significant reduction.
