In this paper, we study the energy-saving in optical data center networks.
Traditional methods of energy-saving have been geared towards reduction of energy consumption in the network [2–4].
However, server utilization is quite low in data centers.
In practical applications, VMs in data centers are dynamically changing.
Since new data centers emerge in different geographic locations, interconnecting these data centers in a way that allows seamless VM migration has become a necessity.

CORED(C) is C relative to D, a relative reduction; otherwise, to step three.
From I = 1 to begin a subset of condition attributes C-A repeat: (1) For each attribute , Calculate the positive region on UI after properties c added A , is 0, Then put out reduction; (2) Find the set of the largest property c-T; (3) Calculate for the branch each attribute q in T, ; (4) I=I+1, calculateand; IF() { put out C relative to D, a reduction, and; if T is not empty, turn(3); Otherwise, turn step 5 } ELSE turn (1) Step 5: Finally get all the relative reduction.
(2) First we consider a,, , , , so, RED1={a, c} is one of reduction
(3) Second, consider the b, , , U/A=U/(C-a), , so, RED2={b, c} is also one of the reduction.

The polylol reduction method was then adopted to prepare the cuprous oxide and activated carbon composite material.
This paper take on the polylol reduction method in activated materials, join the filter parts of tobacco, studies the behaviors that activated carbon/cuprous oxide to degradation HCN.
SEM analysis of samples In order to investigate the distribution of Cu2O on the activated carbon, scanning tunneling microscope was used to analyze Cu2O/AC which was synthesized via polylol reduction method，the results were shown in Figure 1.
The data in Table 2 indicated that the concentration of hydrogen cyanide in the smoke which showed composite activated carbon in the filter has a certain absorption capacity, however, the performance could be improved.

It is shown that for ultrafine grained materials obtained with severe plastic deformation methods, the value of elongation up to fracture fδ does not determine ductility, while the reduction of area up to fracture ψ does determine it.
In material science, ductility of coarse-grained materials is estimated using elongation fδ and reduction of area ψ of a specimen in tension up to fracture.
In the first approximation, using the data in [7], we get the following relation: 55.02 0ln 2               = n n n D D R D
(17) Comparing the Eq. 17 and Eq. 13 shows that neck formation and a subsequent reduction of its smallest cross-section diameter lead to the growth of stress triaxiality and damage intensity.

The weight analysis, and the reduction of the width strut were conducted.
The data in Table 1 is presented in graph form as shown in Fig. 8 and 9, where the symbol of A until F are the same as explained earlier in Fig. 6 and 7.
The data from Table 2 is presented as a graph form as shown in Fig. 10 and 11, where the symbol of A until F are the same as explained earlier in Fig. 6 and 7.

The width strut reduction after acid pickling is only 0.92%.

Introduction Coupling refers to a series of complex processes produced by the information parameters controlled each other and the data information transmitted each other between two information modules and data modules.
Common coupling requires multiple modules to use a common data set.
Control coupling controls other modules through transmitting data information [9,10].
Stamp coupling transmits data information through the module parameters.
Data coupling that is similar to stamp coupling transmits data information through the module parameters too.

Therefore, setting up green, low carbon development concept, focusing on energy-saving and emission reduction,developing the energy consumption carbon footprint research have special practical significance on energy saving and emission reduction and the development of low carbon economy in China.
Research methods and data sources Carbon footprint calculation.
As there is no direct detection carbon emissions data of China at present, most of the studies are based on the energy consumption calculation.
Data source.
In this paper, relevant data derived from " Guangdong Statistical Yearbook ", " China Environment Yearbook ", " China energy statistical yearbook".We selected main fossil fuel (coal, oil, natural gas ) consumption volume data for the carbon footprint calculation of Guangdong Province,and also collected the population, The per capita GDP, total energy consumption per RMB10,000 turnover and the per capita forest land area ( including forest and grassland ) of Guangdong Province in recent years to analyse it.

To the purpose of identifying the origin of the dominant texture components the orientation contrast data were further processed.
Similar data were observed on severely cold rolled ULC steels (95% cold rolling strain), cf. [7].
In the present data also a strong γ-fibre was observed in addition to the emblematic {h11}<1/h,12> fibre which is of technical importance for Fe-Si steels as they will impair the magnetic properties of the material.
The orientation scans of the hot band after 90% rolling reduction is shown in figure 4.
The data of Fig. 3c (i.e.

A complete DRX microstructure occurred at the reduction of 72%.
EBSD was employed by using a Hitachi SU3500 scanning electron microscopy (SEM) and the data was analyzed by the OIM software.
By comparing with the specimen subjected to the reduction of 30%, the rate of static recrystallization of the 49% reduction specimen was higher.
Nevertheless, the texture of the specimen after 49% reduction was higher than that after 30% reduction.
At the full recrystallization, the average grains size of the 30% reduction specimen was more than twice larger than that of the 49% reduction specimen. 3.

OFDM can achieve high data rates with achievable complexity.
Cipher generators at each location create high data rate "random" optical bit streams (cipher) from the specified key at the same bit rate as the data stream to be encrypted.
The optical cipher and data bits are then combined by an exclusive-OR operation at the data rate to generate the encrypted bits.
Finally, the encrypted optical data stream is transmitted to the receiving point.
In fact, the complexity of the all-optical encryption system remains relatively constant as the data rate increases, thus making the system the most attractive at the highest data rates.
