The method of selective catalytic reduction (SCR) is now one of the mature applications of NOx removal technology, which can meet the practical requirements due to the more stringent laws and regulations on air pollutions.
The method of selective catalytic reduction (SCR) has become the main denitration technology due to its high efficiency.
Supported metal oxide catalyst Al2O3 has high thermal stability, and its surface acidic site is helpful to adsorption and reduction of nitrogen oxides, so it is widely used as metal oxide catalyst support.
Experiment data showed that the existence of H2O inhibited the catalytic reaction.

Using the elimination strategy, the primary vibration source was determined, the vibration serviceability of the residential building was assessed by the environmental vibration tests, and the measures for vibration reduction were proposed.
By applying the measures for vibration reduction to Mill Ⅱ and reinforcing the residential building, the vibration serviceability can be improved. 1 Introduction A residential building, constructed by brick-concrete structure and completed in 2001, is six-layer and two-household with a storey height and a building area, respectively of 3.2m and 960㎡ in each storey, whose floor plan is shown in Fig1.
(2) Vibration reduction measures should be applied to improve Mill Ⅱ

Encryption/ decryption circuits are one of the best candidates for low power implementation, as they are needed to maintain the privacy and security of user data.
Introduction Cryptography is considered as a backbone for security of data transmission.
Increasing the data path to process the whole matrix of traditional MC modules instead of processing column by column to reach the goal of high throughput is utilized in [6].
AES internally processes data blocks as matrix of bytes called state.
AES algorithm is a symmetric blocks cipher that processes data block of 128, 192 and 256 bits using keys of the same length.

In order to study its vibration reduction effect, modal calculation and wheel-set drop simulation have been analyzed in this paper.
Even in the most difficult conditions it also can have the role of vibration reduction.
So in order to achieve a better vibration reduction effort, the stiffness of TMD should match the stiffness of fasteners.
As the increase of the mass of tuned system, vibration reduction performance is better.
The wheel-set drop simulation shows the parameters have influence to the track vibration reduction.

With increasing temperature from 300 to 1000 oC, the selectivity for hydrogen and carbon monoxide increased significantly along with a reduction in methane selectivity.
Since acetic acid is one of the major components in the bio-oil [2], it has often been used as a model compound of bio-oil and study of acetic acid steam reforming (AASR) can provide valuable data for hydrogen production from the real bio-oil.
This work provides the thermodynamical data necessary for hydrogen production by the AASR.
The selectivity for hydrogen and carbon monoxide increased significantly with increasing temperature along with a reduction in methane selectivity.
By increasing the WAFR, hydrogen selectivity can be increased with a reduction in carbon monoxide selectivity by increased water-gas shift reaction.

The data was collected for 15 minutes for each light shelf.
The heat transfer process was simulated every 0.5 sec by formulating a custom-developed program, and the data collected was compared with experimental data.
Experimental data vs. simulation data surface finish, each light shelf will have a specular and diffuse reflection component.
They were compared with the experimental data for all samples.

For instance, under the same deformation condition (5% reduction in thickness), dislocation density is the order of 10 14 m -2 in a coarse grained material (mean grain size; 20µm), while it reaches 7×10 15 m -2 in an ultrafine grained material (0.25µm).
A real work hardening behavior can not be detected during necking deformation due to the reduction of sectional area of test pieces.
Fig. 3 shows changes in 0.2% proof stress for the materials with different grain size (20µm, 0.35µm and 0.25µm) as a function of prior cold-rolling reduction.
This Bailey-Hirsch equation is constructed by the data up to the dislocation density of about 10 15 m -2 for iron with large grain size, but if we can accept the linearity to 10 16 m -2 , a large yield stress of 1.1GPa is expected for the iron with this dislocation density.
The data in Fig. 3 clearly shows the change of strengthening mechanism, that is, yield stress is almost constant up to 5% deformation and increasing gradually above 5% deformation.

The results state that the low temperature reduction degradation property in low silicon sintered ore is to achieve the best when the carbon content was 3.7%.
Through the sintering pot test and sinter metallurgical properties experiment, obtain experimental data as is shown in table 1.
This is the Brazilian powder's own properties; general the sinter ore low temperature reduction degradation rate is higher which hematite as the sinter raw material, but the sinter ore low temperature reduction degradation rate is lower which magnetite as the sinter raw material.This experiment using the powder of Brazil as the research object, Brazil powder mainly composed of hematite, therefore the sinter free Fe2O3 more, so with Brazilian powder increasing, vertical burning speed and yield of the sintered ore is smaller, wear-resistance performance degradation, make the screening proportion of sintered ore little graded obviously increased, so with Brazilian powder increasing, the sinter quality fractal dimension will become larger.
At the same time must point out that the Brazilian powder belong to high alumina low silicon powder, with Brazilian powder increasing, the Al2O3 content of finished sinter is increased significantly, which is conducive to promoting the formation of acicular structure calcium ferrite, amount of Al2O3 content is benefit to the sinter[4], but the content can’t exorbitant, otherwise, it can make the sinter of low temperature reduction degradation rate increased, sinter quality drops, also can obviously improve the sinter quality fractal dimension.

Data from this research can be used as the guideline suggestion for the welding procedure specificcation (WPS) and the procedure qualification record (PQR) for the welding repair in the peroid of maintenace. 1.
From the calculated data, the cooling rate of the used tube was higher than that of the new tube with all distances because the effect of carburization, carbon (c) content in the matrix promoted the thermal conductivity properties of the used tube.

The criteria of tensile strength No.TS-001 specimen was accepted because its reduction was less than 5% of the minimum specified tensile strength of two base metal without welding (new and used tubes shown in Table 1) while No.TS-002 was unaccepted because its reduction was more than 5% [9].
