The affecting factors of the low-temperature activation were comprehensively expounded, such as precursor introduction method, preparation method, supporter pretreatment and catalyst structure.
However, those factors are the key to improve the low temperature activities.
The purpose of our paper is to sum up the present state of different influence factors.
All of them greatly affected surface properties and pore structure of the supporters, leading a promoting effect on catalytic activity.
Effect of SO2 and H2O on low temperature SCR behavior Affecting mechanism of SO2 and H2O.

The mechanical properties of the porous layer are poor.
Fig.1 The test method of coating hardness Fig.2 The coating surface microstructure Result and Discussion Formation of coating properties.
The mechanical properties of coating including hardness, wear resistance, et al. form in the last stage, and are due to the big discharge spark.
It is likely that these properties are the result of thermolysis process of anionic complexes, which occur in the near-anode region on the boundary of * DSA10 is the chemicals invented to treat Al by company.
Therefore, the factors that can promote the proportion of the crystalline phase in the whole coating all improve the coating hardness.

Thermo-mechanical fatigue properties of thin films on flexible and rigid substrates have been investigated extensively.
A detailed overview of the mechanical properties of the Cu layers can be found in table 1.
Thus due to Table 1: Grain size and mechanical properties of the Cu films.

Introduction Diagenetic facies are rock bodies defined by distinctive diagenetic textures, which are core elements to determine the reservoir properties and hydrocarbon accumulation [1,2].
The diagenetic processes that affected the Paleocene sandstones in Lishui Sag include compaction, cementation, dissolution, and metasomatism, based on thin sections, scanning electron microscopy and X-ray diffraction.
Besides, they are also major factors affecting reservoir sensitivity.
Distribution and characteristic of diagenetic facies By settling single factor diagenetic facies to analysis of wells (Fig. 2), it is convenient for us to understand the spatial distribution of diagenetic facies.
Diagenetic facies are key factors to affect reservoir quality, especially porosity and permeability.

Introduction Magnesium alloy has been used in the 3C and transportation industries as well as other structural applications because of high strength-to-weight ratios, anti-electromagnetic field properties and high thermal conductivity [1, 2].
It shows that most films mentioned above present good corrosion resistance and mechanical properties while remain many problems such as weak bonding between film and substrate, residual stress for further study and potential applications.
TiAlN film is characterized with excellent mechanical properties and good chemical stability [12].
The effect of different partial pressure of N2/Ar in magnetron sputtering process on the microstructure and properties of TiAlN films was explored by means of SEM, XRD and tests of microhardness, hydrophile.
Moreover, changes of the ratio of reactive gas may lead to a change in the adsorption-reaction dynamics during the deposition process, which is one of the factors that affect the film surface morphology and preferred orientation [15].

After learning about the law of bolt-end connection-function influenced by parameters of bolt-end structure, how to analyze influence each factor to the bolt mechanical property and to find out the optimal bolt-end structure is main research content.
It is an experiment about three factors and three levels.
As for indentation depth, according to range, it is easy to know that both connection strength and elongation are important factors, and A2 is better, so the reasonable indentation depth is 1.5mm.
At the same time, compared with other factors, B is the second cause and both B1 and B2 are same for different connection strength.B2 is the appropriate.
When it comes to range, all C factors are non-essential, so C2 is good at saving cost and its yield strength is 235MPa.

Nevertheless there are also disadvantages for these reinforcing methods such as complex fabrication, affecting the appearance and poor corrosion resistance.
Fig. 1 CHS T-joint reinforced with CFRP Through the uni-axial tensile test of the steel material, the material properties of the Q235B steel used in the specimens are determined, and the material properties of CFRP are obtained from Product Descriptions.
Considering the anisotropy and negligible mechanical properties in thickness of CFRP, Lamina is used to define the material, and CFRP built by shell element (S4 as analysis element) is defined as the elastic material with failure strain (3000me).
(2) Reinforcing performance of CFRP is affected by the following factors: (a) The reinforcing effect increases with the bigger b of chord.
(e) Pasting length affects the static strength of T-joint slightly.

However, like other buildings, university buildings built for learning is also disposes to the forces of change released by various factors.
Nevertheless, all buildings deteriorate and decay with age as a result of various factors, including poor quality materials, bad workmanship, excessive usage, abuse and inadequate and poor maintenance.
The following provides the description of health risk and safety risk: a) Health Risk: Associated with human health effects; either direct or indirect exposure of building factors that can cause health risks.
It also demonstrates that there is a plethora of risk factors with the potential to affect the different dimensions of building performance.

The influence charts reflect the degree which the concerned parameter affects on the system vibration.
In these parameters, the variation of damping will not affect the inherent property of the system, but only change the amplitude of the response.
Though the integrated errors and exterior force have great effect on system vibration, the influencing law of these two factors is easy to find.
The mean mesh stiffness affects the vibration of input bearing to some extent, but not greatly.

It is well-known that the mechanical properties of nanocomposites are better than those of conventional composites.
Along with this, considerable studies have been performed on the mechanical properties of MMT/polymer nanocomposites [4-5].
For MMT/polymer nanocomposites to have better mechanical characteristics than existing particle-reinforcing composites, it is important to appropriately insert polymer matrix between MMT layers, which is affected by its dispersibility.
This acts as microcrack or void, thereby working as a factor that decreases the tensile characteristics.
