Introduction To realize significant cost-saving, increasing of operating pressure and deterioration of serving circumstance[1], properties of strength, toughness, weldability, anti corrosion, anti-HIC and anti-SCC for pipeline steel are more strictly required.
Pipeline steel properties are controlled fundamentally by the chemical composition and the cleaness, especially the content of non-metallic inclusions.
Inclusions are one of the dominant factors affecting HIC which are usually considered as irreversible trap sites in steel [9].
Inclusions, especially the large scale inclusions are the most harmful to mechanical, anti-HIC, anti-SCC and other properties for pipeline steel.
To avoid the influence of inclusions on the properties of pipeline steel and mis-down grade induced by mold entrapment during the period of drastic changing of casting speed, the increasing rate of the casting speed approaching to stead casting state should be adjusted more evenly.

For one or the other the results are different as regards the mechanical properties and microstructure.
Mechanical Properties Fig 11 shows that mortar samples (SC5) exhibit the best mechanical performance at 7 and 28 days compared to mortar samples (SC3) and (SC4).
This phenomenon generally causes the degradation of the binder and leads to falls in final resistances Fig. 13: Mortar samples SC5 Fig.14: Efflorescence geopolymer specimens The content of Na2O (contained in the alkaline solution) is considered as a determining factor affecting the mechanical properties.

The second was that an alkaline condition had a negative affecting on adsorption of color components of activated sludge, and had contributed to dissolution of organic matter.
The metabolic activity will affected by the temperature negatively while the temperature over or below the optimum temperature.
Compared to other influential factors, the culture time and activated sludge concentration were dominant.

The air-gap is changed due to the influence from various factors not only the tolerance of the manufacture and assembly of motorized spindle but also different working condition.
Its dynamic properties play a very important role on performance of high-speed machine tools.
Vibration performance of Motorized spindle affected the processing quality directly.
There are three factors impact on air-gap change, such as temperature of motorized spindle, tolerance of the manufacture and assembly and the eccentricity between the stator and rotor.
Knight, A.M. et al. studied change of air-gap due to mechanical fault by monitoring Stator current [2].

.), and anti-sediment wear properties of dredging machine in dredging vessel has become an important research topic in dredging engineering[1].
The carbon is the main factor affecting the carbides quantity, under normal circumstances, and the higher the carbon content, the higher the number of carbides and wear resistance is increased.
Chromium is the main alloying elements in high chromium cast iron, and content of chromium is the main factors to decide carbide type.
In order to study the impact of different heat treatment parameters on the organization and properties of the wear inserts, alloy E (Shown in Table 1) is taken by heat treatment process experiments.

The form and structure of a building not only depend on the designer's subjective factors, but also depend on the actual and various objective factors: including the application of the building, form and requirements; the surrounding environment and concrete requirements of department of city planning; need to consider the economic inputs, select appropriate materials and construction techniques, besides, a building's form and structure will be affected by the tastes of different investors and users and different local historical and cultural tradition.
In fact, as the social development, there are more and more complex factors that can influence the design thinking.
Therefore, architectural design can be seen as the architect seeking the best balance in the complex network composed of various factors.
The necessary conditions for the birth of a good work is to achieve the most reasonable value on the whole after considering all factors rather than emphasizing a factor and overlooking other factors.
Facing of the complex network of architectural design, the architects must adopt the scientific methodology of complexity science: not only have profound understanding of the various properties of parts, but also grasp the overall macro level integrated; thinking logically thinking as well as non-logically.

The main development of high performance components include diesel engine blocks, automotive powertrains, turbo housings, exhaust manifolds and many other parts in which the combination of strength, weight and heat conductivity properties are of great importance.
Of the present production, iron castings represent more than 75% of all castings worldwide mainly due to the package of physical and mechanical properties associated with competitive costs.

Effects of Graphite Shape on Thermal Fatigue Property of Thin Wall Graphitic Cast Irons Yung-Ning Pan1,a, Chen-Chi Fan1,b and Chih-Hung Chang1,c 1 Department of Mechanical Engineering, National Taiwan University, Taipei, Taiwan a panyn@ntu.edu.tw, bfaner@mail.hsivhs.tpc.edu.tw, cr98522712@ntu.edu.tw Keywords: Cast iron, Thermal fatigue, Thin-walled casting Abstract.
Furthermore, adding some 0.5%Mo to the irons significantly improves the thermal fatigue property, in some cases even by a factor of 2, implying that the role of Mo outweighs the influence of graphite structure in promoting thermal fatigue property.
In order to realize how the thermal fatigue property is affected by the graphite structure, 6-mm section plates were cast for evaluation due to the fact that a meaningful representation of compacted graphite structure can be obtained in this section.
Both properties in turn are related with alloy composition and microstructure [5-11].
Adding some 0.5%Mo to the irons significantly improves the thermal fatigue property, in some cases even by a factor of 2, implying that the role of Mo outweighs the influence of graphite structure in promoting thermal fatigue property.

The degree of dispersion of aluminosilicate and silica components is one of the important factors in the "mineral component - alkaline grout" system [6-9].
The obtained dependences of the specific surface area of mineral powders on the duration of fine grinding allowed us to establish that the grinding process is rather laborious and is determined by various factors.

A critical factor affecting the performance and reliability of KTP in laser system is the quality of the resulting machined surface.
In a previous study, the physical and chemical properties of KTP are discussed in detail, but the machining characters are seldom involved.
On the Lapping Process In the lapping process, the workmaterial is removed by the mechanical and chemical actions between abrasives, workmaterial and environments (water or air).
