The pure cotton yarn, the pure SPF-PVA yarn and the blended yarn are of 18tex and 320 twist factor.
This results from the mechanical property of the fibers.
Although the fibers are blended and twisted with each other in forming the yarn, this does not affect or change the facts of the non-matching due to the difference of the mechanical property of the blended fibers.

As the grinding force and grinding temperature is high in conventional wheel grinding, it is easy to cause grinding burns, adhesive wear, thus affecting workpiece surface quality seriously.
The cutting surface distribution shown as shown in fig. 1.[3]After cutting processing, surface integrity requires superficial layer intact, the mechanical and physical properties, microstructure, etc all can meet the application, but also needs to ensure certain service life.
To achieve the above goals, using experimental method to research the surface integrity of titanium alloy TC4 in abrasive belt grinding, mainly include the influence factors of the surface roughness, surface morphology, residual stress, and consequently get reasonable process parameters for better surface integrity of titanium alloy TC4 in abrasive belt grinding.

A significant percentage of buildings are made of Reinforced Concrete (RC), thus determining the mechanical properties of interest such as concrete compressive strength is one of the most crucial issue [1].
Taken individually, the first two techniques are highly dependable on various factors such as humidity, porosity, internal voids or delamination etc. and can lead to faulty results.
Făcăoaru [2] was one of the first researchers who, in the late 60’s, saw the possibility of combining SRH and UPV, thus creating a method less affected by contingency factors whilst delivering high accurate results (SonReb).
The procedure presumes applying some correction factors depending on cement type and dosage, granulometry and nature of aggregates.
The combination of SRH and UPV provides good results even though the two methods are influenced by a various number of factors.

The influence of the microstructural constituents on the mechanical properties is indicated.
Considering Fig. 1, where the influence of the microstructural constituents on the mechanical properties is indicated, the optimum relationship between materials properties and microstructure is expected for a NL γ microstructure.
But it has to be taken into account that all these features affect the mechanical properties of the material, too.
These results led to the determination of a two-step heat-treatment adjusting a NL γ microstructure with balanced mechanical properties.

According to the simulation results, a large 3D ES barrier affects the surface morphology apparently.
Metallic nanordos have been found many useful and unique properties and applied in many fields, such as integrated circuit [4], surface- enhanced Raman scattering [5, 6] and metallic glue [7].
That is to say, a larger 3D ES barrier is a key factor during metallic nanorods formation and growth.

Study on cracking control of high performance concrete at early age Wang Yajun1,a , Wang Jianjun 2,b, GUO Changying1,c, Cao Mengxing 1,d 1Airport department of Air Force Service College, Jiangsu, Xuzhou 221006, China 2 The Seventh-Engineering Corps of China Airport Construction, Shanxi Baoji 721006, China awyj-1972@163.com, bwangjianjun-hm@163.com, cgcy733@163.com, dcaomengxing136@163.com Keywords: High Performance Concrete, crack, shrinkage, mix ratio Abstract: It analyzed the reasons for the early cracks in high-performance concrete, and prepared overall program to improve the mechanical properties and the durability of the HPC.
Generally, we should chose Portland cement with high 28d strength (not lower than grade 42.5) and good rheological properties, and good compatibility with super plasticizer.
These factors not only affected the strength of the concrete but also the work performance of fresh concrete.
In accordance with the judging method ASTM C1202, base concrete was concrete with low permeability, but concrete mixed minerals was concrete with very low permeability and its anti-CL- permeability and corrosion resistance properties were significantly better than the reference concrete.
Conclusion From the analysis above we can see, the HPC mixed with fly ash and mineral fine powder can achieve good mechanical properties and durability by reasonable adjustment of water-binder ratio and scientific selection on mineral admixture and additives.

This paper briefly introduces the use of sound-absorbing materials and sound-proof materials in the buildings, concisely summarizes the factors taken into account in the acoustic design, and then introduces the requirements of architectural acoustics materials in sports venues.

Main Factors Taken into Account in Scientific Acoustic Design In acoustic design, we should take into account two aspects.
Other Factors Affecting Noise Jamming Design of Sports Venues In addition to the noise intensity, noise jamming is related to the duration of the noise spectrum, the number of repeats, human auditory, psychological and physiological characteristics and other factors.
The second one is the noise radiated from mechanical vibration of architectural structures, that is, solid sound.

Titanium alloys are very interesting materials for industrial applications and most titanium alloys have been designed for aeronautical applications, due to their excellent specific properties such as high strength-to-weight ratios, maintaining its strength at high temperatures.
The physical and mechanical properties of Ti-17 are listed in Table 2.
The temperature generated during a machining operation is influenced mainly by the properties of the workpiece, tool material and the machining parameters used.
In many cases, the temperature remains sufficiently high to adversely affect the performance of cutting tools [11].
Therefore, high machining temperature is one of the main factors limiting the machinability of the Ti-17 alloy.
