To consider different stiffnesses of normal sections along the length l, the rod is divided along the length into an even number of equal sections (at least six).

In the manufacture of microsections, samples were processed on 4 numbers of sandpaper (sanding), followed by polishing by standard technology.
Grain size effect on wear resistance of a nanostructured AISI52100 steel.

Chemical precipitation technique has many advantages such as mild reaction conditions, less energy consumption, simple equipment and there are large numbers of variable factors in the preparation process which can be used.
The crystallite size of copper is calculated using Scherrer’s equation where, D is the grain size, K is a constant taken to be 0.94, λ is the wavelength of the x-ray radiation, β is the full width at half maximum and θ is the angle of diffraction.

Moreover, from outside to inside, there is a great decrease in the number of debris of microbial mycelia, accompanied by a decrease in CaC2O4 content of the rock.
Moreover, crystal grains of calcium oxalate are regular and dense because of participation of microbes.

The bigger ST particles could be the ruptured grains.
The increasing of hydrophilic co-units should avail the hydrolysis of matrix materials, and a number of hydrophilic groups from ST and MAH generally enhanced both the hydrophilicity and the conformation mobility of blends so that the release rate of active ingredient increased.

Fig.1 Figure of forms of reference points (mm) Quaternary artificial accumulation layer and miscellaneous fill soil: grain filling is made up of grave land clay, which color is mainly gray and brown - dark gray.
All the measuring points should be marked with red paint and uniformed numbers, as shown in Fig.2.

It is seen that the grain sizes rang from 0.4 to 0.9 μm in pure NiO and 10 wt% ZnO-added NiO.
The increased porosity may lead to increase the number of reaction sites at the interface between SE and YSZ and then to increase NO sensitivity.

The diameter of ceramic filter material grain was 4mm~6mm, storey was 3.7m.
Water flowed into the next processing unit by gravity so as to reduce the number of pumps.

In the policy context of Smart gird construction ,smart electricity service will generate a lot of "fine-grained with time stamp" user behavior data, which is different from the traditional structured data.
Attackers use Big Data technology to analyze and steal the consumers’ phone numbers , home addresses or other important information, which poses a grave threat to the consumers’ property and personal safety.

The belt developed a series of structural alteration zones of ten to several hundred meters, such as mylonitization belt, coarse grain mylonite belt, phyllonite belt and so on.
Conclusions Through the above analyses and conclusions of gold metallogenic series in Zhejiang Segment of Qinhang Metallogenic，5 kinds of gold metallogenic series are summed up，among which it is the most important that the gold metallogenetic series for the dynamic metamorphism with the largest number and the largest size.
