Ningbo Tian with the number average molecular weight(Mn) value of 57,000, and the percentage composition of Hv is 2.1%.
By the analysis of WXRD and PLM shows that PHBV’s melting point decreases slightly with the increase of PEG, the crystal grain becomes smaller and the crystallization point decreases significantly; when the PEG is less than 50%, the crystallinity of PHBV remains the same, but if it is more than 50%, the crtstallinity decreases significantly.

Studies have shown that the miniature specimen yield stress data is in fairly good agreement with larger tensile specimen data if sufficient number of grains are maintained in cross section of the miniature tensile test specimen [4].

A study [9] carried out to measure the predictive power of flour and dough properties in determining bread loaf volume and crumb texture by the stepwise regression model and canonical analysis indicate that variables such as, flour protein content, flour falling number, sedimentation index, and dough strength exert influence on the textural properties of bread crumb and bread loaf volume.

Angella et al. [9] has researched the strain distribution developed during asymmetric and symmetric rolling with a large number of passes.

Zinc is also known in general to increase age hardening response, produce intermetallic compounds, refine grain size and improve castability [5].
Even though there were a number of investigative reports in the literature on the alloying of ternary Mg-Ca-Zn alloy, the degradation behavior of fluoride treated Mg-Ca-Zn alloy received no attention.

On the other hand, a number of studies have been carried out to improve the densification and piezoelectric properties of NKN ceramics by adoption of doping elements as modified NKN ceramics [11-23].

The plastic strain of fine-grained subgrade under repeated loads can be determined by the model proposed by Li and Selig [3].
The Deriving calculation formula is Eq.1: Eq.1 In which, is the as a percentage of roadbed accumulated plastic strain, is the surface stress of roadbed, is the compressive strength of roadbed, which can be obtained by the static triaxial loading test, is the applied numbers of repeated load, are regression parameters of roadbed, determined by the roadbed type.

In figure 3, different wiper positions do not cause different spaces between dendritic grains.
As wiper position rises, the numbers of defects increase (Table 4).

Results of the Experiments and Discussion As can be seen in the photograph of the tablet obtained with a MIRA3 TESCAN electron microscope (Fig. 3), the structure of the material is sufficiently fine-grained and homogeneous, which should contribute to a constant composition of the resulting coatings.
This approach makes it possible to quickly carry out a large number of studies in order to obtain more advanced anti-friction, heat-resistant, corrosion-resistant and other functional coatings.

Depending on chemical composition, fabrication requirements, and intended service, nickel alloys are heat treated in order to either to produce recrystallized or softened structure, to put carbides in solid solution and produce a coarse grain size for enhanced stress-rupture properties, to put age-hardening constituents into solid solution or, last but not least, to enhance strength properties by precipitation of a dispersed hardening phase [1, 2].
Use of an iterative approach allows estimation of emissivity coefficient in wide range of temperature, however, increased number of iteration could extend that range. 2) The emissivity coefficient of nickel alloy 718 changes with temperature, which follows the expectations derived from similarity of response of other metallic materials.
