The film properties, in most cases, are influenced by the elemental composition of the PZT, the type of substrate, the crystallization temperature, the orientation and size of the PZT crystal grains and a number of other factors.
XRD patterns of PZT films (Samples number is on right) a) b) Figure 2.
PZT crystallite size Sample number Pressure [Torr] Crystallographic orientation of PZT (001) (110) (111) (002) 00.15.18 0.51 14.9 85 6.1 9.1 03.19 0.51 - 52.2 01.19 0.45 23.5 104.4 - - It can be seen from the Table 1 that for all samples the size of crystallites with the (110) orientation is much larger than the sizes of crystallites with orientation in other directions.

Indicators of quality of spinning is mainly reflected in: combed indicators, combed evenness CV value indicators, the combed sliver impurities grains, and comber containing short fiber content should meet the requirements.
Optimize the ratio of teeth numbers of the dimensions of the detaching roller drive components and differential gear train.  
On the other hand, it also needs to optimize the ratio of the number of teeth of the planetary gear train. 
Produced by Rieter E62, E72 Comber, the use of computer-aided design optimization technology is the ratio of the number of teeth of the size differential gear train transmission parts detaching roller fully optimized to shorten the effective length.

A number of data from literature are rearranged on fatigue strength diagrams based on the hypothesis of plastic adaptation.
A number of data from literature including fatigue test results of notched and mean stressed specimens are rearranged on fatigue strength diagrams based on the hypothesis of plastic adaptation.
Pileups of interstitial type prismatic dislocations also causes grain boundary cracking, twin-boundary cracking, debonding of inclusions and so on.

The water-cement ratio was 0.6, maximum size of grain was 16 mm and Portland cement 42.5 MPa was used for the concrete.
It is then possible to define the function dependency between the number of fibers in concrete x and the axial tensile strength based on the three-point bending test: fct,3B = 0.0169x + 2.0557[MPa] (R2= 0.9694) (5) Similarly also dependency for axial tensile strength based on the four-point bending test: fct,4B = 0.0166x + 1.8089[MPa].
(R2= 0.9686) (7) Fig. 3: Tensile strength: 3B – three-point test, 4B – four-point test, 3B + 4B + PT – three-point, four-point tests, split tension Discussion Resulting cube and cylindrical pressure strengths are influenced by amount of fibers but it is also influenced significantly with fibre orientation, which may lead to the fact that the resulting pressure strength fluctuates with the number of added fibers.
With increasing number of fibers, the fluctuation of measured tensile strength values also increases.

The grassland ecology is facing multi-pressures such as the balance between the coexistence of grain, forest, human and livestock with grassland [2].
The direct cause of destroying the grassland is not because of the number of livestock, but rather the antagonism between industrialization and urbanization of pastoral areas and the sustainable way of ecological construction in grassland.
Inner Mongolia was the largest number of provinces and autonomous regions of grassland violations.
There were 16226 cases of all kinds of grassland illegal events throughout the year, and Account for 87% of the total number of the country.

But on-line monitoring of SCC is a gray area of research with a number of non-destructive testing techniques being studied for the purpose of early detection of degradation by corrosion [5].
HAZ is most sensitive to SCC owing to wide grain, uneven microstructure and chemical composition, Fig. 2 shows SEM images of the Sample A weld surface before corrosion and after 9 days corrosion.
(1) Where Xi is the testing potential data, N is the number of point used (1024 points).
(2) Where N is the number of point used (1024 points), S is Standard deviation.

A number of methods of thermocycling are known, but the choice of TCM modes is still conducted empirically.
The number of quenching cycles was determined empirically, when the maximum strength properties were reached.

The  basement is consist of Yanshanian fine-grained granite and underlying bedrock is Ordovician schist.
Because of uncertain boundary of stone tongue, adoption of drilling holes machine exploration will bring numbers of superficia drilling holes, increased difficulties of construction and slow engineering progress.
Boundary Definition.Numbers of first-hand datum of stone tongue shape were obtained in construction process(Fig.1), but drain board of  construction boundary can’t be ascertained.
Fig. 3 Graphic well log of GJ9 and GJ10 drill Study on Strengthening Technology Strengthening Technology of the Boundary of Stone Tongue.Pile pipe often meet stones and hardpan can’t be pierced when vibrating plate inserting machine is used because of loose construct mountain stone near the stone tongue from 8 m to 12m. vibrating plate inserting machine was used and 75-80% drain board can be successful inserted(Compared with the design number) when shallow hole drill was used.There is thin silt in the region and its thickness is from 5.0 to 8.0m Strengthening Technology of Silt at the bBottom of Stone Tongue.Superficia drilling holes had been used to pierce stone tongue and then drain board were inserted in view of the wedge silt.
