So, another technique of dislocation reduction by in-situ mask (SiNx) drawed more attentions of the reachers [8, 9].
FWHM of (002) diffraction decreased first and then increased with SiH4 follow rate, and the lowest data was 257 arcsec. as 1.0 sccm.
FWHM of (102) diffraction increased monotonously with SiH4 follow rate, and the lowest data was 286 arcsec at 0.5 sccm.
The FWHM and related intensity of GaN spectra showed the same trace with SiH4 flow rate, both got the lowest data at 1.0 sccm.

Effects of grain refinement on LCF behavior of CM247LC at 760 � were found to be reduction of data scatter and increase of minimum fatigue life.
The relatively wide band of fatigue data with CG specimens might be attributed to the anisotropy in deformation of Ni-base superalloys [2,3].
Due to anisotropic deformation characteristics, FG specimen may have relatively uniform LCF lives compared with large band of data scatter in CG specimen.

Taking into account the changes of torque transmitting characteristics with temperature increasing, the clutch control strategy should be changed to avoid the quality reduction of gear shifting and the thermal damage of clutch.
It is a free two-way wireless communications technology working in the 2.4 GHz band with low complexity, low power, low data rate and low-cost.
Meanwhile, DS1621 transfers the data of cold junction temperature to MCU through I2C bus.
After that, these data are packed as the Fig. 8 shows and be sent out through Zigbee wireless every 10ms.

The results obtained in the analyses agree well with experimental data.
Taking tensile loading as an example, because w(f) is a monotonically decreasing function, and all other quantities in Eq. (6) are positive, the increase in the void volume fraction f results in a reduction in the deviatoric stress ijds .
The computed results will be compared with test data.
The experimental data were obtained from tensile tests conducted on an Instron 1342 material testing system.

The decreased intensities of FT-IR and 1HNMR peaks are ascribed to the scission of chain and reduction of molecular weight of PEO by irradiation.
This results are consistence with FTIR and 1HNMR data.
It is consistent with DSC data (Table 1).

Thus, the data on mechanical properties are integral values, which - although they represent general regularities - cannot make it clear to what extent mechanical properties across the sample are changed after ECAP.
Elongation (δ5) distribution across the sample: ∆ upside (Z=2.6 mm), ○ middle (Z=0.0 mm), □ downside (Z=−2.6 mm) In comparing the data of Fig. 2 and Figs. 3-5, one should note that the strength properties (tensile strength and conventional yield strength) measured in standard and small-size specimens are practically identical irrespective of the pressing route and the number of passes.
This is attributed to the size effect, which manifests itself in the decrease in plasticity with the reduction of the specimens' size [3].
The data of Figs. 3-5 show that the strength properties in the initial-state material are distributed highly uniformly, whereas elongation has considerable heterogeneity.

Reactive power and voltage coordinated control strategy Figure1 Wind farm reactive power optimization control system This paper wind farm reactive voltage optimization goal is: ensure the stability of the pcc voltage and meet the constraint conditions, control the wind farm reactive power output to achieve the stability of the machine voltage and the reduction in the network loss.
The control steps Wind farm reactive power and voltage control steps as follows: 1) Get real-time operational data , the control instruction of PCC voltage and wind turbine terminal voltage from the wind farm data monitoring platform; 2) Determine whether control dead zone, if the control dead zone, then control over; If not, then in step 3; 3) Calculate the reactive power source output range, establish the reactive voltage control mathematical model; 4)Set the parameters such as particle number, number of iterations in the algorithm, random initialization of the velocity and position of each particle. 5) Calculate the fitness of each particle, get the particle individual optimal value pbest and global optimal value gbest;6) Update each particle's position and velocity, weights and learning factor; 7) If reach the pre-set number of iterations, then stop the search, or turn to step 5;8) Determine whether the data is reasonable, if reasonable then control execution, if not then alarm.

The structural efficiency of the CFST arch bridge system is due to reduction in bending moments by the use of arches and ties, confinement effect provided by the steel tube to concrete, effect of post tensioning in reducing tensile stresses in ties, composite action which improves the flexural capacity of the ties. [5] This form of bridge system improves the aesthetic quality of the bridge and seismic behavior is desirable.
