And this technology has been verified with a large number of examples and well test data by them.
The longer is the throat, the greater is the friction loss, leading to more pressure reduction.
Pressure in throat increased with the increase of area ratio, leading to reduction of suction capacity for no low pressure region formed in throat.

As the depth increases, the displacement decreases instantly; below the depth of 1.5m, the reduction amplitude of the displacement decreases gradually as the depth increases.
A DH5923 high-speed data acquisition instrument is set up for the signal acquisition.
Fig. 11 shows that damping ditch has a significant effect: 20 meters and 5 meters away from the tamping point, the reduction amplitude of the vibration acceleration are 59% and 65% respectively.

Antares Software was used to collect the data on the elongation of the samples and the measuring of temperature in pre determined periods of time.
The value tf is the final time of fracture, ef correspond to the fracture strain and AR the percentage reduction in area at fracture.
Results presented at Table 1 suggest the high tp values and the reduction of stationary creep rate demonstrate the high creep resistance when it’s treated by PIII treatment.

(4)Neutron log mainly measures the deceleration degree of fast neutron emitted by neutron source through the formation.And hydrogen is the most powerful moderator in formation,so the reduction ability is related to hydrogen index.Generally ,the hydrogen index of rock skeleton is zero.Besides,the hydrogen index of in carve is higher than normal compaction ones;that is to say,measuring the reduction of rock properties in carbonate formation can also reflect the development of crack.therefore this paper optimizes the well and layer of bigger neutron porosity
Taking a acid well of Tarim basin district as an example, the paper optimizes the properties of fractured intervals by applying the mean algorithm and mean square deviation method to the properties of small layers of the well.As is shown in Table1, the 19 small layer properties of the well are optimized as the modeling data through mean square deviation method synthesizing the effect of many factors.

The data displayed for the 100
th cycle of the material shows an increasingly pronounced shift in the
hysteresis curve with elevated temperature.
The 1.8mm diameter wire data is therefore used as a basis for investigation into the computational model.
The experimental data discussed previously was used as the input to the computational model created in ANSYS v10.0.
However if the computational model is put through 100 cycles as with the experimental data (Fig. 7b) the data no longer approximates the behaviour with the computational model remaining as the first cycle.
The computational model performs well against the experimental data used, especially during the first linear elastic region and the loading plateau.

Therefore, analytical pyrolysis of biomass may provide useful data to improve the characteristics of bio-oil [5].
The reduction in oxygen content improves the stability of bio-oil and increases its heating value.
The data were processed based on the compounds in the NIST 05 library.
For tests at 650°C there was a reduction in formation of phenolic compounds and an increase in formation of hydrocarbons, such as 1,3-Butadiene, 2-methyl- (21,92%).
With the increase in pyrolysis temperature of sample 2 there was a reduction in formation of phenolic compounds and an increase in formation of hydrocarbons and acid compounds.

The high content of these elements dissolved into α or β phase of titanium is directly related to the increase in microhardness and reduction of ductility (embrittlement) [5].
Data analysis was performed by using the statistical software R.
Effect of milling time of hydride powders upon the density and oxygen content of sintered samples TiH2 Sintered Ti-6Al-4V [1200 ºC] M [h] Particle Size [μm] Density [g.cm-3] O [%] 1 19.2 4.06 ± 0.07 0.64 ± 0.01 6 7.3 4.08 ± 0.03 1.11 ± 0.01 18 3.2 4.11 ± 0.04 1.41 ± 0.03 The reduction in powder size with increasing milling time resulted in a slight increase in density (Table 4).
Thus, since the sintering can be satisfactorily achieved through the use of shorter milling times, the reduction of powders must be carefully applied.
Microstructural data regarding the solubilization of vanadium in the Ti-6Al-4V alloy suggest that stabilization of β phase can be successfully achieved at temperatures around 1200 °C [14], even if the use of longer periods of time is necessary.

Both are prepared from coconut shells by thermal reduction method and doping process employing wet mixing.
Experimental rGO was prepared from coconut shell charcoal powder using thermal reduction method.
However, in the insertion process of Na into rGO might not form a new phase as reflected by the XRD data (Fig.1).
This phenomenon might be supported by XRD data, which shows the broad feature of the peak indicating a smaller grain size.
