After performing a linear fit for t/ε vs. t data, as seen in the inset of Fig. 3, εb and td/ε were obtained from the reciprocal of the slope and the y axis-intercept, yielding εb=15 and td/εd=3.1.
A direct analysis of our data is made by plotting the coercive voltage as a function of film thickness.
The measured data can be described by a linear relation between Vc and t, which agrees with the blocking dead layer model[12].
The solid lines are the linear fitting of the experimental data.
Data taken from both heating (dashed curves) and cooling (solid curves) cycles are shown.

The data were analyzed by using standard fitting Igor Pro 9.0 software.
Moreover, the superconducting dome peak (Tc dome) can be confirmed by these two data pressures point.
Thus, the data point was adopted from the temperature region at which an antiferromagnetic spin fluctuation occurred, evidenced by 13C-NMR measurement [8].
The open grey diamond is the data point as magnetic spin fluctuation since there is no anomaly in the resistivity.
A.A.F. analyse all the data and write the first draft.

The experimental data [29] data indicate that the yield strength is particularly strongly dependent upon the hydrogen concentration.
The simple dependence (3) allows us to make a good approximation of the experimental data.
Despite the seeming simplicity of this approach and the large number of published data, not all of them can be used for the approximation.
Almost all experimental data were obtained as a result of the saturation of specimens either in the electrolyte solution or in gaseous hydrogen.
As a result, the data obtained are not suitable for approximation since the hydrogen is localized on the surface.

The results showed that the two kinds of pigment had higher stability to light and heat (unpublished data).Therefore, the pigment extracted from fruits of Padus racemosa and Padus virginiana are new potential forestry sources as natural food colorants.
Data were expressed as mmol cyaniding-3-glucoside equivalents (CGE) per gram dry basis (mmol CGE/g DW).
The colour changes from purple to yellow after reduction can be quantified by its decrease of absorbance at wavelength 517 nm [14] .Fig.2 showed the scavenging activity of pigment extracted from fruits of Padus racemosa and Padus virginiana on DPPH·.
In this assay system, the presence of antioxidant causes the reduction of the Fe3+/ferricyanide complex to the ferrous form (Fe2+) monitored at 700 nm.

The incorporation of fine zircon particles gave a
significant improvement in densification through a reduction in porosity by faster sintering and by
filling of interparticle voids due to the formation of a glassy phase.
Thermal shock test data were in good agreement with the prediction obtained from R''' parameter values.
Conclusions The increase in sintering temperature and addition of fine zircon particles gave a marked improvement in densification through a significant reduction in porosity by faster sintering and by filling of interparticle voids due to the formation of a liquid phase.
Thermal shock parameter R''' and thermal shock data confirmed that a refractory material sintered at 1650 °C with a 20% zircon content showed the highest resistance to crack propagation, indicating a marked improvement in thermal shock resistance.

And the intercalations of TMA and CTA cations were also identified from the IR data shown in Fig.2 and the TG data shown in Fig.3.
In addition, there was a corresponding reduction peak at 0.712V, suggesting the electrochemical behaviors of the zirconium (IV) complex was reversible.
The cyclic voltammetry behaviors of the Zr(HPO4)2·H2O showed a typical reversible process, and indicated that the compound had oxidation and reduction activities.

The most commonly used methods are Pyrolysis Method and Microwave Digestion Method, of which some obvious problems are inevitable,such as their detecting processes are complicated, the detecting periods are long, releasing harmful gases including SO2 and SO3 when digesting the organophosphorus and the data from those methods are scattered[3].
As nano-TiO2 has the advantages of high stability, non-toxic, low cost and it can participate in the light oxidation and reduction reactions in lighting condition, nano-TiO2 is widely used in water treatment field as the catalyst [4].
After that point, the current through the solution beyond the limit current, the ion diffusion effect descends, which leads to the reduction of the ion transfer.
The data shows that the two methods have no significant difference in standard deviation and RSD.

Therefore, the effective ways of reducing the significant security risks of potassium chlorate in pyrotechnics are the increase of the decomposition temperature and the reduction of the decomposition heat release of the potassium chlorate, which is the improvement of thermostability of potassium chlorate.

In particular, the images shown in Fig. 3 illustrate the comparison between the grain size without and with the addition of the NGR for a slow cooling rate where the reduction of the mean grain size after the addition of the NGR is clearly visible.
From the data shown in Fig. 4 it can be seen that the addition of the NGR leads to a better mechanical performance, especially in terms of strain at fracture which increases from almost 12 % to approximately 14 % in addition to a marginal reduction in the variation of the data.

Sue et al. [5] reported that application of cooling air resulted in drastic reduction in tool wear and surface roughness in turning of Inconel 718 and in high speed milling of AISI D2.
The test data of tool temperature for four cooling conditions is shown in Fig. 1.
Experimental data has shown that tool temperature increases with respect to the cutting time.
The reason is because of the reduction of tool temperature by air cooling techniques (see Fig. 1), which helped in reducing abrasion wear by retaining tool hardness and also adhesion and diffusion types of wear which are highly sensitive to temperature.
