The SEM proves that along with the increasing of Ho concentration, the surface roughness of BiFeO3 is decreased due to the reduction of defects in the preparation.
It has very wide potential applications such as data storage, sensors, spintronic devices and memory device.
The surface morphology of samples doped by Ho exhibit better microstructures with a good homogeneity, high density, small grain size without appearance of any residual porosity, which can be attributed to the reduction of the lattice imperfection caused by the volatility of bismuth in the preparation of the doped samples.

The tensile strength (TS) and reduction in area (RA) were calculated afterwards to obtain hot ductility curve and hot strength curve of the steel.
The development of CC numerical simulation is constrained for the lack of high temperature mechanical property data of new steels.
In order to quantify the high temperature mechanical properties including hot ductility and strength of the steel, reduction in area (RA) and tensile strength (TS) of the samples were calculated subsequently.

However is important to improve the physical properties to reduction its water absorption and capillarity.
The experimental data were analyzed by analysis of variance, considering completely randomized design.
The higher concentration of stabilizing promoted reduction of water absorption but had no significant effect at 5% (Fig. 6).

The instrument was driven by the Gamry Framework V 4.2 software and the output data were analysed using Echem Analyst V 1.2.
It was also proposed that adsorbed intermediates in reduction of hydrogen ions could cause an inductive loop, and proposed the same hypothesis for the anodic dissolution of aluminium in acidic sodium chloride solution [24, 27].
The Bode plot format is recommended for fitting analysis since all experimental data are equally represented and the phase angle (θ) is a sensitive parameter for indication of additional time constants in the impedance spectrum [31, 32].
This format is preferable for impedance data fitting to equivalent circuit models and it is evident in Figure 4 that a reasonable fit is obtained after overlaying the analysed data from experimental and equivalent circuits [33, 34].
The corresponding equivalent circuits used for fitting the impedance data of (a) Al-Zn and (b) Al-Zn-Sn alloys in seawater.

Collect and aggregate data reporter responsible for data, to filter information edited by production designer visualize news chart.
In order to ensure that detailed and accurate data collection, data within the team set up to assist member correspondent data mining "Times" visual information produced in accordance with 'a data mining a given topic edited data into a drawing of a draft "the order, different invitation text field correspondent involved.
After the news will obscure the visualization of data in graphic form presented to the reader, because the image of the chart itself and intuitive, so that the relationship between the data to show the reader can see from the comparison between the data, mining the data contained the depth of meaning.
Seemingly unrelated to the data, in accordance with the order of time and space in turn arranged in different patterns and colors to express the contrast between the data to be presented at once, this is the role of the intuitive text news simple data list can not be achieved of.

Extensive experimental data on the magnetic properties of PrxY1-xFe3(BO3)4 have been interpreted and good agreement between theory and experiment has been achieved.
Crystals were grown up on seeds in a mode with temperature reduction.
In order to determine the parameters of a crystal-field of PrxY1-xFe3(BO3)4, we have used the experimental data on the temperature dependence of the magnetic susceptibility cс,^с(T) (from 2 to 300 K), magnetization curves Mc,^с(В, T) (up to 50 kOe) and existing information on the structure of the ground multiplet of Pr3+ ion in PrFe3(BO3)4 [4].
The best agreement is achieved for the following sets of the crystal-field parameters (= (x=0.75[x=0.25]), in cm-1): , , , , , . (5) Comparison of the calculation results with experimental data allowed to determine parameters for PrxY1-xFe3(BO3)4 (x=0.75[x=0.25]): the Fe-Fe exchange fields including the intrachain Bdd1 = l1M0 » 438 [386] kOe and interchain Bdd2 = l2M0 » 295 [285] kOe interactions, the f-d exchange field Вfd= lfdM0 » 118 [81] kOe.
Analysis of the experimental data and performed calculations showed, that in Pr0.75Y0.25Fe3(BO3)4 at low temperatures and B = 0, the magnetic moments of the Pr0.75 and Fe-subsystems are oriented along the trigonal axis c (EA state).

Automatic measurement, monitoring and control functions are realized through gathering heat parameters of end-users on time, and analysis, comparing on the gathered data and data from standard meter by microcomputer.
After the operation it will update the data stored in E2PROM.
There has data of IC card heat energy meter.
After IC card is inserted, display module will read data in order below: purchase heat, remaining accumulative heat consumption.
The thinking of main flow chart is that compare read-in flow and temperature data to set value, meanwhile compare heat energy data accumulated to the data from heat energy meter.

The results of testing on prototype show that the control software based on free port communication protocol is reliable, stable and functioning well, meeting the needs of testing, experimentation and data analysis in the development.
Run command and operating parameters is sent down and up with the serial communicate instructions, and then the collected data is processed in PC.
In order to distinguish these instructions from different functions, the first byte of the data packets’ effective bytes (here VB103) is regarded as an operation code, which is checked in the data manipulation interrupt program in controller and leading to the corresponding operating subroutine, the operation codes’ functions and operations are described in Table 3.
interact with each other by sending and receiving data packets when needed as shown in Figure 4.

Material Development A first step was the reduction of the chromium content in the alloys, from 11 up to 9 wt.%, with the effect that tensile strength Rm decreased from about 700 MPa up to 500 MPa at 300 °C.
The effect of undesired impurities was calculated by decay data of the alloying elements, Fig. 2.
At higher irradiation and test temperatures up to 450 °C, the data reached the level of un-irradiated materials, but still with a reduction in elongation, due to the limitation of the thermal stability of interstitial type defects [13].

P-Δ data in the test are recorded sensitively, and shown in Fig 2.
Empirical Correlation between Indentation Elastic Modulus and Single-Sample Partial Unloading Compliance To investigate the similarity between the spherical indentation method and the single-sample partial unloading compliance method, the spherical indentation test is related to the single-sample partial unloading compliance method to obtain the JR-curve by the indentation test data in this paper.
Then using the Eq.7 can be converted to the equivalent J at this time, and β represents the COD reduction coefficient, which take the number of 1.
(8) Where ν and νi represent the poisson ratio of material and pressure head respectively, AC means contact area of the indenter on the sample, Er and Ei are the reduction of elastic modulus of the sample and the elastic modulus of indenter respectively, and stiffness S1 is the slope of unloading part in load-depth curve obtained from indentation test.
Fig.3 Empirical correlations between 1/ED and BEC Through the data processing of other materials, the empirical relationship between the elastic modulus ED and the non-dimensional unloading compliance BEC of the three point bending test was met also.
