Diffusion in the ferromagnetic regime is slower than expected from an extrapolation of the data obtained in the paramagnetic regime.
The figure is based on the data given in Table 2 of [3].
When calculating the data given in Table 1 we have taken into account the structural relaxations of the atoms in the magnetic system.
It turned out that the curvature in the Arrhenius plots of the experimental diffusion data observed could be well fitted by these theories.
The data on Fe3Si are new. 4.1 The B2 Phase FeAl For the system Fe-Al in the B2 phase (FeAl) and in the D03 phase (Fe3Al) the relation between electronic correlations, magnetism, and structure is very intimate ([26] and references therein).

Dynamic Field Testing The ambient vibration test is an effective and convenient way of analysis to determine the dynamic characteristics of the building, which uses ambient vibration excitation to measure response of the building, by means of high-sensitivity sensor, amplification recording device and the random signal data processing technology.
After data analysis, the dynamic characteristics of the effect of small amplitude have sufficient accuracy[1].
The sensors of datum points did not move.
When seeking damping the data calculated by the INV damping method was stability, high accuracy, good repeatability, to make up for the deficiencies and shortcomings of the half-power law[2].
The calculated period after reduction was relatively large compared with the measured period.

CAD is short for computer aided design, which is a method of using computer technology to process datas in computer memory and to produce patterns in the displayer or plotters.The fields which utilize computer technology for visual design and production are regularly called CG(Computer Graphics) by the world today.
As a result, the similarities hinder the presentation of designers’ personalities and styles. 2.2.3 Reduction of comprehensive design quality Art design is a strong comprehensive discipline, the comprehensive quality of the designers determines the level of the design.
It is convenient to collect data in the early time of design, and easy to capture design inspiration, to save design schemes, and to deliberate design scheme.
While CAD emphasizes skilled operations of software and data and the fine data and modeling.

The thermo-oxidative aging test showed that the surface hardness IRHD of the rubber increased together with a reduction of failure strain.
Test results are compared with macro-mechanical data of tensile strength and failure strain to investigate failure mechanisms on the surface and in the interior of coolant rubber hoses.

The results showed that the MPB mortar met the higher early strength requirement of rapid-repair materials, with compressive strength beyond 50MPa and flexural strength more than 9.1MPa at 3 hours, and at later ages no reduction of strength happened.
Based on these data, MPB mortar with 15% fly ash demonstrated excellent properties as a kind of repair materials in fluidity, early strength, strength development and volume stability.

Abstract:Based on the principle of hydraulics,an effective equipment of hydrodynamic cavitation is designed and built in this paper.The orifice plates with various geometry size were used as hydrodynamic cavitation generator to study the relation ship between many factor,such as,inlet pressure,discharge,flow speed in orifice,and the cavitation number.Analysis of water flow cavitation status for the experimental unit,this device can produce cavitation phenomenon.The methylene blue and spectrophotometer method can capture the free radicals generated successfully.This is an effective way to measuring the free radicals quantitatively in cavitation,moreover it is easy to fulfill.The intensity of cavitation increases with reduction in the cavitation number.By analyzing the influence of cavitation number on concentrations of •OH.It would be strength of hydrodynamic cavitation.The effect of operating parameters,such as inlet press,low speed in orifice and optimum the structure of hydrodynamic cavitation
Water flow cavitation number Cv's impact on the concentration of •OH.At a pressure P=0.12MPa,0.15MPa,0.2MPa,0.25MPa,0.30MPa,were measured under the conditions of the plate 1,2,4,5,6 5 group Cavitator cavitation data.Detecting the concentration of hydroxyl radical in the corresponding state,and to obtain the relationship between the cavitation number and hydroxyl radical production,as shown in Figure 5.
