The microstructure after flow forming reveals elongated grains in the direction of flow and the breaking up of the secondary phases in the microstructure.

The emissivity depends on a number of things such as spectral range, surface conditions, and temperature, etc.
This plastic deformation results in tearing off of the grains of carbide from deforming cobalt layers.

For this treatment the bridges were embedded in fine-grained alumina powder to achieve a wicking effect for careful removing the wax core of the bridging part.
The number of dental parts which can be produced from a given volume of suspension strongly depends on the electrochemical state of suspension.

However, when the temperature of annealing reached 1280℃, the typical three-way type of a b c overburning phenomenon can be observed clearly in the grain boundary.
After a large number of analyses about the simulation data, temperature situation of P3 point is shown in Fig.6.

Similarly, the specific quality of desulfurization wastewater are closely related to the classification of coal, the number of poles of electrostatic precipitator, the air volume of oxidative desulfurization, the concentration control of Cl- in the absorber, the water quality in the desulfurization process and so on
The conversion equation is: (NH4)2CO3 +CaSO4 →CaCO3+(NH4)2SO4 (13) The calcium in FGD gypsum is also an important nutrient the crop needs, which can help crop resist pests and diseases, get the crop stems stout, and the grain plump.

Transducer Pre- amplifier Signal amplificaiton & Filtering Signal aquisition Signal record, processing and analysis system Analysis the location of AE source Sending AE signal AE source Fig.1 Schematic diagram of AE testing technology Application of AE in material detection AE technology used in metal inspection There are many AE sources in metallic materials, such as crack propagation, displacement, grain boundary sliding, etc.
A large number of studies prove that plastic deformation of metal is the mainly AE source, and AE occur mainly in the stage of yield stress.

After we have analyzed the large number of domestic and foreign-related information, and have analyzed the partial discharge signals and various interference signals, and have studied various partial discharge wavelet denoising method in detail, this paper puts forward an improved wavelet threshold denoising method based on existing methods.
White noise interference White noise includes all kinds of random noises, such as transformer winding thermal noise, the grounding grid noise, and the various noises caused by the coupling of the power distribution lines, transformers relay protection signal lines, and the electronic components scattered grain of noise from partial discharge measurement system.

Introduction Iron-aluminides possesses a number of physical and mechanical properties that make them attractive for use at elevated temperatures and in aggressive environments.
For example, HSS made from powder metallurgy bring the both of grain size refining of matrix and uniformly dispersion of hard particle.

The fist was commonly used in solid-liquid adsorption system model analysis, the latter was based on the chemical adsorption of rate control steps, and the third happened in rapid agitation intermittent reactor in the adsorption process often belonging to grain internal diffusion control process[5], whose expression for: ln (1-Qt/Qe) = -K1 t (3) T/Qt=1/ (K2Qe2) +t/Qe (4) Qt= Kit1/ 2 (5) Where Qe (mg/g) and Qt (mg/g) are the amount of dye adsorbed at equilibrium and at time t, respectively.

Visual examination Visual examination of the failed helical gear showed that a number of adjacent teeth and random teeth failed by fatigue, as shown in Fig. 3 (a).
The failed gear outer surface region as shown in Fig. 5 (a) can be seen with a transgranular fracture and intergranular fracture crack propagation is along grain boundaries which these results indicate that the mode of fracture within this outer periphery of the gear was brittle.
