Fig.1 Manganese anode slime removal of lead process route The route design was based on three points: 1st, mechanical polishing could destroy the crystal structure, cause local defects, and make crystal particles in thermodynamic instability state, the particles were activated, the system activation energy was decreased, in the actual processing, anode slime of over 200 mesh continued to grind to more fine; 2nd, high temperature roasting, by changing the crystal space structure to make the embedded impurities expose, destroyed the chemical bond between cation and chemical bonds [MnO6] at the same time; 3rd, the choice of the leaching solution, selecting the appropriate leaching agent could selectively leach out the impurity ion distributed in the manganese compound in the form of a coordination compound, while manganese compounds were insoluble in order to achieve solid- liquid separation.

Roasting environment [19], mainly oxygen partial pressure can affect the roasting temperature selected, oxygen partial pressure reduce, which can make MnO2 every oxygen loss at lower temperature, while, roast atmosphere directly affect heat absorption peak in the TG/DTA, as well as the kinds of roasting production, and whether the product is a pure substance.

Constitutive equations for hot working are of great importance in optimizing forming processes to balance reductions in preheating and force, to avoid defects and to improve properties.
Flow curve shapes and. constitutive parameters are affected by variations in composition, in homogenization, in grain morphology and significantly in texture.

Crack detection of critical beam structures such as bridges and aircraft wings by vibration monitoring is based on understanding how a crack affects the vibration characteristics of a beam structure.
Introduction Beam-type structures are widely employed in both mechanical equipment and civil facilities in which their reliability is usually critically important.
Except the crack depth, all other different factors are considered for the purpose to include their influence on the model if they have and to eliminate calculation errors by statistic procedures.

In the simulation of oil flow electrification process, the relationship between the above four parameters and the three types of influencing factors must be considered [9].
It still could not be determined that which effect was the real mechanical, or it was a combination of several effects.
That’s to say the characteristics of solid surface determined the electrical properties of the oil flow.
But this model thought that the polarity of charges in oil mainly depended on the activity of the positive and negative charged ions in oil, while the surface properties of solid materials only played a supporting adsorption role in the oil flow electrification.

During the deformation process at high temperature, large number of mechanical work is converted to heat energy by means of large plastic deformation and friction force between die and work piece.
Related with many factors, these interface coefficients are very difficult to be directly measured [8-10].
This method needs many passes, and the properties of this integrated structure are poor.

These temperature rises may affect the microstructure of the forging.

It's location in wave band is shown in Fig.1: Fig.1 THz region of the electromagnetic spectrum position Terahertz compared with conventional light sources has many unique properties: transient[2], low-energy , highly absorbed by most polar molecules, high permeability and so on[3].
This property can be used in the THz image since people are usually tested stand in the middle of the THz imaging device.
To focus attention on human body and reduce the noise in the background to affect the selection of seed point.
The location impact factor can be introduced as: (1) where , are the center coordinates of the image.; , are the coordinates of the blocks centre; is the maximum distance from image centre to others point in one image.

A study of the p-c-T isotherms have led to the determination of the thermodynamic properties of Pd-Ce-H alloys [1, 6] and to the conclusion [6] that Ce does not trap H.
It was hoped that the comparison might have shed some light on the classical or quantum-mechanical character of H diffusion as well as on the H-Ce interactions.
The pumping system was based on a mechanical and turbo-molecular pump and the chamber sealing was made by copper gaskets.
Concluding this note it is to be emphasised the following facts: a) the diffusion coefficient of H in disordered PdCe is now known over a wide temperature range, b) the H diffusion rate above 100 K obeys a classical-type of Arrhenius law, c) the H-Ce interaction is basically repulsive and, finally, d) the low temperature IF relaxation P2 is not due to Ce-H pair reorientation but rather to reorientation and reaction of H dipoles of variable symmetry properties located far from Ce atoms.

Introduction Particle reinforced metal matrix composites (PMMC) possess many outstanding properties such as high specific stiffness, high wear resistance, low density, high thermal conductivity, low thermal expansion, low fabrication cost, easy shaping etc.
Volume fraction, average size of SiC particles, tool grain size, coolant and heat-treatment have significant influence on the tool wear (comprehensive analysis of the tool wear mechanisms and the influence factors will be presented in detail in another publication).
However, the waves produced by the periodic feed of the tool nose were the most important fact that affected the surface roughness profile.

The manufactured heat exchanger was visually evaluated for defects that could affect the functionality of the element.
This fact allows for the economical production of mechanical ventilation equipment including heat exchangers made specifically for a given room and a given number of air changes per hour.

Then the mixture solution was placed in a water bath at 85 ℃ under mechanical stirring and simultaneously added concentrated ammonia drop-by-drop to adjust the pH value to 11.
The excellent catalytic degradation properties of N-Fe3C@C catalysts was mainly ascribed two aspects.
The catalytic degradation activity of the N-Fe3C@C-4 catalyst in PMS system would be affected by various factors such as the initial dose of N-Fe3C@C-4 catalyst PMS usage, pH value, and the presence of different anions.
The possible reasons for the deteriorated catalytic properties could be ascribed to the fact that the HCO- 3 anion can not only act as a quencher of SO●- 4 and •OH (Equations (5) and (6)), but also promote the pH value of the catalytic system to alkaline conditions, both of which negatively affecting the TC removal [36,37]. the negative influence of the NO- 3 on the TC removal was attributed to the reduction of the •OH radical in the system (Equation (7)) [38].
