The correlation coefficient R between the fitted curve and the original data is 0.99233.
According to the test data and the curve rule analysis, for the aluminum brass alloy, when the erosion particles impact at 15°~45°, the target damage is severe.

Nitrate reduction by an isolated strain of Fe(II)-dependent autotrophic denitrification bacteria Hongyu Wang1, a, Dan Chen1,b and Bin Lv2,c 1School of Civil Engineering, Wuhan University, Wuhan 430072, China 2 School of Environmental Engineering, Wuhan Textile University, Wuhan 430073, China awhydream2000@163.com, bchendanqcf@163.com, c48853456@qq.com Keywords: Fe(II)-dependent autotrophic denitrification; W1; denitrification efficiency; nitrate.
Available technical data, experience, and economics indicated that biological denitrification was more acceptable for nitrate removal than reverse osmosis and ion exchange (Archna et al. 2012).
Shelobolina et al. (2003) considered that some bacteria used to be recognized as ferric iron-reduction heterotrophic bacteria were capable of nitrate-dependent ferrous-iron oxidation as well.
Just because the superfluous nitrogen source could not be used for W1, the reduction rate of nitrate was decreased.

This paper introduces a small steam expander linked to a moderate/small industrial steam boiler to form a small scale cogeneration system for the purpose of energy conservation and carbon-emission reduction.
According to theoretical analysis and experimental data, the output power for the PSSE expander is closely related to the phase angle between the displacer and the piston.
Introduction Because of the recent interest in energy conservation and carbon-emission reduction, creating a high efficiency co-generation system is crucial.
Moreover, the P-V diagram will be plotted via the data of the transient pressure and transient volume.

The objective of the ALM/USAMP Ultra-Large Casting (ULC) project is to assess the manufacturing feasibility, economics and mass reduction potential of large, thin-wall structural castings of aluminum and magnesium as applied to automotive weight reduction.
These detailed data will serve as input to predictive models that will link the as-cast structure to the mechanical response of the material.
In addition, in-field data is being collected from casting suppliers on die pin wear and degradation.
Pelton and colleagues are working on the calculation of phase equilibria and alloy phase diagrams using a Mg thermodynamic data base (FACTSage).
Data were obtained from the literature and directly from organizations around the world involved in each of the processes.

Introduction In case there is no index the great amount of multi-dimensional data with, data querying is quite slow.
The data object region of leaf node stores the information of index data, and the data object region of non-leaf node stores child nodes.
Thus it ensures the sequence ordering of index records in leaf node and a reduction of overlap between non-leaf nodes.
Two data sets are used in the experiments, Intel data set and Bio_Train data set.
N attributes in the data set are selected as the experimental data and converted into FloatStream a data type of VegeBam2.0, and imported into the database.

Step 3: data sources and data acquisition, dynamic index static processing and standardized treatment The premise of integrative hubs layout planning is to acquire data according to indexes determined by evaluation index system.
Because most index can be quantified, data are from related statistics department and traffic management department.
Then through the min-max standardization method treatment, linear transformation is done, the data are fall into interval [0-100].
Step 1: data sources and data collection and dynamic index static processing First data of index determined by evaluation system are collected.
Step 2:standardized treatment Then through the min -max standardization method treatment, linear transformation is done, the data gained from the first step are fall into interval [0-100].

The study of the solid oxide half-cells consisting of cathode and electrolyte it is very important, in way that is the responsible interface for the reduction reaction of the oxygen.
For optimum performance of the SOFC, it is necessary to study the half-cells consisting of cathode and electrolyte, because the region of contact between cathode, electrolyte and oxygen gas, responsible for the oxygen reduction reaction, called Triple Phase Boundary (TPB).
For an increase of the ionic and electronic conductivities, and the catalytic activity of the reduction reaction of the oxygen gas, a functional layer of composite cathode consisting of LSM and YSZ is conformed between the cathode and the electrolyte [4,5].
The characteristics such as enough porosity for the gases transport, raised electronic and ionic conductivities, stability in oxidant atmospheres, compatibility with the electrolyte and raised catalytic activity for oxygen reduction for LSM cathode and LSM/YSZ composite cathode are necessary and, the YSZ electrolyte, in turn, must be dense, solid, present high ionic conductivity and excellent stability in oxidant and reducing environments [1,2,6].
The crystalline structure of phase LSM is hexagonal and for YSZ phase is cubic, in according to data base JCPDS N°89-648 and JCPDS N°81-1551, respectively.

The duplex (+) NS alloys demonstrated very high room-temperature strength after MIF, at that the reduction of ductility.
Annealing of NS alloy at 600°C for 2 hours provides some enhancement of room-temperature strength and reduces plasticity, the data being in conformity with the hardness values reported in [5,10].
This path reduction proves that a smaller area of fracture surfaces and consequently less work is needed for crack growth.
With the reduction in grain size, the SP temperature decreases.
A finer and more uniform structure achieved in INCO 718 billets provides the reduction of the difference in wall thickness of parts during forming operations [8].
