The overall carbothermic reduction to be studied is reaction (1).
Reaction (6) is reportedly difficult to happen[4], so it is hard to obtain the high active [Ti] during the process of the reduction reaction.
The first stage of the reaction is found to be the reduction of ilmenite forming elemental iron and TiO2 or other titanium oxides.
Conclusions This research has found that steel-bonded cemented carbide GT35 composites can be fabricated by carbothermic reduction of ilmenite.

It was interpreted in terms of adsorption-coupled reduction mechanism.
At pH 1, the maximum loading capacity of Cr (VI) according to UV - spectrometer data is 3.37 molkg-1 and that according to ICPS data is 2.1 molkg -1.
At pH 2 also, the maximum capacity evaluated from UV- data is found to be 2.71 molkg -1 and that from ICPS is 2.1 molkg -1.
Because the reduction rate of Cr (VI) to Cr (III) reduction is faster at pH 1 as will be described later; the difference in maximum loading capaities evaluated from UV and ICPS measurement is greater at pH 1 compared to that at pH 2.
The removal mechanism of Cr (VI) was its adsorption followed by reduction i.e. adsorption-coupled reduction mechanism.

By using the sunshine time data from 260 meteorological observation stations in Changjiang river valley from 1960 to 2009, the features of sunshine time in this area are studied.
Materials and methods In this article, the sunshine duration data is taking from the informationization A0, A1 series data files in the Monthly Report of Ground Meteorological Record that collect from each province along Changjiang river valley.
It is in the line with the relevant regulation of Statistical Method of Nationwide Ground Climatologically Data and get from reorganization.
Within the valley and rounding area, there have 260 basic and standard meteorological stations that collect meteorological data from 1960 to 2009.
The spring sunshine reduction is not obvious.

Introduction The reduction of NOx emission is currently a major issue in coal-fired power plant.
The proximate and ultimate analysis data are given in Table 1.
The figures show the data of the left side of the boiler with the zero in abscissa representing the center of the boiler.
The 100% SOFA flow is set as basic data, and the economy changes are calculated in Table 2.
In Table 3, the cases of low SOFA velocity are selected as basic data.

Most countries raised short-term or medium-term emission reduction program from 20 to 50 years in order to act in concert with medium-term emission reduction targets proposed by IPCC.
In the non-cooperative state, reduction strategies of each region will finally achieve Nash equilibrium, defined as.
Then according to the recent ten years emission data of BIS and RUS, we set 90% of CO2 emission of 2010 as the lower limit for the above two regions.
Under the common but differential principle, USA and EU are the key figures in the climate mitigation, which means they take mandatory emission reduction obligation and other countries announce their unilateral reduction commitments according to the reduction intensity of USA and EU.

The isothermal grain growth data from XRD (in situ) of CGO SP thin films are shown in Fig.1b.
From Fig.1b and Tables 2 and 3, both the kinetic model (Eq.(2)) and the current work (Eqs.(7) and (8)) could give good fits to the experimental data.
From Fig. 1c and Tables 2 and 3, both the kinetic model (Eq.(2)) and the current work (Eqs.(7) and (8)) could give good fits to the experimental data.
Unfortunately, in this range there are too few data points in Fig.1c to regard.
Discussions According to the above experimental data (see Figs.1b and c), actually, it is unclear whether a solute drag induced reduction of mobility or a segregation induced decrease in the GB energy is primarily responsible for the sluggish boundary migration.

Defect Reduction in Epilayers for SiC Trench MOSFETs by Enhanced Epitaxial Growth D.
The reduction of critical defects, which resulted in an increase of the predicted die yield, as well as an outlook on future investigations, is discussed.
The reduction in CDs can consequently be seen in an increase of the predicted yield when using a generic 5x5 mm2 die size grid in Fig. 2.
Additionally, it is shown that further growth rate combinations, low buffer/high drift rate combination, resulted in lower critical defects and especially a reduction in device critical triangular stacking faults.
Verifying the defect related improved growth conditions by comparing correlated electrical yield data will be the subject of future investigations.

Thus, this paper firstly built an economic benefits evaluation index system for power generation projects based on low-carbon financial benefits and carbon-emission reduction efficiency.
Their common shortcoming, however, is that the decision of choosing weights totally depends on the expert's experience and preferences with too much arbitrariness and not fully involving the information provided by objective data.
This paper, in the first place, choose those four most commonly-used indices—Net Present Value, Inner Rate of Return, Investment Payback Period, Rate of Return on Investment as low-carbon financial benefit indices [5], and then introduce carbon-reduction investment income rate and carbon-abatement cost into carbon-reduction economic benefit evaluation with comprehensive regard to the viability of procuring carbon-reduction benefit indices of venture construction projects [6].
First of all, normalize and non-dimensionalize the crude data in compliance with the formula (2) to get the standardized decision-making matrix, and the analysis can be seen in table 3.
This paper can find the amendatory measurements through analyzing other projects’ relative drawbacks in comparison with the corresponding data of project A, offer theoretical instructions to the economic benefit assessment of the projects of some certain departments, and help get investment policy privileges, tax incentives, the security of power gridization and so on. 4.

When the input signal Vin = Vref, the output data is 128; Vin> Vref, the output data is greater than 128; otherwise the data is less than 128.
Data acquisition process is shown in Fig.5.
Fig.5 Schematic of data acquisition The data collection part consists of analog circuits and digital circuits.
A/D 1 continuously collects data without the external input signal.
Collect ADC data from channel 1 continuously and determine whether the value of the data acquisition and the standard signal amplitude value are consistent.

Dynamic Data Mining.
Field measurement system various real-time information can be obtained, such as drilling data, log data, logging data and formation evaluation data.
Then these data are transferred to the data mining system module after data processing, which includes a series of handling processing such as noise reduction, type conversions, missing handling, and data description.
The passed data by dynamic data acquisition is the real-time data based on the time slot, and the boundary data might be ignored taking into account of data processing process, therefore, the overlapping Windows technologies are selected to deal with dynamic real-time data.
