Then CO2 emission is calculated in the RHF—EAF flow for treating V-Ti magnetite according to data from the pilot plant in Pangang Group.
Based on the data from design and real production the text calculated the quantum of CO2 emissions.
According to these data above we can calculate the ratio of blast furnace gas and coke oven gas and the result is that among the gas mixture blast furnace gas accounts for 60% ,of course the rest is coke oven gas.
The carbon content of metallized pellets is about 5% and the carbon content in the hot metal is around 2%.According to the mass balance calculation we can get the data of CO2 emissions to produce one ton hot metal.
The calculation is based on the energy consumption which is different from the calculation of the RHF-EAF process and all of the data come from the real production.

Electrode metal powders are generally synthesized by the wet reduction process [1-2], chemical
vapor deposition method [3] and spray dry method [4].
In this study, Ni powders were prepared by the reduction of hydrazine of Ni salts from diethanolamine (DEA) solvent.
Hydrazine hydrate (N2H4⋅H2O) was used as reducing agent and the reduction was allowed to proceed at 180~240 °C for 0~40 minutes.
XRD data revealed the characteristics of nickel crystalline as shown in Fig. 2. 10 20 30 40 50 60 70 80 (c) (b) (a) 2-Theta Intensity (a.u

When reduced, boundary region of neighborhood-based rough set narrows, on the contrary, open out, indicated that the neighborhood-based rough set has a certain degree of tolerance to the data noise, which can enhance the robustness of the produced rules.
The results show that the model can not only deal directly with the continuous attributes, but also has a certain degree of noise tolerance, it can enhance the robustness of data analysis and processing and is better adapted to practical problems in engineering.

Abstract.
Thus, 3D laser scanning was used to acquire geometric feature data, including the length, width, height of unstable rock masses, controlled structural plane, and cutting depth of posterior-margin joints, and to plot the sections of the unstable rock masses (Fig. 2).
Since the saturated cohesion and internal friction angle of unstable rock mass are inaccessible, we adopted similar strata for analogy, and referred to the regional empirical data: 0.21 MPa, 29.8°; the geometric dimensions of the unstable rock masses are showed in Fig. 2.
According to SRM, the slope stability safety factor is defined as the reduction degree of a soil-rock body strength parameter when the slope reaches critical failure, or namely the ratio of actual strength to critical-failure strength of soil-rock body, or namely the reciprocal of the reduction factor [6].

However, in typical image recognition in 1D vectors space, where the number of data samples is smaller than the dimension of data space, suffering from the singularity problem of matrix, NPE algorithm cannot be implemented directly.
However, they are defined only on the training data points and cannot show explicit maps on new testing data points for recognition problem.
In both experiments, we split randomly the data set into two parts.
And relative to 2DLPP and B2DLPP, 2DNPE and B2DNPE have total different ways to preserve local structure of data manifold.
