Results shown that the main chemical reaction was oxidation-reduction reaction of sulfur dioxide and manganese dioxide with a high reaction velocity and desulphurization efficiency at the first stage.
From the point of chemical reaction, the oxidation-reduction reaction between SO2 from sintering flue gas and MnO2 from pyrolusite is proceed easily with the production of Mn2+ and SO42- in water solution[4,5].
Manganese dioxide plays a crucial role in sintering flue gas desulphurization process by pyrolusite slurry with the dominanting chemical reaction of oxidation-reduction reaction between sulfur dioxide and manganese dioxide.
In the meanwhile, the chemical reaction equilibrium constant of reaction (2) is less than that of reaction (1) in same pyrolusite water solution according to the chemical thermodynamic data.
(2) The oxidation-reduction reaction of SO2 and MnO2 is the dominanting desulphurization reaction with a high desulphurization speed and efficient in the first stage of sintering flue gas desulphurization with pyrolusite slurry

Three principal components are extracted as the new variables to provide reference to the cationic pigment dyeing process control and to obtain the best effect of energy saving and emission reduction.
Then the pigment gets seated on the fabric with the help of binder to obtain enough color fastness, it can simplify the technological process and is conducive to energy saving and emission reduction[2].
The data fitting are shown in Fig.2 ,Fig.3, Fig.4,Fig.5 and Fig.6.
Considering to obtain a better energy saving and emission reduction.
Conclusion 1.Cationic pigment dyeing process does not need to modification, and it realizes one bath dyeing to simplify the technological process and is conducive to energy saving and emission reduction. 2.The binder could increase color fastness of fabric, but the dosage of binder should be controlled, otherwise affect product handle.

Langmuir isotherm fits well to the experimental equilibrium data.
In addition, equilibrium data for nitrogen on a commercially available zeolite sample (RS-10 from UOP Inc.) at 274.15 K are also included in the figure or comparison.
Equilibrium isotherm parameters obtained by fitting the experimental data with Langmuir model are tabulated in Table 1.
Table 1 gives the isotherm parameters obtained by non linear regression of the data.
The equilibrium data is represented well by the Langmuir model.

Table 2 presents details of testing conditions and particle size distribution data obtained by laser diffraction such as d10, d20, d30, d50, d80, d90, the surface mean diameter D[3,2] and the volume mean diameter D[4,3].
Summary data of physical properties of raw powders and sands.
Its main mineralogical, chemical and physical features are summarized in Table 3 (data made available by the producer company) [15].
These results are very interesting since the blended mortars presented a significant reduction in the Portland cement consumption (up to 35%, by mass) and, consequently, a reduction in the greenhouse gas emissions.
To study the influence of ratio, k-factor, activity index and strength gain of raw powder on mechanical properties, data analysis was conducted using software SPSS.

The finding would also become a data base for further research.
This meant that the data variance value was at 100 µm2.
Therefore, the data variance to measure the surface roughness could be implied from the feed and speed.
These brought about the accurate designing treatment and appropriate for data analysis.
The S.D. was obtained from data collection of feed rate at 200 mm.

Energy consuming condition of thermal power unit is reflected by its historical operation data, but the amount of data and the number of energy consumption indices are large.
This can simplify the data, reveal the relationship among various variables, and extract the characteristics of the data[3].
Standardize original data.
The function of PCA is dimension reduction and feature extraction.
Structure the principal components after standardizing the data.

Comparison of multi-point injection with dry and flood cooling indicates reduction in cutting force and surface roughness while using different combinations of fluid injection.
Another investigation [2] shows that injecting MWF at rake face can be a beneficial in terms of reduction in tool wear, cutting force, cutting temperature and surface finish.
Khan et al. [4] showed considerable reduction in cutting zone temperature when vegetable oil as a MWF is injected at rake face.
Investigation by Itoigawa et al. [5] shows considerable reduction in specific cutting force compared to dry cutting when MQL nozzle is kept above cutting position.
Dynamometer was connected with the high frequency data acquisition system, which is then further connected with a computer.

Data driven techniques have been applied in many chemical processes.
This paper is used PCA and FDA to produce a lower-dimensionality, PCA is a dimensionality reduction technique which transforms correlated original multivariate data to a set of uncorrelated data [14].
Sampling time was used to collect the simulated data for the training and testing data is 3 minutes.
Let the original data set, where each row is a single sample of data set and each column is an observation.
Reduction order A reduced set of a smaller number ‘a’ (adata are good for fault detecting.

To analyze the data for the setup used during this study, a one dimensional model was used
assuming an infinite source of the dye.
The diffusion data thus obtained were validated with the theoretical values from the literature and also used as reference to compare with the diffusion results through the diatom stuck capillary.
The data shown here represent fluorescence intensity values taken every 30 s, over a time period of 20 minutes.
The continuous lines represent the theoretical curves and the symbols represent the experimental data.
The bottom curves of Fig. 4 show that the diffusion data fit quite well with the theoretical curves with diffusivity value of 3.1×10-11m 2s-1.
