Therefore, reduction of CO2 emissions in the coal-fired power plants is an urgent priority.
With the application and development of computer simulation technology, we usually study the operating characteristics of complex systems with mathematical model, which is efficient, economic, comprehensive in access to data, abundant.
Fig.4 Dynamic response curve of the amount of coal test As is shown in figure4,when we reduce the amount of coal by 1% and 3%, furnace exit temperature, main steam flow, the refrigerant temperature and pressure in the superheater outlet all represent decreasing trend, and the reduction extent and transition time of the parameters are larger when the reduction of the coal is 3% than 1%.The reason is that ,when there is a stepped decrease of the coal amount, the combustion heat in the furnace reduces, which lead to a decrease of the flue gas capacity.
When the evaporation of the water wall decreases, both vapor pressure and heat absorption of the superheater (Qgr) reduce, heat of evaporation water (Qs) keep unchanged, which lead to a reduction in Qgr/Qs, so the refrigerant temperature in the superheater decreases.

To our knowledge, the catalytic efficiency of metallo-porphyrins in biomimetic systems is usually related to the metal-centered reduction potential [8].
From the point of HOMO–LUMO, the noteworthy bands shift of metallo-porphyrin was associated with the metal complexes reduction potential.
As the literature data reported that substitution of electron-withdrawing substituents in the porphyrin ring increases the redox potential and increases the catalytic activity in oxidation of isobutene [10].
However, to the same metal porpyrin complexes, the peripheral substituents in metalloporphyrin were a main factor that affects the HOMO–LUMO energy gap and consequently alter the reduction potential of the porphyrin in accordance with UV–vis studies [9].
Both from the UV-vis spectrum and the inchoate study of reduction potential, we conclude the S-S bond is likely to cleavage and serves as axial ligand for its central metal ion or other molecules.

Methylene blue is a water-soluble cationic dye molecule that is easily reduced to the colorless hydrogenated molecule (leuco-methylene blue, LMB) by a variety of reduction reagents, such as NaBH4, hydrazine, ascorbic acid, SCN- [5-8].
However, adding reduction reagents will bring the second pollution for water system.
The data point was taken at inetrval 120 mins, and the absorbance was measured with UV-vis spectrophotometer (TU-1901, China ) at 20 ℃.
Therefore, the reduction process of MB can be measured by UV-vis spectrometry.

In order to obtain well-mixed alloy catalysts, Cu-Pd nanoalloys were prepared by simultaneous reduction of Cu and Pd ions in the presence of Vulcan XC-72R as a support.
The simple Pd catalyst was prepared by chemical reduction method.
The EG electrooxidation was performed using two compartment cells to avoid re-reduction of oxidized products at a counter electrode.

Many castings, though more economical than similar parts made by other processes, have asignificant potential for further cost reduction by minor design modifications that lead tobetter product-process compatibility.
Table .1 ANOVASample Batch –I <10 A statistical analysis tool that separates the total variability found within a data set into two components: random and systematic factors.
The random factors do not have any statistical influence on the given data set, while the systematic factors do.
The ANOVA test is the initial step in identifying factors that are influencing a given data set.
After the ANOVA test is performed, the analyst is able to perform further analysis on the systematic factors that are statistically contributing to the data set's variabilityANOVA is the synthesis of several ideas and it is used for multiple purposes.

A brief analysis of the technical data provided by manufacturers of planetary speed reducers [5, 6] reveals backlash values between 5-12 minutes (0.083-0.2º) or even less.
However, as known from the scientific literature, a certain amount of the flank play is necessary for the proper operation of the planetary transmission.Eq. 3 and Eq. 4 show that a reduction of the angular play for the planet gears and the first planet carrier can be attained by increasing value of the corresponding transmission ratio so that a corresponding reduction of the backlash is achieved.
A look at the technical data provided by planetary transmission manufacturers reveal transmission ratios having values of i=15÷100 for two-stage planetary transmissions, achieving therefore a significant reduction of the angular play at the output shaft and confirming therefore, the previously made assertions.
Using the numerical data shown in this paper, the results are presented in Table 1 (for the first and second stage) The pitch radii R corresponding to the sun, planet and ring gears were computed as the product between the module and the number of teeth, as known from the literature.
An analysis of the numerical data shown in Table 1 confirms the theoretical assertions regarding the influence of the values of the transmission ratio over the angular play at the planetary transmission’s output shaft.

Milling is carried out until no further particle size reduction is observed.
The nanocomposites are cured according to the technical data sheet for 75 min at 160 °C and for 120 min at 180°C.
In fact, the additional shrinkage reduction can be explained by the formation of an interphase between filler and epoxy resin [6].
The comparison of the experimental results with the theoretical calculations reveals a higher reduction of the CTE than expected.
The presented results show the reduction of chemical and thermal shrinkage due to the integration of nanoparticles.
