Among them,the article expounded the principles, process and application status of the reduction of ammonia nitrogen removal, and give it a simple evaluation.
According to the in complete monitoring data, it is between 800 to 1600mg/Nm3, it doesn’t live up to the national standard GB4915-2004 and EU standard 2000/76/EC.
SCR is a developed practical technique of great potential, SCR can assure that the concentration of NOx in waste gas decreases to 100~200mg/Nm3.The effect of NO2 emission reduction can be as high as 80% to 90%, and unlike SNCR, its emission reduction performance won’t be affected by the mass shaping of cement kiln scale.
Discuss on the technology of NOX emission reduction in cement plant.

In terms
of economy and efficiency, the carbothermal reduction is the best choice due to introduction of
inexpensive starting materials [6].
Therefore, the carbothermal reduction process of oxide by carbon has been most widely used to industrial mass production.
In the Al(OH)3+SiO2+C mixture having the stoichiometric molar ratio of Al4SiC4, there were distinct two-step carbothermal reduction reactions; (i) carbothermal reduction of SiO2 between 1300 and 1600 o C, (ii) carbothermal reduction of Al2O3 above 1500 o C.
However, the XRD datum presents clear difference from that of Barczak, indicating the formation of highly oriented powder along the c-axis.
The XRD datum informs that the synthesized Al4SiC4 powder may have hexagonal plate-like morphology, which was confirmed by SEM observation (fig. 3.).

The data repair problem[8, 9] were introduced in many literature, such as exact repair, functional repair and exact repair of systematic parts, and can achieve a significant reduction in repairing.
The major concern of a storage system is that convincing the data owner that the server actually stores the data, i.e. data integrity check, such as provable data possession (PDP) [4] and proof of retrievability (PoR) [5].

In addition to local texture, statistical distributions of misorientations across grain
boundaries and of Σ grain boundaries have been derived from the individual grain orientation
data.
The ODF has been calculated, both from ACOM and XRD data, using the series expansion method with Lmax = 22.
After reverse rolling to 62% reduction.
The corresponding crystal orientation maps are shown on the right side. 313 314 Fig. 4 Statistical distributions of Σ grain boundaries calculated from ACOM data for reverse and cross rolled copper samples with an initial grain size of 100 µm (left) and 60 µm (right).
In addition to crystal orientation maps of the grain-specific microstructure and local texture (ODF), the misorientation data across grain boundaries are also available from ACOM.

Through the
simulated signal, it shows that the method can achieve noise reduction of non-stationary signals.
The proposed approach for noise reduction has been successfully applied to fault diagnosis of bearing signals.
The vibration acceleration data of bearings with faults are from the Case Western Reserve University [5].In the test instrument, the ball bearings are installed in a motor driven mechanical system, and are tested under several loads.
Application to Experimental Data.

Among all those methods, reduction remains the primary method for iron recovery from BFD.
Results and Discussion Analysis of the XRD data in Figure 1 observes a significant change in the phase structure of the sample with 30% BFD (30:70) during the reduction.
After reduction at 1000 °C (as signed 30:70 RD 1000 ºC), the intensity of the Fe₃O₄ and FeO peaks decreases, indicating the reduction of iron oxides, while a peak for metallic iron (Fe) appears.
XRD data in Figure 2 for four samples with different BFD:fine ore ratios (0:100, 10:90, 20:80, and 30:70) show a gradual reduction of iron oxides as the BFD ratio increases.
XRD data in Figure 3, analyzing samples with different BFD:fine ore ratios (0:100, 10:90, 20:80, and 30:70) reduced at 1100ºC, show a clear change in the phase structure.
