Analysis of published data point to essential influence of polarizing signal duration on quality of the formed coating.
It was noted that the reduction in the pulse duration significantly reduces the porosity of the coatings, and as a result, their physical and chemical properties are improved.
The analysis of electrochemical data showed an increase of the polarization resistance and a corresponding reduction of the corrosion current for PEO coatings formed with the microsecond pulses, as compared to PEO coatings obtained by the millisecond pulses at the thyristor unit.

Diesel engine is used in the main drive system through the coupling which drives power to the worm gear and worm reduction gear, using a roller chain, and then driving to the embedded arm.
Taking into account that the engine speed is relatively high, so we should choose a reduction gear worm and worm.
In the process from mapping to the modeling, continuously changing to regulate data and improve data, finally we result in a more reasonable model.

Thus, it is significant to correctly account CO2 emission from ceramics industry in China for low-carbon economy development and GHGs emission reduction.
A series of activity data of these enterprises in 2012, such as, the kind of fossil fuel, the consumption amount of fossil fuel, the lower calorific value of the fuel, the content of CaCO3 and MgCO3 in the feed, the utilization efficiency of the feed and the amount of feed, etc., were gained from these enterprises directly.

Discharge method was stand for 1 h in different stated temperature, and then discharged in constant current at 1C until the voltage dropped to cutoff voltage 2 V, calculated released capacity; ③ Developing experimental program : In this experiment, 25 ℃ was set as temperature test basis points , firstly low-temperature performance testing was conducted , starting from 25 ℃ to -40 ℃, made 0 ℃, -10 ℃, -20 ℃, -40 ℃ as visits point respectively, the rate of temperature changing is 1 ℃ / min, at each temperature test point , the test batteries were shelved for 24 h before temperature performance test under the temperature point ; then high temperature performance test battery was conducted , resume the high and low temperature test chamber to 25 ℃, in order to eliminate produced by low-temperature impact test , and the data measured was used as a reference point for high-temperature testing , followed by a high-temperature performance of the test battery , started from 25 ℃ to 60 ℃, discharge
capacities of different lithium- ion batteries were investigated under 1C; ④ When the high and low temperature test chamber reached the set temperature stably, put a single experimental tank lithium-ion battery which standard voltage is 3.2 V after standing for 1 day in the chamber insulating for 1 h, made it reach to thermal equilibrium ; ⑤ Switch on discharge circuit to start the experiment , did not shut off the discharge circuit during the experiment to measure the actual voltage ; ⑥ When the battery discharged to a cutoff voltage of 2.0 V, stopped the discharge , analyzed and processed the data .
Fig. 1 The discharge capacity of Batteries Fig. 2 The discharge curve of Batteries at different temperatures at different temperatures Fig. 3 The discharge curve of Batteries at -20℃ Fig. 4 The discharge curve of Batteries at -40℃ From Fig.1 and Fig.2, it can be seen that the discharge capacity of nano LiFePO4 Power Batteries would reduce with the declining of temperature, because under the condition of low temperature, the concentration of battery electrolyte increases, which leads to a slow rate of lithium ion deintercalated from anode materials, In addition, as the internal resistance of the battery becomes larger, discharge cut-off voltage of the lithium-ion battery is reached In advance, resulting the decrease of its discharge capacity, as well as the reduction in discharge efficiency[3,4].
Physical characteristics of the electrode materials of lithium batteries will decay irreversibly under the condition of high temperature, and the reaction of electrode materials will weaken, so the decrease of its discharge capacity, as well as the reduction in discharge efficiency.

Practice: the open-loop system , an appropriate amplitude step signal output by the controller, so that the pump speed is increased to a certain extent , and then record the change in water pressure process, in accordance with the input and output data to identify.
Fuzzy PID control system simulation Simulation, the system can use the oscilloscope output data can be stored in the MATLAB workspace variable specified curve will be output to a separate window , and then use the drawing commands in the MATLAB environment .
Fuzzy PID controller, the the PID three parameters to achieve line adjustment control system phase jump response curve overshoot , the system greatly shorten the transition time, reduction of the oscillation frequency, the system showed better stability.
The simulation results show that the fuzzy PID controller parameter adaptive, control system response speed, overshoot to be reduced , the transition time is greatly reduced, reduction in the number of oscillations, stability and strong robustness, these are simply the PID control is difficult to achieve.

The data are shown in the following Table 1.
The influent data of the reactor [mg/L] Items OIL LAS CODcr NH3-N TN TP SS range 60-110 4-13 600~1400 15~45 28~56 3~10 50~170 1.2 Materials and method Materials: membrane modules: PVDF (polyvinylidene fluoride).
Data in Fig.3 illustrates the effluent COD removal ratio.
After all, the stable data of effluent's COD is supported by the active sludge and the membrane[3].Because of the blocking of the sewer, the raw wastewater was sticky once a time.
Upon analysis, there might be two reasons: one was that sludge recirculation ratio was on the low side, so there might be shorter time for anaerobic digestion, so as to denitrification; the other reason was that there was overflow accident happened in the experiment and it leaded to the reduction of the sludge which reflected on the reduction of the nitrobacteria and denitrifying bacteria which played a role on ammonia nitrogene.

There are three ADS-B data link systems.
However, 1090ES ADS-B is the only data link system recommended by ICAO[1].
Received Data Model 1090ES ADS-B signal contains 112 binary symbols.
The transmitted bit stream b is a packet consisting of a preamble p=[1,0,1,0,0,0,0,1,0,1,0,0,0,0,0,0] which is followed by the encoded data bits.
Then the data is sliced in segments of 80 samples (4μs), on which an SVD is performed.

Specific features of dispersed magnesium application in both processes, considering magnesium ability to react chemically with oxygen, nitrogen and some oxides, as well as advisability of magnesium alloys usage instead of primary metal based on the authors' personal experience and data from literature are examined below.
Table 1 shows by no means all the data found in literature sources, dedicated to study of local features of magnesium particles ignition and burning in the atmosphere of oxygen and air.
Table 1 also shows data on magnesium alloys composition effect on their fire and explosion safety.
Taking into consideration these data, as well as paper [20], concentration of 9-10% Al in alloy could be recommended as optimal.
According to data [20] fine magnesium ignites in nitrogen atmosphere, containing over 2% of O2 as well.

We must bear in mind the important fact, when we use for market analysis in addition to official statistical data and databases of Mosgorbti updated on a specific date, also real estate assessments.
Characteristic data of domestic and international real estate brokerage and consulting agencies in the area of office premises is their inconsistencies and the lack of a unified approach, associated with differences in databases used by different technique of the account of objects and their class definitions.
Another sources offer higher data: GVA Sawyer (1, 1 million m2), Jones Lange La Salle (1.5 million m2), Colliers International (1,4 million m2).
This is evidenced by the data of Mosgorbti.
Simultaneously with the reduction of input volumes in 2012 the proposal of offices inside the Garden ring in 2012 decreased by 31% (Business Partner) and, most importantly, in the CAD the share of vacant space has decreased: up to 15.8 % (class A) and 6.5 % (class C) [data IRN].
