Present state of dust reduction in blasting demolition According to related data from scientific research, effective measures against blasting dust are still not found at present.
The effect of dust reduction is good
The effect of dust reduction is satisfactory
The effect of dust reduction is very good.
Obviously, dust reduction by foaming is better than dust reduction by watering.

NO reduction is up to 50%.
It mainly consists of five parts, that is, the coal pulverizing system, the combustion system, the data acquisition and control system, the compressed air cooling system and the online flue gas sampling analysis system.
The data collection and controlling system is composed of the corresponding software and hardware.
It is used for collecting, recording and processing data.
In the experiment, each experimental cases is conducted six times at the same condition, the data in figure 2 and the following figure is the average data of the six times.

Electrochemical Reduction of AQ27DS in Aqueous Solution César A.C.
This reduction can be regarded as electron transfer followed by protonation.
The values obtained complemented by data taken from the literature [2,3] enabled the mean value of δ to be calculated to be 5.0 µm, under the particular stirring conditions employed. 4.
The reduction was found to occur at a half wave potential of -0.25 V vs.
Only a single reduction peak was observed, even though potentials down to -1.4 V vs.

Also, a data logger and computer were used to obtain data.
in internal forces after the final fracture of the reinforced specimen at the maximum strength as the net reinforcement effect caused by transparent composite panels and that was applied to produce partial reduction coefficients.
The strength lowering of transparent composite panels can be reflected as a partial reduction coefficient in reinforcement designs using transparent composite panels.
Thus, it is regarded that if the partial reduction coefficient is applied by 0.8 in a reinforcement design, a safe design can be established.
(2) It was regarded that if the partial reduction coefficient was applied by 0.8, which was determined based on the results of the bending reinforcement performance evaluation, in a reinforcement design, a safe design can be established.

Through study on the regulation of tensile strength and reduction of area after artificial aging and natural aging for SWRH82B wire rod, indicate that the tensile strength of wire rod unchanged through artificial aging or natural aging treatment while the reduction of area changes significantly the reduction of area is effected by aging temperature and aging time.
The initial reduction of area of SWRH82B wire rod is usually lower after hot rolling, but the reduction of area has aging phenomenon[4]. 
The Table 1 data shows: with the increase of holding temperature of artificial aging, the Z value of change rate was significantly increased, that means the reduction of area of wire rod has a significant aging phenomenon.
The variation trend of the tensile strength (Rm) and the reduction of area (Z) of the SWRH82B wire rod with natural aging shows in Table 2. 
The reduction of area of increasing rate (Δ) listed in Table 2.

The study underscores a reliable approach to noise reduction and insight into concentration-dependent heat transfer dynamics.
This application finds utility in diverse fields like signal processing, data analysis, and mathematical modeling, enhancing the accuracy of information extracted from noisy functions.
Methodology Noise reduction.
Results and Discussion Noise reduction.
In summary, the proposed methodology offers an approach for noise reduction in mathematical functions, with potential applications in areas such as signal processing, data analysis, and mathematical modeling.

Complicated reponse of structures from limited sets of data can be expanded to full field data using a unique expansion technique first proposed by Chipman[3] and extended by Pingle [4] to obtain not only full field displacement information but also extended to provide full field strain data.
Expansion of real-time operating data is needed for the structure assessment.
· Measured data at the test points is obtained (either operating data or prescribed input)
· The measured data at ADOF is expanded to NDOF using [Tu]
Only limited cases have been studied thus far but measured data is currently being evaulated and will be the subject of future work.

First, the core goal of rough set is the effective classification of the monitored objects, and to obtain the knowledge contained in the large amounts of data.
Third, the rough set can find the association rules between indicators and results from a large amount of data.
IF are two attribute sets in addition that is contained in , , so is a reduction of , All attribute reduction sets of written for can be deduced from different attribute reductions.
Indicators are given in table 1, establish the decisive information system .At present, according to rough set theory, the method of attribute reduction is based on discernibility matrix, the attribute reduction algorithm of frequency reduction, genetic algorithm reduction, etc. this paper mainly refer to literature function —redu ( ), make reduction to decisive information system, Then we may got reduction of decisive information .
Design of MATLAB simulation tool box of rough set data analysis system, J.

Furthermore, a complete data acquisition system was utilized into the field tests, and all pressure values are measured and recorded by the system, which contributes to the analysis and optimization on the working performance of the oscillation tool with an amplifier.
ST004400 Pressure 0～70Bar Input 10V～24V Output 4～20mA Temperature (˚C) -40～+125 Precision (%) 0.5 Field test In order to monitor and measure the variation of pressure pulse with the pumped flow rate, there are totally 5 groups of flow rates are pumped into the oscillation tool with a fluidic amplifier, and all of the pressure pulse values are simultaneously obtained by the data acquisition system.
In the meantime, all the obtained pressure values are timely grasped and recorded by the data acquisition system while the pumped flow rate is ranging from 5L/s to 18L/s.
The pressure variation of monitored cross-section of the oscillation tool with pumped flow rate is obtained by data acquisition system, which directly implies the work performance and status of the friction reduction tool with a fluidic amplifier.
As shown in Fig 2, the pumped flow rate has an influence on the vibration frequency of friction reduction tool with a fluidic amplifier.

The experimental data show that: The yield ratio of the Q460C was found to increase with the elongation at break A and the reduction of area Z decreasing while the plasticity and toughness decrease as the testing temperature drops.
The Comparison of Strength Index of Experimental Data with Parameter Fitting.
But it is great deviated from fitting data below -20°C.
