Each time, noise levels were observed for 30mins continuously and the average value was achieved by the acquired data.
So Q14 is much wider than Q1, noise reduction is completely opposite；and Q6 and Q9 have the same width, but noise reduction is different.
We can see from the table 1 that the Q1 noise reduction effect is best, Q4, Q5, Q13, Q7 are better，Q11 is worst.

Arithmetic average, wavelet noise reduction and low-pass filter combination of data processing is used to overcome the very low SNR.
The computer obtains many sets of data of all points, and then it processes the data to obtain the temperature value.
After averaging, the data are processed using wavelet modulus maxima reconstruction noise reduction filter.

System testing data is basically consistent with the reference data.

With slenderness ratio changing, the variations of experimental data such as axial strain, lateral deflection at mid-height, ultimate bearing capacity, and peak strain were comparatively analyzed.
The ultimate load reduction factor is obtained by regression analysis based on the experimental results of Larch Glulam short columns.
Comparing curves in Fig. 3 with data in Table 2, the conclusions can be made as follows: (1) The trend of the lateral and vertical strain of each specimen was almost the same, so the failure process is divided into three phases [11,13]: elastic phase, plastic phase and failure phase.
Combining the curves in Fig. 4 and the data in Table 2, the conclusions can be made as follows: (1) As can be seen from a) and b) in Fig. 4: 1) Small lateral deflection appears at the preliminary stage of loading, which is caused by physical eccentricity and defects of columns; 2) At the initial loading, specimens suffer mainly compression stress, and lateral deflection at mid-height is almost zero.
The formula of the ultimate load reduction factor for long Larch Glulam columns is obtained by nonlinear fitting, which is: .

The effect of reduction of temperature was studied, by CO gas at 800, 900, 1000, 1050 °C, for 3hours reduction time.
At lower temperatures iron had lower degree of reduction, and phosphorus was not reduced at all.
According to the data provided in Table 3 for the analysis shown in Fig. 2 it can be observed that in CO gas atmosphere at temperature of 800 ° C and for 3 hours holding time there was no reduction of iron to metal in the oolite structure (there was no bright white metal phase found).
Only after reduction the preoxidized ore acquired magnetic properties.

Moreover, the reduction temperature of the NSR catalyst decrease first and then increase with the increase of calcination heating rate, and the reduction temperature of as-received NSR catalyst is the lowest as the reduction temperature is 6 °C/min, that is its reduction performance is the optimal.
The specific surface area and pore size distribution of the catalyst were performed by nitrogen adsorption data (NOVA2000, Kangta, USA).
Moreover, the catalyst with the calcination heating rates of 6 °C/min obtains the minimum reduction temperature (459.2 °C), indicating that the catalyst has the best low temperature reduction performance.

However, for these ideals as the above, the testing data on surface structure of composite materials need to manage and analyze in some elementary, in other words, that are the testing data of mathematical or statistical models on the surface structures.
More concretely, due to the data being excessively complex, the data must be in a great extent contracted and purified to satisfy many applying objects.
Furthermore，it was indeed pointed that the effects of these data reduction modes are vary valid and significant especially in the updating age that composite material systems link closely with information network and large data, however, it is pity in some extent that there are few references on these topics at present.
At last, it should be pointed in data analysis for this paper that the element model, the picking indicator and the simulation on data are very important.

This pattern is supporting the XRD data analysis that the process will be significantly inactive after 60 minutes reduction.
This also corresponds with XRD data mentioned before.

In this study, to evaluate the reduction effects of urban heat reduction of water-retentive pavement, surface temperature of pavement, air temperature, wind speed and albedo were measured for 3 years(2008~2010, summer period).
Experimental results indicated that water-retentive was effective to reduction of air temperature by decreasing of surface temperature of pavement compare to other pavements.
This increasing of impervious area was caused the urban dryness and destruction of water cycle and heat cycle by reduction of evaporation that is reduced from 42% in 1962 to 25% in 2002 [7].
In this paper, effect of urban heat reduction of water-retentive pavement was studied compare with existing rigid pavement.

Up to now, interfacial instabilities in aluminium reduction cells have attracted much attention since they might cause short circuit and influence greatly on the temperature distribution and reduction of energy consumption.
Besides, a NI data acquisition board PCI6284 is applied to collect raw signals from the sensors, which has 32 analog input channels, a resolution of 18 bit and a sampling rate of 500kSps, this enables a sampling rate of up to 15 kSps per channel if 32 analog input channels are utilized simultaneously.
