The experiment data could fit the pseudo-first-order kinetics model very well.
NiWO 4 -ZnO-NRGO ternary nanocomposite as an efficient photocatalyst for degradation of methylene blue and reduction of 4-nitro phenol[J].

Due to the unbalanced rotation of the unit equipment, the vibration will greatly effects on the common characteristics of frame, so the common frame dynamic characteristics of marine turbine generator unit, the frame structure and vibration reduction design has very important practical significance.
Table 1 The natural frequency of the frame Step 1 2 3 4 5 6 7 8 9 10 Frequency（Hz） 45.5 51.1 54 65.5 74.4 84.2 86.5 88.1 97.6 98 With the data in table 1, the distribution of natural frequency of the turbine generator share frame has the characteristics of low and dense, which is determined by the characteristics of the spatial structure.

The enhancement on the extraction process caused by microwave is attributed to the disruption of the cell walls, reduction of the particle size and the enhancement on the mass transfer of the cell content to the solvent caused by the collapse of the bubbles produced by cavitations.
Multiple regression analysis of the experimental data yielded the following second-order polynomial stepwise equation: Y=3.31+2.510-3x1+0.23x2+0.041x3+0.033x1x2+0.17x1x3-0.040x2x3-0.2912-0.25x22-0.28x32 (2) An analysis of variance (ANOVA) procedure was used to analyze the model for significance and suitability, and a statistical summary was given in Table 2.

Using data from [2], we determine w0i as (31) where, , .
The relations allowing to predict change of the relative contact area under reduction of the loading of a joint of rough surfaces are obtained. 4.

The signal was exported to a computer for data acquisition.
Concentration of the sample was quantified based on reduction of CL intensity, ΔI = I0 - Is, where I0 and Is are CL signals peak height in the absence and presence of acetaminophen respectively. 2.4 Sample preparation Ten tablets of paracetamol were weighed and pulverized.

Compared with the traditional biological process, the process of partial nitrification/denitrification has several advantages including a reduction in the amount of oxygen consumed and the organic carbon used in denitrification (determined with methanol), an increase in the denitrification rate, and a lowering of the biomass in the anoxic stage [4,5].
The change of concentration for inflow and effluent of NH4+-N, total nitrogen (TN), COD is shown in table 1; the data is the average value of samples for 7 days.

As the amount of Pb2+ ions incorporated into the glass is the same as that of Zn2+ ions reduction from the glass, molar refraction (Rm) of glass as given by eq. 3 increases as the amount of Pb2+ content in glass increases.
Due to unavailable data for the intrinsic Rayleigh scattering loss for the aluminium fluoride glass, the intrinsic Rayleigh scattering loss of the fuse silica, as suggested in [9], was taken.

However, the quality of the SiC wafer needs further improvement implying the reduction of defect density.
Initial dT[℃] 30 50 100 150 XRD Mapping Data Max.

It passes the original data filter and the cut off frequency is 6Hz.
When the body reaches close to the vertical plane under the bar, in this study, among other changes of body posture, the reduction of the hip angle was most obviously, reaching 137.3°.

The AW and friction reduction properties of AlN as additives in base oil were evaluated with a four-ball machine under the following conditions: rotating rate, 1450 r/min; test duration, 30min; load, 392N; temperature, 25±2℃.
In order to investigate the factors and factors interaction, load-carrying capacity and anti-wear test results selected quadratic polynomial regression model for data fitting.
