The nameplate data method
According to the nameplate data, the efficiency is analyzed and calculated with losses analysis method.
(In the equations, the superscript “*” stands for nameplate data, and the subscript “mea” stands for measuring values.)
This part is composed of resistance measurement, temperature measurement, power analysis and data processing.
In addition, data processing is composed of two industry control computer and associated software, in which the storage of measurement data, the analysis of measurement results and the automatic producing and printing are accomplished.
The energy efficiency testing is based on Nameplate data method.

The measured data is treated with a data reduction scheme for noise and error elimination.
Data conditioning.
Data conditioning is divided into three main steps.
a) average of both measured contours b) smoothed average contour Fig. 1: Details of the data reduction process The calculated surface represents 99.3% of the average measured point cloud.
The finalized 2D surface mesh is than exported into MatLab [7] for the data smoothing procedure.

Representative data for the catalysts prepared in an air atmosphere are shown in Fig. 1.
Temperature programmed reduction using hydrogen indicates that there may be some mixed oxide formation in the calcined catalyst.
The catalysts were all similar by transmission electron microscopy, but subtle differences indicate that copper/zinc oxide solid solutions were formed and this is consistent with the evidence from temperature programmed reduction.

The data of the friction coefficient was recorded by a computer.
It is clear that the friction coefficient had various degree of reduction when the concentration of MoDTC was changed, which suggest that PAO containing proper concentration of additives showed better anti-friction ability than pure PAO and that containing PEG.
Fig. 3 The wear width of the GCr15 bearing steel under the lubrication of PAO and PAO containing different concentrations additive The mechanism of friction reduction for MoDTC has been widely discussed.

As the data shows, the AZ31B magnesium alloy thin strips obtained by Semi-solid rheocasting-rolling method have good rolling property, and the reduction rate can come to 57%, that opened the door for producing the termination product.
The reduction rate can come to 57% when hot rolled at the temperature of 360 degrees.

The corresponding EELS data (Figure 4) showed that SiOx enriched crust layer was completely removed allowing BARC been dissolved in solvent.
With this novel cleaning scheme a significant on-wafer defect reduction and total cleaning efficiency improvement have been observed.
By the addition of a simple dilute HF step and subsequent re-optimization of the wet step sequence and parameters, a significant reduction of on-wafer defects and yield improvement were achieved.

Carbothermal reaction has been extensively used since long for reduction of metallic oxides as well as for beneficiation of several minerals.
While there is the peak with highest intensity at 2θ = 31.78° corresponding to (101) plane in XRD JCPDS data file No. 35-1072.
The reason may be due to the influence of excess aluminum on the reduction of kaolin grog.

The solute concentration reduction rate caused by the vertical fractures is larger than the horizontal fractures by three or four orders of magnitude.
(2) Based on the statistical results of the experiment data from six groups of different fracture configurations, if the structure and permeability of the porous media remain unchanged, overall permeability and flow features of the fracture structure are significantly controlled by fracture configurations
(3) The solute concentration reduction rate caused by the vertical fractures is larger than the horizontal fractures by three or four orders of magnitude.
