Through a large number of experimental data, this paper verified the feasibility and the effectiveness of the proposed approach to the unbalance fault diagnosis.
Data processing From the above experimental data we concluded, we can get ten special clinic parameters we want with the help of data processing software.
The steps of experimental data processing: (1) Entering the interface of data processing, choosing characteristic parameters for diagnosing
(2) Firstly selecting the reference data, i.e. no loading data, Reference data is a kind of point data without load, it will compare with point data adding some load, thus obtaining the DI, DR, and other related parameters.

Iannuzzi[7-9] had used the split cell technique, EIS, polarization curves, and adsorption isotherms methods to study the mechanisms of corrosion inhibition of AA2024-T3 by vanadates, and find that the clear metavanadate solutions(contain monovanadate (V1), divanadate (V2), tetravanadate (V4) and pentavanadate (V5) species [10-12]) were shown to be good inhibitors of the oxygen reduction reaction(ORR) by adsorbing on the surface and blocking sites rather than by a reduction process, and the main corrosion inhibition composition is metavanadate(V1) .
It may because that the adsorption activation energy of SO was significantly lower than the activation energy of oxidation-reduction reaction which sodium vanadate participates in.
The second is that the oxidation-reduction reaction which sodium vanadate participates in is increased with the increase of the temperature.

Coarsening of second phase particles involves a reduction of the total free energy of the system.
In fluids, the tendency for larger particles to grow at the expense of smaller ones is driven by the reduction of surface energy.
Reduction of elastic energy promotes particle alignment along elastically soft directions and changes of morphology as the precipitate volume increases.
In addition according to several authors, reduction of elastic energy produces the splitting of large particles that reach a critical size [2,3].
The lattice parameter mismatch (d = ap-ap/am, m=matrix, p=particle) normally used for characterization of a Ni alloy can be readily derived from the data in Fig. 2d as shown elsewhere [13].

These unwanted noise signals may result in the incorrect switching of digital circuits, leading to false interpretation of important data at the output.
This improvement in speed at high temperatures is accounted to the reduction of threshold voltage of the complementary pair and higher on state saturation current through the channel at high temperatures [2].
Thus, for applications requiring operation at high temperatures, a similar speed performance can be attained by 4H-SIC CJFET technology at a much lower supply voltage, resulting in significant reduction in static power dissipation and subsequent increase in efficiency.
This further reduction in power can be easily achieved by scaling the supply voltage down to 1 V.
From the results shown in the table it is evident that even after supply voltage reduction to 1 V, the noise margins and metastability in CJFET logic inverter are comparable to those of Si and strained Si based CMOS inverters, operating at room temperature [6].

The VFAs are produced from biodegradation of non-rubber such as protein, carbohydrate etc. [7] Recently, wet scrubber with packing media has been introduced to remove VFAs contained in exhausted-hot gas from rubber oven for malodor reduction in STR 20 factory.
This naturally leads to a reduction of the wet scrubber efficiency.
Information from this research can be useful for further development of effective wet scrubber and the bio-wet scrubber for malodor reduction by bacterial attachment in packing media in STR 20 factory.
No data of malodor removal efficiency were reported from the factory.
Information from this research is useful for development of efficiency of wet scrubber in the future about bio-wet scrubber for malodor reduction by bacterial attachment in packing media in STR 20 factory.

Mechanical alloying has led to a reduction in peak intensities and broadening of the diffraction peaks as the milling time duration was extended.
Generally, larger amount of defects were introduced to the milled sample when subjected to high energy impact, thus causing the peak broadening and reduction in crystallite size as the milling time increased.
All the XRD diffraction patterns revealed the formation of single-phase SrTiO3-type cubic (Pm-3m) perovskite structure, which corresponded to 98-006-6631 of the International Center Diffraction Data (ICDD) standard.
For microstructural analysis, a reduction in grain size was noticed as the milling time was increased.
The reduction in grain size resulted in the decrease in the dielectric constant as the milling time was increased.

To characterize the clay it were used data from the literature, which indicated a particle size of 200 mesh, corresponding to 74 μm value close to that obtained for the powder of stone São Tomé used.
This effect may be due to the reduction of active sites caused by the addition of quartzite with a consequent reduction of interstitial water.
This fact can be explained by the reduction of water allocation sites, which generates a higher packing of the particles, coupled with a higher drying rate characteristic of microwave drying.
Also, the composite showed interesting features like the possibility of reduction of structural defects in the product.

There is a reduction in transmittance of the composites with the increasing weight percentage of the BC as there is increase in the fibrous network density which causes the reduction.
The transparency of as prepared and dried sample was reduced with increasing BC content which corresponds to transmittance data.
As it is evident from fig 6, that fibres are randomly oriented which may be the cause for reduction in the Young’s Modulus and tensile strength.
This reduction may also be due to high porosity or poor blending between BC and PMMA.
