On the other hand, the surface roughness data at
different planetary gear ratio and polishing time have been measured.
When n0 is too small, part of the ring is destructed at certain position (Figure (a)); (2) Along with the reduction of n0, S shape of the foreside glide lamella of the abrasive flow becomes unobvious gradually, especially in the first quadrant, where the foreside has been in the middle state between the flow and dispersion (Figure (b)); (3) In the upper-half circle, the effect of gravity is evident because of the reduction of the centrifugal force.

According to this phenomenon, this paper compared the two different bearing floating slab noise data, studied their dynamic characteristics under train loads.
As the lines with a large number of steel spring FST structure are in operation, there are low frequency noise like "gu long gu long" in the carriage when the train runs over the steel spring floating slab area, which affects passenger’s comfort, and also cause the more and more attention of researchers[1]-[3]. 2 Noise testing data in carriage when train runs over different track area Aiming at the problem, noise data from different floating slab areas was measured in the carriage.
One group of data (Fig.1-Fig.3) is the train run from common slab track to steel spring FST area.
The data from Fig.6 shows: noise in the vehicle rises unapparent when the train moves over high damp floating slab.
The test data in Fig.5 verified this method is feasible.

VIBE models the background using data samples from previous frames.
We can build the similarity degree as the data term; build the spatial information as the smooth term.
The data term is the main proposed part of this paper.
Here we straight give the data terms: Where stands the coefficient of proportionality of the data terms and smooth terms, and Where the mean value of is, is the variance of.
This data set has the advantage of ground truth for all frames through it is a synthetic.

Results and discussion
AFM and SEM data.
According to SEM data, an etching speed was about 6.2 nm/s.
Comparison of the AFM and SEM data shows that the size and concentration of pores on the skin-layer surface are quite different from those in the underlying porous layer.
IR spectroscopy data.
Based on the data obtained, it can be assumed that at first, a part of the surface area of as-formed PS layer was partially passivated with hydrogen and it contained a lot of dangling bonds, which played a role of nonradiative recombination centers.

The information techniques being used in product innovation include PDM (product data management), CAD (Computer Aided Design) or data mining et al. [9].
But most data set comes from a certain business, knowledge acquired from which is only reflected a part of affairs, most of the product innovation is based on incomplete data.
Intelligent Knowledge (IK) for Innovation 3.1 Creation Process of IK As mentioned above, there are many data sources in the information age from which data mining discovered lots of knowledge.
Primary knowledge is knowledge from data mining but only a part of a given knowledge meets interest of human beings.

The virtual city 3D model needs a lot of data.
Because only graphic data can be stored in AutoCAD,the method pays attention to separating graphics data and the graphic datain the data collection.
Set up texture lab Acquisition and processing of texture data.There are two main types of texture data acquisition method.
Graphics processing operations mainly includes: distortion correction, removing the mask, image enhancement, and data redundancy reduction.
Read data via automatic programming, batch processing of the model and reduce the workload and the amount of data that scene.

Optimization of the drying process (reduction of process time and energy expenditure) is crucial for the ceramist industry.
The numerical simulation technology to reproduce the experiments is recent, but it has several advantages over the experimental works carried out in laboratories and pilot plants, for examples: · At various instant of time, it is possible to see gradients of moisture and temperature inside the solid; · Heat and mass fluxes can be quantified over time and space; · The sensitivity to small changes of the process parameters is greater, eliminating uncertainties of experimental tests; · The predictive modeling capability allows the design and optimization of dryers or drying processes without necessarily having to construct a prototype, thus, reducing costs; · There is no limitation on the drying conditions or safety concerns; · In numerical simulation the study can be done in the real scale, without the necessity of reduction of scale.
The optimization of existing drying technologies or the developing of new technologies is focused on two aspects: the reduction of energy expenditure and the time required to completely dry the product while maintaining the quality of itself.
This phenomenon approaches the clay particles and other components, causing volumetric retraction, that is, the reduction in size of the part, which can vary from 4 to 10%, depending on the initial moisture of the part.
The present article is part of a research that aims to simulate, and compare experimental data, a heat and mass transfer in the drying process of bricks involving the product in an external environment, which in this case is a drying oven.

The mechanical results revealed a systematic reduction of the maximum compressive strength when the volume of Ichu fibers in the mortar mixtures was increased.
From the data found, it was possible to verify a notable reduction in the values of maximum resistance to compression when increasing the volumetric fraction of Ichu fibers.
The other mortars R showed a gradual reduction in the modulus of elasticity with the increase in volume of added fibers.
