During the sintering process for the ceramics of clay, the gas is formed at 400 oC by the volatilization of the sulfides, at 600 oC by escaping of water of crystallization, at 700 oC by the combustion of the organic compounds, at 850 oC by the reduction of the iron oxides, and at the above 1000 oC by the decarburization of the carbonates.
The bloating phenomenon in the ceramics usually occurs by one or more than two reactions enumerated above.[5] Particularly, the bloating of ceramics was known to be easily occurred when the gas generation by the reduction of the iron oxides and the liquid formation are appeared simultaneously.
The dotted line is the expected data.

Dimensionality Reduction using PCA
Principle Component Analysis (PCA) is proposed before shape model construction to compress the statistic by reducing its dimensionality, with acceptable information loss.
Background information is neither what we interest nor useful data.
In addition, iteration time also benefits from the dimensionality reduction after PCA.

The AA 6061-T6 tubes have been used to gather the data to determine the energy absorption of tube (external inversion).
· As comparison, a reduction of about 50-70% energy absorbed by annealed specimens had been recorded since annealing process relieved stress of the material and required less energy for the shaping process.
Furthermore, restructuring and non uniform grain size distribution on annealing process also contributes to the reduction of energy absorption.

The above data proved that BS was released from BS-MF microcapsules during the friction process and chemical adsorption process occured on the friction interface [5].

After that the work piece is given a heavy reduction with the aid of combined dies until it is shaped into a circular cylinder with cross-sectional diameter of 860 mm.
Since in the library of the Deform-2D/3D simulation system the data on this steel are absent, its mechanical characteristics were calculated individually based on the literature sources [2–4].
A straightforward calculation which is based on the axiomatic statement that the volume of a body under plastic deformation remains invariable, has shown that the reduction of the billet diameter from 962 mm (after upsetting) to 860 mm increases its length from 1230 mm (after upsetting) to 1376 mm.

To
date, many methods have been successfully applied to synthesize one-dimensional copper
nanostructure, such as electrochemical deposition copper into the hard template of polymeric ion
track membranes for copper nanowires [4] or porous anodic alumina for copper nanotubes [5], the
vacuum vapor deposition of copper nanorods on Mo grid [3] and the aqueous reduction route to
large scale copper nanowires[6], etc.
The calculated cell parameter is a = 3.6134 Å, which is close to the reported data within the experimental errors (JCPDS 4 - 836).

The statistical analyses of obtained data were performed with one-way ANOVA and the Tukey tests, both at 95% confidence intervals.
The higher the filler concentration, the higher the filler agglomeration, leading to the reduction in hardness [3].
This decrease is due mainly to: (i) the reduction in polymer volume fraction by the RHA-Si incorporation (dilution effect) and (ii) the restricted molecular mobility (or PMMA segmental motions) via the increased filler-polymer interaction.

Substituting corresponding data into equation(4)(5)(6), calculating respectively the stress intensity factor correction coefficient we get =1.367,=1.324,=1.049.
In general shallow seam the fracture length of main roof , which being inversely proportional to the load of overlaying rock seam, decrease gradually with the reduction of the horizontal compression.
The conclusion, that the fracture length of main roof decrease gradually with the reduction of the horizontal compression, explains the fracture length of main roof is generally short in shallow seams.

The Hhf reduction is also
characteristic for nanosized particles with magnetic

The analysis of the hysteresis loops with temperature increase shows evident narrowing, drop of coercive force from 320 to 46G, reduction of remanent saturation magnetization (Mr) in order of values and Mrs/Ms ratio from 0.38 to 0.091.
All these data being the indication of the increasing fraction of the superparamagnetic noninteracting particles at temperature rise newertheless mark the ferrimagnetic state of nanocomposite as a whole at room temperature.
