Image analysis
Number of fibers and cross-section area occupied by fibers were determined with ImageJ software.
Average number of six cross sections of a brick with 3cm long fibers is 272 fibers and they cover 6.71% area of a brick cross section.
In case of 2cm long fibers, average number of fibers for a cross section is 280 fibers and they occupy 6.46% area of a brick cross section.
Number of fibers and area occupied by fibers in a cross section is shown in Fig. 6c.
Number of fibers in case of 2cm length fibers is slightly higher due to small length of fibers.

The total number of aggregated water molecules is proportional to the cluster length.
As a hypothesis, we assume that the deviations cause is changes in the molecules combination geometry into clusters and the cluster different coordination number.
Instead, Pmax is determined by the explosion maximum temperature and the moles additional number formation in explosion products at a system constant volume.
We explained the limited solubility as the all water molecules aggregation by the solute molecules certain number.

Introduction
Large numbers of researches and engineering applications show that carboxylic-vinyl copolymer (PC) has not only excellent dispersibility and holding dispersibility, but also little alkali, chloride ion and good mechanical properties.
HC is advantage to disperse cement particles and increase the number of active hydrating points in initial several minutes.
From fig. b, the CH, which is hexagonal flake, is well crystallized, and the structure of cement paste is close-grained.

Introduction
The titanium dioxide (TiO2) has been considered as a promising material recently which has a large number of applications such as the photocatalyst [1] and diluted magnetic semiconductor (DMS) devices [2-4] in spintronics.
The mean grain sizes of the samples were evaluated by Scherrer’s formula with the A (101) reflection and the results are summarized in Figure 2.
This makes us interpret the decrease of Hc when the temperature falls: The free carriers and defects are produced by heat exciting to a large degree, and the number of them increases exponentially with temperature (N ∝ e-D / kB).

Since then, this effect has been studied many times
in different materials, and it is generally recognized that the difference, between the forward and
the reverse mechanical responses, can be attributed to the interaction of the dislocations with the
microstructure, mainly precipitates, grain boundaries or elastic second phase particles such as those
found in metal matrix composites or intermetallics [2, 3].
will increase the number of stored dislocation and thus the internal stress.
Moreover, in the case of the peak aged material, it has been shown that the precipitates are still shearable by the dislocations [5] and thus the number of dislocation loops formed around the precipitates is very low.

Introduction
Ionic Soil Stabilizer(referred to as ISS) is a strong ion by a combination of several water-soluble chemical substance, applied to clay content in the grain group of more than 25% of all soil types.

In the dynamic triaxial tests, when the confining pressure increases, due to closer contact between soil particles, pore reduction, so wave energy loss in the dissemination process will be reduced, the corresponding number of parameters characterize the energy loss is also damping ratio reduced accordingly.

Experimental
The concrete was mixed by 42.5 ordinary Portland cement, continuous grading crushed stone with grain size 5-20 mm, natural river sand with fineness modulus 3.3, water reducer, steel fiber and polypropylene fiber.
With the increase of freeze-thaw number, the hybrid fiber concrete test specimen of the flexural strength decreases.
Fig. 2 Changes of flexural strength of FHPC with mass content of polypropylene fiber and fraction of steel fiber by volume On the basis of the steel fiber volume rate is 1%, with the increase of content of the polypropylene, the specimens can achieve the freeze-thaw number are on the rise.

Efficiency Let k be the number of attributes with respect to identity ID. p is bilinear pairing in G1. sk denotes private key.
In addition, the number of group elements in a private key or in a signature grows linearly with the size of the identity.
