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.

In response to the mentioned problems revealed by the two models based on three or four particles, Yuan Wang and Yousif[5] et al. suggested that the fine particles are silted in the pores formed by the skeletal particles, resulting in the counted number of fine particles being less than the actual number, and proposed correction factors related to the compactness and particle size distribution.
The microscopic parameters such as porosity, pore volume, throat equivalent radius and coordination number are statistically analysed to obtain the real pore network model, and then the throat diameter is counted, and finally the stability of the soil interior is evaluated according to the obtained throat diameter, and the evaluation criteria are proposed. 2.
Based on the CSD curves obtained in the previous section, the percentage p of the throat larger than a certain particle size d is calculated to obtain the probability P(F) of the soil particles moving forward in the two critical states, and the number of particles that can pass through each layer can be obtained assuming that the skeletal particles are 10 layers The GSD of the particle size distribution curve, which eventually translates into fine particles, is shown in Figure 4.1.
Fig. 4.1 Prediction of Fine-grained GSD by CSD From the curves in Fig. 4.11, it can be seen that in the loosest state or in the tightest state, when the throat diameter is small, the predicted fines GSD curve is below the CSD curve, and as the throat diameter increases, the predicted fines GSD curve and the CSD curve have intersection points, indicating that the maximum throat diameter are larger than the maximum diameter of the fines, and when the fines GSD curve in the soil is on the predicted fines GSD curve left, the soil will undergo internal erosion and the soil will be internally unstable.
Conclusion In this paper, for the erosion mechanism of the suffusion research, in order to solve the existing suffusion test program can not be all-round dynamic monitoring tube welling development process, fine loose particles in the skeleton void transport process and loss law, first of all, the introduction and integration of transparent soil technology, plane laser-induced fluorescence image technology, build suffusion permeability visualization model test platform, get transparent soil samples of two-dimensional section collection; then With the help of Avzio software to transparent soil for three-dimensional reconstruction, to obtain the pore volume, pore surface area, pore equivalent radius, pore center of gravity, pore coordination number (that is, the number of connecting adjacent pores), throat area, throat equivalent radius, throat length, and throat connected with the location of the pore related parameters, the pore equivalent diameter and throat diameter distribution are

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.

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.
