There are three zones with different contrast in the SEM photograph, i.e. dark zone (around number 1), grey zone (around number 2) and white zone (around number 3), and the grey zone is between the dark zone and the white zone.
With carefully observations, the Ti3SiC2 grain size is between 5μm ~15μm and distributes uniformly in the Cu matrix.

The film surface is very smooth and compact, with grain size less than 100 nm.
Our platelet adhesion studies illustrate that the number of adhered platelets is smallest on sample #4, as shown in Fig. 3.
One can see that the number of platelets adhered onto the #4 film was markedly less than that for the others.

Gravel was continuous grading with grain size between 5mm~31.5mm.
After demoulding and numbering, wire brush was used to roughen both ends of samples, no less than 20mm protective mortar layers added at both ends were necessary.

However, alkalinity of concrete will be reduced with over-growth of n(H2O)/n(Na2O) which not only ruin the base enviroment but also increase the number of pores inside the concrete .

A large number micro-pores and micro-cracks originating from the adiabatic shear bands expanded, forming macroscopic cracks.
Some adiabatic shear bands extending upwards along penetration direction and a large number deformed structure were observed on the verge of penetration, as seen in Fig. 5 (b).

The laser beam power was fixed at 50W and the number of runs (superposition of tracks) varied on the sample.
Fig. 1: MEV of the starting material, thin graphite powder with 3 micrometers of average grain size.
As can seen in Table 1, the AISI M2 samples were irradiated with two different laser beam sweep speed values, whereas each one of them was irradiated a certain number of times or number of heating cycles, which are 3, 10 and 20 times.
Fig. 4 shows the dependence of the laser intensity and the number of irradiations of a sample covered by a graphite layer.

In this paper, it's simple and efficient of web page level extraction, with target of extracting the theme information, but not fine-grained data.
We get the number of its sibling nodes, set the serial number of its child node as 0, insert into the public XPath expression.
Firstly, define three variables, save the serial numbers of child nodes, the numbers of child nodes and step length values.
The initial value is the serial number of initial child node.
As show in table 1and table 2,the total number of data to be collected(#T) is 423.Since there are two formats about the information points of 2688 and joyo amazon shops, when the provided samples number(#N) is 2,the number of actual extracted information points(#E) is 366,in which 360 information points is correct(#C) ,and the average value of F is 75.23%,when the provided samples number is 3,the average recall value is 99.17%,the average precision value is 99.17% and the average value of F is 99.17%.

(5) Here Uij(r) corresponds to an indirect interaction of blisters with each other; Usurf(r) corresponds to the blister interaction with all surfaces of the layered structure (the interaction mechanism is the same), including the irradiated surface; Uph(r) corresponds to the interaction with lattice defects of the dislocation type and grain boundaries; and Upore(r) is the potential of the blister–pore interaction for porous materials.

The cell numbers were equal in each well (5 × 104/ml) at the beginning of each experiment.
However, upon incubation of the cells with some of the discs their numbers sig-nificantly changed in time and this is reflected by changes in numbers of adhering cells as macrophages must adhere in order to survive in in vitro conditions.
As can be seen from the photos that hydroxyapatite distribution is more dispersive, where some of the original surface slices grain is visible, and some distribution is obvious on the porous titanium surface without precalcified.
The number of cells on all specimen are less than that of standard sample (Control) cell number, no matter the surface modified or not.
Cell numbers cultivated 7 days are obviously higher than that of the cell number cultivated 3 days.
