With the further increased of nano SiO2 in the samples, the self-flow value decreased, a large number of air bubbles could not be excluded, resulting in the increase of the apparent porosity of the samples.
It is clear that the amount of Tridymite increased with addition of nano SiO2, but when the addition was 0.3wt%, the formation amount of Tridymite of the sample decreased to 30wt%.Because the small bubbles within the sample were too much that preventing the Tridymite grain growth.

Wind technology has grown substantially since its original use as a method to grind grains and will only continue to grow.
The number of the blades of a turbine has great impact on its performance.
Large number of rotor blades decreases the stability of the turbine.

The absorbances at 202 and 253 nm increasing linearly to the bilayer numbers for the film (given in the inset of Fig.1) show that the assembly is successful and uniform.
The close-packed clusters of SiW11Co-P2O7 nanoparticles with a mean grain size of ca. 26 nm are seen clearly in the film.
From the lower to the upper curves, the number of SiW11Co-P2O7 / PDDA bilayers is 0, 1, 2, 3 ·· 7 and 8, respectively.

The porosity of AZ31 Mg alloy foams corresponding to 30s to 180s are around 35.0%,72.0%, 57.2% while the pore number increases.
In Fig.2 it is found that eutectic and intermetallic compounds phase (SiO2, MgO, Al2O3 etc:) are segregated in grain boundaries.
If the content of the foaming agent is increased, and the incubation time and temperature are increased as well, the number of pores, pore size, and porosity of the foam will be increased consequently.

This is related to the increase number of grains after oxidation, resulting in a higher roughness and also increases Rsh.

Because of Nano TiN particle grain refining effect and dispersion strengthened effect, the strength and toughness of Nano TiN modified TiC-based CERMETS cutters were much more higher than those of ultra-fine Ti(C,N)-based CERMETS cutters[4],as a result tool tipping rarely occurred for Nano TiN modified TiC-based CERMETS cutter compared with the other one.

Introduction UHPC (Ultra High Performance Concretes) are ultra-high grade concretes with fine-grained macrostructure and high consistency.
This highly advanced and sophisticated material offers a number of interesting applications such as the production of facade panels, which promotes more abroad.
After the required number of 150 cycles, the testing samples were conditioned in the water 20 ± 2 ° C during 7 days.

Stress cloud of cutting district given stress value, the expansion rate of injury is increasing with the cycle number increments, when the cycle number reaches a permanent fatigue damage value, damage nuclear will also appear in the cutting region, the fibrosis degree of metal grain will reduce.

Electroplating craft. 140/170 grain size is selected according to the roughness and accuracy of workpiece ground.
It can be seen from table 3 that parallel degree, vertical degree gradually deteriorate along with the increasing of the ground workpiece number, while the ground Name or Items Specification or Parameters Wheel type BN140Pφ60×3.14T×13d Rotate speed of the wheel ns=21000~23000r/min , ds =φ60mm Workpiece and its surface to be ground Vane slot of cylinder Workpiece material cast iron Grinding allowance ap = 0.05mm Cooling mode Water cooling Machining cycle 30s surface roughness Rz is improved.
