It strengthens the binding among coal grains so that the compressive strength of formed coke is raised highly.
The particle size of pulverized coal are divided into five levels: <0.28mm; 0.28-0.63mm; 0.63-1.25mm; 1.25-2.5mm; 2.5-5.0mm，which in turn number 1~5.

The relationship between crack length and cycling number in semi logy coordinates is shown in Fig. 5.
Cyclic stress-strain response and low-cycle fatigue damage in ultrafine grained copper.

The studies on bio-mediated soil improvement have been carried out by a number of researchers including Dejong et al. [1], Harkes et al. [2], and Ivanov and Chu [3], and Qian et al. [4] etc.

It can be seen that the specimen exhibits the poor grain connection in some parts.
The critical temperature of MgB2/Al tape obtained from anhydrous B2O3 was measured as 37.4 K Acknowledgements This work has been supported by DPT (the State Planning Organization of Turkey) under project number 2001K120590.

Deflection of  base surface significantly reduced and the number of  roadway’s left side decreased 42 (0.1mm) after large-stone asphalt mixesl upper base has been constructed.

Currently, there are 14 raw material medicine production approval numbers for dipyrone production and 12 manufacturers, including Shandong XinHua pharmaceutical factory, Hebei Ji Heng Group Pharmaceutical Co., Ltd., Wuhan Department Store drug Pharmaceutical Co., td., Shanghai Wuzhou Pharmaceutical Co., Ltd..
The grain size of the product is small, color is not qualified

Introduction Piezoelectric lead zirconate titanate (PZT) ceramic material has been widely used for transducer applications, due to its excellent piezoelectric properties, and was a candidate in a number of recent investigations [1, 2].
There was no change in the grain size.

The intrinsic brittleness of Ti(C,N) can be improved by grain refinement so as to promoting the further development and application of Ti(C,N); nano-TiO2 as a new photo catalyst, anti-UV agents, photoelectric effect agents, shows broad application prospect in the areas of anti-bacterial defense, anti-fouling, anti-aging and car painting,.
After stopping discharging and removing the upper electrode, the upper electrode and lower Electrode surface is coated by a large number of visible gold powder which shows that a chemical reaction occurs(as shown in Fig.4).

The 18 mm × 5 mm faces were aluminized by the process described above, while the other faces were polished using abrasive paper with #800 grain.
Numbered white circles in Fig.2a indicate measurement points of EDS analysis.
