DAMAS 2013 is the tenth in a series of biennial international conferences, which aim to bring together the expertise of scientists and engineers, in academia and industry in the field of damage assessment of structures.
The conference focuses on all research topics relevant to damage assessment of engineering structures and systems including theoretical and experimental studies, numerical simulations and signal processing of sensor measurements.
The DAMAS conference is now a well established major forum for discussion and dissemination of recent advances in damage monitoring, detection, assessment and quantification following the previous nine conferences held in Pescara (Italy, 1995), Sheffield (UK, 1997), Dublin (Ireland, 1999), Cardiff (UK, 2001), Southampton (UK, 2003), Gdansk (Poland, 2005), Torino (Italy, 2007), Beijing (China, 2009) and Oxford (UK, 2011).

Adopting the precast machinery with simple prefabricated process, small and flexible prefabricated factory shed and equipment investment, and U-shaped canal of precast concrete has the advantages of advanced technology and low cost [7].
At present, our country has put the lining to the canal seepage, as a kind of the main agricultural water-saving irrigation engineering measures.
In the channel engineering, by using concrete blocks (precast or cast-in-situ), most of the lining as optimal hydraulic section of U-shaped canal, and has been widely adopted.
Electronic control system is the whole core part of the production line, selected the Siemens S7-300 programmable controller (PLC), Germany's Siemens inverter, PILZ safety relay, Phoenix mechanical equipment for lightning protection devices, this configuration is very advanced in the same industry at home and abroad.

Compared with the surface morphology shown in Fig. 2, the carrier concentration in the area of the smooth terrace is regularly higher than that in the area grown by the advance of the macrosteps, and the edge of smooth terrace close to the macrosteps shows a lower carrier concentration resulting from the advance of the macrosteps.
It is assumed that the adsorbed impurities on the terraces are incorporated into the crystal by the advance of steps, because the distribution coefficient for nitrogen from Si melt to SiC crystal is greater than unity [4,9].

The distance between the supports is determined by the type of support generally, but it is got according to the length of each section of chute in conveyor and location of connecting block in jack on the chute baffle this time, for each advancing jack of the hydraulic support links with a section of chute in conveyor used in working field [2].
