We investigated the dynamics of the passage for a polymer chain through a nanopore in the absence of any external driving force with Weeks-Chandler-Andersen potential in two-dimensional simulations, in particular, focused our attention on the scaling law of the mean translocation time. We found that the effect of hydrodynamic interactions is the major factor in determining the scaling exponents with increasing pore size. The scaling close to N1＋2v was observed when the hydrodynamic interactions were screened in the cases of small pore sizes, while the scaling close to N3v was obtained when the hydrodynamic interactions were present in the cases of large pore sizes.

Hard coal mining in the German Ruhr district has a tradition of more than 200 years. Starting in the south near the river Ruhr with mining of seams near to the surface, mining wandered to the north with coal seams deeper and deeper. In the same way all environmental effects of mining wandered from south to north, as there are abandoned mining sites, contaminated areas, burning mining dumps, subsided areas and gas accesses at day ground. This all happened in a very high populated area with more than four million inhabitants. Therefore Germany has a long tradition in solving environmental problems of mining activities. The very good interaction of mine authority, mining companies and the mine workers’ union is the main reason why the problems of decreasing mining activities in Germany were solved without economic, environmental or social hazards.

A substrate with Ni/Ti/Si structure was used to grow vertical carbon nanotubes(CNTs) with a graphite film over CNT tops by thermal chemical vapor deposition with CH4 gas as carbon source. The carbon nanotubes and the substrate were characterized by a field emission scanning electron microscope for the morphologies,a transmission electron microscope for the microstructures,a Raman spectrograph for the crystallinity,and an Auger electron spectrometer for the depth distribution of elements. The result shows that when the thickness ratio of Ni layer to Ti layer in substrate is about 1,a graphite film with relatively good quality can be formed on the CNT tops.

Intelligent manufacturing： The coupling of technology and industrialization A perspective on intelligent manufacturing can be gained by examining the development stages of modern industrial manufacturing . The use of steam engines as prime movers around 1784 marked an essential step of the First Industrial Revolution （Fig.1 ）, although an early crude form of the steam engine was invented 50 years earlier by Thomas Newcomen.
