Dip-coating is a conventional solution processing technology to prepare large-area films at a low cost and with cheap facilities. For semiconductor film processing, crystal orientation and thickness uniformity are the primary factors that determine the film quality and its electrical performance. These requirements are readily satisfied with the dip-coating method because the film morphology can be effectively optimized by tuning the withdrawal speed. This work optimizes the withdrawal speed for the dip-coating of patterned semiconductor films of 400×500 mm2 as well as that for film dip-coating on the whole surfaces of the substrate. For both experiment, optimized electrical mobility is achieved at the same withdrawal speed, however, the random crystal orientation of the patterned films causes a remarkable decrease in device performance.

The traditional remanufacturing mostly focus on the technical measures which are aimed to keep and restore the available state after products design, produce and put into use. The design work before they are put into use is less involved. The high-level product innovation design theory, for exampleTRIZ, can scientific refining innovative ideas and provide mature theoretical system and method for design problems. Reasonable use them to innovative design the remanufactured products can scientific guiding products remanufacturing process, increase the scientific nature of the decision-making program and create enormous social and economic benefits.

Parsing Chinese is a key issue in NLP. Many controversies arise from Chinese special sentence patterns. This paper puts forward a novel model Feature Structure theory to resolve the semantic labeling of Chinese special sentence patterns. We analyze the difficulties in annotating these sentences, and compare Feature Structure with dependency structure. Feature Structure represents more semantic information and more semantic relations. Feature Graph is a recursive undirected graph, allows nesting and multiple correlations.

Based on the pilot experiment on quick start-up of filter for removing manganese, amplification experiment was carried out. High concentration aeration and low concentration running were used in this experiment as starting mode. The maturity period of the filter for manganese removal is 9 days. Through the research on the distribution of manganese ions in filter bed by different filtration rate, the result shows a bigger depth of the filter bed is needed with the increase of filtration rate. For raw water with manganese ions concentration of 1.0-1.5 mg•L-1, the highest flow rate that can be handled by this equipment is 0.7 m•h-1. The blockages in filter bed can be washed out under the condition that the back washing intensity is 7.81 L•s-1•m-2 and the back washing time is 5 min. The back washing period of the filter is 13 days.

Jetting power has been applied more and more frequently to create trench in the seabed to bury cables or pipelines under a protective layer of sand in offshore engineering. However, there are still several key problems to be understood further and solved both in their design and operating. This study investigates the topographic deformation due to the scour of silt beds which lie below marine pipelines and are impinged by moving two jets in a model experimental system. The response of silty sea beds was also examined during the experiment. The important parameter that influences the trenching performance, the jet velocity, was studied. The speed of the jet horizontal motion was varied to examine its effect on the scour profile. By presenting the variation of a scour profile with time after impingement, the change process was analyzed. The asymptotic scour profiles were found to be very similar when made non-dimensional, and a function was employed to describe the non-dimensional profile. The results of the above work will permit a better understanding of the mechanisms controlling the performances of underwater trenching by jet trenching machines.

A group of new composite antibacterial agent was prepared by ion adsorption method, in which silver ion is the main active ingredient, with alumina and zirconia as the carriers. The influence of mixing time, content of zirconia, silver ion content and calcination temperature on the antibacterial properties of the composite powder are discussed in this paper. The results show that when the content of ZrO2 is 4%, Ag+ content is 4%，mixing temperature is 70°C，mixing time is 4h, the composite antibacterial agent has a good property. ZrO2 can be loaded in the large hole of Al2O3 as a second carrier; it can keep a larger surface area-based carrier, suitable pore structure, and also play an important role on antibacterial properties at high temperature.

The influence of Nano- CaCO3 on the mechanical property of PALC was studied in the paper. And the mechanism of Nano- CaCO3 modified cement-based materials was also discussed by means of X-ray diffraction and SEM. The results shows that the PALC with 2% of added Nano-CaCO3 by weight of cement has an optimum splitting strength, in which the increase of splitting strength are about 15.2%,20.4% and 19.7% at 3days,7days and 28 days. The reasons for causing the above results are because Nano-CaCO3’s filling effect of micro-particle, surface effect of nano-particles as well as micro-nucleus effect.
