An Experimental Study on the Drag Property of High Temperature Particles Falling into Cold Liquid Pool

This experiment is to study the special resistant induced by the high-speed evaporation surrounding the moving high-temperature particles. An observable equipment was designed, in which the first 11 experiments were performed by pouring one or several Zirconia spheres with various high-temperature and a diameter of 3-10mm into a water pool. The particles falling-down speeds were recorded by high-speed photographic instrumentation,and pressures and water temperatures were measured. A comparison between the experiments with cold and hot spheres respectively, employing three different sphere types each, was presented. The experimental data, com-pared with the theory of the evaporation drag model, are nearly identical.     

A Semi-automatic Method Based on Statistic for Mandarin Semantic Structures Extraction in Specific Domains

This paper proposed a new method of semi-automatic extraction for semantic structures from unlabelled corpora in specific domains. The approach is statistical in nature. The extracted structures can be used for shallow parsing and semantic labeling. By iteratively extracting new words and clustering words, we get an inital semantic lexicon that groups words of the same semantic meaning together as a class. After that, a bootstrapping algorithm is adopted to extract semantic structures. Then the semantic structures are used to extract new key words and augment the semantic lexicon. The resultant semantic structures are interpreted by persons and are amenable to handediting for refinement. In this experiment, the semi-automatically extracted structures SSA provide recall rate of 84.5%.     

虾峙门航道船舶通航能力评估研究

随着宁波-舟山港吞吐量的迅速增长,虾峙门航道通航能力将面临越来越大的压力。通过对宁波-舟山港吞吐量的预测,交通流量的分析,航道双向通航理论的研究,对虾峙门航道通航能力进行评估。认为虾峙门航道能满足双向航路的要求,2010年前应开通虾峙门双向航路或开通条帚门航道,以保持宁波-舟山港航道与港口的协调、可持续发展。
