基于词汇吸引与排斥模型的共现词提取

:共现词提取在信息挖掘和自然语言处理中有着十分重要的地位。而传统的共现词提取方法仅仅局 限在单一的一种统计量上,其结果十分不精确,需要人工再进行整理。本文提出了一种基于词汇吸引与排斥 模型的共现词提取算法,并通过将多种常用统计量进行组合,改进了算法的效果。在开放测试环境下,所提取 的共现词其用户感兴趣度为60187 %。将该算法应用于基于Web 的共现词检索系统,在速度和共现词的提取 精度上均取得了比较好的效果。福建省自然科学基金资助项目(A0310009) ;福建省重点科技资助项目(2001J005

PM_(2.5) in Northern Coastal Area of Shandong Peninsula: Correlation between Its Acidity and Chemical Composition in Winter

To investigate the acidity variation characteristics of fine particulate matter (PM_(2.5)) in the areas down-wind of Jing-Jin-Ji region in winter, the Qimu Island Environmental Monitoring Station, situated in Shandong peninsula, conducted a PM_(2.5) sampling project for the period from 3 January-11 February, 2014 according to the sample collection schedule: one sampling every 12 hours. The analytic results of the samples showed that the average mass concentrations of PM_(2.5) during the sampling period were (77.1&plusmn;58.7) &mu;g/m~3; the total content of water soluble ions including SO_4~(2-), NO_3~-, Cl~-, NH_4~+, Ca~(2+), K~+, Na~+ and Mg~(2+) accounted for (37.3&plusmn;16.3)% of PM_(2.5) mass, among others, the share of SO_4~(2-), NO_3~-and NH_4~+ were the most, and no obvious variation of the contents of PM_(2.5) and the ions was noted day and night, but the variation was comparatively remark- able according to the trajectory classification of clustered air mass. On the basis of the assessment by the ion balance method and modeling of ISORROPIAⅡ, total acidity and in-situ acidity were (309&plusmn;544) nmol/m~3and (193&plusmn;292) nmol/m~3, respective- ly, and no notable variation of total acidity of PM_(2.5) was observed for the day and night but the change was significant according to classified clustered air mass. The M-K test indicated that acidity decreased when the 2nd class clustered air mass oc- curred, and the linear regression analysis suggested that it was the in-situ acidity that notably influenced the total acidity and the water content in PM_(2.5) was unlikely the main factor that restricted acidity of PM_(2.5).</p

C-2v-Symmetric C-60 Isomer in the Gas Phase: Experimental Evidence against Buckminsterfullerene (I-h-C-60)

Pure non-IPR (isolated-pentagon-rule) C-60 isomer has rarely been investigated experimentally. The recently reported availability of (C60Cl8)-C-#1809 opens an avenue for experimental investigation of C-#18098(60), a C-2v-symmetric C-60 isomer having two pairs of fused pentagons. Herein, the experiments on C-#1809(60) were performed oil the basis of thermal dechlorination of (C60Cl8)-C-#1809 in the solid state and gas phase. (C60Cl6)-C-#1812 was employed for comparative study. As determined by Raman and other methods, C-#1809(60) from thermal decomposition of (C60Cl8)-C-#1809 crystals readily coalesces to form carbon solid with a collapsed crystal lattice. In contrast, dechlorination via thermal spray of (C60Cl8)-C-#1809 in the gas phase is feasible for investigation of monodispersed all-carbon C-60 isomer, because the existence of C-#1809(60) in the gas phase has been confirmed by experimental evidence from mass spectrometry and high-perfomance-liquid-chromatography.National Natural Science Foundation of China 20525103,20531050,20721001 973 Program,2007CB81530
