In the summer of 2003 and 2004, characterized by a rapid glacier retreat, a stony surface covered by well-structured organic-rich mineral debris was observed very close to the Indren glacier terminus(Monte Rosa Massif, NW Italy, 3100 m ASL), on an area covered by the glacier tongue till the year before. The origin and type of this organicrich material were investigated, in order to detect their characteristics, potential sources and fate within the foreland system. The deposits were dated using carbon-14 and analyzed for the chemical characteristics of the organic component, the elemental composition of the mineral fraction and presence of microbial markers. The material, granular and dark in color, had a total organic carbon(TOc) content ranging between 17.4 ± 0.39 and 28.1 ± 0.63 g kg^(-1) dry weight(dw), significantly higher than the surrounding glacial till(~ 1.4 g kg^(-1) dw), although only 0.33% of it was in water soluble form. Microbial carbon(c) and nitrogen(N) accounted for 10.6% and 3.13% of TOc and total N, respectively. Dissolved nitrogen(N), mainly present as ammonium, represented 2.40% of the total N. The low aromatic component and large presence of nitrogen(N)-derived compounds suggested that most of the organic carbon(Oc) in these organic-rich mineral deposits was derived from microbial cells, although the high average radiocarbon age of about 2900 years may also point to the contribution of aeolian depositions of anthropogenic or natural origin. Elemental composition and the crustal enrichment factor of trace elements in the mineral fraction of the aggregates corroborated the hypothesis that most part of the accumulated material derived from ice meltwater. Some indicators of the colonization of these deposits by microbial communities were also reported, from the abundance of DNA and phylogenetic markers, to the presence of bacterial taxa commonly able to thrive in similar habitats. All these elements suggested that such kind of deposits may have a p

在多对象、多属性的评论文本中,评价对象和评价属性的缺省识别对于观点挖掘有着重要的作用。针对情感观点句中评价对象和评价属性的缺省问题,该文提出一种有效的缺省项识别方法。首先构造缺省项识别规则集,用于获取待识别的缺省项侯选集;将缺省项识别问题看作一个二元分类问题,选用词法和依存句法作为特征,使用决策树分类算法c4.5训练分类器模型,在测试集上对待识别的缺省项进行判别。实验结果表明,使用依存句法特征集分类的F值优于词法特征集约2%。将词法和依存句法两类特征融合与单类特征相比,分类精确率和F值分别提高了10%和5%左右,说明词法特征和依存句法特征的融合有利于缺省项识别。

建立了一个数值模型,来计算并论述在固体氧化物燃料电池(SOFc)阴极中的扩散和渗透共同作用下的传质现象。经过对比分析,研究了阴极内压力梯度对气体传输、气体分布,以及浓度过电压的影响。研究表明,文献中所采用的扩散模型可近似模拟SOFc阴极的浓度过电压。但是,对于气体成份沿阴极的分布,则必须考虑压力梯度的影响。在此提出的模型可进一步深化,以优化SOFc电极的多孔结构。
