  • 简介:为杂草的成功理解原因,我们调查了叶建设,和米饭和它的主导的杂草的某些ecophysiological特点的精力充沛的费用。在在所有杂草之中的生理的基础上,CaesuliaaxillarisRoxburgh被发现最严肃,由Echinochloacruss-galliL列在后面。Beauv和EchinochloacolonumL。连接,当时FimbristylismiliaceaeL。Vahl和CyperusiriaL。是稻田的中等杂草。C。axillaris在一个集体基础(1.15g/g)上并且在一个联合起来的区域基础(22.93g/m2)上有最低的叶构造费用(LCC)。比较地更高的特定的叶区域,光合的率,光合的氮使用效率,叶区域比率和叶区域索引提供的C。有进一步的竞争优势的axillaris。低LCC建议杂草比庄稼更高效地利用碳资源并且潜在地在另外的竞争策略viz上花节省的精力。种子生产,生物资源生产和高相对的生长评价,它导致在杂草种子银行的低庄稼产量和增加。

  • 简介:中国microblogs的意见目标抽取在意见采矿起一个重要作用。最近在这个区域有重要进步,特别方法基于有条件的随机的地(CRF)。然而,这个方法仅仅考虑词典相关的特征并且不挖掘暗示了语法、语义的知识。我们建议与一些句法、语义的特征一起合并领域词典的一条新奇途径。途径通过基于词嵌入通过Partof讲话,相关性结构,短语结构,语义角色和语义类似探索语法、语义的信息的一个新奇方法获得领域词典。然后我们把领域词典与意见目标为意见目标抽取与一些特征一起从CRF提取了相结合。COAE2014数据集上的试验性的结果在意见目标抽取的任务与另外的著名方法相比显示出途径的outperformance。
