Variability and mechanisms of biological pump and organic carbon burial in the western Pacific marginal seas since the last glaciation

海洋生物泵在调节大气—海洋系统中二氧化碳（CO2）的分配中发挥重要作用。但是到目前为止，人类对海洋生物泵的自然演变规律及其调控机制的认知尚存较大争议。本研究对冲绳海槽区输出生产力进行重建，获得过去9万年以来的高分辨率沉积记录。进一步通过数据集成，我们发现整个北太平洋中-高纬度海区输出生产力在末次冰期千年快速气候变化中呈现同步变化规律：即在北半球冷事件（例如Heinrich事件）对应较低的输出生产力，而暖事件对应较高的输出生产力。基于此，我们提出大气铁沉降不是该海区生物泵的主控因子。结合北太平洋与北大西洋气候变化遥相关机制，我们提出北太平洋输出生产力受控于北太平洋中层水演化，作用机制如下：在北半...Mechanisms controlling the export production during the last glaciation in the North Pacific remain controversial. Here, we present a record of 92,000-year export productivity (EP), inferred from sedimentary reactive phosphorus, from the western subtropical North Pacific. On millennial timescale EP decreased during cold stadials when dust supply was high in the northern hemisphere; and vice versa ...学位：博士后院系专业：海洋与地球学院_海洋化学学号：201517000

“砢碜”小考

东北方言中“砢碜“一词的来源不明。语料显示,“砢碜“是“可+碜“的词汇化,“碜“是“惨“的俗字,继承了“惨“的“羞愧“义,后来又引申出“丑、难看“的意思

《红楼梦》中“爬灰”一词来源探析

以往对《红楼梦》中“爬灰“一词由来的解释都不够惬意。本文认为,“爬灰“当是“聚麀“的隐语。“聚麀“又写讹作“聚塵(尘)“,老百姓读白字把“聚麀“读为“聚塵“,而“爬灰“与“聚塵“义通,通过词义引申用为“聚麀“之隐语。从《红楼梦》中“爬灰“和“聚麀“的使用亦可看出曹雪芹用语之精

语言史研究要尊重语言事实——以“(是)…的”句的“语法化”为例

语言事实表明,“(是)…的“句并不源于判断句的语法化。最初“(是)…的“句中“的“的位置还可以出现“了/来“等动态助词,构成“(是)…V+助词“结构,表达现代汉语中“(是)…的“句的句义。从来源上看,“(是)…的“句中的“的“最初与“了“一样是表动作完成的动态助词。语言史的研究要尊重语言事实,不能脱离语言事实进行理论推演

Study on etymology of 30 common words in modern Chinese

近代汉语中的很多常用词，其义虽然明确，其源则不甚明了。本文选取三十组来源不明的常用词，将其放到汉语史的背景中，考察词义的产生、发展以及用字情况，弄清其在汉语中的原始形式（语音形式和文字形式），在有文献可考的历史中是如何演变成今天的形态的，属历史语言学的范畴。 新词语或旧词新义的产生，往往是各种因素综合作用的结果，因此，本文注重多角度、多途径地探讨常用词的来源及发展变化情况。词的语音形式、意义内容乃至书写形式的变化都可能造成一个新词，有些短语因长期连用最终也会凝结成词，这就是词汇化。同一语义场的词会互相影响，在意义上互相渗透，一些语义场的形成是类化构词的结果。另外，方言对通语的影响也不可忽视。...There are many words in modern Chinese that we know what they mean but we don’t know their etymology. In this paper, we choose 30 common words whose etymology is unclear, and discuss the emergence and evolution of these words including the changing process of the written forms in the background of the history of Chinese language. What we learn belongs to historical linguistics, we put these words...学位：文学博士院系专业：人文学院_汉语言文字学学号：1022010015385

Ga掺杂δ-Pu的密度泛函理论计算

&delta;-Pu为Pu的高温相,掺杂少量的Ga即可使其在室温下稳定存在.本文采用密度泛函理论方法,对不同掺杂量体系进行晶体结构和电子结构计算,主要包括体系的晶格常数、密度、形成能、态密度、电荷密度和Mulliken布居分析.结果表明：在研究范围内,Ga掺杂后,体系晶格常数降低,密度增大,6.25%（原子百分比,下同）掺杂量体系的稳定性高于3.125%和12.5%掺杂量的体系;Ga掺杂使得Pu周围体系电子的局域性增强,成键能力增强,揭示了Ga稳定&delta;-Pu的电子机制.Ga和Pu之间为金属键,发生的作用主要由Pu的7s、6p、6d和Ga的4s、4p轨道电子贡献,但这种成键作用相对较弱,使得掺杂体系可以保持原有的力学性能和机械加工性能.Ga对&delta;-Pu的稳定作用主要在于改善Pu原子的成键性能,而不是与Pu原子直接成键.</p

目的 研究高危型人乳头瘤病毒（HR-HPV）感染相关的宫颈病变程度与抗人乳头瘤状病毒（HPV）抗体水平的相关性,探讨HPV致病的免疫学问题。方法 选取2012年1月-2013年6月在该院妇产科门诊就诊的女性中选取60例病理确诊为女性宫颈病变（CINⅠ及以上）,且宫颈脱落细胞的DNA检测为HR-HPV阳性者为研究组,根据组织学检测结果将研究组进一步分为低度病变组30例（CINⅠ）和高度病变组30例（CINⅡ或Ⅲ）。对照组为经核酸检测无HPV感染且病理诊断未见癌前病变的门诊患者60例,按年龄进一步分为低年龄组和高年龄组。低年龄组和高年龄组与低度病变组和高度病变组的年龄差异无统计学意义（P〉0.05）。分别抽取研究组及对照组外周血,检测其抗HR-HPV L1 Ig G抗体及中和抗体滴度,比较研究组与对照组抗体阳性率及抗体滴度水平的差别。结果 研究组血清中的抗HR-HPV L1 Ig G抗体阳性率及抗体滴度均高于对照组（P〈0.05）;低度病变组患者血清中的抗HR-HPV的中和抗体滴度高于相应对照组（P〈0.05）,而高度病变组的抗HR-HPV的中和抗体阳性率及抗体水平与相应对照组比较差异无统计学意义（P〉0.05）。结论 宫颈病变患者血清中抗HR-HPV L1 Ig G抗体升高,说明HPV感染可引起机体的体液免疫反应。低度病变组的中和抗体水平相对较高,可能是机体产生的中和抗体阻止了病毒的进一步感染。高度病变组的Ig G抗体和中和抗体均低下,说明进入CINⅡ/Ⅲ后HPV已经逃避了免疫系统的监视。基金项目：厦门市科技局项目（3502220124050）;2011年福建省科技计划项目资助计划,青年创新项目（20111）00310517
