A Study on Energy Demand and Carbon Discharges Peak Value of Zhejiang in Future

2009年12月召开的哥本哈根气候峰会在全民中做了一次能源、碳足迹、气候变化的知识普及，同时也将碳排放量巨大的中国推到了风头浪尖。作为附件Ⅱ所列国家，中国目前并不具有减排义务，但是本着对人类未来负责、努力实现可持续发展的态度，中国提出自愿减排目标：2020年单位GDP二氧化碳排放比2005年降低40%-45%；非化石能源占一次性能源消费15%；2020年森林面积比2005年增4000万公顷。中国的减排目标定将作为约束性指标纳入国民经济和社会发展的中长期规划，目标的实现必然要将指标细化到各个省份。 浙江是一个典型的经济大省和能源小省并立的省份，经济发展水平在全国处于发达水平，但能源资源极为匮乏...The United Nations Climate Change Conference (COP15) popularized environmental protection knowledge on energy, carbon footprint, climate change on December 2009. At the same time, China-as the world's largest carbon emissions country-became the focus. COP15 was held in Copenhagen-the capital of Danish. As an attachment Ⅱ country, China doesn’t have emission reduction obligations at present. Howeve...学位：经济学硕士院系专业：经济学院金融系_能源经济学学号：1562007115156

The Marine Culture of Zheng Group from the Perspective of the Sunken Ships in the Littoral of Fujian and Guangdong Provinces during Late Ming and Early Qing Dynasty

闽粤沿海自古以来就是海上交通、海外贸易和军事兵防的重要地带，东山、广澳位于闽粤沿海交界的海域，重要的地理位置使其成为历代兵家必争之地，也是海上交通和贸易的必经要道之一。90年代以来，水下考古工作人员及当地文物部门在东山、广澳进行了一系列的考古调查工作，采集发掘了一批明末清初的沉船文物。本人在前人研究的基础上，从这两次沉船文物的内涵入手，结合闽粤沿海其他相关沉船出水资料和古窑址等考古资料，分析东山、广澳沉船的性质、年代及其它文化内涵，结合历史文献考察明末清初郑氏集团在闽粤的活动，并且尝试透物见人探讨沉船背后明郑时期的海洋军事、贸易和航路港市等海洋文化。全文包括绪论、正文和结语。 第一章，绪论，...The littoral of Fujian and Guangdong provinces has been an important area of maritime traffic, overseas trade and military defense since ancient times.

宋元瓷枕造型装饰分类及其民俗文化艺术浅析

[中文摘要] 宋元是瓷枕发展的兴盛时期。它在作为日用品广泛流行之外，更是一种艺术品，是集造型、绘画、书法、文学为一体的工艺品。人们在各式各样的瓷枕上绘画书写，把心理意识、美好希望等寄托在丰富多彩的造型和装饰纹样上。因此通过对瓷枕的分类研究，我们可以了解到宋元时期的社会民俗和文化艺术。 Abstract: The period from Song to Yuan is the silver age of the development of porcelain pillow. As a popular commodity, the porcelain pillow is still a sort of art, a sort of craftwork with shape、painting、calligraphy and literature. People paint and calligraphy on porcelain pillow of all sorts, expressing their consciousness and wishes in the rich and colorful shapes and decoration. So from studying porcelain pillow of sorts, we can understand the folk-custom and artistic culture in that society of Song-Yuan dynasties

视网膜显微手术机器人的约束运动规划及仿真

为了辅助医生完成视网膜显微手术中精细的手术操作,过滤颤抖、提高精度和稳定性,提出一种生成手术机器人空间运动约束的方法——虚拟固定器(VF).首先,通过引入手术环境约束和任务约束,采用加权、线性化的多目标约束条件,根据用户的输入设置目标函数,构造了视网膜显微手术中所需的6个虚拟固定器基元.在此基础上,以远程运动中心虚拟约束(RCM VF)的生成为例,通过约束运动基元的组合,推导了复杂约束运动的实现方法.各约束运动基元算法及复杂约束运动算法的仿真结果表明,手术器械可以按照虚拟固定器的定义实现特定的约束运动.最后,在各手术步骤中引入约束运动基元的基础上,在乒乓球和离体猪眼球上进行了手术操作实验,证明了在该虚拟固定器的引导下,视网膜机器人可以完成高难度的手术操作,验证了所提出算法的合理性和有效性.国家自然科学基金(51175013);;福建省高校青年自然基金青年重点项目(JZ160493

Functional groups of benthic macrofauna in the 14th Yong intertidal zone of Nansha,Guangzhou

大型底栖动物根据食性可分为浮游生物食者(planktophagous,Pl)、植食者(phytophagous,Ph)、肉食者(carnivorous,C)、杂食者(omnivorous,O)和碎屑食者(detritivorous,D)五个功能群。本文根据2007–2008年度和2013–2014年度在茳芏(Cyperus malaccensis)、海桑(Sonneratia caseolaris)2种生境调查获得的各4个季度的大型底栖动物数据,分析了广州南沙十四涌潮间带大型底栖动物功能群的生境差异、季节变化和年际变化。2007–2008年度采集到26种大型底栖动物,低于2013–2014年度的36种。无论是2007–2008年度还是2013–2014年度,茳芏、海桑生境的大型底栖动物均以植食者的栖息密度和生物量最高,碎屑食者的栖息密度和生物量最低。生境比较得出,茳芏生境大型底栖动物浮游生物食者(Pl)的丰富度指数(d)、均匀度指数(J)和多样性指数(H')均高于海桑生境。年度比较得出,在茳芏和海桑生境,2013–2014年度浮游生物食者的丰富度指数、均匀度指数和多样性指数均高于2007–2008年度,这是因为2013–2014年度采集到红树蚬(Gelonia coaxans)和彩虹明樱蛤(Morerlla iridescens)等,而2007–2008年度没有采集到。Benthic macrofauna were classified into 5 functional groups,i.e.planktophagous(Pl),phytophagous(Ph),carnivorous(C),omnivorous(O) and detritivorous(D).The biotope difference,seasonal and annual variations of functional group of benthic macrofauna in the intertidal zone of the 14 th Yong of Nansha,Guangzhou were analyzed in this study according to the four seasonal data of benthic macrofauna collected in two biotopes(Cyperus malaccensis and Sonneratia caseolaris) in 2007–2008 and 2013–2014.A total of 26 species were recorded in 2007–2008,which was lower than 36 species in 2013–2014.Both in 2007–2008 and 2013–2014,phytophagous group showed the highest value while detritivorous group shared the lowest one in density and biomass.Habitat comparison showed that the abundance index(d),evenness index(J) and diversity index(H') of planktophagous group in Cyperus malaccensis habitat were all higher than those in Sonneratia caseolaris habitat.Annual comparison showed that the abundance index,evenness index and diversity index of planktophagous group in 2013–2014 were all higher than those in 2007 –2008 both in Cyperus malaccensis and Sonneratia caseolaris habitats because the planktophagous such as Gelonia coaxans and Morerlla iridescens and so on were collected in 2013–2014 but they were not found in 2007–2008.国家自然科学基金(41176089和41376113

含氯消毒剂杀灭船舶压舱水中3种优势赤潮藻种的实验研究

〔目的〕研究含氯消毒剂在实验室水平对船舶压舱水中赤潮藻的杀灭效果,为现场实验提供理论依据。〔方法〕通过测定叶绿素a的含量,比较药物作用前后的藻细胞数量,反映药物对试验藻种的量效和时效关系。〔结果〕药物浓度、作用时间与杀灭效果呈现正相关趋势,但较高的作用浓度决定了高昂的投药成本和潜在的环境代价。〔结论〕含氯消毒剂不宜单独用于杀灭压舱水中的赤潮藻类,可以考虑作为压舱水综合处理体系中的高层次处理方法

福建外来船舶压舱水中浮游植物种类组成与丰度及其影响因素的初步研究

2006~2008年间对进入福建沿海4个主要港口的12艘国际航船所携带的压舱水进行浮游植物种类组成和丰度分布的调查.此调查共检测出浮游植物7个门86属239种(含变种和变型),77μm孔径网滤样和20μm孔径网滤样的平均藻类丰度分别为1.2×102cells/dm3(变动在0~9.1×102cells/dm3间)和3.4×103cells/dm3(变动在0~3.0×104cells/dm3间).同时对其中6艘船舶的压舱水样品用f/2培养基培养,共有13种硅藻和1种甲藻被成功培养.文中还分析了压舱水中浮游植物丰度与盐度、水龄的关系,并结合历史资料讨论了压舱水里各类浮游植物的分布

中国东南沿海港口外轮压舱水生物的调查

随机选取东南沿海港口的17艘外来船舶(含8条集装箱船和9条散货船)作为监测对象,进行压舱水浮游植物及动物的物种鉴定和丰度测定,并对监测数据进行统计学分析。检出分属于7个浮游植物门类和5个动物门类的309种外来压舱水生物(包括60种赤潮生物)。外轮压舱水生物的分布及生存状态与水样的水龄和盐度相关。船舶压舱水排放是大家熟知的外来水生生物入侵的主要媒介。本调查结果表明,中国东南沿海外来散货船的压舱水排放所具的潜在生物入侵风险比集装箱船更应受关注

Univ Wollongong, Inst Superconducting & Elect Mat, Wollongong, NSW 2522, Australia 电子邮件地址: [email protected]; [email protected] paper reports the facile synthesis of a unique interleaved expanded graphite-embedded sulphur nanocomposite (S-EG) by melt-diffusion strategy. The SEM images of the S-EG materials indicate the nanocomposites consist of nanosheets with a layer-by-layer structure. Electrochemical tests reveal that the nanocomposite with a sulphur content of 60% (0.6S-EG) can deliver the highest discharge capacity of 1210.4 mAh g(-1) at a charge-discharge rate of 280 mA g(-1) in the first cycle, the discharge capacity of the 0.6S-EG remains as high as 957.9 mAh g(-1) after 50 cycles of charge-discharge. Furthermore, at a much higher charge-discharge rate of 28 A g(-1), the 0.6S-EG cathode can still deliver a high reversible capacity of 337.5 mAh g(-1). The high sulphur utilization, excellent rate capability and reduced over-discharge phenomenon of the 0.6S-EG material are exclusively attributed to the particular microstructure and composition of the cathode.NSFC 2093110426 21003102 21021002 20833005 973 program 209CB22010
