乙醇对斜生栅藻叶绿素荧光特性以及油脂积累的影响研究

为了研究乙醇对斜生栅藻（Scenedesmus obliquus XJ002）藻株光合效率以及胞内油脂积累的影响,首先采用酶标仪作为检测仪器,研究了尼罗红终浓度、二甲基亚砜（DMSO）体积分数、尼罗红染色时间对藻株油脂测定的影响,分析了藻株胞内油脂含量与尼罗红染色相对荧光信号强度之间的线性关系,为XJ002藻株胞内油脂含量的测定提供了一个简便、快速的方法.其次研究了不同体积分数的乙醇添加对XJ002藻株生物量、叶绿素荧光特性以及胞内总脂含量的影响.结果表明:XJ002藻细胞尼罗红染色最佳条件是:二甲基亚砜体积分数为2%,尼罗红的终质量浓度为2.0μg·m L-1,尼罗红的染色时间为5 min.添加高浓度乙醇导致藻细胞生物量与光合色素含量显著下降,影响了藻细胞光系统Ⅱ反应中心能量分配,抑制光系统Ⅱ反应中心受体侧电子传递活性.当乙醇处理浓度为3%时,XJ002藻株胞内总脂含量较对照组提高了5.19%,该研究表明乙醇可以作为XJ002藻株油脂积累的潜在诱导试剂.国家自然科学基金项目(41666007);;内蒙古自治区自然科学基金项目(2015MS0335);;包头市应用研发资金科技计划项目(2015Z2010-3

Research On the Question of Commercial Banks Social Responsibility——From a Focus on System-Level Analysis

晚近商业银行社会责任运动的兴起，既是经济全球化与自由化发展的一个副作用，也是和谐社会建设的必然。这种责任超越了以往商业银行只对股东负责的范畴，强调对股东、员工、消费者等在内的利益相关者的社会责任，并应对社区、环境保护、社会公益事业等提供支持。然而，与国外同行比较，国内银行在履行社会责任方面显然存在不足，尤其在制度上得不到相应的法律保障。因此，本文从商业银行社会责任的理论基础入手，在对比国内、外商业银行社会责任履行情况的基础上，对我国商业银行社会责任的制度构建提出了相应的探讨，以促进商业银行真正将履行社会责任转变为自觉行动。 全文包括前言、正文与结束语三部分。正文共分四章。 第一章为“商业银...The lately on rise of social responsibility of commercial banks movement is not only a by-product of the economic globalization and liberalization, but also the inevitable consequence of a harmonious society construction. This responsibility goes beyond the orthodox value of commercial banks that the shareholders shall be the only to answer to, reaching the emphasis on the social responsibility to...学位：法学硕士院系专业：法学院法律系_经济法学学号：1292006115049

代谢中间物对斜生栅藻叶绿素荧光特性以及油脂积累的研究

为了研究代谢中间物(柠檬酸与苹果酸)的添加对斜生栅藻(Scenedesmus obliquus XJ002)光合效率以及胞内油脂积累的影响,研究了代谢中间物的添加对XJ002藻株生物量、光合色素、叶绿素荧光特性以及胞内总脂含量的影响。结果表明:添加高浓度代谢中间物导致藻细胞生物量与光合色素含量显著下降,损坏藻细胞光系统II反应中心供体侧的放氧复合体(OEC)结构,抑制光系统II反应中心受体侧电子传递活性。当柠檬酸与苹果酸处理浓度为0.15 g/L时,XJ002藻株胞内总脂含量是对照组的1.85倍和1.34倍。高浓度代谢中间物的添加,显著提高了XJ002藻株胞内总脂含量,与苹果酸相比,柠檬酸的添加效果更佳。国家自然科学基金(41666007);;内蒙古自治区科技计划项目(201601061);;内蒙古科技大学大学生创新基

Japanology 2005 Open Workshop : What can China learn from Japan’s culture of technology?

This is a transcript of an open workshop jointly sponsored by the Japanology Research Group and the Center for International Japan-Studies of Hosei University. It took the form of a dialogue between the Chinese specialist in comparative culture, GAO Zengjie, and ADACHIHARA Tōru, who has worked for many years to promote technological advance in China. The dialogue was mediated by KIYONARI Tadao, economist and President of Hosei University.In his comparison of the technological cultures of China and Japan, Gao suggested that the biggest turning point in the development of the two countries occurred at the time of Japan’s medieval age. In contrast to China, where society was led by a class of Confucian literati concerned above all with proper governance of their country under the emperor, the ‘son of heaven,’ Japan’s medieval age was dominated by the emergence of a military ruling class. Leaders in China, therefore, were occupied with issues that tended toward the philosophical, while leaders in Japan had to deal with more practical matters, primarily those of warfare, that led to a greater interest in technological development and the application of new technologies.Kiyonari then pointed out that Japan’s medieval age also brought with reforms in the fields of agriculture and economics, which were adopted and systematized in the feudal system of the Edo period. Only at this time did Japan adopt Confucian ideas of governance, but at a level that had little to do with the daily life of the people, thus producing a two-tiered social structure, with agricultural workers, craftsmen and merchants inheriting the earlier concern for technology. This paved the way for Japan’s quick industrialization after the Meiji Restoration, and helped it establish its reputation as an industrial power.In response to Adachihara’s query as to what China can learn from Japan’s culture of technology, Gao stated that Japan’s technological advances have been fostered by the Japanese concern for technical detail, the skills of Japan’s workforce, and the ‘spirit’that can be discerned in their concern for technical advance. While China is becoming successful at producing certain types of relatively simple products, its people still have much to learn with regard to their basic attitude toward technology and the mastering of technological advances

富勒烯和碳纳米管稳定性与形成机理的图形理论定性研究

应用图形理论对不同种类碳簇体系的Kekulé结构数进行了计算,并在半经验方法(AMI)和密度泛函理论(DFT)水平上,讨论了不同种类碳簇的结构与稳定性。基于Kekulē结构计数,C-Cσ键数,富勒烯的表面曲率和能量,对石墨碎片的卷曲行为以及富勒烯的形成机理进行了讨论。研究结果表明石墨碎片的卷曲,一端闭合,到完全封闭,可以减少结构中的悬键;随着新的C-Cσ键生成,Kekulé结构数将急剧地增加,特别是大的富勒烯和碳纳米管,这种增加更为显著。大量Kekulé结构间的共振使体系获得显著的共振稳定化能,稳定具有张力的富勒烯和碳纳米管,并驱动平面碳簇结构向闭合结构的转化。对于Kekulé结构数相近的碳笼,表面曲率对曲面结构的稳定性有重要的影响。把Kekulé结构计数和表面曲率结合起来,可以合理地理解球形笼状富勒烯、闭合纳米管和类“洋葱”型结构等高碳簇在热力学上的稳定性

Effect of Fluoroethylene Carbonate Additive on the Performance of Lithium Ion Battery

在1MOl·l-1lIPf6/碳酸乙烯酯(EC)+碳酸二甲酯(dMC)+碳酸甲乙酯(EMC)(EC、dMC、EMC体积比为1∶1∶1)电解液中加入体积比为2%的添加剂氟代碳酸乙烯酯(fEC),用循环伏安法(CV)、扫描电镜(SEM)、能量散射光谱(EdS)、电化学阻抗谱(EIS)等方法,研究了fEC对锂离子电池性能及石墨化中间相碳微球(MCMb)电极/电解液界面性质的影响.结果表明,体积比2%fEC的添加可以抑制部分电解液溶剂的分解,在MCMb电极表面形成一层性能优良的固体电解液相界面(SEI)膜,降低了电池的阻抗,明显提高了电池的比容量和循环稳定性.Fluoroethylene carbonate (FEC) with a volume ratio of 2% was added to the electrolyte containing 1 mol· L-1 LiPF6 in ethylene carbonate (EC), dimethyl carbonate (DMC), and methyl ethyl carbonate (EMC) (1∶1∶1 by volume).The effects of FEC on lithium ion battery performance and on the mesocarbon microbead (MCMB) electrode/electrolyte interphase were studied by cyclic voltammetry (CV), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and electrochemical impedance spectroscopy (EIS).The results indicated that the application of a 2% (volume ratio) of FEC suppressed electrolyte decomposition and caused the formation of an excellent solid electrolyte interphase (SEI) film on the MCMB electrode.The battery resistance decreased while the specific capacity and cyclic stability of the battery increased.国家基础研究重大项目计划(2007CB209702)资
