    经济波动是宏观经济学者关注的研究领域。大量研究经济波动的文献集中分析中国经济波动典型特征和波动的来源,或者省份经济波动来源。另一方面,近年来空间计量方法则在研究区域经济收敛的文献中得到广泛的运用,例如分析中国省份经济增长存在的“俱乐部收敛”,经济增长和城市规模存在集聚效应等现象。但是,只有少数文献使用空间计量方法分析省份经济波动,并且尚未发现使用空间计量方法估计省份经济波动空间联系系数的文献。本文将估计省份经济波动的空间联系系数,进一步充实经济波动和地区经济联系的研究。 在估计空间联系系数之前,本文借用KoseMA,YiKM.(2006)的三国模型,分析地理距离会如何影响技术冲击引起的经...Economic fluctuations draw a lot of attentions from macroeconomics scholars, as many literatures analyze the typical characteristics of China’s economic fluctuations and the sources of its national or provincial business cycles. Meanwhile, in recent years spatial econometrics got increasing applications in studies on regional economic convergence, topics such as “club convergence” of China’s provi...学位:经济学硕士院系专业:经济学院_西方经济学学号:1722010115204

    内容提要本研究用实验语音学的方法对比了厦门普通话和北京普通话的语调,发现厦门普通话的语调具有方言特征。文章以语句的音高曲线特征为主要观察对象,分别从语调趋势线、语调调阶和句中字调调型的变化三个方面进行分析。同时也考虑了时长调节特征。研究发现:1.不论陈述句还是疑问句,厦门普通话的整体调阶都比北京普通话的高。2.厦门普通话和北京普通话在区别陈述与疑问语调上有两点相同表现:⑴疑问句的语调调阶水平比陈述句的高,边界调的音高差异尤其显著。⑵疑问句的句末韵律词发生了规律性的时长调节,边界调的时长延长。从这两点可以看出边界调在表达疑问中具有特殊作用。3.二者在陈述与疑问语调的区别上还存在两个差异:⑴语调的...Abstract This study makes use of experimental phonetics to compare the intonation between the Putonghua spoken in Beijing and Xiamen. It is found that the intonation in Xiamen Mandarin contains characteristics of dialect influence.

    作为一款具有较强价值创造能力的信贷产品,个人住房贷款以其资本占用少、风险权重低、经济资本收益率高等特点,广受各商业银行青睐,业务份额在各项贷款中占比不断攀升,并已成为商业银行新的利润增长点与长期战略方向。近年来,在城镇化持续推进、经济增速趋缓等因素叠加作用下,个人住房贷款的显性和隐性风险开始逐渐暴露,这必然会使房地产及其上下游产业、居民住房消费乃至整个国民经济产生连锁反应。商业银行如何识别、转移、控制、管理个人住房贷款风险,从而构建起由个人、社会、银行、政府共同组成的风险防范体系,已是当前我们亟待推进的一项热点问题。 从研究意义来看,本文通过甄别、分析房地产市场中各方主体的主要风险点,有针对...As a credit product with a strong value-creating ability, individual housing loan gains popularity in commercial banks because of its small capital coefficient, low risk weight and high rate of capital return. With its business share increasingly rising in various loans, it has become a new profit growth point and long-term strategy direction of commercial banks. In recent years, under the additiv...学位:工商管理硕士院系专业:管理学院_工商管理硕士(MBA)学号:1792011115078

    目的探讨IL-20及其受体在大鼠实验性自身免疫性心肌炎(EAM)急慢性期各阶段的表达。方法将提纯精制后的猪心室肌球蛋白加等体积含结核杆菌H37Ra株的完全弗氏佐剂充分混合,于Lewis大鼠双后足皮下注射制作大鼠EAM模型;将15只大鼠按随机数字表法分成3组,每组5只,分别于3、6、12周后处死取心肌组织进行检测。另取5只大鼠注射0.9%氯化钠注射液作为对照组。HE染色评估EAM急慢性期各时点心肌损伤程度;应用实时荧光定量RT-PCR检测IL-20及其受体链(IL-20R1/R2,IL-22R1)在各时点的mRNA表达;应用Western blotting法检测IL-20在各时点的蛋白表达。并以ELISA检测不同时点心肌组织匀浆IL-20蛋白含量[IL-20蛋白/总蛋白(pg/ng)]。结果 IL-20在EAM急性期3周时表达逐渐升高,6周时达峰值,12周时又逐渐减少。IL-20的组织蛋白水平与基因表达相一致。结论 IL-20可能参与大鼠EAM的疾病过程,并且可能在EAM的晚期炎症及慢性心肌纤维化的机制中起重要作用

    研究了聚氨酯泡沫应用于固定化盘基网柄菌的可行性,发现以简单处理过的聚氨酯泡沫为载体,能够高效实现盘基网柄菌的固定化培养。考察了载体粒径大小、载体量和摇床转速等对固定化培养的影响,在优化的培养条件和固定化条件下,盘基网柄菌的最大细胞密度是悬浮培养的2~4倍。The immobilization of D.discoideum with polyurethane foam(PUF) was proposed and the effects of PUF's properties on the immobilization was examined.The results showed that PUF was a suitable carrier for the efficient imoblization of D.discoideum.The effects of PUF addition and culture conditions were optimized to attain high density of D.discoideum.Under optimized culture conditions,high cell density of D.discoideum(4.56×107 cells/mL) has been achieved in the shake flasks,which was 2~4 times higher than that of free-cell culture in the axenic medium.国家自然科学基金资助项目(30370039

    采用密度泛函理论(dfT),在b3lyP/6-311+g**水平上,研究了三类包含平面四配位碳原子(PTC)和平面五配位碳原子(PPC)的硼碳化合物.这三类新型化合物是由C3b2H4(包含PTC)、Cb4H2(包含PTC)和Cb5H2(包含PPC)三种稳定结构和—CHCH—单元连接起来而得到的.在理论上探讨了这些新型的硼碳化合物的成键特征,光谱性质以及芳香性.研究结果表明:包含PTC和PPC原子的能量最低的结构,在不受对称面限制的条件下,具有C2V对称性的顺式立体构型比具有反式平面构型的化合物稳定.计算的核独立化学位移(nICS)显示,这些新型化合物的三元环中心有强的芳香性.计算最稳定硼碳化合物的PTC和PPC原子的WIbErg键指数(WbIS)表明PTC和PPC的成键遵循八隅规则.Unusual boron-carbon compounds containing planar tetracoordinate carbon (ptC) and planar pentacoordinate carbon (ppC) were investigated using density functional theory (DFT) at B3LYP/6-311+G** level.These novel compounds are generally assembled with three types of stable structural units C3B2H4 with ptC, CB4H2 with ptC, and CB5H2 with ppC as well as linking elements—CHCH—.On the basis of calculation results the bonding features, spectroscopic properties, and the aromaticities of these novel boron-carbon compounds were discussed.Results show that as for the lowest-energy compounds contained ptC and ppC without being limited by symmetrical planes, stereo cis-structures of C2v symmetry are more stable than the corresponding planar trans-structures.Calculated nucleus-independent chemical shift (NICS) values show that the aromaticity of the center of the three-membered rings is the strongest.The total Wiberg bond indices (WBIs) of the ptC and ppC atoms of the most stable structures of the boron-carbon compounds indicate that the ptC and ppC obey the octal rule.supportedbytheExcellentSciencePre-researchProjectofShaanxiNormalUniversity(China)in2008---
