The Study on Liquidity of China’s Treasury Bond Market

我国及世界各国的发展经验越来越证明，国债市场是经济运行中的一个重要组成部分，有众多不可以替代的功能。但国债市场是否可以很好地发挥功能，首先取决于市场是否具有很好的流动性。证券市场的一切活动本质上都是围绕着流动性进行的：交易商为市场提供流动性；经纪商和交易所为市场组织流动性；无耐心的投资者获得流动性。因此，评价国债市场功能好与坏时，一个关键的指标就是流动性，流动性是市场的生命。如果失去了流动性，市场也就丧失了存在的意义。 我国国债市场经过几十年的发展，已经取得了长足的进步，但是，作为衡量市场生命质量标志的流动性究竟如何，有哪些因素影响流动性，采取哪些措施维护流动性会是最有效的等等，这些问题均需...The experience of developed countries improves that Treasury Bond Market is an important part of the financial system. And whether or not Treasury Bond Market can function smoothly depends on the liquidity of this kind of market. Basically, all activities of security market surround the liquidity: dealers provide the market with liquidity；commission merchants and transaction exchange organize liqu...学位：经济学硕士院系专业：经济学院国际贸易系_世界经济学号：1572006115111

Comparison between Electromyogram and Mechanomyogram during Isometric Muscle Contraction by Frequency Analysis

The muscular activity of rectus femoris (RF) in voluntary isometric knee joint extension was measured by electromyogram (EMG) and mechanomyogram (MMG), and the frequency analysis has done using Fourier transform, and the frequency response of muscular activities was examined. The subjects were normal healthy volunteers (7 men), and the target muscle was RF. The method was to measure maximum voluntary contraction (MVC) in isometric knee joint extension and to measure surface EMG and MMG, keeping the muscle force of 20%, 40%, 50%, 60%, 70% and 80% MVC, respectively, in the fixed time calculated from measured MVC. The measurement was carried out in sitting position. The flexions of knee joint were 90 and 60 degrees. And, the hip joint flexion was 90 degrees, the lower leg rotation 0 degree, and the ankle joint dorsiflexion 0 degree. As a result, it was known that EMG detects electrical activity itself of muscle. However, it was also made clear that MMG is detecting the change of proper oscillation frequency of muscle by the change of muscle compliance. The change of muscle compliance is correlated with rate cording and recruitment. Then, it suggests that the status of muscle contraction is especially sensitively detected by MMG

细胞角蛋白19片段抗原21-1含量化学发光微粒子定量免疫检测方法的建立

目的建立细胞角蛋白19片段抗原21-1(cytokeratin 19 fragment 21-1,CYFRA21-1,简称CY21-1)含量的化学发光微粒子免疫检测方法(chemiluminescent microparticle immunoassay,CMIA)。方法原核表达制备重组CY21-1(r CY21-1),用其免疫BALB/c小鼠后,收集小鼠脾脏细胞,常规杂交瘤技术与Sp2/0进行融合,制备CY21-1单抗。间接ELISA法筛选可稳定分泌CY21-1抗体的杂交瘤细胞,分别标记微性磁珠(magnetic beads,MB)和吖啶酯(acridinium ester,AE),筛选可特异检测CY21-1的单抗配对,建立CY21-1 CMIA,同时验证方法的线性及灵敏度,并与同类试剂盒进行比较。结果经筛选获得了一组能特异检测CY21-1的单抗配对MB*26B5-3E4*AE,建立的CY21-1 CMIA对检测CY21-1校准品的线性范围为0.1~1 000 ng/m L,R~2=0.992 3,检测灵敏度为0.076 ng/m L。该方法与美国雅培公司生产的Abbott CY21-1 CMIA诊断试剂盒平行检测250份临床血清标本的结果具有良好的相关性(R~2=0.961 6)。结论成功建立了CY21-1 CMIA,且具有良好的线性及灵敏度,为我国肺癌的临床筛查和早期诊断奠定了基础。福建省科技重大专项(2015Y0051,2011YZ0002-1);;厦门市科技计划项目(3502Z20120008
