Design and Implementation of City Disaster Recovery System of MingSheng Bank Based on GDPC Technology

随着信息系统技术的深入发展和数据大集中模式的广泛推广，银行各类信息系统已逐步从传统的独立的信息系统过渡到了大集中信息系统。相比传统的独立模式，数据大集中系统在带来便利的同时，也扩大了各种数据风险，如果考虑不周，一旦系统出现故障可能带来巨大的损失，这些损失有时无法承受。 2001年6月，民生银行的核心银行业务数据大集中系统上线，为民生银行的业务全面发展奠定了坚实的基础。业务数据开始大集中之后，民生银行获得了更大的效益，但同时也使风险更加的集中和扩大。因此在当前银行数据大集中大行其道的形势下，数据的安全性和灾难恢复显得日益重要。 本论文主要研究和实施高可用性同城灾备银行系统架构，同时也将对该架...With the development of information technology and mode of data centralization, all kinds of banking information system has been gradually from the traditional independent information system transition to a centralized information system.

Sparse Reconstruction Algorithm of NMR Spectroscope Based on Approximate l0 Norm Minimization

在核磁共振(NMR)波谱中，过长的数据采集时间会使化学以及分子生物学领域的高分辨率多维谱应用难以实现。传统的解决办法是使用随机非均匀采样代替奈奎斯特采样，但这样会使谱图质量受损。压缩传感的出现为此提供了更好的解决办法，合适的压缩传感重建算法可以通过很少的随机非均匀采样将谱图高质量的重建出来。目前压缩传感重建算法在NMR波谱领域已经得到了比较充分的应用，其中使用较多的重建算法是基于l1范数最小化的基追踪算法，为进一步改进重建效果，本文提出了两种基于近似l0范数最小化的压缩传感重建算法，主要成果如下： 一、介绍了一种基于近似l0范数最小化并可用于谱图重建的压缩传感重建算法，名为“平滑l0范数最...The problem of long sampling time often limits many applications of the multidimensional NMR spectroscopy in chemistry and molecular biology.

Solution-phase Synthesis of One-dimensional Silver Nanomaterials and Nanoseparation

多元醇法制备银纳米线已经被广泛研究。在这个体系中，考察了聚乙烯吡咯烷酮（PVP）分子量对银纳米形貌的影响，发现PVP分子量越大，所制备的银纳米线长径比越大。通过UV-Vis吸收光谱和原子吸收光谱分析表征发现，不同分子量PVP的还原能力的顺序如下：PVPK15>PVPK30>PVPK90，并且PVP的还原性会影响银纳米线的成核和增长。我们猜测，正是由于不同分子量PVP还原能力不同，进而影响了银纳米线的成核和增长，从而得出了PVP分子量越大，所制备的银纳米线长径比越大的实验结果。 在多元醇法制备银纳米线的基础上，发明了一种新型、无外加晶核的液相合成纳米银棒的方法。该方法以N-甲基吡咯烷酮为还原剂...Silver nanowires prepared by polyol process has been widely studied.

Satellite observation of the temporal and spatial variation of sea surface diurnal warming in the South China Sea

利用搭载在AQuA和TErrA卫星上的MOdIS(MOdErATE rESOluTIOn IMAgIng SPECTrOrAdIOMETEr)、AMSr-E(AdVAnCEd MICrOWAVE SCAnnIng rAdIOMETEr fOr THE EArTH ObSErVIng SySTEM)传感器测量反演的昼夜海表温度(SST),计算海表面日增温(SEA SurfACE dIurnAl WArMIng),分析南海海表面日增温的短期和年变动特征。受观测平台过境时间、传感器测量SST方式、反演算法等影响,MOdIS/AQuA计算的日增温幅度略大于AMSr-E/AQuA和MOdIS/TErrA,但在表征南海海表面日增温的时空分布特征以及变化趋势上三者并未见显著性差异。南海海表面日增温在时间分布上以冬季为最小,春季为最大;在空间分布上则是南部海域大于中部和北部海域,东部海域大于西部海域。春夏之交的吕宋海峡西北部尤其容易发生日增温事件。海表面日增温与太阳辐射、风速、云量等影响有关,其中风速与海表面日增温显著负相关。Satellite-derived sea surface temperature(SST) data from the MODIS(moderate resolution imaging spectroradiometer)/ Aqua, AMSR-E(advanced microwave scanning radiometer for the earth observing system)/Aqua and MODIS/Terra over the past ~10 years are analyzed to investigate the sea surface diurnal warming in the South China Sea(SCS).The results reveal that sea surface diurnal warming derived by MODIS/Aqua is slightly higher than that by AMSR-E/Aqua and MODIS/Terra, due to the differences in satellite transit time, sampling manner and retrieval algorithm, among others.However, there are no significant biases in terms of spatial and temporal distributions, and of the variation of sea surface diurnal warming over the SCS.The magnitude of sea surface diurnal warming in the SCS is the weakest during winter, and the strongest during spring.The magnitude is generally larger in the southern regions than in the central and northern regions, and is larger in the eastern regions than in the western regions.Northwest of the Luzon Strait, the sea surface diurnal warming tends to appear easily from late spring to early summer.It is suggested that the seasonal variation of sea surface diurnal warming in the SCS be affected by solar radiation, wind speed and cloud amount; among them, the wind speed is the most important factor with a significant negative correlation with the diurnal warming.福建省自然科学基金项目(2011J01278); 国家自然科学基金项目(40706041
