开放式基金,大众理财的首选

开放式基金是投资基金一个主要品种，指发行总额不固定，基金单位总数随时增减，投资者可按基金报价在国家规定的营业场所申购或者赎回基金单位的投资基金。由于开放式基金的某些特点，所以它广受投资者的欢迎。本文将着重向投资者介绍开放式基金的理财特点以及如何投资于开放式基金

私募基金监管模式及其对中国的借鉴

私募基金投资具有极大的风险性决定了其必须依靠一些较为细致、可操作性强的监管措施来保护投资者的权益。在对以美、英及台湾地区为代表的基金监管模式及我国现实市场的理性分析基础上 ,我国私募基金的监管模式应主要向较为严格的美国监管模式学习 ,并在监管的重点放在投资者资格和人数限制、管理人与发起人条件、托管人职能的规定、托管人职能的规定与信息披露规定和风险揭示等法律规范方面

Research on Image Fusion Based on Polarization of Haze

利用光的偏振特性,即不同偏振图像的相关性和信息上的互补性,提出一种基于薄雾偏振特性的图像融合方法,可以将两幅不同偏振方向的薄雾图像融合在一起,从而有效地去除薄雾,得到更加清晰的景物图像.实验结果表明,该方法具有较好的去除薄雾效果.This paper researches the theoretical basis for removing haze by using polarization properties of light and proposes the image fusion method based on the theoretical.Meanwhile,we optimize this algorithm.By using polarization properties of light,which means using the information of the polarization-based images′ correlation in time and space and complementary with each other,we can get a clearer image compared to the original polarization-based images which are captured from the same place and different polarization angles.The results of the experiments prove that the algorithm has a good robustness and the clarity of the image fused is increased significantly.福建省自然科学基金项目(2009J01301;2009J05087

The Experimental Analysis of the Performance of Share Prices of the Punished Listed Companies

本文利用目前国内学者没有考察过的上市公司被处罚的实例,利用事件研究法考察信息公布前后样本公司股票价格和股票交易量的反应,以求从另外的视角来考察我国股票市场的半强式有效性。 This article tests the semi-strong efficiency of china’s s stock market through examining the change of stock prices and stock volumes of the listed corporations that had been punished or criticized. The method used in this article is event study. The result is that china’s stock market hasn’t come to the semi-strong efficiency

径向调制永磁齿轮磁极数量对传动特性的影响研究

对于永磁齿轮，每一个传动比都可以由主、从动磁极对数量的若干种组合方式来实现。为此，以i=5和相近的传动比为例，选取主、从动磁极对的数量为2/10、3/15、……、7/35共6种组合方案和两组验证对比方案（每组各6种），应用有限元仿真技术，研究了磁极对数量对输出转矩和传动效率的影响。结果表明，输出转矩随磁极对数量的增加呈二次曲线规律变化，且峰值出现在主动磁极对数Ph=4处；而传动效率基本也呈二次曲线变化规律，在Ph=4~7处出现较大的值，但是变化不大。综合考虑输出转矩和传动效率，当传动比在i=5附近时，选取主、从动磁极对数量的组合方案Ph/Pl=4/19，可以获得较好的传动特性

Recent Advances in Big Defensins of Marine Invertebrates

Big defensins are cysteine-rich cationic antimicrobial peptides(AMPs)formed by serially connecting the N-terminal hydrophobic domain with the C-terminal beta-defensin-like domain.These domains have different antibacterial activities.Moreover,big defensins have conserved salt-stable antimicrobial activity and the N-terminal domain can drive the self-assembly of big defensins into nanonetworks that entrap and kill bacteria.So far,big defensins have been mainly found in the innate immune system of invertebrate animals and amphioxus that is a primitive chordate holding a key phylogenetic position bridging from invertebrates to vertebrates.Moreover,the C-terminal domain of big defensins has similar structure and bioactivity to the beta-defensin of vertebrates,which has aroused interest in investigating the biological evolution and function of defensins and the evolution of the immune system in species related to defensins.Based on the progress that has been made in the identification and characterization of big defensins in recent years,herein we present an integrated review of the molecular structures and evolution of big defensins,together with their antibacterial mechanism and expression regulation as well as their application prospects in the fields of aquaculture and aquatic product safety and in the development of new antimicrobial drugs.This review will provide a reference in the application of big defensins
