We have proved that the properties of convex risk measures can be characterized by that of the acceptable set . further more , as a case study , we considered convex measures of risk defined by the notion of bounded shortfall risk 结果证明凸性风险测度和与其相伴随的可接受集之间可相互表出的关系，进一步，作为例证研究，本文考察了以有界亏空风险的形式定义的凸性风险测度。
In this part , the author mainly discusses the following issues respectively : object of bearing punishment , active object , pattern of possession , and conduct category of possession , sphere of possessory offences . chapter 4 discusses whether the crime of huge unidentified property belongs to possessory offences 本文仅论述本罪是否属于持有型犯罪，作者认为虽符合持有型犯罪的形式定义，也与立法中的其他持有型犯罪有颇多不同，但仍应属持有型犯罪的研究范围。
In the second chapter , some relative basic theories in wavelet analyse is first proposed in brief , involving the cause of develop - ment of wavelet theory ( that means its good ) , the definition of continuous wavelet , discrete wavelet and dyadic wavelet and the multiresolution analysis for constructing orthogonal wavelet . then the biorthogonal wavelet and method of its application for image compression is discussed . based on the research of genetic algorithm for the constructing method of wavelet filters , the method of con - structing optimal wavelet filters for the specific image compression is put forward , so the problem about image optimal compression is solved successfully with the combination of genetic algorithm and wavelet used in image compression 在第二章首先简述与图像压缩相关的小波分析基础理论知识，涉及到小波得到发展的原因及其优点，连续小波，离散小波，二进小波具体形式定义，以及构造在正交小波的多分辨分析。然后阐述了紧支撑双正交小波及其在图像压缩具体应用方法之后，基于遗传算法对小波滤波器的构造方法进行的研究，提出了解决对任意特定图像进行压缩处理所需要的最优小波滤波器的构造问题，从而将遗传算法与小波压缩有机结合起来实现了图像的最优压缩。
Abstract : in this paper , the formal definition of composite objects was presented . semantics of composite object was specified and related to object - oriented concepts . then the semantics , creation and deletion of composite object were illustrated in terms of schema definition , which shows the integration of composite objects . meanwhile , the approach of implementing composite objects , including enforcement of the semantics of composite objects and its physical clustering , was also indicated 文摘:把复合对象和面向对象的概念联系起来，在复合对象的形式定义后，指定复合对象的语义，然后根据模式定义来说明复合对象的语义，以及复合对象的创建和删除.展示了复合对象数据整体性.同时还指出了实现复合对象的方法，包括复合对象语义的强制和物理聚集
The paper abstracts out the palmprint mainline characteristic owing to palmprint image gradation by the gray value characteristic property method , defining the online palmprint characteristic space with the form of the polar coordinate and compressing the dimension , at last we use the neural network to accomplish the design of identification authentication system with the on - line palmprint as the mating algorithm . based on this , a fast and reliable system of identification authentication can be built 采用基于掌纹图像灰度特性的方法提取出掌纹的主线特征,以极坐标的形式定义在线掌纹的特征空间并降维处理,最后用神经网络作为匹配算法完成在线掌纹身份验证系统的设计,以此为基础建立了快速、可靠的新型身份认证系统。
His idea is based on the fact that the pivot of the soft wireless structure is to put the broad band a / d and d / a conversion near to antenna by all means , and to define the functions of the transmitter - receiver as many as possible in the forms of software ( namely realized by software ) . the technology of background signal simulator puts the focus on the methods used to realize the software , namely to exploit the functions of the hardware ( for example , dsp fpga or asic ) through the idea of software design , and to produce ( realize ) wireless signals by high speed lsi and software programming 1992年5月的全美电信系统年会上， mitre公司的资深科学家joemitola首次给出了软件无线电的定义，他认为：软件无线电的组成架构的中心点是将宽带模?数( a d )和数?模( d a )转换器尽可能地靠近天线，将尽可能多的电台功能以软件的形式定义(即用软件来实现) 。背景信号模拟器所采用的技术集中体现在软件无线电技术，即用软件化设计去开发硬件(如dsp 、 fpga 、 asic )功能，采用高速大规模数字集成电路、软件编程的方法产生(实现)各种无线电信号。
