形式定义 meaning in English
formal definition
Examples
- 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。
