比较准确 ,我给你修改过的！！！已经很准确了！！!Multifunction digital clock is a "hour" and "minutes " and "seconds" displayed on the visual organ timing devices. It's time for the 24-hour cycle. Show that the largest number of 23:59:59, with the other school functions and timekeeping function. The system can also showed that the "month" and "day" .By the oscillator system, dividers, counters, decoding drives, figures show circuit, school circuit and timer circuit. Keywords : 555 timer; Frequency; Count; Digital display; School; The whole point timekeeping

Based on the communication network Direct3D visual simulation engine design and implementationtheVisual Simulation (Visual Simulation) is used to realize 3 d space information visualization technology, it has a realistic Simulation effect and convenient operation method, can well satisfy the new plane avionics system design paper designs and realizes an Direct3D based on the communication network visual simulation , in this paper the characteristics of the visual simulation and the programming essentials Direct3D brief analysis of selection, and expounds the main reason for the Direct3D. Secondly, put forward the visual simulation software, the total design project of the simulation software program and the software module partition the working process of the analysis of the various modules, explore the main functions and the relations among them. And then, based on the communication network of Direct3D visual simulation is the key technology of engine are analyzed and the study, introduces solutions discrete event simulation, Direct3D resource management and animation optimization and the mouse control technology, the key technology of the method. Finally, this essay discusses the Direct3D based on the communication network visual simulation software realization method, and in a more complex switched communication network as an example, the visual simulation, and the performance of the program was tested

哎！难度不小啊！ Along with the Internet technology and information technology's gradually maturing, the Internet scale expands day by day, network user quantity increases swiftly and violently, the Internet has applied in society's various trades and occupations, with people's routine work and the life relates closely in together. But emerges along with it electronic commerce has had the unprecedented influence to world economics' development. In the electronic commerce winding developing process, emerges is engaged in the electronic commerce in large numbers the new enterprise, some development are quite rapid. Tenable washed the valuable net in 2003 to take the Asian and Pacific biggest network retail merchant circle, was our country biggest auction website and on-line transaction platform. This article take washes the valuable net as an example, studies the website construction the process, makes the people to understand the website construction to the enterprise image demonstration and the promotion, the network servic
