Firstly introduced the basic theory and method with which the analog signal can be convert to digital form, including sampling theory and course, quantification and quantification error, coding, beside those we discussed some applications of sampling technology, the reason of frequency mixture and the method to eliminate it chapter 4 introduced analog mux - switch, for the reason of simpleness we only introduce it briefly
從第3章開始，對數據採集的基本理論進行討論，首先介紹了模擬信號數字化處理中的基本理論、方法，包括采樣過程、采樣定理、量化與量化誤差、編碼，還討論了幾種采樣技術的應用、頻率混淆產生的原因及消除措施。第4章，介紹了模擬多路開關。 -
Throughputs of adaptive modu - lation, adaptive coding, and joint adaptation schemes are analyzed, and optimal switch - ing threshold of snr is obtained. in comparison with non - adaptive harq, adaptive schemes can get much higher throughput in the given cell. among the three adaptive schemes, adaptive modulation is t
分析了自適應調制、自適應編碼和聯合自適應方案在小區中的流量特性，得到了最優的切換門限，比較了自適應與非自適應harq的流量，以及三種自適應方案的優劣，其中自適應harq流量特性明顯好於非自適應harq 。 -
In the session of the analysis and coordination of those static data of fittings, on the basis of the reformed data of fittings, the paper establishes both a scientific classifying principle and also a rational coding system, which resolved the problem of the fittings - data - standardization. in order to control the actuality and the rate of overlapped codes, the paper has designed data - preparation programs and data - switch programs and data - checking ones through database programming technologies
在對配件靜態數據的分析整理及實施技術的研究中，基於重構后的配件數據，建立了科學合理的分類原則和編碼體系，解決了配件數據的規范化和標準化問題，採用數據庫編程技術，設計了數據準備、轉換和檢查程序，實現了對數據準確性和重碼率的控制。 -
2. the design of computer control system by combining plc with technical computer came ture, and discussed the problems of plc hardware configuration, plc control software and the software design of 3. design and tailor the module of communication translation from profibus to rs232 / 485, and discussed the methods of use and programme. it fingures out the communication translation between profibus - dp simens commen used communication protocol and rs232 / 485 hardware equipment. it makes the commen equipment ( for example : the module of radio communication, the module of coding cable position detection, and so on ) using rs232 / 485 can be used as substation to switch in the system of simens, and extensions the range of the system of simens plc
3 、設計製作profibustors232 / 485通訊轉換模塊，並對該通訊轉換模塊的使用及編程方法進行了討論。解決了西門子常用通訊協議profibus - dp到rs232 / 485協議硬體設備之間的通訊轉換問題，使採用rs232 / 485通訊的通用器件（如mds無線通訊模塊、編碼電纜位置檢測模塊等）可以作為profibus - dp分站接入西門子plc系統中，大大擴展了西門子plc系統的應用范圍。
