The general requirement of communication system and the application potential in secure communication are expatiated. the chaotic secure communication methods home and abroad are also summarized, including chaos spread spectrum communication, chaos key - shifting, chaos parameter modulation, chaos masking, chaos cdma. the exiting problems and development direction are also pointed out respectively
介紹了混沌學的發展過程和意義，闡述了通信系統的一般要求和混沌在保密通信中的應用潛力，綜述了國內外現有的混沌保密通信方法，其中包括：混沌擴頻通信，混沌鍵控，混沌參數調制，混沌掩蓋，混沌數字碼分多址等五大類，指出了各自存在的問題和發展方向。 -
As a complex nonlinear dynamics behavior, chaos is a general phenomenon in nature and is one of the most important discoveries in the 20th century later. chaos, which is generated by non - linear dynamical system, possesses many unusual characteristics and these characteristics enable chaos to have a great charming prospect and practical value in secure communication field. recently, chaotic communication has become a new and promising subject, so this dissertation selects it as research direction, and analyses emphatically the applications of chaos in cdma communication system. the main works are as follows : ( 1 ) chaotic phenomena and its related problems are summarized, and these problems, such as the relation of spread - spectrum code in cdma communication system and chaotic sequences, and the relation of chaotic synchronization and system secret performance, are discussed
混沌是一種特殊復雜的非線性動力學行為，也是自然界普遍存在的現象，被認為是二十世紀末期最重要的科學發現之一。有確定性非線性動力學系統產生的混沌具有許多奇異的特性，顯示了混沌在保密通信等領域有著誘人的應用前景和重大的實用價值，目前，混沌理論在通信中的應用是一個全新的前沿課題。本文以此作為研究方向，著重分析了混沌在碼分多址通信系統中的應用。 -
The land concentration to the more specialized farming household and agribusiness satisfied the needs of appropriate land scale operations and improved the international competence of agriculture, but in a few areas the circulation is still spontaneous and in chaos. the peasants " contracted land rights to use have been often encroached. how to make the circulation of rural land right to use in a right and orderly direction and set up a circulation system to be truly " volunteer, by law, paid " is a urgent problem to be solved
當前不少地方正推進土地使用權流轉工作中進行了一些積極探索，土地向種田大戶和農業企業集中，滿足了土地適度規模經營的需要，提高了國際競爭力。但相當一部分地區還處于自發式的流轉或無序狀態，農民的土地承包經營權益仍然不斷受到侵害，如何使土地使用權流轉朝著健康、有序的方向發展，建立起真正的「自願、依法、有償」的土地流轉機製成為迫切需要解決的問題。 -
