Abstract : bridge function and generalized bridge function are all three - valued function, and are made by initial sequence according as copied or shifted ways. they include some familiar orthogonal function of non - sine, such as walsh function. this paper briefly introduced some research advance on this subject, emphasized to introduce the copy theory and generalized copy method. the process of making ( generalized ) bridge function, its property and application, were introduced briefly
文摘:橋函數和廣義橋函數均為三值函數系，都是將初始序列經復制方式和移位方式變換后而形成的.它們包括了一些常見的非正弦正交函數，如沃爾什函數和方波函數等.簡要介紹了近10年來北京航空航天大學通信與電子系統博士點在非正弦正交函數方面研究的一些新進展，重點介紹了復制理論和廣義復制方法，橋函數、廣義橋函數的復制生成方法、性質及其應用等專題Use wavelet analysis dwgs of shanghai, tianjin, xian and wuhan by the time 1470 to 2000. discuss the abrupt situation. at last, we use the arithmetic of lemper - ziv complexity to resolve the complexity of shanghai, tianjin, xian and wuhan
