  1. With those purposes, the paper discusses the social and economic basis of auditory of circulations with systemically reviewing the origin, development and internationalization of abc and bpa. an analysis on the definition, significance and characteristics of auditory of circulations is also done with a full perspective on the current index systems and series of regulatory regime both on abc and bpa ( us abc and bpa international as the two optional samples ). furthermore, the author tries to find out a tentative solution on the issue of the system construction of auditory of periodicals " circulations with the analyses of the current social and economic situations, especially the development of the periodical industry and advertising industry in china at the beginning of 21st century

    本文對abc和bpa的起源、發展和國際化歷程做了系統考察，在此基礎上分析發行量認證體系存在和成長的社會經濟基礎；以美國發行量認證署（美國abc ）和bpa國際媒體認證公司（ bpainternational ）這兩個認證機構為樣本，對兩種認證體系的現行指標體系及具體管理制度等微觀層面作全面透視，分析發行量認證的內涵、意義和特徵；針對中國當前的社會經濟現狀，尤其是中國期刊產業和廣告業的發展格局進行剖析，解答中國要不要引入期刊發行量認證體系以及中國引入期刊發行量認證體系的初步解決方案這兩個問題。
  2.

  3. According to different mechanisms, there exist several types of resonance, including the bridge resonance induced by the periodical actions of moving load series of the weights, centrifugal forces and lateral winds of vehicles, the bridge resonance induced by the loading rates of moving load series of vehicles, the bridge resonance induced by the periodical loading of train vehicles excited by rail irregularities, wheel flats and hunting movements, and the vehicle resonance induced by periodical actions of the regular arrangement of bridge spans and their deflections

    根據發生機理的不同，車橋系統可能發生幾種不同形式的共振，包括由車輛重量、離心力、橫向平均風荷載等形成移動荷載列的周期性動力作用引起的橋梁共振，由移動荷載列加載速率引起的橋梁共振，由軌道不平順、車輪扁疤、輪對蛇行等周期性加載引起的橋梁共振；由橋跨的規則性排列及其撓度的影響，對移動車輛形成周期性動力作用使車輛出現的共振。
  4. In chapter 4, the performance of asynchronous systems with multilevel spreading codes based on periodical repetition of quantized chaotic time series is presented, focusing on the ds - cdma systems. some computer simulations for four kinds of chaos - based sequences are given to examine the results that chaos - based sequences outperform the classical spreading sequences ( maximum - length and gold sequences ) and the chaos - based sequences from the chevbyshev maps ( k = 3, 7, 11 ) is the best among them. as the result of these optimization effort, two design means toward sequences optimization are obtained, in which one is based on the entropy theory, the other is on minimizing the average possible error

    3 、本文的第四章分析了混沌序列的各種統計特性，著重研究混沌序列作為混沌擴頻序列在ds ? cdma系統中的抗擾性能，對不同的混沌擴頻序列和典型的擴頻序列進行了模擬，從模擬結果中可知，混沌擴頻序列的性能可以與典型的擴頻序列媲美，經過優化設計的混沌序列特性優于典型的擴頻序列；在混沌序列中， chebyshev混沌序列（ k等於3 . 7 . 11 … …時）是最佳序列之一。
