In addition, these methods rarely consider the case of multi - stage preloading. several studies has been made to solve these problems : ( 1 ), an error processing is present to manage settlement data. based on fairing filtration theory, a fairing program is compiled to fair the observed data. ( 2 ), according to classical consolidation theories, an analysis model of settlement data has been built under conditions of multi - stage preloading

為改善上述缺點，本文進行了以下的研究工作：在忽略耗能器附加質量的基礎上，推導出適用於耗能減震結構的攝動法，減少振型分解法在迭代計算過程中的工作量，加快計算速度；針對運動方程的強行解耦所產生的誤差，根據攝動法原理，對其進行一階攝動修正；為消除強行解耦振型分解法用於非比例阻尼結構分析時產生的誤差，引入狀態空間對系統進行復模態分析，並改進了基於復模態理論的、適用於非比例阻尼結構設計的雙反應譜方法；對于耗能器的數量和位置優化進行了一些探討和研究。 -
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。
