  1. In this thesis, abundant statistical data are contained, two methods are employed to give a positive analysis on the elasticity of demand ( eod ) of i & e in china during the period from 1990 to 2001 from the following three aspects : firstly, regression analysis is applied to calculate the average eod of the general i & e. generally speaking, the export is rich in price eod while the import has a poor one. in addition, the absolute value of the sum of these two kinds of elasticity is higher than 1, which accords with marshall - lener condition and proves that devaluation of rmb should be helpful to improve the trade balance. suggestion is further provided such as cutting off producing cost of export, improving technology and implementing strategy of import substitution to improve trade balance

    本文運用豐富的統計數據資料、兩種方法、從三個層次實證分析了1990 - 2001年我國進出口商品的需求彈性：首先，運用回歸分析法計算總體進出口商品的平均彈性，得出我國出口商品總體富有價格彈性，而進口商品總體缺乏價格彈性，進出口需求價格彈性之和的絕對值大於1 ，符合馬歇爾?勒納條件，人民幣貶值有助於改善貿易收支的結論，並提出降低出口商品生產成本、提高生產技術水平、實施進口替代戰略來改善貿易收支；其次，運用彈性定義法逐年計算約100種主要出口商品和約50種主要進口商品的總體需求價格彈性，對其結果進行分析，進一步驗證了前述結論；再次，運用彈性定義法逐年計算農產品、鋼鐵、汽車、醫藥等五大類八種商品的進出口需求價格彈性，根據其不同的分佈狀況，聯系實際經濟情況，提出相應的匯率、價格及產業政策以改善貿易收支。
  2. 3 a novel recursive least - square ( rls ) blind space - time receiver algorithm based on the constrained condition, which can completely avoid the matrix inversion introduced into by constraints ( comparing with the normal rls ), is proposed for multi - path slow fading cdma channels. the computational complexity of this method is not only lower than that of the normal rls, but also lower than that of both lms and ls blind space - time receiver methods that are realized based on the rosen ' s gradient projection. and the speed of convergence of the presented rls blind space - time receiver algorithm is better than that of both lms and ls blind space - time receiver methods

    3 、針對多徑慢衰落通道下ds - cdma盲空時接收機中線性約束二次規劃問題提出一種新的遞歸最小二乘演算法，該演算法完全避免因約束而引進的矩陣求逆運算（相對于常規的遞歸最小二乘演算法） ，不但運算量比常規的要低，而且比基於rosen梯度投影實現的最小均方（ lms ）與最小二乘盲空時接收機演算法還低，且收斂速度比基於rosen梯度投影實現的最小均方（ lms ）與最小二乘盲空時多用戶檢測都好，將提出的新的遞歸最小二乘演算法與提出的數據選擇方案結合起來可以進一步降低其運算量，具有很大的實用價值，最後通過模擬實驗進一步分析了其性能。
  3. Combined with the data - selected schemes proposed, the computational complexity of this method can be lowered. the performance of the presented rls method is analyzed by simulations, and it is shown that this method is interesting for application. 4 time - selective channel signal model based on multipath - doppler diversity representation is given in multi - path fast fading channel, and rls space - time receiver algorithm based on time - varied constraint condition is presented and the computational complexity of this method is analyzed

    4 、針對多徑快衰落通道下的ds - cdma系統，給出了基於多徑-多譜勒觀點描述的1百安電弓卜科東兔j憶學協士學位論文時間選擇性通道的信號模型，提出了基於變約束條件下的遞歸最小二乘空時接收機演算法並分析演算法的運算量，最後通過模擬分析了所提出的方法的性能。
  4. With the coming of information age, more and more people realize the importance of information. useful information hidden in plenty of data needs mining energently. the technology of data mining arises and develops unders such circumstance. the main tast of data mining is to extract or mine the useful information from the data. we can get great amount of data from the computer transaction every day. the data is very useful for us to make decisions on management. the paper concludes and introduces association rule about its concept, sort, model and step for mining the data, measure and some basic algorithm on the basis of the at research. at the same time, we analyse hopfield - network ' smodel, character, energy - function, movement - equation and so on. moreover, to the requirement of the system of information of computer - saling, we have done the following and there are good result. fisrt, considering the weight and constraint, we propose the algorithm for the weighted and constraint association rule
