  1. With the decoupling average technique and high - temperature approximation, we obtain the graph of the system magnetization evolving, which clearly exhibit the critical slowing phenomena of xy model near the phase transition region

    運用退耦平均技術，在高溫近似下數值模擬得出的平均磁化強度的時間演化，清楚地展示了xy模型在相變發生區域內的臨界慢化現象。
  2. Their input capabilities are limited to a few buttons or numbers, or entering data takes extra time, as happens with a personal digital assistant ' s ( pda ) handwriting - recognition capabilities. they have less processing power and memory to work with, and their wireless network connections have less bandwidth and are slower than those of computers hard - wired to fast lans

    它們的輸入功能局限於幾個按鍵或數字鍵，或者像個人數字助理（ pda ）手寫體識別功能那樣，輸入數據要花很長時間，它們所擁有的工作處理能力和內存都較校比起那些通過計算機硬連線與快速局域網相連的連接，它們的無線網路連接帶寬較窄，速度也較慢。
  3. But, pso convergence ' s speed become slow in latter iterative phase, and pso is easy to fall into local optimization. at present, some scholars improve base pso mostly using 3 methods : disperse algorithm, increase convergence speed, enhance particle ' kinds. in the paper, i put forward 2 methods aiming at local best resutl but not whole best result. i modify base pso using the last method. some scholars put forward times initializations, so i select best result after circulating some times to be a parameter of formula. first, put particle into some small region, and ensure every region having one paticle at least. second, every region ' s particle has probability transfer other regions. although increase running time, enhance particle ' kinds, decrese the probability of convergence far from whole best result. nerms ( network educational resource management system ) is one of the research projects in the science and technology development planning of jilin province. the aim of nerms is to organize and manage various twelve kinds of network educational resources effectively so that people can share and gain them easily and efficiently, so as to quicken the development of network education

    但粒子群演算法仍存在如下不足:首先在多峰的情況下，粒子群有可能錯過全局最優解，遠離最優解的空間，最終得到局部最優解;其次在演算法收斂的情況下，由於所有的粒子都向最優解的方向群游，所有的粒子趨向同一，失去了粒子間解的多樣性，使得後期的收斂速度明顯變慢，同時演算法收斂到一定精度時，演算法無法繼續優化，本文對原始粒子群演算法提出了二點改進方案: 1 .演算法迭代到一定代數后，把此時找到的全局最優解當作速度更新公式的另一參數（本文稱之為階段最優解）再進行迭代; 2 .每次迭代過程中除最優解以外的每個粒子都有一定概率「變異」到一個步長以外的區域，其中「變異」的粒子在每一維上都隨機生成一個步長。
  4. It started out ok, but soon i noticed i was losing a lot of time at the slow sections due to the fact that i couldn ' t heat up the front tires

    剛開始還好，但馬上我注意到自己在慢速區域我損失了很多時間，這都是因為我無法讓前胎溫度上升。
  5. Many experiments are implemented, the results of which demonstrate the algorithm ’ s efficiency and stability. it overcomes disadvantages of the bp neural network which has slow convergence rate and is prone to fall into local extremum

    模擬和實驗結果充分表明了該演算法的有效性和穩定性，克服了bp神經網路收斂速度慢和易陷入局部極小的問題，為混沌時間序列預測運用開辟了新的應用領域。
