    而長期以來，研究者都是從理論的角度，對學習方式和計算機輔助教學進行研究，從實證角度的研究乏善可陳，基於此，本文運用定量研究的方法，著眼于調查研究計算機輔助教學對大學英語學生學習方式影響.本文以重慶大學來自8個專業的353名學生為研究對象，根據他們接受計算機輔助教學的時間長短分為三個組，進行問卷調查，對數據進行整理和分析，得出以下結論：大學英語學生傾向于多種學習方式；在六種學習方式中，有五種學習方式並沒有隨著在計算機輔助教學的環境而呈現顯著的變化；但在聽覺型學習方式上，出現了下降；從對性別的比較中，男生和女生在幾種學習方式上具有顯著的差別;而計算機輔助教學環境對男生學習方式沒有明顯的作用，卻對女生的聽覺型，體驗型和小組型學習方式有顯著影響。
  3. When studying the network performance, flow control and resource provisioning of communication networks, traffic model plays a very important role. the recent studies show that the date network traffic is self - similar, so the markovian model, which describes telephone networks accurately, is not suitable for date networks. the self - similarity of the network traffic has severe impact on flow control and queuing analysis in date networks, therefore it has received significant attention. in this paper, g m 1 queuing model is used to analyze the queuing performance of generic variable length packet networks for the first time. the self - similar traffic is generated by multiplexing a large set of independent pareto heavy - tailed interarrival on off sources. the simulation results show that the heavy - tailed traffic results in queuing performance deterioration for variable length packet networks, which is in accordance with the analytical results for atm switches
