对等网络P2P系统安全问题的研究

近年来对等网络P2P(Peer-to-Peer)的研究主要集中在如何提供有效的查找系统。这些系统在正确执行时确实具有良好的性能，但却没有考虑到行为不正确的节点攻击。本文主要研究通过阻止正常节点找到数据的攻击，提出了一种在对等网络P2P环境下的基于安全性令牌的安全模型。     

燃煤型氟骨症患者血清钙、磷及碱性磷酸酶的变化

目的:了解燃煤型氟骨症患者血清Ca、P和ALP的变化。方法:分别测定99例燃煤型氟骨症患者和61例非病区健康人群血清Ca、P和ALP水平。结果:氟骨症患者血清Ca(2.12±0.24mmol/L)明显低于健康对照组(2.51±0.14mmol/L),血清P(1.24±0.41mmol/L)和ALP(90.22±29.21U/L)明显高于对照组(分别为1.09±0.28mmol/L和73.64±23.93U/L),差异均具有统计学意义(P<0.01)。结论:在排除其他代谢性骨病的条件下,血清Ca、P和ALP可作为氟骨症辅助诊断的生化指标。     

Beliefs about Language Learning Held by Pre-service Teachers:A case study

Language learning beliefs play a very important role in influencing learners’ attitudes,motivations and also shape their experiences and actions in classroom.Successful learners develop insightful beliefs about language learning process,their own abilities and the use of effective strategies.However language learning beliefs can be different because of individual learner differences and contextual diversity.This study aimed at exploring beliefs about language learning held by pre-service teachers.159 pre-service teachers majoring in English at Qianan Normal College for Nationalities participated in the study.A 34-item questionnaire adapted from Horwitz’s(1987) BALLI was used to collect the data.The results were reported and discussed from the following five aspects:1) beliefs about foreign language aptitude,2) beliefs about difficulty of language learning,3) beliefs about nature of language learning,4) beliefs about learning and communication strategies,and 5) beliefs about motivation and expectations.Suggestions on pedagogical implications and for future research were also indicated.
