简介：参加中职技能大赛有利于激发学生学习兴趣、提高学生学习水平,但任何一场中职技能比赛都离不开《电子技术基础》课程的学习、应用。然而《电子技术基础》内容庞杂、概念抽象、电路结构复杂,再加上中职学生的学习基础普遍不扎实、学习自觉性普遍较差,对这门课程的学习愈加困难。文章利用EveryCircuit对复杂电路进行仿真,使原本庞杂的内容更加清晰、抽象的概念更易理解、复杂的电路结构更加明了。学生在学习中还能直观的观察到动态电压和电流的动画,更好地激发学生学习的兴趣,调动学生学习的积极性。

简介：这篇文章介绍一台对称的self-electrooptic效果设备(S种子)的基本结构，并且使用Kirchoff的当前的法律和一个完全相等的电容的模型，到分析S-SEED的开关特征。线性近似和N片断近似被利用获得S-SEED的电压时间(vt)和特征。理论分析被模拟验证，并且结果证明S-SEED的开关时间的精确能与线性近似在应用满足要求。而且，模拟把S-SEED的开关特征与不同输入力量和输入对比比率作比较，它表明那增加的输入对比比率是改进S-SEED的开关特征的一个有效方法。

简介：密文政策基于属性的可查找的加密(CP-ABSE)能为数据分享和检索完成有细密纹理的存取控制，并且安全deduplication能由消除副本拷贝节省存储空间。然而，有很少策划支持可查找的加密和安全deduplication。在这份报纸，支持安全块级的deduplication的一个大宇宙CP-ABSE计划在混合的云机制下面被建议。在建议计划，在密文被插入到花蕾过滤器树(BFT)以后，私人云能由匹配标签高效地执行有细密纹理的deduplication，并且公共的云能用同构的可查找的方法并且关键词匹配高效地寻找。最后，建议计划能在选择分发攻击下面完成隐私块级(PRV-CDA-B)固定deduplication并且隐藏火柴(MC)可查找的安全。与存在计划相比，建议计划在同时支持有细密纹理的存取控制，块级的deduplication和有效搜索有优点。
