摘要：Triple-threshold CMOS technique provides the transistors that have low-, normal-, and high-threshold voltage. This paper describes a low-power carry look-ahead adder with triple-threshold CMOS technique. While the low-threshold voltage transistors are used to reduce the propagation delay time in the critical path, the high-threshold voltage transistors are used to reduce the power consumption in the shortest path. Comparing with the conventional CMOS circuit, the circuit is achieved to reduce the power consumption by 14.71% and the power-delay-product by 16.11%. This circuit is designed with Samsung 0.35 um CMOS process. The validity and effectiveness are verified through the HSPICE simulation.

摘要：对不同层次的学生进行同班教学是教育实践上常遇到的问题。目前,对小学课后汉语班的研究渐渐增多,但专门针对新老生水平差异的研究仍十分欠缺。在韩国的小学课后汉语班,学生可以随时报名参加课程,这一特点使得同一个班内的学生水平不一,教师无法对全班进行统一教学。鉴于此,研究在分层合作教学理论分析与实地调查的基础上,为课后汉语班课堂设计出了分层与合作的具体应用方法及课堂活动教案,并分析分层合作教学在韩国小学课后汉语班应用的效果。

摘要：为了研究金属丝网编织Kagome（WBK）热沉自然对流换热性能及其影响因素,对WBK热沉进行了大空间稳态自然对流实验研究。鉴于WBK热沉结构上强烈的各向异性,在不同面烧结铝基板进行总传热热阻测量。设计搭建了具有0°～90°任意旋转功能的实验台,对不同倾角下的自然对流换热热阻进行了测量。作为参照,选取与WBK热沉相同尺寸的光板进行了稳态自然对流热阻测量。研究结果表明：与光表面相比,WBK芯体具有更高的比表面积,可以有效地降低自然对流换热热阻,为光表面的42%左右。WBK芯体3个方向的对流换热热阻不同,显示出强烈的各向异性,具有适中堵塞率（迎风面积）的o-b方向具有最小的热阻。在0°～90°倾角内,WBK芯体在3个方向均存在一个最佳倾角,约为50°,相应的换热热阻最小。
