The CDF Date Acquisition System for Tevatron Run Ⅱ

The CDF experiment at the Fermilab Tevatron has been significantly upgraded for the collider Run Ⅱ,which started in march 2001 and is scheduled to alst until 2006,Instantaneous luminosities of 10^32cm^-2S^-1 and above are expected.A data acquisition system capable of efficiently recording the data has been one of the most critical elements of the upgrade.Key figures are the abilitity to deal with the short bunch spacing of 132ns.event sizes of the order of 250kB,and permanent logging of 20MB/s ,The design of the system and experience from the first months of data-taking operation are discussed.

浅议怎样做好中学物理静电实验

中学物理静电实验是物理老师感到最难做好的实验之一,有时在实验室准备时能做成功,一上讲台就莫名其妙地不灵了.因此,有些老师很怕做静电演示实验,特别是在阴雨天气.影响静电实验成败的因素很多,但归纳起来关键因素是"绝缘"、"环境条件"、"实验装置与方法".     

插层化合物LiV2O4的制备与实验研究

用化学方法从层状化合物LiVO₂中引出0.5个Li后得到Li_0.5VO₂,再经过低温真空热处理制备出尖晶石结构化合物LiV₂O₄,类似地处理Li_0.465VO₂,得到缺Li的Li_0.93V₂O₄,LiV₂O₄和Li_0.93V 关键词：     

单片机与计算器相结合在物理实验中的应用

单片机或单板机在软件设计上,一般使用汇编语言。用这种语言编写复杂的运算程序,特别是函数运算程序往往有一定难度。而计算器却有很强的计算功能。能否两者结合来完成实验数据的采集和运算处理呢?笔者对此作了研究和实验,效果是令人满意的。
