小心“牙渍”必报

人们常用“睚眦必报”来形容那些即使是受了像瞪了自己一眼那样小的仇恨，也要报复的心胸狭窄的人。言下之意，人应该大度，少对一些细枝末节斤斤计较。以此推理。人们认为的“牙痛不是病。就更不应该过多关注了。然而，现代医学的一些研究却表明：牙病看起来是“小毛病”。但危害远远超过牙齿本身。甚至连牙上的“渍”——细菌、牙石等也有可能导致多种疾病。     

LIGA工艺的发展及应用

介绍了LIGA(lithographie,galvanoformungandabformung)技术以及在此基础上开发出来的准LIGA(like－LIGA)技术、SLIGA(sacrificialLIGA)、M2LIGA(movingmaskLIGA)技术和抗蚀剂回流LIGA(PRLIGA———photoresistreflowLIGA)技术等。利用这一系列LIGA技术,可以生成具有高深宽比的复杂微结构,如微尖阵列、球形曲面、活动部件等,能较好地满足MEMS发展的需要。最后指出了目前这些方法存在的缺陷。

Micromagnetic simulation of FeCo write head in perpendicular recording hard disk drives

The single-pole tip (SPT) heads made of the high saturation FeCo ferromagnetic metals are crucial for the actualization of ultrahigh density perpendicular recording. The effective head field distribution in the medium is of key importance for the design of the SPT head, which would be analyzed by micromagnetic simulations in this work. Two 3D micromagnetic models of the SPT head were established to select a more appropriate method of modeling, with a magnetostatic image effect or a real soft magnetic material to model the image of the SPT head in soft under layer (SUL). The results from these two designs were tested and compared to the ideal head field calculated by the Jacobi finite element method (FEM); and the design with the real soft magnetic material as image was proved suitable for simulating the ultrahigh density perpendicular recording write head.     

Improving Information Quality Through it Alignment Planning: A Case Study

This article describes how a medium-sized, Midwestern power company implemented an IT alignment planning process. the IT alignment planning process was a successful four-year activity that involved, first, a pilot implementation and then a companywide implementation of the IT alignment planning process. Designed to be flexible and to dovetail with corporate strategic planning processes, IT alignment planning achieved acknowledgment and approval in all divisions of the company. the IT alignment planning process improved and facilitated communication on IT and IT projects throughout the company, from the executive level to the operational level, and brought the IT and client units closer together.
