word快速输入数学公式

微软的word可以说是最常用的办公软件,word的功能更是博大精深,其实有很多技巧可以帮助我们简化操作,提高输入速度。

相信很多理工科的朋友都有这种体会,输入数学公式是一件非常令人头疼的事情。即使使用MathType等其他工具也快不了多少,用鼠标点啊点啊的。自从word2007开始,公式可以采用线性输入的方法,然后配合使用快捷键,输入公式跟输入文本一样轻松。

例如,在word2007以及2010中,要输入下面的公式:

clip_image002[6]

按下 Alt+= ,然后在键盘输入

[-ℏ^2/2m d^2/(dz^2 )+U(z) ]ξ(z)=Eξ(z)

然后回车即可。然而一些特殊字符ℏ,ξ的输入还是比较麻烦。通过定义快捷键,例如定义Alt+H,输入ℏ,定义Alt+A,输入α,这样输入特殊符号就快多了。

通过这两个技巧,轻松输入数学公式。

我在SAE上面部署了我自己的wordpress

wordpress是一个开源的博客系统,可以到 http://www.wordpress.org 下载源代码,直接部署就可以使用,非常方便。Google最先推出了Google App Engine服务,这是一个非常酷的服务,提供了免费的主机服务。Google支持java和python。Sina模仿谷歌也推出了Sina App Engine服务(新浪还处于研究阶段,还不太稳定),sina使用的是php架构。本人认为新浪有一点做的比谷歌好,就是新浪做了一些模板性质的应用,只要你点击一下鼠标,即可完成部署,这对于像我这种零基础的真是个好消息。新浪做了一些个性化的应用包括针对SAE调整的wordpress、Teamtoy、微博Oauth、iSaid(我研究了半天,还是乱七八糟的错误)。

wordpress的确是一个非常的博客系统,过去只是用现成的,还没有深刻的感受。部署过程十分简单,填写一些个人信息,就可以完成。通过新浪的MYSQL服务可以非常方便的管理。
