Feed翻译工具:Mloovi,feedlanguage,blastcasta,Yahoo Pipes

 
很多朋友因为获取信息的需要,订阅了不少外语博客,当然这里的外语不单指英语,还包括其他语种诸如德语法语日语韩语等等;另外也有很多有影响力的博客,访客除了来自国内之外,还有相当一部分来自于世界各地。RSS Feed 作为最重要的Blog阅读方式,实现对RSS Feed的翻译成为必要,Google reader 也提供了 feed 翻译功能,在文件夹设置中选择”翻译到我使用的语言”即可。而微博客的兴起,因为有些提供了 feed 导入功能,很多人将自己的 RSS feed 导入自己在国外微博客的个人页面上,表面上看似乎能够全球范围内推广自己的博客,然而实际上因为语言不通的缘故而收效甚微。下面介绍 3 款 feed 翻译工具:Mloovi 、Feedlanguage 和 blastcasta,或许能给大家提供一点方便。
Mloovi 和 Feedlanguage 都采用Google Translate的翻译引擎,Item 链接都转换成了对应的Google Translate的翻译链接,因为是基于机器的翻译,所以翻译结果有时有失精准也在所难免。

What’s the difference between the net change theorem and the evaluation theorem?

I’m taking high school AB Calculus.
I know the Evaluation Theorem states:
The definite integral from a to be of f(x) is the anti-derivative of b minus the anti-derivative of a. Doesn’t the Net Change Theorem say virtually the same thing?

what is the impulse of the net force applied to the ball during the collision with the floor?

A 0.660-kg ball is dropped from rest at a point 2.10 m above the floor. The ball rebounds straight upward to a height of 1.20 m. Taking the negative direction to be downward, what is the impulse of the net force applied to the ball during the collision with the floor?
