阿基米德

Archimedes, you are late again. Don't tell me that you were locked again in the bathroom.

阿基米德，你又迟到了，别告诉我你又被锁在卫生间了。

Starting on July 26th, researchers at the Stanford Synchrotron Radiation Laboratory in California , led by Uwe Bergmann, will attempt to read the final pages of the oldest known manuscript of Archimedes's work, the Archimedes palimpsest.

在尤。伯格曼的带领下，加利福尼亚的斯坦福同步加速器辐射实验室的研究人员将于7月26日尝试阅读目前所知的最早的阿基米德著作的手稿-《阿基米德》重写本-的最后几页内容。

After 3800 Death of the World's top math problems -- Ruler as "arbitrary angle trisection, turning round to square, fold the cube, as is 7-gon, as is 9-gon, as are 10 side of the form, as are 13-gon," The world, where people called mathematicians have challenged the "seven problems" Archimedes Newton Gauss, etc., Are hard to understand in the end.

历经3800年世界顶级数学死题——尺规作&任意角三等分、化圆为方、倍立方体、作正七边形、作正九边形、作正十一边形、作正十三边形&，全球，凡称得上数学家的人都曾挑战过这&七大难题&，阿基米德、牛顿、高斯等等，均以不得其解而告终。

Now turn thy thoughts to the other kinds of men. To that place then we must remove, where there are so many great orators, and so many noble philosophers, Heraclitus, Pythagoras, Socrates; so many heroes of former days, and so many generals after them, and tyrants; besides these, Eudoxus, Hipparchus, Archimedes, and other men of acute natural talents, great minds, lovers of labour, versatile, confident, mockers even of the perishable and ephemeral life of man, as Menippus and such as are like him.

现在把思绪转向其他一类人，进入这样一个世界，在这里有如此多杰出的演说家、如此多高贵的哲人，赫拉克利特、毕达哥拉斯、苏格拉底，如此多昨日的英雄，以及如此多跟随他们的将军，还有那些暴君，除了这些，还有欧多克索斯，希琶斯，阿基米德，以及其他具有真正自然天赋者、具有伟大思想者、热爱劳作者、多才多艺者、自负的人以及嘲讽堕落、朝生暮死生活的人，就像梅尼普以及类似于他的人。

The work of this paper is as follows: 1. Looking back the progressing history of the linear motor, introducing the features of the elevator driven by linear induction motor, radicating the topic of this paper "the digital frequency variable control of the elevator bi-side direct driven by linear induction motor". The research of this paper covers the conventional VVVF control, space vector based VVVF control, vector control and DTC.

本文主要开展了以下几个方面的工作： 1 回顾了直线电机发展历史，电机的驱动技术演变，特别是针对直线电机的驱动，简要介绍了直线感应电机驱动电梯的优点和不同结构类型，对传统的v／f控制，基于空间矢量法的v／f控制，矢量控制，和基于电压空间矢量的直接转矩控制进行了比较，确立了本课题的研究主题：直线感应电机双边直推式驱动电梯的全数字变频控制。

The article combines with the treatment of a superficial civil air defense work to introduce how the grouting method to improve the performance of the backfill soil.
