Construction on the Temple of Abu Simbel lasted for about 20 years, from 1244 B.C., until

修建阿布辛贝寺庙大约用了20年的时间，从公元前1244年到公元前1224年。

This global network of 3 million computers averages about 14 TeraFLOPS, or 14 trillion floating point operations per second, and has garnered over 500,000 years of processing time in the past year and a half.

大约 300 万台计算机，计算效率约为平均每秒运行 14 TeraFLOPS 或 14 兆浮点操作每秒，在过去的一年半的时间里项目共计调用了大概 500，000 年的 CPU 处理时间。

Minutes waiting and getting pass US border, including computer was down and rebooted twice on one of us.

从我的住处到美加边境大约40分钟的车程。20分钟时间过美国海关，包括计算机2次死机和再启动的时间。

The Jet Balloons will be used for the first time in Holland. They are special balloons, equipped with a valve. They should be inflated five minutes before the players enter the pitch, so that the entire stadium will be an ocean of red-white colours. The moment the referee leads players unto the pitch, the balloons should be released. They go straight up due to the valve and produce a great sound. If over 30, 000 spectators do so at the same time, the effect could be very special indeed!

这些气球的使用，在荷兰应该是第一次，它们都是一些特殊的气球，它们将在球员们进场前在体育场上空飘荡大约5分钟，所以，体育场在这段时间将会是一个红、白色的海洋，而等到这些球员都进场后，这些气球就会被释放，同一时间，它们将伴随着巨大的响声向上飘起，它们的数目可能超过3万多个，到时候景象会是非常壮观的！

The median door 1–to-departure time was 46 minutes (25th and 75th percentiles, 32 and 62 minutes); approximately two thirds of this delay was attributable to the wait for transport arrival and departure.

平均的通道1到离开时间为45分钟（25th和75th百分点，32和62分钟），大约2/3的时间耽搁归因于等待运输工具的到达和出发。

At the present time, their size has arrived at nanometer scale, and it approximately takes several picoseconds, or even shorter time, for free carriers to transport during such small distances. Therefore, research of carrier dynamics in silicon on shorter and shorter time scale is urgently developed. Processes on such short time scale are difficultly measured by traditional electronic method, so ultrafast spectroscopy method is the only choice of carrying out such experiments. Additionally, application of photoelectric detectors is severely influenced by laser.

近年来，硅半导体器件尺寸不断变小，目前已经缩小到了纳米尺度，载流子在这个尺度内的输运时间大约在ps量级，这促使人们需要对越来越短的时间尺度内硅的载流子动力学进行研究，传统的电子学方法很难对这么短时间尺度内发生的现象进行测量，超快光谱探测几乎成了进行这类研究的唯一测试手段。

It took Cockcroft and Walton five years to build a machine that worked. Finally, in April 1932, they had a machine that produced a steady stream of hydrogen nuclei with an energy of about half a million volts. They were carefully measuring the quality of the stream, in no hurry to begin doing nuclear experiments. On the morning of April 13, Rutherford came into their room, saw what they were doing, and lost his temper. He told them to stop wasting their time and do some science. The next day, Cockcroft was occupied with other business. Walton was alone in the laboratory, ready to do the first experiment, using his hydrogen nuclei to bombard a target made of the light metal lithium. The result was spectacular. The lithium nuclei were split in two and fell apart into pairs of helium nuclei.

用了五年时间，考克饶夫和华尔顿建造出了第一台能运行的加速器，最终，在1932年，他们制造出了能够提供稳定氢粒子流的加速器，粒子能量大约为50万伏特，他们并没有急着做核试验，而是精心测量了粒子流的性质，4月13日清晨，卢瑟福来到他们的房间，看到他们还在测量，大发雷霆，告诉他们停止浪费时间，开始科学研究，第二天，考克饶夫就被安排了其他事情，只剩华尔顿一个人在实验室里，准备做第一次实验，用他的氢粒子流轰击用轻质金属锂作的标靶，结果极为壮观，锂原子被分裂成两半形成一对氦原子，氦原子释放出的能量比氢原子注入的多达三十倍！

The eclipse began at about 5.30 am gmt and was seen first in the eastern city of Gauhati in India.

日食大约于格林威治时间时间上午5点30分开始，首次出现于印度东部城市高哈蒂。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
