In 1976, the International Astronomical Union revised the definition of the AU for greater precision, defining it as that length for which the Gaussian gravitational constant takes the value 0.01720209895 when the units of measurement are the astronomical units of length, mass and time.

但实际上地球绕日的轨道不是一个圆形，而是一个椭圆形：最初天文单位的定义就是上述椭圆的半长轴的长度。1976年，国际天文学联会把一天文单位定义为一颗质量可忽略、公转轨道不受干扰而且公转周期为365.2568983日的粒子与一个质量相等约一个太阳的物体的距离。

According to introduction, they make use of Europe south the astronomical observatory establish in 3.6 meters caliber astronomical telescope of the Chile a set of the mountain lodge of 2400 meters saddle type of an elevation, confirm Be located on south the fixed star"Gliese 581" inside the along while ball scales horoscope see toward the speed because it surroundings can't see fixed star of gravitation function but"perturbation" for appear, subsequently reckon this a red and short star neighborhood of"new the Earth" round a mother fixed star of revolution around sun period and quality.

根据行星的介绍，他们利用欧洲南方使用建立天文台3.6米口径的智利一集的山2400米的海拔马鞍型，提出确认将于南部的恒星"格里斯581"所在的内沿，同时对球尺度占星速度见的天文望远镜因为它周围看不到固定的引力作用，但"摄动出现，随后估计这是一个红色的和短期的"新地球"轮明星邻居母亲围绕太阳固定期限和质量革命之星"的明星。

On the special structure of the Lower Latitude Meridian Circle and the practice of determining astronomical refraction in Yunnan observatory,a new method for improving the correction accuracy of the atmo- spheric refraction delay is proposed:the determined data of the astronomical atmospheric refraction values with different azimuths are utilized to find the refractivity and the param- eters of mapping functions for modeling the atmospheric refraction delay correction,which changes with the observing stations and azimuths.

根据云南天文台低纬子午环的特殊结构，和测定大气折射的实践，提出了提高折射延迟改正精度的新方法，即：利用各观测站不同方位从天顶附近直到低地平高度角的天文大气折射实测数据，求解得到折射率差和映射函数的参数，从而建立随测站和随方位而异的大气折射延迟改正模型。

The inner asteroid belt looks identical to ours in terms of material, and it orbits at 3 astronomical units from Epsilon Eridani — the same distance between the sun and the rocky asteroid belt between Mars and Jupiter. An astronomical unit equals the average Earth-sun distance of 93 million miles, or about 150 million km.

内围小行星带中的物质看起来跟我们太阳系的小行星带一模一样，在3天文单位的距离上环绕着恒星& E 波江&——这个距离跟火星和木星之间的小行星带到太阳的距离也一样。1天文单位等于地球跟太阳之间的平均距离，相当于9，300万英里，或者15，000万公里。

Google Sky add-on to Google Earth is developed with partnership from some of the world's leading observatories such as Sloan Digital Sky Survey, Digital Sky Survey Consortium which obtained photographic data from Oschin Schmidt Telescope on Palomar Mountain and the UK Schmidt Telescope and NASA/Space Telescope Institute, the science operations center for Hubble space telescope, the main source for Google Earth Sky add-on service where public astronomical images as well as color astronomical images of all of the archived data from Hubble's Advanced Camera for Surveys will be added and shown, together with newly released Hubble pictures will be added to the Google Sky program as soon as they are issued.

Google的天空添加就到Google Earth是发达国家与伙伴关系，从世界上一些领先的观测站，如斯隆数字天空调查，数字天空调查的财团获得摄影数据，从oschin施密特望远镜对帕洛马山区和英国施密特望远镜和美国航天局/太空望远镜研究所，科学营运中心，为哈勃太空望远镜，主要来源为Google地球天空添加对公共服务的天文图像，以及彩色的天文图像，所有的存档数据，从哈勃望远镜的高级照相机拍摄的调查加入和显示，加上新公布的哈勃照片将被加入到Google的天空计划，尽快，因为他们发出的。

If you want to modify the clock, pressure Settings button to display window, input zero - 23:59 at the score (e.g., at about 3:30 p.m., second automatic reset input 1530, set the clock in 24 hours, and then press enter) system clock.

若要修改时钟值，压设置键显示窗口在闪烁，输入0-23点59分的时分值（如下午3点30分输入1530，秒自动清零，设置时钟时按24小时制输入），然后压时钟键即可。

The STK730-080 is a zero delay buffer that distributes a differential clock input pair to ten differential pairs of clock outputs (Y[0:9], Y[0:9]) and one differential pair feedback clock outputs .

该STK730 - 080是一种零延迟缓冲器，差分时钟分配一个输入对，以10的时钟输出（是[0时09]， [0点09]）和一个差分对的差分对时钟输出反馈（FBOUT，FBOUT）。

Finally, there is a cuckoo clock: according to written records, approximately 164 years with a pair of brothers named ESH invented the first block of FireWire world resting clock, which is the predecessor of a cuckoo clock, and later in 1750, settle an old francs.

最后是咕咕钟：根据记载，大约在1640年的时候，有一对名叫库兹的兄弟发明了第一座世界上最早问世的木架钟，这是咕咕钟的前身，后来在1750年时，一位法朗安顿。

There are a lot of graphics on Cuckoo Clock - classicalclock, futuristic clock, office clock and Big Ben.

Parallaxis Cuckoo Clock 这架杜鹃时钟在你的计算机的桌面，玩抑扬顿挫地说正点，半点钟和一刻钟。

It was just a normal day of school

那只是上学的普通一天

Which is a very good reference in this issue.

这是一个在这个问题上很好的参考。
