But as NPR's Joe Palca reports close is a relative term when it comes to astronomical distance.
但是据npr新闻的乔·帕尔卡报道,谈及天文距离时,“接近”是一个相对的说法。
This distance is known as the 'astronomical unit' or AU.
这个距离被称为“天文单位”或 AU。
An astronomical unit is the distance between Earth and our sun.
一个天文单位是地球与太阳之间的距离。
One astronomical unit is the distance between the Earth and the sun.
一个天文单位等于地球到太阳之间的距离。
Most planet-formation models predict a “planet desert” within one astronomical unit (or the average distance from the Earth to the sun) of a host star.
大多数行星形成模型预言在主恒星一个天文单位(或从地球到太阳的平均距离)以内会有一个“沙漠之星”。
The inner belt orbits at a distance of about 3 astronomical units from its star — or about the same position as the asteroid belt in our own solar system.
内侧行星带距离它的恒星为3个天文单位——或者相当于太阳系中的行星带与太阳的距离。
It sits fairly close to its star, at 14.5 astronomical units AU; one AU is the average distance between Earth and our Sun.
HR 8799e十分接近其围绕的恒星,它们之间的距离为14.5个天文单位AU;一个天文单位是指地球到太阳的平均距离。
One astronomical unit is the distance between the Earth and the sun, about 93 million miles (150 million km).
一个天文单位是地球与太阳的距离,大约9300万英里(1.5亿公里)。
One astronomical unit equals the distance from the earth to the sun.
一天文单位等于从地球到太阳的距离。
Know astronomical unit and light year are used for expressing the distance between celestial bodies.
知道天文单位和光年是用来丈量天体之间距离的单位。
The results show that GPS astronomical leveling is an effective method for height transfer across obstacle at a long distance with high precision.
研究结果表明:天文GPS水准方法是一种远距离、高精度跨障碍高程传递方法。
The distance from the sun to earth is one astronomical unit.
太阳到地球的距离即为一个天文单位。
The study and experimentation based on the above thought show that GPS astronomical leveling is an effective and high precision method for height transfer across obstacle with long distance.
根据以上设想进行的研究试验表明,“天文GPS水准”克服了单纯GPS水准无法连接不同高程系统的困难,对于远距离跨障碍高程传递是一种有效的高精度方法。
