角距离单位等于(待查表)毫弧。
A unit of angular distance equal to one thousandth of a milliradian.
测试距离单位为毫米，中和时间单位为秒。
没有人会那么说，一光年是距离单位不是时间单位。
No one would say that. A light year is a unit of distance not time.
为了度量天文距离，人们把光在一年中走过的距离当作一个距离单位。
To measure astronomic distances one takes as a unit that distance which light travels in a year.
这样在处理地理坐标下的数据的时候就出现问题，原因是水平距离单位为经纬度。
When working with data in geographic coordinates, this is a problem because the linear distance of a degree of latitude varies.
在美国，测量距离以英里作单位。
这个距离被称为“天文单位”或AU。
一个天文单位是地球与太阳之间的距离。
An astronomical unit is the distance between Earth and our sun.
一个天文单位等于地球到太阳之间的距离。
One astronomical unit is the distance between the Earth and the sun.

Dot is measured in millimeters (mm), and indicates the diagonal distance between same-colored phosphor dots on the screen.
较早的红外天文卫星(IRAS)的一次失败搜寻显示，5倍木星质量天体的距离必须大于10,000天文单位。
A failed search of older IRAS data suggests that an object of 5 MJ would need to have a distance greater than 10,000 AU.
说明它变得越来越陡峭，我要经过的距离更小，如果我改变海拔高度一个单位时。
That means it's getting steeper and steeper because I have to travel a shorter distance if I want my altitude to change by one.
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”。
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.
换句话说，它们是角度度量，以带小数部分的度数表示，不是直线距离(采用米、英尺或类似的单位)。
In other words, they are angular measures, in degrees with decimal fraction, not linear distances (in meters, feet, or similar units).
一般认为低照明介于15-30英尺烛光(照明单位，指每英尺距离内之照度)，高照明介于50 - 100英尺烛光之间。
Low light levels are considered 15-30 footcandles, and high light levels are considered in the 50-100 foot candle range.
定距尺度(interval)—在定距尺度中，任意两个相邻测量单位之间的距离(也称为间距)是相等的，但零点是任意的。
Interval - an interval scale is a scale of measurement in which the distance between any two adjacent units of measurement (also known as intervals) is the same, but the zero point is arbitrary.
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 is the distance between the Earth and the sun, about 93 million miles (150 million km).
它可能会在距离太阳3万个天文单位的地方被发现。
It could be found up to 30,000 astronomical units from the sun.
就是从透镜(或者主反射镜)到焦点的距离，通常单位是毫米(mm)。
This is the distance (usually in mm.) from the lens (or primary mirror) to the point where the telescope is in focus (focal point).
外侧那些沿着轨道运行的彗星距离恒星最远90个天文单位，最近35个天文单位；我们太阳系中的柯伊伯带与太阳的距离为30到50个天文单位。
The outer comet ring orbits from 35 to 90 astronomical units from the star; our solar system's analogous Kuiper Belt extends from about 30 to 50 astronomical units from the sun.
第二个行星带距离它的恒星为20个天文单位，这相当于太阳系中天王星的位置。
The second asteroid belt lies at about 20 astronomical units from the star, or a position comparable to Uranus in our solar system.
它每4.7天环绕恒星一周，其轨道为一个适度的椭圆，平均距离仅0.04个天文单位(为水星距太阳的十分之一)。
It orbits its star every 4.7 days, in a moderately elliptical orbit at a mean distance of only 0.04 AU (one tenth of Mercury's distance from the sun).
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。
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.
我帮你们查阅了一下-，各大行星到太阳的平均距离-，单位是百万千米。
So I look up the distance — - the mean distance to these various planets — and you see that here in millions of kilometers.
如果不使用级联阴影，整个阴影距离(仍然是50单位)内，阴影纹理均匀的覆盖。没有级联，硬阴影看起来像这样。
If no cascaded shadow maps were used, the entire shadow distance (still 50 units in our case) must be covered by the shadow texture uniformly. Hard shadows would look like this with no cascades.
这个程序非常基本——它计算在给定速度(单位为每小时英里数)和时间(单位为小时)情况下的旅行距离。
The program will be very elementary — it will calculate the distance travelled given a speed in miles-per-hour and a time in hours. Here is the code for the ppe (enter as ppe_distance.c).
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。
It sits fairly close to its star, at 14.5 astronomical units AU; one AU is the average distance between Earth and our Sun.
一个天文单位是地球到太阳之间的距离，大约9300万英里。
One AU is the distance between the Earth and the sun, about 93 million miles.
度量通常以间隔表示（10、20、30等等），代表度数字的单位，如价格、距离、年，或百分比。
Scales are often presented as intervals (10, 20, 30 etc. ) and will represent units of measurement, such as prices, distances, years, or percentages.
