例句與造句

1. The same method of measuring parallax angles and applying the skinny triangle can be used to measure the distances to stars; at least the nearer ones.
2. The base angles are very nearly right angles and would need to be measured with much greater precision than the parallax angle in order to get the same accuracy.
3. The difference in angle between the two measurements is twice the parallax angle, which is formed by lines from the Sun and Earth to the star at the distant vertex.
4. The parallax angle is given in the adjacent box, and the angular diameter is known from lunar occultation measurements ( 41.3 ?0.1 solar radii at this distance.
5. The base of the triangle is formed by the distance between two measuring stations and the angle " ? " is the parallax angle formed by the object as seen by the two stations.
6. It's difficult to find parallax angle in a sentence. 用parallax angle造句挺難的
7. Even so, Hipparcos is only able to measure parallax angles for stars up to about 1, 600 light-years away, a little more than one percent of the diameter of the Milky Way Galaxy.
8. The distance to a star with a parallax angle of only one arcsecond measured on a baseline of one AU is a unit known as the parsec ( pc ) in astronomy and is equal to about 3.26 light years.
9. In 2013, a Silicon valley Company LEIA Inc started manufacturing holographic displays well suited for mobile devices ( watches, smartphones or tablets ) using a multi-directional backlight and allowing a wide full-parallax angle view to see 3D content without the need of glasses.
10. The European Space Agency's Gaia mission, launched in December 2013, will be able to measure parallax angles to an accuracy of 10 microarcseconds, thus mapping nearby stars ( and potentially planets ) up to a distance of tens of thousands of light-years from Earth.
11. The European Space Agency's Gaia mission, launched 19 December 2013, is expected to measure parallax angles to an accuracy of 10 microarcseconds for moderately bright stars, thus mapping nearby stars ( and potentially planets ) up to a distance of tens of thousands of light-years from Earth.
12. The use of the parsec as a unit of distance follows naturally from Bessel's method, because the distance in parsecs can be computed simply as the reciprocal of the parallax angle in arcseconds ( i . e . if the parallax angle is 1 arcsecond, the object is 1 pc from the Sun; if the parallax angle is 0.5 arcseconds, the object is 2 pc away; etc . ).
13. The use of the parsec as a unit of distance follows naturally from Bessel's method, because the distance in parsecs can be computed simply as the reciprocal of the parallax angle in arcseconds ( i . e . if the parallax angle is 1 arcsecond, the object is 1 pc from the Sun; if the parallax angle is 0.5 arcseconds, the object is 2 pc away; etc . ).
14.
