angular diameter distance造句

例句与造句

1. For extragalactic lenses, these must be angular diameter distances.
2. The distance measured by a standard ruler is what is known as the angular diameter distance.
3. Occasionally, the symbols \ chi or r are used to denote both the comoving and the angular diameter distance.
4. Angular diameter distances to the lenses and background sources are important for converting the lensing observables to physically meaningful quantities.
5. Peebles ( 1993 ) calls the transverse comoving distance the " angular size distance ", which is not to be mistaken for the angular diameter distance.
6. It's difficult to find angular diameter distance in a sentence. 用angular diameter distance造句挺难的
7. This is related to the angular diameter distance, which is the distance an object is calculated to be at from \ theta and x, assuming the Universe is Euclidean.
8. An object of size x at redshift z that appears to have angular size \ delta \ theta has the angular diameter distance of d _ A ( z ) = x / \ delta \ theta.
9. In non-Euclidean space, such as our expanding universe, the angular diameter distance is only one of several definitions of distance, so that there can be different " distances " to the same object.
10. This signal in the power spectrum can be used as a standard ruler to map out the evolution of the Hubble parameter, H ( z ), and the angular diameter distance d _ A ( z ) with redshift . This in turn constrains the properties of dark energy and other cosmological parameters.
11. Note that beyond a certain redshift, the angular diameter distance gets smaller with increasing redshift . In other words, an object " behind " another of the same size, beyond a certain redshift ( roughly z = 1.5 ), appears larger on the sky, and would therefore have a " smaller " " angular diameter distance ".
