| 1. | Tilting the polar axis adds a level of complexity to the mount.
|
| 2. | A polar symmetry direction of a crystal is called a polar axis.
|
| 3. | A Polar Axis telescope was built at Jodrell Bank in 1962.
|
| 4. | The basic SOON telescope is a evacuated refractor mounted on a polar axis.
|
| 5. | Groups containing a polar axis are called " pyroelectric crystals.
|
| 6. | It has 10 faces on the polar axis with 10 faces following the equator.
|
| 7. | A polar axis can occur only in non-centrosymmetric structures.
|
| 8. | The polar axis is inclined by about 60?to the line of sight from the Earth.
|
| 9. | This polyhedron can be constructed by taking a pentagonal bipyramid and truncating the polar axis vertices.
|
| 10. | Coordinates were specified by the distance from the pole and the angle from the " polar axis ".
