例句與造句

1. The inclination of the Earth's orbit has a 100, 000-year cycle relative to the invariable plane.
2. The invariable plane, the plane that represents the angular momentum of the Solar System, is approximately the orbital plane of Jupiter.
3. See Poinsot's construction, which is summarized by the delightful phrase " the polhode rolls without slipping on the herpolhode lying in the invariable plane ".
4. It has been proposed that a disk of dust and other debris exists in the invariable plane, and this affects the Earth's climate through several possible means.
5. These two constraints operate in different reference frames; the ellipsoidal constraint holds in the ( rotating ) principal axis frame, whereas the invariable plane constant operates in absolute space.

8. For other planets in the Solar System, north is defined as being in the same celestial hemisphere relative to the invariable plane of the solar system as Earth's North pole.
9. :See Poles of astronomical bodies, which has " The north pole is that pole of rotation that lies on the north side of the invariable plane of the solar system ".
10. Laplace's name is sometimes applied to the invariable plane, which is the plane perpendicular to a system's mean angular momentum vector, but the two should not be confused.
11. The invariable plane is simply derived from the sum of angular momenta, and is " invariable " over the entire system, while the Laplace plane may be different for different orbiting objects within a system.
12. If all Solar System bodies were point masses, or were rigid bodies having spherically symmetric mass distributions, then an invariable plane defined on orbits alone would be truly invariable and would constitute an inertial frame of reference.
13. Laplace called the invariable plane the " plane of maximum areas ", where the area is the product of the radius and its differential time change dR / dt, that is, its velocity, multiplied by the mass.
14. The trajectory of the angular velocity around the angular momentum in the invariable plane is a circle in the case of a symmetric top, but in the general case wiggles inside an annulus, while still being concave towards the angular momentum.
15. One might reasonably argue that it ought to be measured from the invariable plane ( closer to Jupiter's orbital plane ), but the difference is less than 2?.  talk ) 05 : 31, 13 October 2013 ( UTC)
16. :There are some objects that are inclined well off the invariable plane such as 4 Vesta at 35?and 1566 Icarus at 23? but as you point out, the majority of the mass of the solar sytem is orbiting in one plane.
