precession 的定义
- the act or fact of preceding; precedence.
- Mechanics. the motion of the rotation axis of a rigid body, as a spinning top, when a disturbing torque is applied while the body is rotating such that the rotation axis describes a cone, with the vertical through the vertex of the body as axis of the cone, and the motion of the rotating body is perpendicular to the direction of the torque.
- Astronomy. the slow, conical motion of the earth's axis of rotation, caused by the gravitational attraction of the sun and moon, and, to a smaller extent, of the planets, on the equatorial bulge of the earth.precession of the equinoxes.

- The new study also found evidence of phase precession outside of spatial tasks, lending some weight to the idea it may be a more general process in learning throughout the brain.
- The researchers say more studies are needed to flesh out the role of phase precession in the brain, and how or if it contributes to learning is still uncertain.
- Notably, the rate of that precession diverged slightly from the standard model expectation, physicists report April 7 in a virtual seminar, and in a paper published in Physical Review Letters.
- A radiofrequency pulse not only knocks protons down, but synchronizes their spins with each other, matching their precession frequencies into a coordinated group choreography.
- After the pulse, the precession frequencies gradually become unsynchronized again as the protons return to their upright orientation, spinning off at different rates like dancers embarking on their solos.
- This is due to what is known as "precession;" a slow movement of the axis upon which the earth rotates.
- Does the precession of the equinoxes have any effect upon the seasons or upon the climate of different parts of the earth?
- Will the precession ever bring back the right ascensions and declinations to be again what they now are?
- This slow movement forward of the goal-post is called precession—the precession of the equinoxes.
- Instruct the computer to discontinue precession operations that have been initiated.
