[′nōd·əl ‚līn]
(astronomy)
The line passing through the ascending and descending nodes of the orbit of a celestial body.

A line or curve in a two-dimensional standing-wave system, such as a vibrating diaphragm, where some specified characteristic of the wave, such as velocity of pressure, does not oscillate.
A line which remains fixed during some deformation or rotation of a body or coordinate system.

Why must the side of measure be divided into a nodal line? This is the inheritance from immediate measure (specific quantity) and rule.
Notice too that if an inferior conjunction falls very close to the nodal line, then neither the alignment 8 years earlier nor the one 8 years later will land in the transit zone, so there would be only a single transit in that century.
These clearly delineated, stationary regions are called nodes or nodal lines. The resulting patterns depend on the geometric shape of the vibrating object--and on such characteristics as its stiffness and density distribution.

The 0.03-0.15 Hz was selected for waveform inversions because P-wave polarities are in good agreement with nodal lines in the same direction.
They are usually identified by two indices (m,n), where m counts the number of nodal lines crossing the crown, and n the number of circumferential nodal lines.
