The phrase "a distinct plane" is correct and usable in written English.
It can be used to describe a specific, clearly defined level or surface in various contexts, such as geometry, aviation, or metaphorical discussions.
Example: "In the study of geometry, we often refer to a distinct plane when discussing two-dimensional shapes."
Alternatives: "a separate level" or "a clear surface".
However, some ambiguities arose when determining a distinct fault plane because the aftershocks seemed to have occurred not only on the fault but also off of the fault.
In the context of our work, a composition of (sub systems can be represented by a superposition of distinct planes that interact, like in Fig. 3.
Based on the hypocentral distribution of earthquakes, the slab geometry shows a gently dipping trend and ridge-shaped features, with the intra-slab seismicity forming a distinct double-plane seismic zone.
The operative measures which are required in the treatment of badly united fractures are similar except that the fragments have to be cut through in two distinct planes in fracture of a single bone and in four planes in fracture of two bones such as the radius and ulna or tibia and fibula, in order that the axes of the fragments can be rendered continuous.
Here we have an example of a political question about which a person can make up his mind on two distinct planes-the foreign and the domestic.
That Britten conceived the piece acoustically to operate on three distinct planes of sound makes the Albert Hall enough of a surrogate cathedral to fulfil his wishes.
A sequence of strata, therefore, may appear as alternations of coarse and fine particles, as a series of colour changes resulting from differences in mineral composition, or merely as layers of similar aspect separated by distinct planes of parting.
The DCF was calculated at the interatomic separation r between pairs of atoms and can be resolved into distinct planes within the structure and along the polar ⟨11̅0⟩p and the two nonpolar ⟨001⟩p and ⟨110⟩p directions.
Significantly, in the medial plane a distinct focal point of actin is seen at the cell apex (Figure 3A).
(For instance, the group of rotations in the plane has a distinct element for every angle in the range 0 360 degrees; the composition of two rotations is of course the single rotation through the sum of their angles).
