The phrase "average separation" is correct and usable in written English.
It can be used in contexts involving statistics, measurements, or comparisons where you want to describe the typical distance or difference between two or more entities.
Example: "The average separation between the two points in the study was found to be 5 meters."
Alternatives: "mean distance" or "typical gap".
Experimentally, a magnetic separator was used to separate the magnetic ferrites from steel flyash with an average separation fraction of 74%.
The average separation is 850 meters, so they are widely spaced.
Moreover, the average separation force per CNT differs among samples.
They are free to vibrate back and forth about an average separation distance known as the average bond length.
The distances are given in astronomical units (1 au is the average separation between Earth and the Sun).
Sirius and its companion revolve together in orbits of considerable eccentricity and with average separation of the stars of about 20 times Earth's distance from the Sun.
The higher density regions became the seeds of galaxies and the average separation of those galaxies thus reveals the wavelength of the oscillations in the primordial fluid.
Because the spacecraft fly incredibly close together — at an average separation of just four and a half miles — they are able to observe phenomena no one has seen before.
The potential detection distance through cross-relaxation should be at least ~8 nm, as estimated by the average separation of neighbouring NV− centres in our diamond sample, between which cross-relaxation is clearly detected in our measurements39 (Supplementary Note 3).
When the longest of the two walls (13.7 m) was normal to the wind, the average separation bubble was 1.04 m tall and 4.42 m long.
It can be seen that at these time scales and for the Jan-4 data set the auto-correlation is small even for small values of the Lag (the minimal lag or average separation between adjacent samples for RIPE is about 40 seconds, and for Surveyor it is about 1 second) the auto correlation has a very small value.
