The phrase "a simple relation of" is correct and usable in written English.
It can be used when describing a straightforward connection or association between two or more things.
Example: "The report provides a simple relation of the factors affecting climate change."
Alternatives: "a straightforward connection of" or "a basic link of".
The study also provides a simple relation for the number of repeating attenuation domes prior to the domination of higher order modes in terms of thel/dratio of the expansion chamber.
We derive a simple relation for estimating the critical depth of the crevice, Lc (which is defined as the depth at which the active passive transition just occurs within the crevice) as a function of the width of the crevice, w, electrolyte conductivity, κ, metal potential, Emet, and a polarization curve.
In principle there is a simple relation between the ratio of the radii of gyration and the hydrodynamic radii: g′ = gb.
Another drawback of the method is the lack of a simple relation between the drift times and the collision cross-sections of the analytes.
However, present results indicate that such a simple relation is an oversimplification of a far more complex relation that cannot be accurately used for modeling the catenary development.
In Leavitt's words, taken from her study of 1,777 variable stars recorded on Harvard's photographic plates, "A straight line can be readily drawn among each of the two series of points corresponding to maxima and minima, thus showing that there is a simple relation between the brightness of the [Cepheid] variables and their periods".
She explained her discovery: "A straight line can readily be drawn among each of the two series of points corresponding to maxima and minima, thus showing that there is a simple relation between the brightness of the variables and their periods".
When mutations are selectively neutral, or nearly so, the rate at which they are generated (the mutation rate) should have a simple relation with the rate of fixation (the substitution rate) [ 44].
And, given that this awareness is supposed to be a simple relation, there is no question of producing an analysis of the proposition which represents it as a conjunction of propositions each of which seem to express facts which do not depend on anything Jones can do.
A simple relation between adsorbability and "bulkyness" of the compounds, in relation to the dislodgement of water molecules from the surface occurring in the adsorption process is proposed and discussed.
