The phrase "a more rigorous description" is correct and usable in written English.
You can use it when you want to emphasize the need for a detailed and precise explanation or characterization of something.
Example: "In order to fully understand the concept, we need a more rigorous description of the underlying principles."
Alternatives: "a more detailed explanation" or "a more thorough account".
In contrast to force fields, QM can achieve a physically more rigorous description of chemical systems.
Such plot together with the note on which time point was used to measure the activity in the remaining experiments would have provided a clearer more rigorous description of the data.
Recent works have shown that some types of materials and therefore structures demand a more rigorous behavior description and that it seems possible to address the problem by means of the theory of fractional derivatives, leading to a model in terms of general damping parameters.
To overcome this limitation, we reconstructed a new version of the Saccharomyces cerevisiae genome-scale model, iIN800 that includes a more rigorous and detailed description of lipid metabolism.
A more rigorous and classical theoretical framework for the description of the non-WSSUS channels was introduced by Matz [2], where instead of the WSSUS scattering function, the local scattering function (LSF), in consonance with the concept of time-dependent spectrum for nonstationary analysis, was defined.
We have formulated an analytic expression for the electroreflectance (ER) spectrum associated with the valence donor transition in terms of the nonlocal description of optical response, a more rigorous approach than the long-wavelength approximation.
Otherwise, for testing, one would require a more mechanistic description, inclusion of other key organs and regulatory mechanisms, and a more rigorous mathematical analyses.
A more rigorous discussion of jittered sampling.
A more rigorous test may prove more practically useful.
