The phrase "strictly valid" is indeed correct and usable in written English.
It is used to emphasize the extent to which something is true or valid, implying that it is true without question. For example, "The results of the experiment are strictly valid."
Under those conditions, the assumption of fast chemistry, which has been the cornerstone of many turbulent combustion models, is not strictly valid anymore and the validity and applicability of classical combustion models such as flamelet models might be limited.
Special relativity, as the 1905 theory became known, is only strictly valid in flat space without gravity, Dr. Strominger said.
However this is strictly valid for semi-infinite samples only.
This method is only strictly valid for simple reactions without adsorbed intermediates.
Theorem 3.1 The inclusion c 0 λ ( B ˜ ) ⊂ c λ ( B ˜ ) is strictly valid.
Although the method is strictly valid for high frequencies, it gives good quantitative results down to resonant frequency range.
The above model does not account for phonon-assisted processes and therefore is strictly only valid for NPs emitting PL at the threshold energy of 1.63 eV.
From the theoretical results it can be concluded that reciprocity with respect to the point-cross mobility elements is strictly, only valid in the hypothetical case of point excitation.
The conclusions drawn from our research are strictly only valid for patients from the former Yugoslavia.
These simplifying assumptions are strictly not valid at higher levels of insoluble solids as discussed by others [ 27- 29].
The low data-to-parameter ratio invalidates the AIC and non-nested LLR tests, as it strongly violates the approximations needed to justify the tests (the AIC and LLR are strictly only valid in the asymptotic limit of infinite data) [ 94, 105].
