The phrase "a theoretical value" is correct and usable in written English.
It can be used in contexts where you are discussing a value that is based on theory rather than empirical evidence or practical application.
Example: "In our calculations, we used a theoretical value for the speed of light to determine the outcomes of the experiment."
Alternatives: "an abstract value" or "a conceptual value".
However, it only expires when the share price exceeds 65p for 20 days in any 30 day period and has a theoretical value of up to £2.3bn.
This work provides a theoretical value range for optimal allocation of heat transfer areas of the CRHR.
The celebration of what the tweeting Tory MP Aidan Burley called "multicultural crap" was not only a theoretical value but a living example of possibility and achievement and love in the family of Jessica Ennis, and the soon to be expanding family of Mo Farah, among many others.
Additionally, the heat transfer coefficient and the overall heat transfer coefficient of the falling-film-type heat exchanger were logically calculated, and then a theoretical value and an experimental value were compared and evaluated.
The ESN has a theoretical value in that it is useful for judging what makes a good source enumerator in the threshold region and can be employed as a performance benchmark of various source enumerators.
Protective layers deposited by atomic layer deposition (ALD) can be much thinner than those prepared by physical vapor deposition; the YSZ/GDC thickness ratio for a stable operation approached close to a theoretical value when the ALD was used.
The value of X was allowed to vary randomly within the limits describing different data ranges, and a was set to a fixed theoretical value.
The NBO derived charge transfer can be compared to the experimental δi values, and it is observed that theoretical values are a little larger than experimental, for example, on formation of H3N⋅⋅⋅BrCl δi is roughly 0.06 of an electronic charge, with a corresponding theoretical value of 0.10.
This research will have a significant theoretical value and engineering practical significance.
(Those options had a combined theoretical value at issuance of $16.5 million, but the compensation figures in this survey count options only when they are cashed in).
Therefore, the optimization problem incorporating both the effects of biological control and chemical control has an important theoretical value as well as practical significance.
