The phrase 'theory basis' is correct and usable in written English.
It is usually used when referring to the foundational concepts of a particular theory or idea. For example, "We need to review the theory basis of our current project before moving forward with implementation."
Our results provide a reliable theory basis for exploring biological resource management in a polluted environment.
All these could provide the theory basis for the realization of embedded FBG sensor's sensitivity enhancement.
It provides the theory basis for analyzing the suction within the jet tube.
And the research builds the theory basis for dimensional design, trajectory planning and control of this type of manipulator.
The improved method for rank correlation analysis is suitable for computer analysis, and provides theory basis for subsequent implementation of the comprehensive testing and evaluation system.
This work was devoted to provide the theory basis for the design and development of novel and advanced O3 sensors based on modified TiO2/WSe2 nanocomposites.
Unfortunately, only some combinations of QM theory levels, basis sets and population analyses are available.
These results also confirm that our selection of QM theory level, basis set and charge calculation schemes is appropriate.
Electronic structures as well as molecular interaction have been investigated using Hartree Fock theory, 3-21G baset set.
Two or more EEM parameter sets are available in literature for four combinations of theory level, basis set and population analysis (see Table 1).
We calculated QM atomic charges for all the combinations of QM theory level, basis set and population analysis for which we have EEM parameters (see Table 1).
