The phrase "a suitable approximation for" is correct and usable in written English.
You can use it when discussing a method, model, or calculation that closely represents or estimates a particular value or concept.
Example: "In this study, we found that the linear model serves as a suitable approximation for predicting the outcomes of the experiment."
Alternatives: "an appropriate estimate for" or "a fitting representation of".
This scaling is a suitable approximation for the present study.
Multilinear Time Invariant systems (MTI systems) can be a suitable approximation for such systems.
The displacement interpolation is enhanced by linking the transverse displacement to the nodal rotations and a suitable approximation for stress resultants is selected, ruled by the minimum number of parameters.
This transition defines a second ignition delay time, τDDT, which is a suitable approximation for the chemical ignition delay time, if the change of the thermodynamic conditions of the unburned test gas due to deflagration is taken into account.
Another important aspect to note is that the union bound is not a good approximation for channels subject to severe fading conditions, but it becomes a suitable approximation for better channel conditions.
The impulse response can be computed to any desired degree of accuracy by choosing a suitable approximation for δ, and once it is known, it characterizes the system completely.
For this model to produce a suitable approximation of reality, the supply-constrained sectors must correspond to tradable goods.
First, a wide variety of different analytic formulae were tested to search for a suitable approximation formula for the radii ((R_{L1}), (R_{bk}), (R_{y}), (R_{z}) and (R_{eq})) as a function of q.
□ The following lemma asserts, in particular, that the approximation class B s from (4.2) is a suitable approximation class for the inexact problem (7.1).
A suitable approximation to the matched filter for the ordinary pulse radar, however, is one whose bandwidth in hertz is the reciprocal of the pulse width in seconds.
