The phrase "at first approximation" is correct and usable in written English.
It is typically used in scientific or mathematical contexts to indicate an initial estimate or simplification of a more complex problem.
Example: "At first approximation, we can assume that the object is moving in a straight line without any external forces acting on it."
Alternatives: "initial estimate" or "first estimate".
At first approximation, offshore GCS-Geothermal coupling seems unlikely due to well costs and the additional engineering requirements.
From these results on equine SDFT it was demonstrated that tendon in axial quasi-static tension can be considered, at first approximation, as an incompressible material.
The CBS Outdoor promotion invites Londoners to send in their reasons for adoring the city, with the opportunity to see them published on the posters – an idea that at first approximation seems completely benign.
As the latter is not available for the CMIP5 models we use the daily minimum relative humidity, as done in other studies11, which at first approximation coincides with the maximum temperature at the diurnal cycle.
Given how few and far between the scansoriopterygids are as fossils, this implies that they never really got going as a group – certainly they are much more restricted in both time and space than their near relatives, so at first approximation the bat-bird combination of Yi qi did not lead to a major new radiation of dinosaurs.
It satisfies, at least at first approximation, the extensional constraints: there are many actions with respect to which a typical agent satisfies the relevant conditional, and also many actions with respect to which she does not, and these roughly correspond to her abilities.
This strategy can be completely automated and thus provides a convenient shortcut to gene family classification within the fast growing body of fully sequenced species, at least at a first approximation.
However, the finding that expression of active mutant of Gαo promoted Necdin-mediated cellular activities suggests, at least at a first approximation, that Gαo can modulate Necdin functions.
So! Like, yeah," she means: "The teacher, becoming heated"—that's why she "got, like," rather than "said, like"—"announced, in effect, that many of us (I suppose, at a first approximation, all)will, at some point in, as it were, the near future, have to take what actually amounts to, when all is said and done, a secondary makeup test.
