The phrase "as a good approximation" is correct and usable in written English.
It can be used when discussing estimates or approximations in various contexts, such as mathematics, science, or general discussions.
Example: "The value of pi can be represented as a good approximation by using 3.14 in many calculations."
Alternatives: "as a reasonable estimate" or "as a close approximation".
It was his idea to use as a good approximation for the ideal blackbody an oven with a small hole.
Classical diffusion is known as a good approximation of transport only in scattering media.
is a random rotation matrix into all solid angles for each collision event, which serves as a good approximation of the real elastic cross-section11.
The idealized Weaire-Phelan metal foam geometry serves as a good approximation to a real metal foam geometry.
The present formulas are able to serve as a good approximation of the elastic properties for SWNTs.
The solid body with the new turbulence model (SST k ω) was considered as a good approximation to the real life.
Aside from the polynomial basis, it is possible to use other types of basis function in PTM, as long as they provide a good approximation of the light-reflectance interaction.
Guolo [ 26] suggested the use of skew-normal family of distributions as long as this distribution is a good approximation of the distribution of the unobserved exposures in the case-control sampling.
The last hypothesis simply states that the system is at equilibrium, a good approximation as long as the rate constants are large compared to the rate of change of the rate constants.
Comparison with simulations show that the analytical results are not only asymptotically exact (as L→∞), but a good approximation also when L is relatively small.
The dependence of the equilibrium on pressure is intuitively understandable as follows: to a good approximation, the volume that a gas occupies at a given pressure and temperature depends directly on the number of gas molecules.
