engineering approximation造句

Most relational databases use the SQL data definition and query language; these systems implement what can be regarded as an engineering approximation to the relational model.
However, much of their work is made possible by engineering approximations to the more exact physics-and somebody had to invent those approximations in the first place.
There are several known solutions to the slug test problem; a common engineering approximation is the Hvorslev method, which approximates the more rigorous solution to transient aquifer flow with a simple decaying exponential function.
That said, systems " can " be synchronized ( at an engineering approximation ), using technologies like GPS . The GPS satellites must account for the effects of gravitation and other relativistic factors in their circuitry.
That there is some " bleeding " of luminance and color information between the luma and chroma components in video, the error being greatest for highly saturated colors and noticeable in between the magenta and green bars of a color bars test pattern ( that has chroma subsampling applied ), should not be attributed to this engineering approximation being used.
It's difficult to find engineering approximation in a sentence. 用engineering approximation造句挺难的

Failure analysis is a tough problem; letting the fan run seems like an " engineering approximation " to the optimal thermal profile, given the constraint that it's hard to really estimate the likely cause of failure, and even harder to actually control the temperature in an ideal way . talk ) 21 : 23, 24 August 2009 ( UTC)
