The phrase "a standard relation" is correct and usable in written English.
It can be used in contexts discussing relationships, connections, or comparisons that are typical or widely accepted in a particular field or subject.
Example: "In mathematics, a standard relation between two variables is often represented by a linear equation."
Alternatives: "a typical relationship" or "a conventional connection."
"I think L.A. really is a shining star and a standard in relation to how a big city can actually collaborate," said J. Kevin Cameron, an expert on school shootings and executive director of the Canadian Center for Threat Assessment and Trauma Response, who has consulted with the program.
Furthermore, "roughly equal" is a relation that can be defined only in virtue of three items, and as such, appears to be something distinct from a standard comparative relation.
The crack size is then computed using the standard relation between stiffness and crack size.
We build on recent results in psychology to argue that comparative optimism deeply affects this standard relation.
The signals were normalized to the fraction of unfolded species using the standard relation F unf = (I − I N /(I U − I N), where N and U stand for the fluorescence intensity of the native and fully unfolded species, respectively.
The DQ model (2) can be further refined by exploiting the H.264/AVC standard relation, where QStep doubles in value each six increments of QP [14] with QStep being the quantization step size and QP the quantization index.
The technique is based on the multi-step prediction error and on knowledge of the system initial condition and it takes an advantage of the well-known standard relations from the area of state estimation techniques and least square method.
There is some debate as to whether "roughly equal" is in fact a fourth comparative relation to be considered in addition to the three standard relations, "better than," "worse than," and "equally good".
Consequently, many standard relations and factors used in one region may not be suited for others.
