Scope

This part of GB/T 16656 specifies the integrated resource structure of mathematical expressions. This standard applies to: Using numerical values to identify or describe products, characteristics, states, activities and characteristics; Using mathematical spaces as identification patterns for products, characteristics, states, activities, sets of characteristics or spaces; Using mathematical functions to describe products, characteristics, states and characteristics Characteristic changes in activities; identification patterns or parameterization of point collections in the product body; objects of type XYZ have a simple shape for easy mapping. More complex objects can be divided into parts such that each part maps to a unit cube or some other simple mathematical space. The identification mode or parameterization of the feature set in the product body; the identification mode or parameterization of the state in the state space or activity; the identification mode or parameterization of the feature set of the product itself or the state set in the state space or activity; in the physical quantity space , the identity of the value or the description of the value related to the unit of measurement or the unit of measurement, the coordinate system and the coding method; use a mathematical function to describe the distribution of characteristics; use a mathematical function to describe the relationship between two parameters; use a mathematical function to describe the relationship between two parameters relationship between scalars. This section does not apply to: Definition of domains and distribution ranges of characteristics; Definition of mathematical functions.
