The pair of templates {{EquationRef}} and {{EquationNote}} is used for labeling equations in text.

For example, 模板:Markup2 Here, the identifier "Eq. 1" is a label which can be later referred to with a call to {{EquationNote}}. That is, {{EquationNote|Eq. 1}} produces a link Eq. 1 to this equation.

Similarly, 模板:Markup2 which can be referred to by {{EquationNote|2}} or even {{EquationNote|2|Equation 2}} (i.e., Equation 2).

This template can be used together with {{NumBlk}} to produce nicely formatted numbered equations. For instance:

which may then be referred to by {{EquationNote|3}} or even {{EquationNote|3|Eq. 3}} (i.e., Eq. 3).

which may be referred to by {{EquationNote|4}} (i.e., 4).

which may be referred to by {{EquationNote|Eq. 5}} (i.e., Eq. 5).
