释义	bounded variation Mathematics A real function f on an interval [a,b] is said to have bounded variation if the set of values $\sum_{i = 1}^{n} \| f (x_{i}) - f (x_{i - 1}) \|$ is bounded above where a = x₀ < x₁ <…< x_n = b is any partition of the interval. Differentiable functions with bounded derivatives have bounded variation. xcos(1/x) is an example of a function which does not have bounded variation.
