定义的

Basing on the traditional definition about trip-chain, the paper has defined a start point and end point standard in the commuters on-off duty trip-chain, and by utilizing the analysis method which based on trip-chain, the paper presents the discrepance about trip-chain type selection behavior as the commuter has different socity and economy background.

Bonikowskis model, the covering upper approximation operation and covering lower approximation operation are not dual to each other. William Zhu proved them determining each other, but he cannot give the quantity relation of them.

Bonikowski定义的广义覆盖粗糙集模型中，上近似算子与下近似算子不满足对偶的性质，虽然William Zhu等证明了上、下近似算子是相互确定的，但是没有给出它们之间具体的数量关系。

For example,a generalization of linear algebra is developed in which "convex bifunctions" are the analogues of linear transformations,and "inner products" of convex sets and functions are defined in terms of the extremal values in Fenchel's Duality Theorem.
