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.

例如，一类线性代数的推广形式在凸双重函数中发展起来，而凸双重函数是线性变换的类似情况，凸集和凸函数的内积是根据 Fenchel 对偶理论的极值定义的。

Difference set is one kind of unbounded difference poset. The existenceof the tensor products of two cancellative difference sets are investigated. It isproved that the tensor product of a Boolean algebra and a cancellative differenceset always exists.

作为差分偏序集无界推广的差分集，我们研究了它的张量积问题，证明了任何消去差分集和布尔代数的张量积一定存在。

People had always considered the problem of selecting dynamically threshold as a problem about measure of fuzziness of fuzzy sets, but they did not notice that it is essentially comparison of elements in an algebra structure, and thereby regarded mistakenly order homorphism (partial ordered set to totally ordered set) as order isomorphism.

本文从模糊系统理论和代数理论的相关思想出发，在序结构的观点下从理论上对模糊度的不一致性进行了详细的分析，提出了模糊度计算公式选用的统一标准，进而结束了随意选用模糊度计算公式的混乱状态。

Basic linear algebra in MATLAB . Vector and matrix addition and multiplication. Solving sets of linear equations using matrices.

使用MATLAB软件中的基础线性代数、向量和阵列的加法与乘法，以及使用阵列解决多组线性方程式。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
