As a graphical framework for formally describing interactive system, basic graph can represent processes and the interaction between processes in two ways: one is graphical representation, where a graph corresponds to a process and reduction in a graph corresponds to interaction between processes; the other is using term algebra consisting a set of terms and an equational theory on terms.

基本图是一种描述并发交互系统的形式化方法，它具有描述简洁、清晰和直观的特点。在基本图中，进程以及进程间的交互行为，既可以用图表示方法(其中一个图对应一个进程，图之间的归约对应进程之间的交互行为)，又可以用项代数来表示。

Based on rotation group algebra, a set of new methods for the expression of attitude error are provided.

基于旋转群代数，提出了一套姿态误差表示的新方法。

The classic concept of fuzzy convex, set theory methods will be used by the characterization of the classical algebra convex membership function with the theoretical approach to the promotion of fuzzy math to start a fuzzy convex studies.

1971年，经典模糊凸集的概念，将用集合论方法所刻画的经典代数中凸集的理论用隶属函数的方法推广到模糊数学中去，开始了模糊凸集的研究。

We also set up a Schur-Weyl duality between certain quantum group and Hecke algebra of type D_n.

我们还建立了某些量子群与D_n型黑克代数之间的Schur-Weyl对偶。

In the research to demand of International reserves,first, according to the affective character of demand to transition of International reserves, choosing the decision theory of Markov and dynamic transition equation as basic model, the paper has set up two transition methods--- stationary matrix and dynamic matrix, the later matrix has improved the sensitive reaction to time and velocity. Second, combining with knowledge of linear algebra, the paper has analyzed and testified the positive associated relation between transition matrix elements on main diagonal and the convergent speed of system, and explained why international reserves transition embodies the character under new situation and why the transition process can be accelerated by the strike of international idle money. Third,on the quantitative calculating to elements of transition matrix,referring to multiplication theory and decomposing-composing method of system, the paper has transformed main three-factor deciding confidence of international monetary into detail modulus by comparing analysis measure,now the matrix has been decided.

在国际储备的需求分析研究中，本文首先选择马尔可夫转移方程作为基础模型，根据需求对外汇储备结构的影响特点，提出非定常转移矩阵变换方法，拓展了马尔可夫变换对时间和速度的敏感性；结合线性代数知识，分析证明了定常转移矩阵的主对角线元素值的大小与系统的收敛速度的正向关联关系，并利用结论解释了国际货币新动向下外汇储备转换表现出的趋势特点以及国际游资冲击对国际货币结构变化的加速影响；在转移矩阵元素的量化计算上，本文参考乘数理论和系统分解合成原理，采用对比分析方法把影响国际货币信心的三大要素综合量化为转移偏好系数，然后根据转移偏好系数确定转移矩阵的元素值，其中还分别具体给出了定常转移矩阵和非定常转移矩阵的计算方法及在变换中的使用方法，从而不仅在定量分析上应证了定性分析结论，而且反映了随时间变化的美圆、欧元、日圆的比例结构均衡过程。
