In addition, access control policies of aggregated resources can be formulated as expressions of the algebra. Several algebraic properties of policy expressions are discussed. It shows that the algebraic properties of policy expressions can be used to verify whether policy composition results meet the protection needs of each party.

用代数表达式形式化地描述聚合资源的访问控制策略，讨论了策略表达式的若干代数性质，说明可借助策略表达式的代数性质去验证策略合成结果是否符合各方对聚合资源的保护性需求。

Aiming at OQL, we treated type as monoid (collection monoid and primitive monoid), and used monoid comprehension as OQL's intermediate representation. Therefore we can merge the rewrite rules for a number of collection types, then employ monoid comprehension in defining algebraic operators, as cut out the limit that in relational algebra/calculus algebraic operators are only for set.

针对ODMG-2.0的对象查询语言OQL，我们把类型提高到幺群级，然后从幺群概括入手，用幺群概括作为OQL的查询中间表示，统一了多种聚集类型的重写规则，幺群概括还被我们用于定义代数操作符，这使得代数操作符突破了关系代数/演算中只针对集合的局限。

Now that the L-valued fuzzy state automata has such powerful computation capacity, it is necessary to traverse the algebraic properties such as transformation semigroups,products and covering relations in L-valued fuzzy automata in order to show the close correspondence between the algebraic properties and the latticeordered monoid.

既然格值自动机具有如此强大的计算能力，有必要对其从代数角度出发较详细地，较深入地研究此类自动机的变换半群，乘积和覆盖关系，揭示此类自动机的代数性质和格半群间的紧密联系。

Applying multivariate spline theory which was established by Wang RenHong in ( [1] , [2] ), the Nother theorem of algebraic curve [71] is generalized to the piecewise algebraic curve.

1：利用王仁宏在文献（[1]，[2]）中关于多元样条函数的基本理论，本文将代数曲线的Nother定理（[71]）推广到分片代数曲线上，给出了剖分为〓，和星形剖分上的C〓分片Nother型定理。

Different from previously presented threshold RSA signature schemes, this new scheme can effectively avoid computation of any element\'s inverse in any algebraic structure such as Z_(φ and Z_N, which makes the complicated algebraic extension, parameter constraint and inversion pre-computation all unnecessary.

该体制基于整数矩阵运算，不需要对任何非域代数结构中的元素求逆，为构造高效实用的门限RSA签名方案奠定了基础。

First, a simple criterion on the delay-independent asymptotic stability has been derived in the form of the algebraic Riccati inequality and algebraic Riccati equation for the linear systems with time-varying multi-state delays.
