For any dimension vector , there exist the generic decomposition, and a dense and closed subset V of system space R〓 corresponding to this decomposition such that, for each dynamical system M∈V, every indecomposable summand of M thus M is clear.

对任意的维数向量，存在一般分解，以及系统空间Rm，n，p中稠密的开子集V，并且我们对V中每个系统的不可分解直和项知道得很清楚，进而对V中每个系统也非常清楚。

Based on this, to avoid using the Green′s formula on infinite domain, an infinitely differentiable function with compact subset is constructed and some important results to a especial solution of the inhomogeneous field equation are obtained.

在此基础上，为了避免使用无限区域上的 Green公式，通过构造紧支集上的无穷可微函数，获得满足非齐次控制微分方程的特解的重要结果。

Given a ring and a set of communication requests. Each request is represented by a pair of nodes, and associated with a profit. To satisfy a request in the undirected ring, we need to determine a path between the two nodes of the request in the ring. To satisfy a request in the directed ring, we need to determine a directed path from the source to the destination of the request in the directed ring. The goal of the call admission control problem is to determine and satisfy a maximum profit subset of the requests such that for every edge of the ring, the number of satisfied requests that are routed through the edge does not exceed the capacity of the edge.

要在无向环中实现一个呼叫，需在环中指定该请求所对应的两个顶点之间的一条路，要在有向环中实现一个呼叫，需在环中指定该请求的源节点到目的节点的一条路，环网络呼叫接纳控制问题的目标是确定最大利润的呼叫子集，在环中实现该子集中的每一个呼叫，使得经过每一边的呼叫的数目不超过该边的容量，对于无向和有向环网络呼叫接纳控制问题，我们均首次给出了多项式时间近似方案。

Firstly, we investigate the Dirichlet problems comparison principle on a bounded subset for this fully nonlinear intergro-differential equation, at the same time we must assume the measure in the intergro-differential item is absolute continuous.

首先研究这类完全非线性积分微分方程在有界区域上Dirichlet问题的比较原理，此时须假设积分项所涉及的测度是绝对连续的。

Methods 90 patients suffered from M.pneumonia were administered and divi ded into three groups:mild group, severe group, and normal control group. T cell subset parameters, natural killer cell and the serumsoluble interleukin- 2 recepter of all of above were determined.

方 法对90例住院的支原体肺炎患儿，根据其X线肺部受侵程度，分为重症组和轻症组，并设立了对照组，分别检测了各组极期和恢复期的T细胞亚群、血清可溶性白细胞介素-2受体(SIL-2R)及天然杀伤细胞数。

It is also possible to create double-ended chunks, where the committed region is any contiguous subset of the reserved region, with size equal to an integer multiple of the processor page size. These chunks can have both the bottom and top of the committed region altered dynamically.

另外还可以创建 double-ended chunk ，那么委托区将是保留区的任意连续子集，他的大小也是处理器页面大小的整数倍，这种Chunk的委托区可以有两个顶端和底端，并且它们的大小也是可变的。
