Others might be data feeds such as those from organisations like reuters or bloomberg , where the order in which data arrives is uncontrollable by the user 其他数据源可能是一些数据填充，例如reuters或bloomberg之类的组织中的数据，其中数据到达的顺序是用户不可控的。
The series h - bridge multilevel converter ' s power circuit is composed of uncontrolled rectifier with filtering capacitor and single phase h - bridge voltage - type inverter 串联h桥多电平变频器的主回路从结构上可分为三相电容滤波不可控整流电路和单相电压型全桥逆变电路。
Secondly , for the petri nets controller synthesis of des , linear integer program ( lip ) is an efficient technique for the on - line computation of the control policy when the maximal uncontrollable subnet is loop - free 当最大不可控子网是无环结构时，线性整数规划( lip )是一种非常有效的在线求解控制律的方法。
The existing host - based prevention technology can do nothing to prevent these infected nodes , and the quarantine mechanism can only limit the propagation range and can ’ t eliminate all of the worms 现有的基于主机的防护技术对这些感染蠕虫的不可控节点无能为力,而隔离技术只能缩小这些节点的危害范围,无法彻底清除节点中的蠕虫。
This paper discusses the relative efficiency analysis of the dea model with uncontrollable inputs and undesirable outputs under circumstance restriction and proposes the definitions and theorems about the relative efficiency of decision making units ( dmus ) 摘要对环境约束下包含不可控输入、非期望输出的dea综合模型的相对有效性进行研究，给出决策单元有效的定义及定理。
In this paper , for the maximal uncontrollable loop - in subnet with a special form , the maximal permissive control policy is obtained through applying the lip to the loop - free subnet that is equivalent to the maximal uncontrollable loop - in subnet 本文针对一类最大不可控子网有环的petri网，通过把有环的最大不可控子网等价为无环不可控子网进而应用lip方法来得到最大容许控制律。
The lip is suitable for the case that the uncontrollable subnet is cascade petri net and all cascade subnets are either acyclic petri nets or state graphs , and control laws can be calculated using some standardized mathematical tools 线性整数规划法适用于不可控子网是序状petri网， _且.各序状子网要么是无环网，要么是状态图的场合，该方法的优点在于在数学上有一标准的求解工具。
Environment is incontrollable for its complexity and externality , so it is essential of harmonizing relationship between development and environment to change humans concept and adjust human ' s behavior , and its key is harmonization of relationships between person and person 环境的复杂性与外在性决定了其的不可控性，因此，协调环境与发展的实质是转变人的思想观念与调节人的行为，关键是协调人与人之间关系。
Chapter 2 clarifies some basic concepts and the point of view in this essay , and sets criterion of crisis classification . chapter 3 : classifies potential crisis in scenic spots " development into there types : outside controllable crisis , inside uncontrollable crisis and interaction crisis 第三章：将景区景点发展中的潜在危机分为不可控的外部危机、可控的内部危机与内外交互作用危机三大类，分别有所侧重的分析了各类危机的表现形式、成因及影响。
Internet worms are difficult to eliminate because internet is an open and complex scale - free system , and there are a mass of vulnerable nodes , which are absent of managing and defending . if these nodes are infected with worms , worms will be left on them and may attack the other nodes on internet 网络蠕虫之所以难于控制主要是由于internet本质上是一个开放的复杂巨系统,其结构复杂,缺乏中心控制能力以及其开放性的特征导致存在大量网管层面上的不可控节点。
