不操作

Then,a new result of quantum mechanics is given:considering an arbitrary manipulation of one EPR particle,which can be modeled in fullgenerality as a unitary interaction of that particle with an outside system or ancilla,ini-tially in a pure state,we shall show that such interactions can be used to prepare all andonly those states of the joint system(two particles in arbitrary entanglement and theancilla)that yield unperturbed marginal statistics for all measurements on the anotherparticle,with which the ancilla did not interact.

首先，我们介绍了量子通讯的概念是如何被引入的；其次，我们给出了一个新的量子力学结果：制备一对EPR粒子，然后把它们分开，如果我们对其中的一个粒子进行操作，那么该操作将不会改变另外一个粒子的单独测量的期望值。

It is important for the application of formal approach and formal specification in all stages of software development to study and design automatic refinement from Z to high-levellanguage: Insure complete formalization in all stages of software development; Avoid antilogy in refinement due to mistaken operation or computative mistake and insure consistency and integrity of system; Due to avoiding manual operation in refinement process, it is feasible to bulid a compile environment that Z specification automatic refine and form high-level programme, this will accelerate the promotion and application of Z in industry.

Z到高级语言自动求精的研究与设计对于形式化方法及形式规格说明应用于软件开发的各个阶段具有非常重要的意义：确保了从需求分析阶段开始的软件开发周期的完全形式化；避免了人工的误操作或演算错误导致的求精前后不一致，保证了系统的一致性和完整性；由于求精过程避免了手工操作，因而Z规格说明自动精化为程序代码的编译环境可以建立，这将会加速Z规格说明在工业界的推广应用。

Operation cannot be performed while async operation is pending.

不能在异步操作挂起期间执行操作。

The technical ability request of this system's operation to customer isn't high, knowing the personnels of the calculator basic operation a little bit will use that system, the school which suited for various layer transacts.

另外，本系统队用户的操作技能要求不高，稍微懂得计算机基本操作的人员都会使用该系统，适合于各种层次的学校办公。

In other words, when a branch in the code the computer was processing occurred (that is, there is an unanticipated call to another section of the program that necessitates another call to memory), instead of stalling the pipeline to retrieve the instructions that were branched to, the computer added a delaying instruction behind the branch that either did something useful while the other instructions were called, or at worst did nothing at all.

换句话说就是，当计算机执行的代码中出现了分支(就是说，发生了不可预料的对程序中其他程序段的调用，即必须实现一个新的访问存储器的操作)时，计算机不是停止这条流水线的工作去修复被分解的指令，而是在这个分支指令后增加一个延迟指令，该指令在其他指令被调用时，要么做一些有用的事情要么执行空操作。

Based on a component model of application system in which three types of the basic components are discussed, this paper first focuses on the "semantic" interoperability among components, and presents a Primitive-Semantic component constructing method through a semantic model to deal with the semantic interoperability while the communication protocol among components doesn't exist. It then presents a composable Distributed Virtual Reality Component-Based Architecture, including its key mechanism and algorithms.

指出分布式虚拟现实系统中存在的3种基本构件；重点讨论构件的"语义"互操作问题，通过建立构件的语义模型，提出一种原语-语义构件的构件构造方法，该方法可以解决不存在通信协议情况下的构件之间"语义"互操作问题；给出一种支持可组装的分布式虚拟现实应用系统的基于构件的体系结构以及其中的核心机制和算法。

Two features of these operations are apparent immediately: firstly, a large number of users must be able to operate at the same time without interfering with each other, and secondly, the distances over which the system must provide communication need not in general be great, since much of the system's operation will be either within the confines of a conurbation or along well-defined major vehicle trunk routes or railway lines.

这些部门的两个特征立刻就明显了：第一，很多的使用者必须能够在没有干扰彼此的情况下同时操作，第二，系统所能提供交流的距离大体上不需要太长，因为许多系统的操作是在大都市的边界里面或沿着明确限定的主要车辆主干路径或铁路线。

The factors that have effect on the packing fixed weight of polyester staple were analysed from the aspects such as the desigh defects of the cutterhead,the inaccuracy of the measurement and the not standard operation.

通过对刀盘设计缺陷、计量不准、操作不规范等影响涤纶短纤打包定量率因素的分析，找出了改进措施，如改造刀盘、调整切断机速度、优化计量控制仪参数、规范日常操作等，从而使涤纶短纤打包定量率由30%提升到98%。

If stering is provided by articulation: 1, it shall comply with item 1 in all operating situations, and shall not cause unstable displacement or trapping of the operator

操作应在以下的明确度下进行：1 应遵守所有的操作规程，并避免不稳定的换人或操作者被困，无法摆脱机器或机器失控

In the process of electro-membrane filtration, the applied operation condition and membrane do not have significant electroosmosis effect through related experiment. Under the operation of 98KPa pressure, only 6% flux was increased, which showed the increase of flux in the applied electric field process mainly from electrophoresis effect. The effect of dye filtration by membrane is mostly influenced by the basic nature of dye, including size of molecular weight, electrophoresis motility and the adsorbability of dye to membrane.

在外加电场薄膜程序中，所用的操作条件以及所使用的薄膜，经电渗透实验显示电渗透的效应不明显，而在98KPa压力操作下，也仅增加6%的通量贡献，显示外加电场程序通量之提升主要来自电泳作用；薄膜过滤染料的效果主要受到染料基本性质的影响，包括分子量大小、电泳动能力与染料对薄膜的吸附能力。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
