The shaped pulses were shown to be phase-sensitive at intensities too low to access different higher electronic states, and so these pulses apparently steer the isomerization through constructive and destructive interference effects, a mechanism supported by observed signatures of vibrational coherence.

脉冲形状被证明是在太低以至于不能进入不同的较高电子态的强度上对相位变化灵敏的，因此这些脉冲机制通过构成和破坏干扰反应操纵着异构化作用，这种机制由观测到的相干信号支持。

The thermolysis of the isomerized products derived from norbornadiene-coordinated carbonyl iron complexes gave two sorts of the thermolytic products based on different substituents on the olefin ligands. One is the corresponding diiron dimer complex, and the other is the complex in which the C-C bond of the cycloolefin ligand is broken.

变过形的脉冲在低强度下显得很敏感，这种强度很小，因此很难进入更高的电子状态。于是，很明显地，这些脉冲能给通过破坏性和建设性的干扰效应来操控异构化作用。观测到的振动一致信号更支持了这样一种机制。

The framework consists of such modules as dictograph, coordinator, task manager, repository. All these modules make an AM oriented PDM system an open, flexible and compatible system. Meanwhile, trusteeship is applied to AM oriented PDM so that a small or medium size enterprise can trust the Trusteeship Center with its product data.Based on the framework, this paper presents the function model of AM oriented PDM on view of Process but not of Product.

本文构建了基于多层Client/Sever模式的面向敏捷制造的PDM的系统框架，该框架通过任务侦听器、任务协调器、任务管理器和知识库等模块实现盟员系统的开放性、异构兼容性和自主性以及盟员系统间数据操作的协同性，并以数据托管中心为中小型企业提供一种产品数据托管方法。

The static model describes the relationship among user, permission and role and imports integrated inheritance to actualize the relationship between local role and global role. The dynamic model completes access control by session diffluence based on the static model. The actualization for the model is researched based on the analysis of the content and the rule of the model. A self-adapted RBAC wrapper based on agent model is presented according to the heterogeneous databases'demand for wrapper.

该模型比较全面地解决异构数据库系统的局部数据对象和全局数据对象的综合访问控制。I-RBAC模型包括静态模型和动态模型两个部分，静态模型主要描述用户、权限、角色（特别是全局角色与局部角色）之间的关系，动态模型是在静态模型中角色层次关系的基础上通过会话分流实现动态的访问控制。

However, due to the constraint and diversity of computing resources on mobile devices as well as dithered bandwidth and instability of wireless networks, traditional video coding techniques can not be directly used in mobile environment.

然而，由于移动设备计算资源的限制性和异构性，以及无线网络带宽的波动性和传输的不稳定性，导致基于Internet上的视频编码和传输技术不能直接有效的应用于移动环境。

Based on the heterogeneous knowledge units, the system can be used for real time meteorological data quality controlling. by use of the ontological analyzing technique, the entities and their relationship are analyzed to position the knowledge point for data checking and to improve the efficiency of knowledge acquiring from expert's experience.
