摘要针对传统的事件树／故障树分析方法的局限性，提出了基于贝叶斯网络的系统概率安全评估方法。

According to the deficiency of event tree analysis in safety evaluation,this paper introduces a dynamic event tree analysis method and the mathematical description is given as well.

针对传统的事件树分析方法在安全性评估中的局限性，在动态事件树分析方法的基础上，给出了其数学描述，并将其应用于导弹安全自毁系统安全性评估中，以描述导弹安全自毁过程中的动态特性。

If modifications occur to the tree during event processing, event flow will proceed based on the initial state of the tree.

如果在事件发生过程中结构树发生可变化，事件流还是会按照结构树的初始情况继续下去。

At present the fault tree or event tree method is generally applied to calculate the probability of ship grounding, and the certain probability is used to represent the failure probability of basic event.

Based on the concepts of complex product, standard operation, virtual operation, no-wait and the expansion processing tree defined in this paper, the standard operations are processed by allied critical path method and best fit scheduling method, and the virtual operations are processed respectively on corresponding machine with movement and exchange algorithm in order to translate scheduling problem with no-wait operations into the general scheduling problem with virtual operations.

该方法在提出复杂产品、标准工序、虚拟工序、零等待和扩展加工工艺树的概念基础上，对扩展加工工艺树中的标准工序采用拟关键路径法和最佳适应调度的车间调度算法进行调度，对虚拟工序采用移动交换算法在相应设备上分离调度，将存在零等待约束的调度问题转化为存在虚拟工序的无零等待约束的调度问题。

这两棵树的树顶树枝相互交织在一起。

According to the example, this is an efficient approach over FTA, but also it can handle diagnosis reasoning and exculpation reasoning and that FTA cannot.

实例表明，该方法不但比故障树分析更有效，而且能进行故障树分析不能进行的诊断推理和辩解推理。

The influence of the bark layer and trunk radial and height and the ratio of interior radius and exterior radius and ground elevation angle on scattering pattern is investigated.

第二，基于Monte-Carlo模拟技术，用相干叠加近似、树的独立散射近似和独立散射近似等方法，计算了倾斜或水平粗糙地面上分形树的电磁散射。

The paper proposes a method of use of hash and binary tree to express the internal structure of knowledge and use of hash table and B tree to store the external knowledge for the first time.

首次提出用散列二叉树实现知识的内部表达；用散列表和B树实现知识的外部存贮，这种方法提高了知识的存取效率，实现了知识库的分布存贮和多用户共享。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
