随机事件

The threat of emergency security incidents is increasingly extruded to people life security and society economy. Restricted by the territory and the economy, it is impossible to set up an integral medical aid post in each district. The medical rescue network system is put forward.

最后是对随机流动网络可靠性研究的一个实际应用的例子，突发公共安全事件对人类造成的威胁，由于地域和经济因素，很多区域无法建立完善的医疗救护站。

Study Selection Randomized controlled trials of any inhaled anticholinergic for treatment of COPD that had at least 30 days of treatment and reported on cardiovascular events.

文献纳入标准研究吸入抗胆碱能药物治疗COPD的随机对照试验，药物治疗时间不少于30天，并且报道有心血管不良事件。

But some important events can lead to brusque variations in price. To model this kind of phenomena, we have to introduce discontinuous stochastic process.

然而当一些重大事件发生时，市场价格会发生大的波动，为描述这种现象，这就要求我们引入不连续随机过程。

It contains random events and probabilities, random variables and their distributions, multi dimension random variables and their distributions, the number character of random variables, laws of large number and the central limit theorem, etc.

学习概率论的目的是对随机现象有充分的感性认识和比较准确的理解，初步掌握处理不确定性事件的理论和方法，培养学生运用概率方法分析和解决实际问题的能力。

In advance of reviewing probability for Senior Three students, the author gave an exam of probability. On the basis of analyzing the results, the author carried out a group of teaching strategies, the author reviewed the definition of Frequency by computer imitation trials and Equiprobability models by various Probability models, and distinguished Exclusive Events and Independent Events by examples, and described Variable Distribution by means of various Probability models.

在高三概率复习前夕，进行一次概率测试，在测试分析的基础上，采取有针对性的教学策略，利用计算机模拟试验复习频率定义；用各种模型进行古典定义的教学；运用实例辨析互斥事件与相互独立事件；借助各种概率模型描述随机变量分布列。

Secondly, the combination in concept and problem teaching can enhance profound comprehension of Exclusive Events and Independent Events. Finally, because Distribution is basic knowledge in teaching probability, meanwhile, the calculation for Expected Value and Variance also are based on Distribution. Thus, Distribution is the most important in teaching them, it needs to give more emphasis.

其中计算机模拟手段在概率的频率定义教学中效果明显，并且直观模型在古典概型教学中的作用也相当明显；其次，通过概念教学与解题教学的结合可以帮助学生深刻理解互斥事件与独立事件；最后，随机变量的分布列作为概率基础知识，期望以及方差的计算都是以分布列为基础的，因而，强化分布列的教学是这部分内容的重中之重。

The main contents of the course is as follows: events and their probability, random variables and their distributions, moments, point estimation and interval estimation, hypothesis testing, etc.

课程的内容主要包括：事件与事件的概率；随机变量的概率分布与数字特征；参数的点估计；区间估计和假设检验等。

The ability of the new modeling method in the description of logic relations and stachastic processes is proved, which indicates that such a kind of systems composed of components and in which any event has distribution parameters independent of system states, while its happening may depend on system states can be modeled by CRM method.

对这种模型方法的逻辑关系和随机过程的描述能力的给予证明，说明了CRM方法可以描述由部件组成，事件的概率分布参数与系统状态无关，事件的发生可以与系统状态有关的可靠性系统； 3。

If a fuzzy random event is described by the mapping on the measurable space,its meas- ure value can be calculated by the basic formulations which have been set up.

若一个随机模糊事件由定义在可测空间上的映射刻划，则可把已建立的基本公式用于求该事件发生的测度值。

Statistics The set of past events affecting a given event in a stochastic process.

过去发生的事：在一随机过程中影响一给定事件的过去发生的一组事件

He knows that he's one of the mostdominant players in the NBA right now.

我知道他现在是联盟里最有统治力的球员之一了。

Using analysis method of BCG , the dissertation analyzed the management of voluntary service organizations .

利用BCG分析方法对我国的志愿服务组织管理进行了分析。
