查询词典 event probability

For that question: how a probability event becomes to be a certainty event after some time.The answerer is that the Probability is changing along the development of time since many factors will affect the Probability in that time interval and Probability=1 at the point it happened.

又如生化反应，在刚开始的时候，那些化学物质发生反应的概率可能很小，加入催化剂（或者即使不加入催化剂，由于各物质的溶度随着反应进行，时间的推移而改变）影响着后来某一时刻这些化学物质能否完全反应。

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.

目前，计算船舶搁浅的概率时常采用故障树和事件树方法，以确定的概率数表示底事件的发生概率。

In this paper the event tree is used in the analysis on cascading failures and by use of probability approximation theory of rare event the probability order of multiple failures is divided, thus the screening process of multiple failures can be simplified.

文章采用事件树对连锁故障的分析方法，运用小概率事件的概率近似理论对多重故障进行概率阶次划分，可以简化多重故障的筛选过程。

A very small or impossible event can be referred to as "small probability event" according to the probability theory of higher mathematics in c

记得大学时期高等数学概率论课本上把某种极小的可能甚至不可能发生的事件称为"小概率事件"。

An impossible event has a probability of exactly 0, and a certain event has a probability of 1, but the converses are not always true: probability 0 events are not always impossible, nor probability 1 events certain.

一个'不可能'事件其机率值为0，而'确定'事件其机率值则为1。但反推并不成立，也就是说机率值为0的事件不表示它就是一个'不可能'事件，同理，机率值为1的事件不表示它就一定发生。

An ''impossible'' event has a probability of exactly 0, and a ''certain'' event has a probability of 1, but the converses are not always true: probability 0 events are not always impossible, nor probability 1 events certain.

但反推并不成立，也就是说机率值为0的事件不表示它就是一个'不可能'事件，同理，机率值为1的事件不表示它就一定发生。

Fast composite-event probability algorithm with both linear time and space complexity is proposed.

提出了一种可应用于电力系统充裕度分析的快速组合事件概率求取方法。

Discovering passage of event happened by tracing along terminal point of event on probability tree, utilizing multiplication formula and addition of probability again, the probability of an event may be caculated and some problems that students grasp with difficulty and make easily mistakes can be solved.

用概率树法求事件发生的概率，只需在概率树上沿事件的终点向前回溯，便可以发现事件发生的通道，再利用概率的乘法公式和概率的可加性，就解决了概率论中学生很难掌握的、容易出错的问题。

For this purpose, the safety state of the structure is regarded as a fuzzy set in the universe of discourse of the structural state, i.e. the safety event is considered as a fuzzy event and the mathematics model of the fuzzy event probability is adopted to be a unified model of the structural reliability analysis.

为此，本文将结构的安全状态看作是结构状态论域中的一个模糊集合，即认为安全事件为一模糊事件，采用模糊事件概率的数学模型作为结构可靠性分析的统一模型。

This text makes use of the diagram of Venn, changing abstract probability into the direct- viewing diagrams. It is completely to explain how to use the diagram of Venn to show the relation of events and the area of the diagram express event probability.

本文将利用数形结合的思想，把抽象的概念转化为直观的Venn图，并将全面完整地阐述如何利用Venn图表示事件之间的关系，图形的面积表示事件的概率。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
