查询词典 limit theorem in probability theory

In this paper,starting with the concept of risk,trying to take the theory of probability,central limit theorem,definition of optimal statistic estimate and economic theory as the basis and according to the concrete situation of the natural gas exploration project,the formula to quantitatively determine the risk is derived.

文章从"风险"的概念入手，尝试以概率论、中心极限定理、最优统计估计量的定义和经济理论为基础，结合天然气勘探项目的具体情况，推导出了定量测定风险的公式。

Large numbers law and center limit theorem in probability theory are simulated randomly by Microsoft Excel software in this artcle,the visualizing of them are easily achieved by computer.

作者采用Microsoft Excel电子表格软件对概率论中的大数定律和中心极限定理进行随机模拟，在计算机上很容易实现了这两个定理的可视化。

This paper put forward two methods of constructing randomizer in the Fractal applications:(1) The randomizer satisfing the Gauss normal distribution N(0,1) is constructed basing on central limit theorem of the probability theory;(2) The random sequence is created basing on the Chaos principle. There is not only randomness inside the random sequence but also in random sequence itself.

提出分形理论应用中构建随机数发生器的两种方法：根据概率论的中心极值定理，产生服从高斯正态分布N(0，1)的随机数；基于混沌学原理产生随机数，不仅随机数序列内部有随机性，而且随机数序列本身也具有随机性。

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。
