There exist Engel groups for each of which the Engel length of the product of two elements is not bounded by any polynomial function of the Engel lengths of the factors.

定理1。每个团体存在的恩格尔恩格尔产物长度两个因素并不是什么北临多项式函数恩格尔长度因素。

Based on momentum theory and shock wave gas dynamic theory, jet equivalent body idea and bow sharp wave mathematic formula is brought forward.

利用动量定理和激波理论分析方法，提出了喷流等效体的概念，推导了等效体弓形激波方程。

Unitil fairly recently, Burnside's paqb theorem was another outstanding exemple of this.

特别地，Burnside paqb定理是一个非常出色的例子，它用特征标理论活得了证明。

Theorem and Burnside Theorem about p-nilpotence.

和Burnside关于p-幂零的定理。

For example, 2-order Taylor central finite difference is adopted in Yee format and 4-order in Fang format.

而Taylor级数展开定理是构造差分格式的一种重要方法，例如Yee格式采用二阶Tabor格式，Fang格式采用四阶Taylor格式。

The central limit theorem is a concentrated manifestation of providence.

中心极限定理是上帝旨意的一个集中体现。

A corresponding almost sure central limit theorem for a triangular array is proved.

同时，也得到了一个关于强混合组列的几乎处处中心极限定理。

Law of large number and central limit theorem are demonstrated and verified from the particular point of view by programming and plotting graphs.

笔者运用数学软件Mathematica作为工具，对大数定律及中心极限定理从不同角度进行演示与验证，给出形象直观的解释及说明。

By taking the energy integral as Lyapunov function, it is proved that nonlinear transverse vibrations of the beam undergoing uniform extension or retrieval are stable when there are not controlling moment in the central rigid body and driving force on the beam, according to the partial stable theorem.

利用能量积分构造Lyapunov函数，根据部分变量稳定性定理，证明等速伸展或收缩梁的横向非线性振动稳定。

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。
