在中心

The center of gravity is shown forward of the center of lift.

重力中心一般在升力中心的前面。

Early November this year, Pingxiang City completed the "green city planning system" through planning layout for the center City Green axle extension garden globe as tall as the external protective green around the center green expansion of the green corridor through, and realize the city in the mountains, water running throughout the city, creating artificial and natural combination of "natural music" style.

今年11月初，萍乡市编制完成了《城市绿地系统规划》，通过规划布局，使中心城区绿轴延伸，园林生辉，外围防护绿地环绕，中心绿地扩大，绿色走廊相贯，实现城在山中、水贯全城，创造人工与自然相结合的"山水绿城"风貌。

When the subjects wore shoes with different heel height and walked in different speed the ground reaction force and the track of the center of sole force were measured and analyzed quantitatively.

测量穿不同类型和不同鞋跟高度的受试者，在不同行走速度下地面反力的大小和鞋底压力中心，分析地面反力变化和鞋底压力中心轨迹。

At the present production conditions,the results of trials showed that centerline segregation and central porosity are improved.

对结晶器电磁搅拌改善大方坯质量进行了工业性对比试验，并对电磁搅拌参数进行了优化，在现有的工艺条件下，达到了改善铸坯中心偏析和中心疏松的目的。

At first, we give someelementary conception and properties of Novikov-Poisson Algebras, we elaborate on thegeneral conclusions about central extension and universal central extension in thechapter three.

我们首先给出了Novikov-Poisson代数的一些基本概念和性质，在第三章中详尽地阐述了中心扩张和泛中心扩张的一般结论。

Moreover if f is aperiodic, then f satisfies the local multidimensional central limit theorem.

在第三章中，对于满足某些条件的向量值的观察量，我们证明了多维中心极限定理和局部中心极限定理成立。

Probability of following after them, its central research topics are focused on promoting and improving the Bernoulli law of large numbers and central limit theorem.

概率论继他们之后，其中心研究课题则集中在推广和改进伯努利大数定律及中心极限定理。

By taking advantage of a corollary of the Desargues theorem and the corresponging extension of Desarguesian configuration, the concept of stereohomology has been defined in projective geometry and presented based on homogeneous coordinates. Consequently, a series of geometrical transformations, such as central projection, parallel projection, centrosymmetry, translation transformation, reflection, rotation transformation, which can be contained in it or derived from it have also been analytically defined.

利用Desargues定理的一个推论和引申的Desargues图形，给出"空间透射"在射影几何意义下基于齐次坐标表象的解析定义，从而解析定义了可蕴涵其中的中心投影、平行投影、中心对称、平移、反射等几何变换以及可由此衍生出的旋转变换。

The direction vector of benchmark at the beginning position is nz1＝nt1,when the middle gasbag follows along straight line, the coordinate of the centre of a circle is where d03 is distance of the centre of a circle between the middle gasbag benchmark section and drill mud head benchmark section.

The基准方向向量首先安置 is nz1＝nt1，当中间气囊沿平直的跟随line，圈子的中心的座标是 where d03是一个圈子的中心的距离在之间的 middle气囊基准部分和钻子泥朝向 benchmark部分。

Soon after mitosis, a procentriole is elaborated perpendicular to the parental centriole.

很快在有丝分裂之后，原中心粒被垂直地分裂成四个中心粒。

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。
