又因为这些模型考虑了多种因素的影响所以它们具有较大的适应性和可推广性。

Contemporary natural science, especially the development of the foundation academics at the macro view and tiny view two directions up, all having already outrun what daily life be familiar with and used Newton the classic mechanics and rigid space far and far can explain of scope.

当代自然科学，特别是基础学科的发展在宏观和微观两个方向上，都已远远超出日常生活所熟知的、用牛顿经典力学和刚性空间可以解释的范围。

And that rippling ring may be proof that Newton and Einstein were right after all.

这种荡漾着的环形物质也许就是牛顿和爱因斯坦仍然正确的证据。

Roentgen because one of the film was sensitive, aware of the existence of X-ray, and ultimately won the first session of the Nobel Prize, Newton because of a falling apple and discovered gravity.

伦琴因为一张被感光了的底片，意识到X射线的存在，最终获得第一届诺贝尔奖，牛顿因为一只落下的苹果而发现万有引力。

Newton took Yao-yao over to the campus. It was full of traditional Roman style buildings with tall columns and roofs. Each column was decorated in Corinthian style. It was so splendid and grand looking.

牛顿领著瑶瑶参观了他的校园，典型的古罗马建筑，高大雄伟的巨柱和穹顶，每个柱子的顶端又采取"哥林多"式的雕刻作为修饰，雄伟而壮观。

The calculation of the rotordynamic coefficients of a multistepped annular seal in hydraulic turbines is discussed in this paper. Based on the Hirs' turbulence lubrication theory and the bulk flow model, the governing equations for the flow in the seal are developed by using the Moody's friction equations. The governing equations are perturbed when the rotor and the stator are coaxial. The Runge Kutta integration method and the Newton Raphson iteration method are used to solve the perturbation equations....

本文首先在Hirs紊流润滑理论的基础上，采用体积流动模型及Moody摩擦方程建立起阶梯口环水封中流体流动的控制方程，将各个方程在转子与定子同心处进行摄动，采用Runge－Kuta积分法及迭代过程求解摄动方程，建立起水轮机阶梯式口环水封的转子动力特性系数的计算方法，为水轮发电机组轴系的动力学分析提供了必要的理论基础。

Newton 's laws are meaningless equations until we know how to apply them.

倘若我们不知道怎样应用牛顿定律，这些定律就会是一些没有意义的方程。

We use quasi-Newton method for a high-speed coarse scan over a large area of the head, and Levenberg-Marquardt method for a fine scan near the source area.

首先从数学物理中关于不定问题的定义来解释脑磁逆问题的不适定性，脑磁文献中没有这方面的详细讨论。

Even Newton's laws are preceded by eight definitions and a "scholium", or explanatory comment, asserting that space, time and motion are absolute.

即便是牛顿定律，也是建立在8条定义和一项注释基础上的，这项解释性注释说空间、时间及运动都是绝对的。

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。
