牛顿

Numerically, Newton was saying that the mass of each cubic meter of earth was about 5, 000 or 6

从数值上说，牛顿所说的是地球每立方米的质量是5，000或6，000公斤。

Post-Newton metric was got inside and outside a uniform uncompressed ideal fluid oblate ellipsoid at rigid rotation.

As for the optimization problem, the damped Gauss-Newton Method algorithm is employed for obtaining its solution, and analysis the global convergence of the algorithm, also, the superlinear convergence rate and two order convergence rate of the algorithm is given.

对该优化问题，我们用阻尼高斯牛顿算法求解，并对算法的全局收敛性和超线性收敛速度进行了分析。

In this paper, based on the flexible multibody dynamics model of the virtual axis hybrid polishing machine tool, the differential — algebra hybrid equations is calculated by the Newton- Raphson method. The variety of the moving displacement, the velocity and the acceleration for the moving platform, leg, slider on the 3- PTT parallel mechanism and the pose curve of the series mechanism are obtained.

论文主要完成了在已经建立的虚拟轴混联研抛机床多柔体动力学模型基础上，应用牛顿—拉斐逊（Newton-Raphson）数值计算方法求解微分—代数混合方程组，得到3-PTT并联机构动平台、支杆、滑鞍各部件的运动轨迹、速度和加速度变化规律，以及串联机构的姿态变化曲线。

The parametric optimization model is established on the basis of explicit least square error, and the parameters of digital points are optimized by subspace interior reflective conjugate gradient method.

建立了基于显式的最小二乘重构误差的参数优化模型，运用子空间共轭梯度内部反射牛顿优化技术实现了大规模数据点的参数优化。

In the chapter 4, we discussed the generalized linear inversion method of direct current IP data from the angle of the least squares method. The computed speed of inversion can be greatly raised by calculating the partial derivatives matrix combining the reciprocity principle with Broyden\'s quasi-Newton method.

在第四章中，从最小二乘广义线性反演的角度，探讨了直流激电数据的广义线性反演方法；在偏导数矩阵的计算过程中，通过将互换原理与Broyden拟牛顿技术相结合的计算方式，可大大提高反演的运算速度。

So, what you've got is not Newton,but Pascal.

所以你抓住的不是牛顿，你抓住的是帕斯卡。

The modern understanding, of course, is that heat radiation is light, but Newton considered them two different phenomena (believing heat vibrations to be excited "when a Ray of Light falls upon the Surface of any pellucid Body").

现代的理解，当然就是热辐射光但牛顿认为他们两种不同的现象(believing热振是兴奋："当曙光落在表面的任何pellucid机构")。

The Apple Newton, released in August 1993, was the first popular hand held personal digital assistant.

苹果公司于1993年8月发布了牛顿，它是第一台比较流行的手持式个人数字助手。

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。
