查询词典 newton

In the more narrow sense of science , as natural philosophy became linked to an expanding set of well-defined laws (beginning with Galileo's laws, Kepler's laws, and Newton's laws for motion), it became more popular to refer to natural philosophy as natural science.

在过去的19世纪，此外，还有增加的趋势准科学与研究自然世界。此举有时离开研究人类思想与社会在语言困境的本世纪末和到下一个。

The list starts with Archimedes and Kepler, whose three laws of planetary motion were not, incidentally, called "laws" by either him or Newton.

这些定律的名单起始于阿基米德和开普勒，后者的行星三大运动定律可不是被他自己或牛顿偶然地称为"定律"的。

Kepler's laws of Newton discovered the law of gravitation 10000 l ^ D has laid the foundation, then to the law of gravity, in turn, amended the third Kepler principle, namely, the ratio of 32 to strictly say no is a constant with the planets related to the quality of the l ^ D.

开普勒定律为牛顿发现万l^D有引力定律奠定了基础，而后，万有引力定律反过来又修正了开普勒第三定律，即比值32严格说不为常数而与行星l^D的质量有关。

In many ways, Galileo was a more modern thinker than Kepler (Galileo's contemporary) or Newton (whose single greatest accomplishment, apart from the invention of calculus, was the explanation of Kepler's three laws of planetary motion and their implications for the law of universal gravitation).

在许多方面，比起刻卜勒或牛顿（除了发明微积分外，牛顿的最大成就在於解释刻卜勒行星三大运动定律，以及它们在万有引力定律上的蕴意），伽利略是更现代的思想家。

Sitting before the computer, a process that lasts effectively for years may take place in a few seconds, the Kepler's and Newton's law are understood in a shorter time.

坐在计算机前边，持续多年的一个处理过程可以在几分钟之内发生，开普勒和牛顿的理论在短时间内就会被理解。

It is proved that the two-dimensional non-hydrostatic Boussinesq equations on the x ? z plane with the kinetic viscous term and the thermal dissipative term are unstable equations in the C 2 function class.2. If we replace the influence of the kinetic viscous term by Rayleigh friction and the thermal dissipative term by Newton cooling, the new generalized equations are stable equations in the C 1 function class. The construction of the solution space and the discriminating method for well-posedness of the problem of determining solution are given.

本文的主要结果如下：1证明了在y方向上均匀的带有运动粘性项以及热耗散项的两维非静力、Boussinesq近似的x-z面上两维旋转流体的控制方程组在C 2函数类中是一个不稳定的方程组。2如果以瑞利摩擦来代替粘性的影响，以牛顿冷却来代替热量的耗散，则所获得的一个新的方程组在C 1函数类中是一个稳定的方程组，给出了其解空间的构造和各种定解问题的适定性的判别方法。

The forces agreed; Newton says laconically,"I found the answer pretty nearly."

牛顿的说法简明扼要："我发现答案非常接近。"

The forces agreed; Newton says laconically "I found the answer pretty nearly."

牛顿简洁地说，"我离答案已十分接近。"

The forces agreed; Newton says laconically, I found the answer pretty nearly.

然而，两者之间只是接近而已：相似与接近是不可分割的，因为没有一种相似是绝对精确的。

Romberg first use of the method is integral for integration, Then the results obtained by using the interpolation method were obtained Lagrange polynomial interpolation polynomial interpolation and Newton, re-use of least squares fitting of thinking obtained polynomial, the last of these different types of polynomial, identify their respective strengths and weaknesses.

首先运用Romberg积分方法对给出定积分进行积分，然后对得到的结果用插值方法，分别求出Lagrange插值多项式和Newton插值多项式，再运用最小二乘法的思想求出拟合多项式，最后对这些不同类型多项式进行比较，找出它们各自的优劣。

In the days of sailing vessels the crew were afraid they would be becalmed on the ocean.

在使用帆船的时代，船员们担心他们会因为无风而无法在海洋上航行。

As long as foreign donors pay the PA's salary bill, few expect a new intifada.

只要外国继续为巴权力机构的薪水买单，希望发动新暴动的人便寥寥无几。
