查询词典 newton

The finite difference is used to approximate differential operation; the reflectance map equation described by the first order nonlinear differential equation is transformed into an algebraic equation about the unknown surface heights, and then the objective equation is constructed by the reflectance map equation and gradient information of image. Moreover, the Newton iterative algorithm is utilized to obtain the numerical solution and 3D shape of the surface.

Leave it to the refrain of a campy, Oliva Newton John, 80's pop hit to clearly lay down an important principle of strong acting. Body language.

This problem, which was certainly known to the ancients, became especially acute in the seventeenth century with the invention of celestial mechanics, which first gave philosophers a certain picture of a way the world might be: it might be a world whose future states were entirely determined by the past and the laws of nature (of which Newton's laws of motion and law of universal gravitation served as paradigms).

这个从很早就被知道的问题，在十七世纪之后变得尖锐起来，因为引力力学第一次给予了哲学家一个明确的世界图景：可能世界的未来事态完全可以被过去和自然律（Newton的运动律和万有引力定律是范例）所决定。

He now lives and works in New York, as Executive Editor of Photo district News, the monthly magazine for professional photographers based in New York City, and Executive Editor of PIX. His favourite photographer of all time is Helmut Newton.

他现在在纽约居住和工作，作为执行编辑图片区新闻，该杂志在纽约是每月出版的，他最喜欢的摄影师是Helmut Newton。

The collisions of rigid bodies is a classical problem, however, the coefficient of restitution is used in the conventional researches to study this problem. The authors present a new way for this kind of problem. A theory of the collision between two rigid bodies in two dimensions, taking account of friction, is proposed according the Newton first law. And the shortages of former researchers are justified.

刚体碰撞是力学上的一个经典问题，但目前大都采用给定恢复系数进行分析的方法，本文则直接从两刚体碰撞时Newton第二定律出发，建立了计及摩擦的两刚体碰撞基本理论，并指出了以往研究通过给定恢复系数方法的错误之处。

While they share Newton's faith that the universe is ruled everywhere by a coherent set of rules, they cannot say, as scientists, how these particular rules came to govern things.

尽管他们都与Newton持有相同的信念，即宇宙由一套规则掌控着，但是他们不能说出，某些特定的规则如何支配宇宙中的事物。
