单词 Strong Nuclear Force
释义

Strong Nuclear Force

原声例句
TED-Ed(视频版)

A phenomenon known as the strong nuclear force struggles to overcome this repulsion and keep the nucleus intact.

一种叫做强核力的现象艰难地克服这种排斥并保持原子核完整。

经济学人-科技

These, despite being mutually repulsive because they are positively charged, are held together by a phenomenon called the strong nuclear force.

虽然质子之间因带正电荷而相互排斥,但被强核力聚集在一起。

奇思妙想科学站

We'd have to find a way to make use of one of the fundamental forces of nature - the strong nuclear force.

我们必须找到一种方法来利用自然界的一种基本力量——强大的核力。

Crash Course 综合篇

Well, one of the four fundamental forces of physics is the strong nuclear force, an attractive force that acts between protons and neutrons in a nucleus.

好吧,物理学的四种基本力之一是强核力,这是一种作用在原子核中的质子和中子之间的吸引力。

经济学人 Science and technology

Bosons include photons, which carry the electromagnetic force (and are the particles of light), the aforementioned w boson, the gluons that hold atomic nuclei together via a second, strong nuclear force, and the Higgs.

玻色子包括携带电磁力的光子( 并且是光的粒子) 、前面提到的 w 玻色子、 通过第二强核力将原子核保持在一起的胶子, 以及希格斯粒子。

经济学人 Science and technology

They are more excited about having two independent ways of measuring time: atomic clocks, which depend solely on the electromagnetic force governing the electrons' movement; and nuclear clocks, which also obey the strong nuclear force.

令他们更为兴奋的是, 有两种独立的计时方式:原子钟,仅依赖于控制电子运动的电磁力;核钟, 也遵循​​强核力。

时间简史(原版)

The success of the unification of the electromagnetic and weak nuclear forces led to a number of attempts to combine these two forces with the strong nuclear force into what is called a grand unified theory (or GUT).

电磁力和弱核力统一的成功导致了许多尝试,将这两种力与强核力结合起来,形成所谓的大统一理论(或GUT)。

强相互作用 Strong interaction

(重定向自Strong Nuclear Force)
氦原子的原子核,因为残留强相互作用的影响,二个质子虽都带正电,但仍不会互相排斥
一个质子和中子之间核力(残留强相互作用)的动画。小的成对出现的彩色小圆圈是将质子和中子束缚在一起的胶子,胶子也可以固定Π介子中的夸克和反夸克,因此可以在二个强子之间产生残留强相互作用。反夸克的颜色用这个图来表示。若要看较大的图,可以看这个图
质子和中子绕射的费曼图,中间产生了π介子
上述的费曼图,但标示所有的夸克,表示强作用力运作的方式。其中的直线是夸克,而由几个不同颜色圆形组合,类似橡皮筋绳的是胶子,其他在质子、中子π介子中固定的胶子省略不画出

强相互作用是作用于强子之间的力,是所知四种宇宙间基本作用力最强的,也是作用距离第二短的(大约在 10 m 范围内,比弱交互作用的范围大)。另外三种相互作用分别是引力、电磁力及弱相互作用。核子间的核力就是强相互作用。它抵抗了质子之间的强大的电磁力,维持了原子核的稳定。强相互作用也将夸克基本粒子结合成为质子及中子等强子,这也是组成大部份物质的粒子。而且一般质子或中子里,大部份的质能是以强相互作用场能量的形式存在,夸克只提供了1%的质能。

强相互作用可以在二个地方看到:较大的尺度(约1至3飞米)下,强相互作用将质子及中子结合成为原子的原子核,较小的尺度(约0.8飞米,约为核子的尺寸)下,强相互作用将夸克结合,成为质子、中子或其他强子。强相互作用的作用力非常强,大到束缚一个夸克的能量可以转换为新的夸克对的质量,强相互作用的这个性质称为夸克禁闭。

Strong interaction 强相互作用

(重定向自Strong Nuclear Force)
The nucleus of a helium atom. The two protons have the same charge, but still stay together due to the residual nuclear force
An animation of the nuclear force (or residual strong force) interaction between a proton and a neutron. The small colored double circles are gluons, which can be seen binding the proton and neutron together. These gluons also hold the quark-antiquark combination called the pion together, and thus help transmit a residual part of the strong force even between colorless hadrons. Anticolors are shown as per this diagram. For a larger version, click here
质子和中子绕射的费曼图,中间产生了π介子

In particle physics, the strong interaction is the mechanism responsible for the strong nuclear force (also called the strong force, nuclear strong force), one of the four known fundamental interactions of nature, the others being electromagnetism, the weak interaction and gravitation. Despite only operating at a distance of a femtometer, it is the strongest force, being approximately 100 times stronger than electromagnetism, a million times stronger than weak interaction and 10 times stronger than gravitation at that range. It ensures the stability of ordinary matter, confining quarks into hadron particles, such as the proton and neutron, the largest components of the mass of ordinary matter. Furthermore, most of the mass-energy of a common proton or neutron is in the form of the strong force field energy; the individual quarks provide only about 1% of the mass-energy of a proton.
