例句

That leaves CPT symmetry: the equivalent of what you would see if you watched a movie that starred antiparticles run backward in a mirror.

最后，剩下CPT对称：就像如果电影里的演员是反粒子，然后你透过镜子，观看倒著放的电影。

Clearly, many of these antiparticles must be annihilated when they meet particles of ordinary matter.

显然，这些反质子中的大多数一定在他们遇到正常物质的粒子的时候湮灭掉了。

Some radioactive substances emit positrons, the antiparticles to electrons, and are used in PET (positron-emission tomography) scans.

有些放射性物质会放出正子，它是电子的反粒子，已经应用于正子断层扫描（PET）。

Particles and antiparticles could still collide, however, since gravitational repulsion is much weaker than electrical attraction.

粒子与反粒子仍然存在碰撞的机会，因为万有斥力要比电极引力弱得多。

DIRECT TESTS FOR CPT violation can be performed by comparing properties of particles and antiparticles .

要直接测试CPT违逆，可以利用粒子与反粒子间的比较。

The symmetry between particles and antiparticles is woven deep into the foundations of physics.

粒子与反粒子间的对称性深深地锲入到物理学的基础之中。

Another major problem in cosmology is what has caused the universe to contain more particles than antiparticles.

宇宙学的另一主要问题是解释为什么粒子要多于反粒子。

The scientists also want to compress large clouds of antiparticles into high-density clumps that can be tailored for practical applications.

科学家们还希望能将大片大片的反粒子云压缩为高密度的反粒子块，以便进行实际应用。

One notion regarding dark matter particles suggests they have antiparticles, meaning they annihilate each other on contact.

一种关于暗物质颗粒的观点认为：暗物质颗粒本身存在反粒子，这意味着它们互相接触后互相自行抵消。

In the same way the proton and neutron should also have their corresponding antiparticles.

同样地，质子和中子也应该有对应的反粒子。

the convention for antiparticles uses such time-reversed arrows.

Another idea suggests that dark matter particles are their own antiparticles.

另一种观点认为：暗物质颗粒同时也是自己的反粒子。

Antimatter is matter that is composed of the antiparticles of those that constitute normal matter.

反物质是由那些常态物质构成的反粒子组成的物质。

Fewer than zero particles being present usually means that you have antiparticles instead.

粒子少于零通常意味着这里存在着反粒子。
