查询词典 antiparticle

The symbol used to denote an antiparticle is the same symbol used to denote its normal matter counterpart, but with an overstrike.

过去常用于表示一个反粒子的符号是以用来表示它的常态物质版本的相同符号，仅有少许不同。

Vacuum fluctuations are always created as particle/antiparticle pairs.

真空涨落一直产生粒子和反粒子对。

The antiparticle of the electron.

正负电子相互碰撞的加速器。

Similarly the positively charged proton has a negatively charged antiparticle, the antiproton.

同样的，带正电荷的质子具有其带负电荷的反粒子—即反质子。

In the "indirect" process, first observed in neutral kaon particles in 1964, quantum mechanics allows particles to change into their antiparticles and back again in a process known as "mixing". In 2001, The BaBar team, working at the Stanford Linear Accelerator -- and independently the Belle collaboration at the KEK laboratory in Japan -- were the first experiments to detect this in a B meson. BaBar observed "direct" CP violation in 2004 by showing that the number of decays observed for B mesons was higher than for their antiparticle equivalents.

在&间接&过程中，量子力学允许粒子在一种被称为&混合&的过程中，在自身与其反粒子之间相互转变。1964年人们第一次在中性K介子上观测到这种现象。2001年，在斯坦福直线加速器中心工作的BaBar研究组和另一个日本高能加速器研究中心的Belle研究小组各自独立地第一次在实验中观测到这种现象发生在B介子上。2004年，BaBar小组观测到了&直接&电荷宇称不守恒，他们发现观察到的B介子的衰变数量要高于其对应的反物质。

The polarised photons were able to take the place of the particle and the antiparticle in Dr Hardy's thought experiment because they obey the same quantum-mechanical rules.

极化的光子可以代替哈代的假想试验中的粒子和反粒子，因为他们遵守同样的量子力学规则。

The polarised photons were able to take the place of the particle and the antiparticle in Dr Hardy's thought experiment because they obey the same quantum-mechanical rules.

极化的光子可以代替哈迪的思想试验中的粒子和反粒子，因为他们遵守同样的量子力学规则。

If a particle/antiparticle pair comes in contact with each other, the two annihilate and produce a burst of energy, which may manifest itself in the form of other particles and antiparticles or electromagnetic radiation.

如果粒子/反粒子彼此相遇，那二个粒子湮灭并且产生能量爆发，可能以其它粒子形式和反粒子或电磁辐射显示它自身。

It has been known for many years that an electron and its antiparticle, the positron, may together form a metastable hydrogen-like atom, known as positronium or Ps ref.

多年前科学家就已经知道，一个电子和它的反粒子，即正电子，能够结合形成一个亚稳态的、像氢原子一样的原子，被称为positronium。

It has been known for many years that an electron and its antiparticle, the positron, may together form a metastable hydrogen-like atom, known as positronium or Ps ref.

多年前科学家就已经知道，1个电子和它的反粒子，即正电子，能够结合形成1个亚稳态的、像氢原子1样的原子，被称为positronium。

But GST= 0.156, Nm=1. 588. As a result, the foundation of Youyongchi Avicennia marina population was the result of the migration of hypocotyles and human factors.

这项工作可以为海岸防护林中新引进种类的判定以及为研究种群建立者效应方法的确定提供科学依据。

The two-dimensional CDRC-ADI-FDTD update equations for collision unmagnetized plasma are induced. The unconditional stability of the CDRC-ADI-FDTD formulation for collision unmagnetized plasma is obtained by the examples.

推导了碰撞非磁化等离子体中的二维CDRC-ADI-FDTD迭代公式，并用算例验证了碰撞非磁化等离子体CDRC-ADI-FDTD算法也是无条件稳定的。
