反粒子

The antiparticle of the π°is indistinguishable from the π°.

介子的反粒子同π°本身是无法区分的。

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。

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。

It is in no sense a provisional theory and is largely compatible with quantum theory; it not only led to the idea of matter waves but is the origin of 'spin' and underlies the existence of the antiparticles.

这是没有意义的理论和临时主要是与量子理论兼容，它不仅导致了物质波的想法，但就是'原产地旋转'和基础的反粒子的存在。

As a consequence, the contributions of antiparticles are very small under our consideration.

还研究了反粒子的贡献，他们确实很小。

Paul Dirac's theory has been experimentally verified and today a wide range of antiparticles have been detected.

保罗·迪拉克理论已经得到实验验证，而且今天大范围的反粒子已经被发现。

Otherwise, antiparticles only arise due to extreme events such as nuclear reactions or cosmic rays from dying stars .

否则，只会产生反粒子，由于宇宙射线的极端事件，如核反应或死亡的恒星。

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。

核心提示：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。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
