Meson: Any member of a family of subatomic particles compose d of a quark and an antiquark.

介子：由一个夸克和一个反夸克组成的亚原子粒子族。

A B meson is a short-lived particle made up of both matter and antimatter -- one quark and one antiquark.

B介子是一种由物质和反物质组成的短寿命粒子。

The CDF physicists measured the rate of matter-antimatter transitions for the neutral Bs meson, a particle composed of a "bottom" quark and a "strange" antiquark.

CDF的物理学家们测量了中性Bs介子（一种由一个底夸克和一个奇夸克构成的粒子）的物质-反物质转变速率。

Further works are clearly needed to develop the model to reach a better understanding of the heavy meson properties, and to extendinvestigation of baryon properties.

进一步的工作需要考虑模型本身的完善来达到对重介子性质的更好理解，并将这个势扩展到对重子性质的研究。

The wave functions describing meson and baryon are composed of orbital, color, spin and flavor.

在放热反应的阈能处，入射粒子的相对动量为零，截面趋于无穷大。

In the ω meson propagator there are two k〓k〓 terms, the longitudinal term is unrenormalizable, so it is difficult to take account of it when the baryon current conservation is violated.

矢量介子传播子中含有两个k〓k〓项，其中纵向项是不可重整化的，因此在流守恒被破坏时完全顾及这项的贡献是有困难的。

We have further studied the contribution of the k〓k〓 terms to the baryon and meson spectral functions and their influence on the effects of self-consistency by means of the rule we suggested.

在不考虑k〓k〓项的贡献时，我们给出了保证重子谱函数不出现负值的耦合参数范围，同时初步考察了k〓k〓项对重子谱函数的影响。

Though unstable, many meson s last a few billionths of a second, long enough to be observed with particle detectors.

介子虽然不稳定，许多介子只存在10亿分之几秒，但用粒子探测器已足以观察到它们。

Bosons include meson s, nuclei of even mass number, and the particles required to embody the fields of quantum field theory.

玻色子包括介子、偶质量数的原子核以及体现量子场论中的场所需要的粒子。

His female bullfighter Lydia gradually Health love, but she was in a vegetative state after the Bulls Zhuangcheng away from her, just because Lydia's ex-boyfriend showed more affectionate than he is like love.

他对女斗牛士莉迪亚渐生爱意，却在她被公牛撞成植物人后离她而去，仅仅因为莉迪亚的前男友表现出好似比他更深情的爱。

I know of none which are not easy to answer, but what I am trying to do now is only by a series of hints to throw some light on the narrow path of legal doctrine, and upon two pitfalls which, as it seems to me, lie perilously near to it.

我不认为有什么难以回答的问题，但我现在要做的仅仅是通过一系列线索，来给法律理论的狭窄路径以及在我看来离它近得危险的两个陷阱提供一些启示。
