物质粒子

In the theoretical framework of the relativistic mean field, the influences of π- meson condensate on the equation of state and the particle fractions of neutron star matter including delta isobars are studied.

在相对论平均场理论框架下研究了π-介子凝聚对包括Δ共振态的中子星物质状态方程及其粒子分布的影响。

For the first time, we studied isospin effects on the two particle correlation functions, the light particle multiplicity and their ratio in HIC''s at intermediate energies, and find they are sensitive probes for the density dependence of the symmetry energy.

在国际上首次研究了重离子碰撞中两核子关联函数和轻粒子产生的多重性及比率的同位旋效应，发现它们敏感于核物质对称能的密度相关性。

"In the early 1970s it was discovered that these particles are made up of several types of even more basic units, named quarks, which, together with several types of leptons, constitute the fundamental building blocks of all matter."

1970年代初，发现这些粒子由几类称为夸克的更基本的单元组成。夸克与几类轻子一起组成了所有物质的基本结构单位。

"In the early 1970s it was discovered that these particle s are made up of several types of even more basic units, named quarks, which, together with several types of leptons, constitute the fundamental building blocks of all matter."

Researchers believe that when the two beams smash together for a combined 14 TeV, never-before-seen particles may pop out, such as the long-sought Higgs boson, thought to be the source of matter s mass.

研究者相信，当两束总能量达到14 TeV的粒子束对撞的时候，从未见过的粒子可能将出现，比如追寻了很久的希格斯玻色子，它被认为是物质质量的来源。

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。

" Colloid : Substance consisting of particles that, although too tiny to be seen with the unaided eye (typically 1 nanometre to 10 micrometres), are substantially larger than atoms and ordinary molecule s and that are dispersed in a continuous phase."

胶体：由比原子或普通分子大得多，但远小于肉眼可见的微粒组成的物质。这种粒子的大小大约在10-7～10-3公分，并且以各种方式连接或键合在一起。

Similarly, an experiment carried out in Long Island a few years ago, which was intended to produce a form of matter known as strange quarks, caused a few imaginative worrywarts to fear that the entire planet would be converted into subatomic particles called strangelets.

同样地，几年前在长岛进行了一次实验，旨在制造一些名为&奇夸克&的物质形态。这次实验也引起了一些杞人忧天的恐惧，害怕实验会将整个地球变成一种名为&奇异滴&的亚原子粒子。

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。
