色禁闭
- 网络color confinement;color confinment

正是由于色禁闭这一特征,我们在实验室中无法直接观测到单个的夸克和胶子,仅仅观测到的是夸克和胶子所形成的末态强子。
Because of the color confinement ( or quark confinement ), we can not directly observe individual quark or gluon except the final state of hadrons formed by quarks and gluons in the laboratory .

到目前为止,在夸克层次上能够成功描述夸克间强相互作用理论的是量子色动力学QcD,在这个理论中有两个十分重要的特征:分别是渐近自由与色禁闭。
So far , Quantum chromo-dynamics ( QCD ) is the most successful theory which describes strong interactions between quarks . In this theory , there are two very important characteristics : asymptotic freedom and color confinement ( or quark confinement ) .

手征对称自发破缺和色禁闭是低能QCD的两个十分重要的性质。
In the low energy region , QCD has two very important proper-ties : chiral symmetry spontaneous breaking and confinement , which are closely related to the vacuum characteristics of QCD .

QCD有一个具有非微扰夸克和胶子凝聚的非平凡真空,众所周知,在低能区域,QCD有两个非常重要的特征:手征自发破缺和色禁闭。
QCD has a non-trivial vacuum with non-perturbation condensates of quarks and gluons . As all known , in the low energy region , QCD has two very important properties : chiral symmetry spontaneous breaking and confinement .

通过高能重离子碰撞发现夸克胶子等离子体这一新物质形态有助于我们更好地理解量子色动力学的禁闭特性。
Study of high-energy heavy-ion collisions found quark-gluon plasma of this new material forms will help us better understand confinement , a crucial feature of QCD .

利用从格点规范理论计算得出的,包括色屏蔽效应的禁闭位势;研究了重子结构,计算了重子谱及相应状态下的夸克分布的均方根半径。
A confinement potential which obtained from the lattice-gauge-theory has been used to study the spectrum of baryon and the rms of the quark distribution .

计算结果显示,当强子物质的密度足够高,以致强子互相重叠、抗色介质不再存在时,夸克/色荷禁闭即可解除。
When the density of hadrons matter is so enough high that hadrons are overlap each other and therefore the anti_ color medium no longer exists , the color_charge / quark_confinement can be removed at once .

因此,只有镜像点自由电荷系列线才能实现电荷禁闭,只有在强子外面存在作为抗色介质的(量子)真空区才能实现色电场的夸克/色荷禁闭。
Therefore no other than mirror line of arranged free point charge out of confined region enables to realize charge_confinement and quantum vacuum region as an anti_ color medium out of hadrons enables to realize color_charge / quark_confinement .
