| 1. | A quark ( or an antiquark ) from the projectile hadron radiates a virtual photon on impact on the target , the photon subsequently decays into a lepton pair
入射强子中的一个夸克(或反夸克)在靶的作用下辐射出一个虚光子，虚光子再衰变成正反轻子对。 |
| 2. | In order to study the dynamical fluctuations inside the gluon jets and quark jets , the improved angular rule is proposed to identify these tv / o kinds of jets from the 3 - jet events
为了进一步研究3 -喷注事件中的夸克(反夸克)喷注和胶子喷注内部的动力学起伏的性质 |
| 3. | First , the cornell potential is used widely as phenomenological potentail and takes rather success in explaining the heavy quarkonium properties . the problem is how to consider the relativistic corrections to this potential
如何考虑这个静态势的相对论修正，核心的问题是如何处理夸克-反夸克相互作用的洛仑兹结构。 |
| 4. | The nuclei and their constituent protons and neutrons literally melt , and many more quarks , antiquarks ( antimatter opposites of the quarks ) and gluons are created from all the energy available
在此原子核与其组成的质子与中子真的就融化了，而从所有可用的能量之中，创生出更多的夸克、反夸克（夸克的反物质）与胶子。 |
| 5. | In this region it is necessary to account for nonperturbative effects connected with the complicated structure of qcd vacuum . all this leads to a theoretical uncertainty in the qq po tential at intermediate and large distances
随着重夸克偶素基态和激发态质量实验数据的大量积累，通过理论预期与实验数据的比较，所获得的夸克?反夸克相互作用势的信息是很有趣的。 |
| 6. | The operation and first collisions of au nuclei in the relativistic heavy ion collider ( rhic ) at brookhaven national laboratory ( bnl ) during year 2000 began a new era in the study of nuclear matter at high energy density and the search of quark - gluon plasma ( qgp )
原子核又是由核子通过强相互作用而结合在一起的。强相互作用的基本理论，量子色动力学( qcd ) ，指出所有参与强相互作用的基本粒子都是夸克( q )及反夸克( ( ? ) )的束缚态。 |
| 7. | So cross section and particle production are not calculated consistently . and it is difficult for gri5ov - regge theory to include hard process . the parton 6ased gri6ov - regge theory provide a solution : elementary scatterings happen in parajlel , described phenomenologically as pomeron exchanges
因此，在nexus中pomeron的色弦形成方式就与其它模型很不相同；即使只有一个pomeron交换，色弦的端点也是海夸克和反夸克，而不是价夸克。 |
| 8. | The invariant mass spectrum of dimuons can be used to examine the suppression of j / production . j / w consists of quark and anti - quark . its size is small enough that perturbative theory is meaningful and is not small enough that non - perturbative effect can be completely ignored
它由夸克和反夸克组成，它的尺寸足够小从而微扰理论有意义，但是j的尺寸又没有小到非微扰效应完全可以忽略的程度，因此j介于微扰的夸克和胶子以及非微扰的强子之间。 |
| 9. | The hard process is included in a natural way , which offers the opportunity to calculate the parton spectra and parton density which aie closely related to the forinatioi1 of quark gluon plasma . the strict calculation is performed on the parton level , however , hadrons are finally observable particles
而pomeron与remnant之间的关联，以及pomeron之间的关联，则通过补偿夸克(或感应夸克)来实现? ?每当一个海夸克或一个反夸克从真空中激发出来作为pomeron的色弦端点时，它的反粒子也从真空中激发出来，进入到相邻的remnant中。 |
| 10. | By comparing theoretical predictions with experimental data , one can obtain a valuable information on the form of the qq interaction potential . such information is of great practical interest , since at present it is not possible to obtain the quark - antiquark ( qq ) potential in the whole range of distances from the first principles of qcd
夸克势模型是其中重要的模型之一，它不仅能研究强子的基态，而且能研究激发态，但是，源于在中和大距离与qcd真空的复杂结构有关的非微扰特征，还不可能获得整个距离范围内的夸克?反夸克相互作用势。 |
