由动量空间计算得到的夸克和反夸克之间的散射振幅推导坐标空间等效势时，总要出现算符排序问题，这是一个量子力学中长期存在而又未能得到很好解决的重要问题。

We obtain a new quark potential from the effective dilaton-gluon-coupling inspired by superstring theory, and by using this static potential, we explore the mechanism of quark confinement through calculations of the spin-average energy levels, the widths of the leptonic decays and radiative transitions for heavy quarkonium. The obtained results are compared with that of the Cornell potenial.

由规范场理论的超弦理论所激发的伸缩子一胶子有效藕合，给出了一个新的静态夸克一反夸克势，讨论了此势模型下重介子的自旋平均能谱、轻子衰变和辐射跃迁宽度，并与Cdrn叭势模型所得到的相应结果作了比较。

In order to study the transitions between quarks, we integrate out the effective antiquark fields and get a form of effective Lagrangian in terms of effective quark fields.

为方便描述正夸克间的跃迁过程，将上一步得到的有效拉氏量中有效反夸克场积分出去，从而在拉氏量中仅明显包含有效正夸克场。

For the system such as NN,π〓π〓 in which there are not quark and antiquark with the same flavor, only t-channel OGEP is needed to consider; but for the system such as K〓 in which a quark and an antiquark may have the same flavor, the effect of q〓 annihilation must be taken into account.

对于不含有相同味道夸克—反夸克的相互作用体系如NN，π〓π〓，显然是合理的；但对于类似πN，K〓这类含有相同味道夸克—反夸克的体系，湮灭道的贡献必须考虑。

原有重夸克有效理论的出发点是在重夸克质量m〓很大的条件下夸克与反夸克场几乎无耦合。

The problem is how to consider the relativistic corrections to this potential. Adopting the assummation that the quark interaction is the sum of the usual one-gluon direct exchange and the mixture of linear scalar and vector potentials, we structure the relativistic corrections of order v2/c2to the Cornell potential, including the annihilation potential for the quark and antiquark of the same favors which plays the same role with the one-gluon direct exchange at short distances.

采纳库仑势源于单胶子直接交换，而线性禁闭源于标量和矢量的混合，同时考虑在短程区域与单胶子直接交换起同样作用的同味正反夸克的湮灭，构造了静态夸克-反夸克势到v~2／c~2级次的完全相对论修正，并拟合计算了重介子偶素的能谱，讨论了相对论修正对重介子偶素能级分裂的作用。

Integrating out the small parts of the quark and antiquark fields but keeping both the quark and antiquark freedom in QCD, we get an effective Lagrangian which contains quark, antiquark and quark-antiquark mixing terms.

从QCD拉氏量出发，同时保留其中正，反夸克自由度贡献，仅将正，反夸克场中的小分量积分出去而得到一个包含正夸克项，反夸克项及正反夸克耦合项的拉氏量。

The findings suggest that dark matter particles interacted so that they "annihilated" each other, producing subatomic particles called quarks and their antimatter counterparts, antiquarks.

这些发现表明，暗物质粒子之间发生互相作用，互相&残杀&，结果产生了叫做夸克的亚原子粒子以及它们的反物质粒子——反夸克。

The transformation between I3F,C3F,t3F and YF of three generation quarks and leptons of Fermi type follows the hypercharge-spinor transformation,and so does that between I′3B,C′3B,t′3B and Y′B of their three generation supersymmetry companion s,antiquarks and antileptons of Bose type.

三代费米型夸克、轻子的I3F，C3F，t3F，YF间及它们的超对称伴子三代玻色型反夸克、反轻子的I′3B，C′3B，t′3B，Y′B间均满足超荷-旋量变换。

But because difference among the predictions of different theoritical models in low z region is small, it is hard to tell us which model is more compatible with the experimental result. Our results from high z binning show a good consistence with the predictions based on z-dependence SU (3) asymmetry, quark-Diquark and pQCD model, which indicate the ud quarks in Λ hyperons provide contributions as well as s quark and the contribution is the function of z.

高z区间分法下归一法和螺旋度平衡法的分析结果显示同z依赖的SU（3）对称模型、夸克--反夸克模型和pQCD模型预言的纵向自旋转移值S〓和z的关系较一致，从而表明Λ超子中u夸克不但对Λ的极化有贡献，而且其贡献和Λ携带的能量份额z有关系。
