| 1. | Qcd sum rule and hadron physics 求和规则与强子物理 |
| 2. | Quantum chromodynamics , qcd 量子色动力学 |
| 3. | Chiral symmetry spontaneous breaking and confinement are two very important properties of low energy qcd 手征自发破缺和色禁闭是低能qcd的两个重要性质。 |
| 4. | Qcd sum rule is one of those approaches designed for analytic calculation and suitable for the preceding aim Qcd求和规则是非微扰方法中的一种,可以用来解析计算重子质量。 |
| 5. | With the development of quantum chromodynamics ( qcd ) , people started to investigate the origin and nature of the pomeron from qcd viewpoint 随着量子色动力学( qcd )理论的发展,人们开始用qcd的观点去探讨pomeron本源和性质。 |
| 6. | At finite baryon densities , the underlying theory of strong interaction , qcd , is not solvable in the nonperturbative low - energy regime 而对于有限重子密度,强相互作用的基本理论量子色动力学( qcd )在低能区是不可解的。 |
| 7. | As is well known , in high energy collisions the hadromzation of partons , being a soft process , can not be analyzed using perturbative qcd ( pqcd ) 在高能碰撞多粒子产生中,部分子的强子化是一个软过程,不能用微扰qcd来进行研究 |
| 8. | So it ' s very difficult to study nuclear phenomenon with qcd . while qhd is a low energy effective theory which describes hadronic physics very well 在当前, qhd理论是一个很好的研究中低能区强子物理的有效理论,其物理描述简单,直观。 |
| 9. | Second , the quark potential has to be at present determined phe - nomenologically due to qcd nonperturbation and the mechanism of quark confinement is still in search 尹其次,由于夸克势只能唯象地得到,夸克禁闭机制及其对重介子的影响仍在探索之中 |
| 10. | On the contrary , the fractal in space - time evolution in e + e - collisions turns out to be self - similar , which is due to the isotropy of qcd dynamics 另一方面,在e ~ + e ~ -对撞所产生的末态粒子阶乘矩的分布中呈现出各向同性,表明时空演化中的分形结构为自相似。 |
