查询词典 hadrons

Thus, it is very important to carry out the research in understanding theessence of vacuum such as vacuum condensate. On the level of quarks, using the non-perturbativeQCD method to investigate the structure of hadrons under strong interaction and to develop nu-clear physics are the key research projects in current nuclear physics frontier.

故而，真空凝聚等有关真空本性的研究具有重要意义，从夸克层次和非微扰色动力学的途径研究强子结构、强相互作用，发展核物理，是当前核物理研究的前沿基本课题。

In high energy heavy ion collisions, the suppression of the yield of final state high transverse momentum hadrons is considered to be a important signal of exiting Quark-Gluon Plasma. In the process of Nucleus-Nucleus collisions, hard scattering is on the initial stage.

这种相变的发生是由于以相对论速度飞行的高能重离子在相互发生碰撞的过程中，巨大的粒子动能被沉积在核-核碰撞的有限区域内，并转化为热能，形成极端高温高密环境，迫使强子体系解禁闭，形成QGP新物质形态，并最终转化为末态粒子的产生。

This thesis mainly concentrates on the the hadrons which are recently discovered by the BES Collaboration and the Babar Collaboration, mostly we use phenomenological models of hadron structure to estimate the hadron mass, to study the production properties and decay properties and so on.

进一步我们指出X(1835)在γ(1S)→γX(1835)和J／ψ→ωX(1835)中的产生率很小，因而很难被观测到，这样很自然地解释了为什么CLEO合作组在γ(1S)的辐射衰变中没有观测到X(1835)。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
