相对论性

• Together with the rapid progress of relativistic nucleon - nucleon collisions , many phenomenological models were built up and hope that those models can give reasonable explanation of the existed experimental results and give reasonable prediction for the forthcoming experiments
  在相对论性核一核碰撞实验迅速发展的同时，许多唯象理论模型也相继建立，通过模拟计算，以期给实验结果以合理的物理解释，并对将来的实验作出预言。
• Topics include : lorentz transformations , length contraction and time dilation , four vectors , lorentz invariants , relativistic energy and momentum , relativistic kinematics , doppler shift , space - time diagrams , relativity paradoxes , and some concepts of general relativity
  题目包括：洛伦兹变换、长度收缩、以及时间膨胀、四种向量、洛伦兹不变数、相对论性能量与动量、相对论性运动学、多普勒位移、空间-时间图，相对论中的佯谬、和一些广义相对论的概念。
• But if engineers can figure out how to integrate millions of relativistic gates on a small silicon chip ? and awschalom is working with research groups at intel and hewlett - packard to do just that ? the result could be processors that run much faster than current models do , while consuming far less power and radiating far less heat
  不过假如工程师有办法把几百万个相对论性逻辑闸整合在一小块矽晶片上，其成果可能就是执行速度比当今机种快很多，而功率消耗与热辐射却少得多的微处理器；奥沙隆目前正在和英特尔与惠普的研究群合作研发这种晶片。
• Firstly , the propagation of intense laser light in ionizing gases is analyzed including the ionization - modulation instability , the vectorial and nonparaxial effects , and the mechanism of laser energy loss . secondly , we analyze the propagation of intense laser light in plasmas , and effects such as the weakly relativistic nonlinearity , the ponderomotive force and the wakefield are analyzed
  文中对强激光在电离气体中传输的电离不稳定性、矢量非傍轴传输和能量损耗机制，以及强激光在等离子体中传输的弱相对论性非线性效应、有质动力作用和尾波场效应等都作了基本的分析。
• Even if qgp is formed , it can just exist for a very short period of time and then decays into final state hadrons at the end of the expansion and the cooling of the system . the initial state information may be damaged by the final state interactions during the evolution process
  在相对论性核?核碰撞中，即使qgp已形成了，也只是在碰撞过程的极短瞬间存在，随着系统的膨胀与冷却，它很快就演化为实验观测到的各种末态粒子，最初存在的信息也可能在演化过程中由于各种末态相互作用而变得不清晰了。
• The model reproduced the following facts of wa97 experimental data : the yield of strange particles increases with increasing mass and increasing centrality of the colliding system , and also with increasing strangeness content of hyperons in relativis - tic nucleus - nucleus collisions . the simulation of strangeness production using luc1ae model shows that strangeness production is related not only to the rescattering . but also to the collective interaction among strings in relativistic nucleus - nucleus collisions
  Luciae模型能很好地描写wa97发表的单奇异和多奇异重子的产额和横质量分布的实验数据，能较好描写wa97实验所揭示的相对论性核-核碰撞中奇异粒子产额随碰撞体系质量、中心度的增大而增加和奇异粒子增强随奇异粒子所含奇异夸克数的增加而增强的实验事实。
• Abstract : the magnetic moment of a hydrogen atom is calculated by using the solution of the relativistic wave equations . it is shown that the so called total magnetic moment are produced from the electron orbit motion . these results show that the total angular momentum j is actually the relativistic orbital angular momentum
  文摘:利用氢原子的相对论性波动方程解计算了氢原子的磁矩.结果表明，现行量子理论中所谓的总磁矩实际上都是由电子的轨道运动产生的，由此提出了所谓的总角动量实际上是相对论性轨道角动量的看法
• However , the effect of rsf leads to the singularity of beam redius focused to zero with infinity laser intensity when the laser power is lager than a critical value in the absence of other effects . then , we anlyze the effect of higher order relativistic nonlinearity ( hor ) and find that this effect can arrest the singularity due to the effect of rsf
  因此，研究了高阶相对论性非线性效应对激光传输的影响，发现高阶相对论性非线性效应能够抑制这种奇异性的出现；并对高阶相对论性非线性效应与非傍轴效应作了比较，发现高阶相对论性非线性效应起主要作用。
