| 1. | A search for magnetic monopoles has been going on ever since dirac . 从狄拉克以来,对磁单极子的探索却一直没有停止。 |
| 2. | Dirac ' s equation containing two intrinsic spins 包含两个内禀自旋的狄拉克方程 |
| 3. | Fermi - dirac statistics 狄拉克统计 |
| 4. | In chapter 1 we introduce the driac equation following the physically motivated approach of dirac 第一章我们介绍基于狄拉克之自然逼近的狄拉克方程。 |
| 5. | Supersymmetry and eigen energy spectrum of a charged dirac particle in a uniform constant magnetic field 均匀恒定磁场中带电狄拉克粒子的超对称性和本征能谱 |
| 6. | The hamiltonian of the system is the driac operator which as a matrix differential operator is not semibounded from below 系统的哈密顿函数是作为矩阵微分算子的狄拉克算子,它不是半有界的。 |
| 7. | Midway up the slope , however , i staggered to a halt , gasping in the rarefied air , well before i reached the heights where the equations of einstein and dirac would have made sense 可惜才到半山腰,便开始步履踉跄;空气稀薄,使我气喘吁吁,不得不停下脚步,而爱因斯坦和狄拉克的方程式却仍旧远在高处。 |
| 8. | Midway up the slope , however , i staggered to a halt , gasping in the rarefied air , well before i reached the heights where the equations of einstein and dirac would have made sense 登到山坡的一半时,我摇摇晃晃的停下来,呼吸稀薄的空气,这时,距离我能够理解爱因斯坦或狄拉克的方程式的高度还相差很远。 |
| 9. | A class of exact solutions of the dirac equation are obtained for an electron in the electromagnetic field of a wave guide formed by two pairs of hyperbolic cylinders 摘要研究了位于由两对双曲柱面构成的波导管电磁场里的单电子的性质,得到了单电子在场中狄拉克方程的新一类精确解;计算了极化算符的本征函数。 |
| 10. | In the second quantized theory , however , the negative energies lead to the prediction of antiparticles ( positrons ) which is regarded as one of the greatest successes of the driac equation ( chapter 10 ) 然而,在二次量子化中,负能量导致了存在反粒子(正电子)的预言而被看作狄拉克方程的最伟大成就之一(第10章) 。 |
