In 1990s based on the eigenfunction method of representation theory of groups , a new method , the symmetrized boson representation ( sbr ) method , was brought forward 90年代，陈金全等人在点群的表示理论上提出了一种新的方法，对称化玻色表象方法( sbr ) 。
It examines how atoms of a gas behave at extremely low temperatures , in a theory developed in collaboration with indian physicist satyendra nath bose 这份手稿研究了在超低温情况下气体原子的运动情况，这是爱因斯坦和印度物理学家玻色共同合作提出的有关量子学说的一项重要理论。
The gross - pitaevskii equation governs the evolution of macroscopic wave function . its nonlinear properties owe to the interaction between the bose - einstein condensates " atoms 在玻色-爱因斯坦凝聚中凝聚体的宏观波函数满足非线性的gp方程，它的非线性性质来源于原子间的相互作用。
These novel atom sources are based on bose - einstein condensates ( bec ) from which a coherent matter wave beam is extracted , which have coherence , monochrome and high direction 这种在玻色-爱因斯坦凝聚( bec )的基础上产生的新型激光器，具有和以往的光子激光类似的特征：单色性、相干性和方向性。
Generally , the bose statistical formula will be transformed into integral manner to get the relation between the critical temperature and the particle population in an analytical form 一般研究理想情况下的凝聚是采用将玻色统计公式转化为积分的方法。这种方法可以对bec的临界现象给出一个解析的表述。
Bose - einstein condensation , although more than 70 years old , is bringing to the science fresh air . chapter ii gives the relation between the critical temperature and the particle number through a direct numeric summary 第二章主要用数值求和的方法研究了理想气体玻色-爱因斯坦凝聚转变温度与粒子数的关系。
The flattened multitude of gluons then begins to overlap , falling into the same quantum state , similar to the way atoms in a low - temperature bose - einstein condensate overlap and behave collectively as one gigantic atom 这种重叠的行为类似于低温原子所形成的玻色?爱因斯坦凝聚，其集体表现就有如一个巨大的原子。
This article studies the problem of bose - einstein condensation for the ideal bose gas in external potential field of the arbitrary spatial , thus the heat capacity is calculated and the heat capacity properties is discussed 摘要研究了在任意空间外势场中理想玻色气体的玻色爱因斯坦凝聚问题，从而计算热容量且讨论了热容量性质。
Moreover , we obtain the energy band structure , and the band width of the low - lying energy spectrum of the becs due to the quantum tunneling between degenerate ground states . thus we are able to investigate the coherent properties of the bose - josephson oscillations 此外，我们获得了由于量子隧穿导致的简并基态能级劈裂，计算了低能能谱的带宽，在此基础上讨论了玻色?约瑟夫森振荡的相干特性。
Quantum system is classified as fermi system and bose system according the statistics of its particles . correspondingly for electron and photon transmission we discuss the classical capacities of fermion channels and boson channel in chapter 2 and chapter 3 respectively 量子系统通常根据其粒子的统计性质分为费米系统和玻色系统，在第二、三章我们将分别讨论电子传输的费米信道经典容量和光子传输的玻色信道经典容量。
