密度矩阵 meaning in Chinese
density matrix
Examples
- When the density matrix of the whole ensemble consisted of system - meter is reduced to the microscopic physical system , the system trend quantum decoherence in nature
把由系统与仪器组成的系综的密度矩阵约化到被测系统部分，于是自然趋近量子退相干。 - The model has been generalized to the condition with dissipation , which is an effective work of mine , and the evolution equation of the density operator is present
此外，我的一个有效工作是还把该模型推广到有环境耗散情形，引入系统密度矩阵的演化动力学方程。 - As the representation of the electron spin angular momentum is two - dimensional or three - dimensional , the electron energy is calculated simplier by the theory of density matrix and average value
当电子在磁场中的自旋角动量的表示为二维和三维时，应用密度矩阵原理求解其能量更为简便。 - In chapter 2 , we use an open v - type three - level system model with incoherent pump put forward by yelin , and give a universal nonlinear analytical solution of the steady state by density - matrix equations of motion
第二章中我们使用了yelin等提出的具有非相干泵浦的开放v型三能级系统模型，通过密度矩阵运动方程给出了该系统的定态非线性解析解的普遍表达式。 - ( 3 ) for classification of states , a scheme has been proposed , in which we can translate any three - particle matrix into the special form p3 by random local unitary transform , and make use of this special state p3 to classify quantum state
( 3 )对于量子态的分类问题曾有人提出通过随机局域幺正变换把任意三粒子量子态密度矩阵转化为一种特殊的密度矩阵_ 3的形式，并利用_ 3这一特殊形式对三粒子量子态进行分类。
