reduced density meaning in English
对比密度
折算密度
Examples
- Xrays of limb bones may show reduced density and thin cortices and in some cases fractures in metaphyses
对四肢骨骼的x光检测显示出骨量减少，皮质变薄，甚至干骺端碎裂。 - Their results of n , 1 and l are the same to ours only when the reduced density is less than 10 - 3
由于他们采用了低密度近似，他们所得的g们，久只在约化密度尸”小于10 ’时才与我们的数值结果一致。 - This dissertation proves that formation of entanglement is smaller than mutual information . as a by - product , this dissertation also proves that there does not exist this kind of quantum state whose nearest separable state is the product of its two reduced density matrices except the state whose classical correlation is zero
证明了结构纠缠小于互信息，同时证明了对于任意的量子态(除了经典关联为0的态) ，它的两个约化密度矩阵的直积不可能为它的最近分离态。 - With the hamilto - nian of the interaction between the field and the atom with an intensity - dependent coupling , the evolution operator and the reduced density operators of the field and the atom are derived without taking the influence of the environment into account , then the basic work model without dissipation is established
从光场与原子依赖强度耦合相互作用的哈密顿量，推出了无环境影响的依赖强度耦合j - c模型中系统的一般时间演化算符和光场与原子的约化密度算符，建立了研究不考虑环境影响的j - c模型的一般动力学的基础。 - We deduce easily the coherent term of quantum dynamical model ( the off - diagonal of reduced density matrix ) by improving the nature of displace operator and the nature of coherent states . then , the interaction is energies of a two - photon mechanism and the usual one - photon or liner driving mechanism . we deduce the coherent term by improving the nature of squeezing operators , displace operators and canonical transformation
其一，仅有阻尼相互作用和势能相互作用，此时利用位移算符的性质和相干态的性质很方便地推导了量子动力学模型的相干项(约化密度矩阵的非对角元) ；其二，考虑的是既有单光子相互作用又有双光子相互作用，这时利用相干态、压缩算符及正则变换等的性质推导出相干项。
