查询词典 coherence

The coherence and constructive interference with a widely-separated doublet viacollision-aided radiative excitation in an open four-level system is studied with thedensity matrix approach for the first time.

The shaped pulses were shown to be phase-sensitive at intensities too low to access different higher electronic states, and so these pulses apparently steer the isomerization through constructive and destructive interference effects, a mechanism supported by observed signatures of vibrational coherence.

脉冲形状被证明是在太低以至于不能进入不同的较高电子态的强度上对相位变化灵敏的，因此这些脉冲机制通过构成和破坏干扰反应操纵着异构化作用，这种机制由观测到的相干信号支持。

Under the guidance of city planning, the spatial contexture of the streets should continue the historical unity and coherence in writing and show the traditional structure and also solute contradiction appropriately between the modernizational constructions and inheriting traditions.

For most of my audio life I have lived with large planar speakers, convinced that no dynamic design could offer the coherence and continuousness of panels.

试译：由于曾确信动圈设计的音箱无法提供平面设计的一致性和连续性，因而我的音响生涯中的大部分时间都是与大型平面音箱一起度过的。

By matrix conversion and coordinate transform, the part surface measured data can be converted into assembly model, therefore, the characteristic of part surface coherence and boundary share will be assured.

本文提出了一种基于基准点和配合轮廓的装配建模方法并在实践中应用，使摩托车配合件达到了共线的设计要求。

It is claimed that discourse coherence enjoys in nature the dichotomy between overtness and covertness, objectivity and subjectivity, determinacy and indeterminacy.

文章在分析了连贯的二元性特征的基础上，试图从语言形式、语用环境和认知心理三个方面来建立连贯的三个阐释标准。

The axial length, refraction power of cornea（K1 and K2）and anterior chamber depthwere determined by optic coherence biometryafter cycloplegia.

3 12岁近视儿童79例140眼经门诊睫状肌麻痹后检影验光，采用光学相干生物测量仪测量其眼轴长度、角膜屈光力（K1、K2）、前房深度，计算眼轴长度与角膜曲率的比值AL/CR，对测量值进行统计分析。

The baseline examination included visual acuity, subjective refraction, Maddox Wing test (Clement Clarke International Ltd, Harlow, UK), partial coherence interferometry, slit lamp examination, automated refraction in cycloplegia, an oral questionnaire, and a cycle ergometer test.

基本检查包括视力、主观验光、马多克斯翼检查（英国Harlow Clement Clarke国际公司）、部分相干干涉测量法、裂隙灯检查、睫状肌麻痹后自动验光、一份口头调查问卷以及蹬车运动试验。

The results show that for weak driving, the population difference displays damping coherent oscillation and/or damping quantum beat, depending on the initial preparation. The coherence exhibits damped oscillation with Rabi frequency.
