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

变过形的脉冲在低强度下显得很敏感，这种强度很小，因此很难进入更高的电子状态。于是，很明显地，这些脉冲能给通过破坏性和建设性的干扰效应来操控异构化作用。观测到的振动一致信号更支持了这样一种机制。

First, the coherence of the hard determinist's position is controversial.

第一，强决定论者的立场的融贯，是有争议的。

A new kind of standard detonator was designed to ensure the coherence of testing results.

Study of temporal and spatial coherence of light emitting diode.

发光二极管的时间与空间相干性研究。

The dynamic coherence analysis based on multivariate autoregressive modeling was applied in the observation of synchronization between brain areas during cognitive processing.The result indicates that the synchronization of relative brain areas happens automatically despite the distractive stimulus during object perceiving,but the disturbed attention affects the synchronization of those areas involved in the judgement and voluntary movement as the way it affects the reaction time.

基于多变量自回归模型的动态相干性分析方法，被用于观察不同脑区在认知过程中的同步化，结果显示，人在感知和识别物体时，相关的脑区自动地发生了同步化的神经活动，这种同步化被证实是不受干扰刺激影响的，但被干扰的注意力确实影响了与判断和主动运动有关的脑区的同步化，而且这种影响的趋势与反应时间的分析结果一致。

In chapter 4, for the first time, we studied the control role of the relative phase between the probe and driving fields on inversionless gain of the probe field in a closed and Doppler broadeningΛ-type three-level system with the spontaneously generated coherence.

结果发现：(1)不管探测场和驱动场是同向传播还是反向传播，驱动场是失谐还是共振，无反转增益总是随相对位相的改变而作周期性变化，周期为2π。
