The comparison experiment results for measuring the displacement with the Abbe apparatus were given in this paper.

测试系统的光路包括四光束双焦点差动式光路和双光束双焦点参考光式光路。

In his embedded-processes model of WM, Cowan (1999, 2001) uses the term focus of attention to refer to the core component of WM, and proposes that the focus of attention of WM and that of perception have the same span, which is a fixed number.

在嵌入加工模型中，Cowan (1999， 2001)将工作记忆的核心结构称为"注意焦点"，并假设工作记忆的注意焦点与知觉的注意焦点的容量限制是同一固定的数量。

Generally, instrumental rumination helped to reduce negative mood, emotional-focused rumination worsened negative mood, and meaning-searching rumination increased the duration of negative mood. Moreover, in the period of severely and long-term negative mood status, instrumental rumination seemed to maintain the duration of positive mood, emotional-focused rumination still worsened negative mood, and meaning-searching rumination seemed to prolong the duration of negative mood. Besides, in the period of negative mood episode, instrumental ruminative had no effect on mood fluctuation, emotional-focused rumination deteriorated and extended negative mood, and meaning-searching rumination had harmful effect on the negative mood but still had borderline effect on the positive mood.

整体平均来说，功用性反刍有助於负向情绪的缓解、情绪焦点反刍会增强负向情绪感受、意义寻找反刍则是增加负向情绪维持的时间；若当天处在长期又严重情绪不佳日子中时，功用性反刍似有维持正向情绪的效用、情绪焦点反刍则是恶化当天的负向情绪强度、意义寻找反刍则有延长当天负向情绪时间的趋势；若连续处在长期且严重情绪不佳的日子中，功用性反刍对情绪变化并无影响、情绪焦点反刍则是延长且恶化此时期的负向情绪状态、而意义寻找反刍不但会影响负向情绪的状态，似也会有助於此时期的正向情绪状态。

In the region upstream of vortex breakdown, the sectional streamlines emanating from the leading edge spiral inward to primary vortex and in the region downstream of the breakdown, on the other hand, the streamlines separating from the leading edge are not entrained into the vortex core in the instantaneous sense. Along the axis, the topology of the primary vortex alters several times starting from stable focus near the apex to unstable focus, and lasts back to stable focus near wake edge, the stable hmit cycle and unstable limit cycle are shown in this evolution.

发现在截面流线谱中，即使奇点的类型、数目及位置相同，奇点的连接方式也有可能不同；旋涡破裂点前，主涡由来自前缘的力线卷绕而成，主涡焦点与前缘半鞍点相连，旋涡破裂后，来自前缘的力线不再卷入主涡，主涡焦点与对称面上的鞍点相连：在流体由翼尖流向后缘的过程中，截面流线谱的拓扑结构发生了多次变化，主涡焦点相继由稳定状态转变为不稳定状态，最后又转化为稳定状态，并先后出现了稳定的极限环及不稳定极限环。

Thus, Chinese is a kind of languages structuring the information focus to some extent from a typological view.

汉语的语序要适应焦点结构要求——信息焦点成分一般不能出现在动词之前，只允许其出现在动词之后，因此，汉语在某种程度上是将信息焦点结构化的语言。

Regarding the durational analysis of focus words and stressed syllables in focus words, native speakers elongate the duration of focus words in both statements and questions in any position.

至於在焦点字和焦点字中的重音音节的音长分析中，美国人在肯定句和疑问句及任何位置中都会拉长焦点字的音长。

And local dark focal spots may be obtained, the focal spot may evolve into a circle, a two-peak spot, or a curve line, which indicates that the combination of nonspiral and spiral phase plates can be used to form novel focal spots.

随着相位片参数变化，焦斑可演化成环形焦斑、具有两个光强峰值的焦斑、或是曲线形焦斑，这些现象说明可以将螺旋和非螺旋两种相位片结合用来调节焦点光强分布，得到新型焦斑。标签相位片焦点移动焦点破裂光陷阱

Both kinds of rats were inbred to construct the new inbred strains from Sprague-Dawley outbred strain background. In the first section, conventional visual electrophysiology was observed in CSNB and RCD rat.

在课题的第一部分，我们对这两种动物的视觉电生理性状进行了观察，包括：常规视觉电生理，CSNB大鼠的暗适应多焦点视网膜电图和明适应多焦点视网膜电图，RCD大鼠的不同颜色刺激光暗适应多焦点视网膜电图。

In his embedded-processes model of WM, Cowan (1999, 2001) uses the term focus of attention to refer to the core component of WM, and proposes that the focus of attention of WM and that of perception have the same span, which is a fixed number.

在嵌入加工模型中，Cowan (1999， 2001)将工作记忆的核心结构称为&注意焦点&，并假设工作记忆的注意焦点与知觉的注意焦点的容量限制是同一固定的数量。

Low-light performance is good even without the use of focus assist lamps, and the E-300 will fire a burst from its internal flash, if raised, or turn on the focus assist lamp of an attached FL-36 flash to achieve precise focus even in complete darkness.

低光绩效没有焦点帮助灯的使用甚至很好，而且电子 300 将会点火来自它的内部闪光的一个爆炸，如果升起，或打开焦点协助一个附上的 FL-36 闪光的灯甚至在完全黑暗方面达成精密的焦点。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
