It is found that:(1) the variation of dFM may lead to two different features for the IEC,one is the oscillatory behavior of IEC with the spacer thickness,the other is the exponential behavior in the most spacer thickness.(2)As a oscillatory function of dFM ,the IEC exhibits multiple periods and a negative non-oscillatory term.(3)The Fermi energy of the conduction electrons has a little variation as the magnetization of the two FMs changes from parallel to antiparallel alignment,furthermore,this variation is correlated with the IEC to some extent.

结果发现：（1）dFM的变化会导致层间交换耦合出现两种不同的特征，一种是随着中间层厚度的增加，IEC有振荡行为；另一种是其指数衰减行为；（2）作为dFM的振荡函数，IEC表现出多个周期和一个负的非振荡项；（3）传导电子的费密能会随着两铁磁体的磁化排列变化而稍有变化，进一步地，这种变化与IEC有着某种程度的关联。

Within an hour, the fervour of the two speakers, and the intellectual passion surging through the crowd, set off an angry antiphonal exchange between the two proponents of totally different philosophies of mathematics.

The main idea is to design two CNNs with two antithetic CA rules.By this way,Image restoration can be implemented,getting obviously better results than the traditional ones.

核心思想是用两个对偶CA规则设计两个CNN网络，联合实现图像滤波处理，能够获得比传统算法好得多的处理速度和效果。

We find in form, the surface parts which are put in front of the time marks of the two structures are antithetic of affirmation and negation; in content, these two structures fully show their complementary distributions with their process meaning and critical meaning. And the essence of the complementary distributions is the contradiction of one-way dimension of objective time and inverse subjective thought.

从形式上看，在"没有VP之前"与"VP之前"结构的时间标记之前的表层成分是否定和肯定的对立；从内容上看，尽显"没有VP之前"与"VP之前"各自独立品格的是过程意义与临界意义的互补分布。

Two-thirds of the way through the movement, there is the heart-stopping moment where two notes, separated by the length of the piano, hang suspended. Barenboim seemed to hold them for an eternity as if emphasising this metaphor of apartness in life, the apparent impossibility of resolution.

在该乐章的三分之二处，有一个令人屏息的瞬间：两个在键盘上隔了很远的琴键被按下，并悬置在那里，巴伦博伊姆似乎把它们按下了无限久的时间，像是要突出对人生聚少离多、解决难求的隐喻。

Moreover, the synchronization of EAN is studied; the result shows that the stochastic networks are more poorly synchronized than their deterministic counterparts. These models can well mimic some real systems. Firstly, two dimensional random Apollonian networks and two dimensional EAN are maximal planar graphs, which may be helpful for designing printed circuits. Secondly, V-HDRAN can be mapped into the Yule process, which was inspired by observations of the statistics of biological taxa. From this perspective, V-HDRAN can find some applications in biological systems. Thirdly, all networks of this type consist of complete graphs; this particularity of the composing units can provide a comprehensive aspect to understand some real-life systems making up of complete graphs, such as movie actor collaboration networks, scientific collaboration networks and networks of company directors.

这些模型可以很好地描述现实系统，其中二维随机阿波罗网络与二维演化的阿波罗网络为最大平面图，这对印刷电路板等现实系统的设计有重要的借鉴作用；变体模型V-HDRAN的构建过程与Nature上发表的关于生物物种的形成过程之间存在一个一一对应的关系，这对生物系统的建模有重要的价值；另外，这类网络均由完全图组成，它们对由完全图组成的电影演员合作网、科学家合作网、公司董事网等由完全图构成的现实网络的建模有重要的理论意义和应用价值。
