For a monotone twist map the well-known Birkhoff fixed point theoremsays that the circles with rational rotation number will break up whence a finitenumber of pairs of periodic points arise,half of which are elliptic and the othershyperbolic.Moreover,around each elliptic periodic point a few of new invariantcurves will appear and make a picture of phase space with a self-similar structure.Again one may ask is there a similar picture for higher dimensional Hamiltoniansystems?
对于单调扭转映射，著名的Birkhoff不动点定理指出，在通有情况下旋转数为有理数的不变曲线一般会破裂，在原来的不变曲线附近会产生有限多对周期点，其中一半是双曲的，一半是椭圆的，而在椭圆型周期点的周围又会产生一圈圈的不变曲线，使得椭圆周期点附近的动力学行为和整个相空间的动力学行为十分相象，换句话说，整个相空间具有无限嵌套的自相似结构，自然又产生了一个问题：对于自由度数目大于2的高维哈密顿系统，其相空间是否有类似的图象？

Simulation shows that the proposed algorithm can achieve similar performance to that of the ITS using natural binary bit mapping and has about 1dB gap with the ITS using Gray bit mapping. In the high SNR region, the complexity of the proposed bit-level ITS is about 6％~40％ of the symbol-level ITS.
仿真结果表明：在误码率性能上，该算法略次于使用自然二进制映射的基于符号的ITS算法，与使用格雷映射的基于符号的ITS算法只有1dB左右的差距；而该算法的计算量在高信噪比时只相当于基于符号的ITS算法的6％~40％。

Thirdly,we define a equivalence relation Rin the topology space X by the fibrewise function f ,and then we get the fibrewise quotient space X / R,we call it the fibrewise decomposition space of X .And last we discuss the relation between f and the natural mapping.
其三是，通过一个纤维映射f ： X→Y，在B上的纤维拓扑空间X中定义了一个等价关系R，得到X的纤维商空间X / R，称其为X的分解空间，最后也讨论了f与自然投射的关系。

First of all, Chinese unique geographical surroundings result in cultivation civilization, in which people's living and production were utterly influenced or even controlled by sun and such disasters as floods and droughts caused by sun made our ancestors much more dread and hate the moon. On the contrary, in the view of our ancestors, moon not only is beneficial to the growth of crops, but brings about brightness, coolness and enjoyment, which in turn makes moon much more popular than sun. As a carrier of national emotion, mythology also contributes to the development of "valuing moon above sun"in that the collective unconscious of hating sun but loving moon reflected in mythologies such as "Hou Yi Shot the suns"and "Chang E's fly to moon"easily finds its expression in the course of selecting poetic images. Philosophically,"masculine"and "feminine"are realized in many aspects of social life, but the trinity of sun, monarchy and father, which is identical with "masculine"dominates the political and ethical field while the trinity of moon, mother and daughter, which represents "feminine", plays a leading part in culture and art. So far as poetry is concerned, the image of moon has an overwhelming superiority. Aesthetically speaking, the moon spirit has been embodied in several ways. Moon is both the origin and the summit of such aesthetic standards as softy, sweetness and clearness, so it is reasonable that the image of moon has been regarded as aesthetic object in poetry much more frequently than the image of sun.
中华民族所处的独特的地理环境孕育出了农耕文明，在农业社会中，太阳对人们的生产生活具有绝对的控制与影响，因日而起的水旱灾害更加深了先民对太阳的畏惧与仇恨；而月亮在先民心中，不仅能促进农作物的生长，而且带来了与太阳相反的皎洁、清凉、闲适，所以月亮比太阳受到更多的欢迎；神话是是民族情感的载体，&后羿射日&与&嫦娥奔月&所映射的恨日爱月的集体无意识，在诗歌意象的选取中自然地流露出来，有助于&重月轻日&现象的形成；哲学上的&阴&&阳&范畴在人们社会生活的多个方面均有体现，但与&阳&直接同一的&日—君—父&三位一体控制了政治、伦理领域；而代表&阴&的&月—母—女&则在文化、艺术领域占据了突出地位，具体到诗歌中，则是月亮意象完全压倒日意象；审美上的月神精神，在月亮意象上得到了多方面的反映，月亮既是阴柔美、恬静美、澄澈美等艺术审美准则的来源，也是其最高体现，月亮意象自然比日意象更多地进入诗歌审美领域，成为审美对象。

contrived：做作的
相比Restlet,这导致了很多做作的(contrived)代码. 以Django为例,它并不天然支持在URI和资源之间映射的URI模板. 而Rails强迫在关系数据库和对数据的CRUD操作间使用一种不自然的映射,REST/HTTP方法导致一种令人不满意的结果:开发人员不得不在各种限制下工作,

nature：自然
值得注意的是,在西方作为" 自然 "(nature)看待的时间范畴,在五纪则只是"人事"(五事、八政)的关系映射. 以上九大范畴之间,显然都是"纯粹关系映射推衍":"映射"就是"推衍";而作为其基础的"纯粹关系"就是周敦颐之所谓"二五合凝"(两仪、五行的融通)的范畴

sea floor：海底
使用主动式声纳包含:侦测和定位水面下的物体、航海、通讯和映射(mapping)到海底(sea floor). 一般最大操作范围是10到100公里. 与其相比,被动式声纳只聆听海面下的声音,包含:自然的乱流(turbulence)、海洋生物和从潜艇和表面船舰发出的机械声.

texture mapping：纹理映射
为了更真实的绘制图形,还要考虑物体表面的细节纹理,这通常使用一种称为"纹理映射"(texture mapping)的技术把已有的平面花纹图案映射到物体表面上,并在应用光照模型时将这些花纹的颜色考虑进去,物体表面细节的模拟使绘制的图形更接近自然景物.
