By employing the diffraction grating coupling technology and the basic theory of surface plasmons,we successfully excited the SPs along Al/air interface,and first observed the extraordinary enhancement and beaming effect of EMW transmission through a single subwavelength metallic slit in X-band microwaves.

利用表面衍射光栅耦合技术和表面等离子体激元的基本理论，成功地在金属铝的表面上耦合激发了表面等离子体激元，首次在微波的X波段发现了电磁波通过亚波长金属狭缝的超强透射和聚束效应。

This kind of problems is first changed into the model of perceptrons in neural theory, Under the assumption of a finite set of social states. a sufficient and necessary condition for single-valued choice functions to be sum-fuzzy implementable is obtained: a geometric characterization is also given: an efficient algorithm for the sumfuzzy implementation of single-valued choice func...

Several representations of numerical simulation, such as induced curvature, the conditions of first—type limit, second—type limit and singular solution, are presented under continuous and differential conditions. A new system of numerical simulation, which is relative as well as independent to traditional theory, is established.

The first chapter discusses the fundamental,the program and the core question of the sociobiology,and the contribution of Wilson to sociobiology.The second chapter discusses Wilson\'s early human sociobiology.The third chapter discusses Wilson\'s later gene-culture coevolutionary theory.The fourth chapter gives the author\'s own review,vindication and justification on Wilson\'s sociobiological thought.

空间向量引入立体几何，对传统的教育模式以及课程结构产生了很大的冲击和影响，对空间向量与立体几何结合的重要价值和作用得到了数学教育界的普遍关注，国内有不少人进行了大量的理论探索，但缺乏关注对一线教师与学生的实证研究。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
