Finally, it is our most important chapter which discus the two-level systems which interacted with the Shaping-pulse dynamic progress of the absorption, dispersion and refractive index.

在后面几部分的讨论中就会发现，采用布洛赫矢量方法讨论激光脉冲同系统的相互作用，可以形象直观的从理论上观测到色散和吸收或辐射的动态演化过程，既有利于教学演示，又有助于帮助实验寻求更方便的激光整形方式。

The results show that the optimum mole percent of Al3+ to Yb3+ is 9—11 for high concentration of ytterbium-doped silica-based fiber at which low concentration quenching probability, high absorption coefficient and proper numerical aperture can be obtained.

揭示出在高掺Yb3+的石英基光纤中，共掺Al3+的摩尔浓度为Yb3+摩尔浓度的9—11倍时既可以减小Yb3+的浓度猝灭概率，又可以获得高吸收系数，同时还可更好地满足数值孔径的要求的结论。

Ideological and practical work, in fact, is both abstract and concrete category, which covers wide range.

虚与实实际上是一对既抽象又概括的范畴，它涉及的范围很广，大凡诗词、文学、雕塑、绘画等一些艺术领域都会遇到虚实关系的问题。

Its significance not only takes root in the tradition of abstract expressionism of western modern art, but also relates to the calligraphic aesthetics of Chinese traditional arts.

其意义诠释，既植根于西方现代艺术中的抽象表现主义传统，又同中国传统艺术的书写美学相关。

The education with reality close to student's mentality, especially mathematics, abstract concept but reality.

紧密联系生活实际的教学符合学生的学习心理，尤其是既抽象又与生活密切联系的数学知识。

It is more a compressed and stretched rendition of the abstract space.

它既不能完全的抽象，又不是完全的具象，在乎你看作品，你对作品是直接面对它呢，还是通过另外一种方式去看它的时候，你会产生一种完全不一样的转换，比如你看原作的时候，你面对它的时候可能你会觉得它是一张非常抽象的作品，你完全找不到一个具象的东西在里面，但是你把这张画缩小到足够小，好像邮票那么大的时候，你是一眼可以认出它是一个非常具象的空间，这是我觉得我的画里面最有意思的地方。

Absurdness refers to the conventions of sexual behavior. The protagonist looks like a businesswoman. To be successful

女主角一身职业女性装扮，摆出彩虹的造型，既鬼魅又颇为荒诞，隐射传统性别
