This problem is also important and valuable in Nonlinear Optics. It will be very helpful to understand how the aberrations affect the course of three- wave mixing, such as the change of conversion efficiency, the distribution of intensity and phase.Small signal solution of aberrated second harmonic generation is deduced from three-dimension three wave coupling functions. The numerical work gives out lot of results of different aberrations. The effects of the fundamental waves aberrations, which will change the conversion efficiency, distribution of intensity and phase in the frequency conversion, is analyzed. It shows that when walk-off and diffraction effects could be ignored approximately estimation of the phase distribution of second-harmonic wave could be done. The far field divergent angle and second moment radius of harmonic wave will vary with the aberration of fundamental wave, but the far field divergent angle will be obviously smaller than that of fundamental wave. The phase distribution of both fundamental and harmonic wave is measured using Hartmann-Shack wave front sensor in the experiment with 1064nm and 790nm lasers, respectively. Results are given.

首次从三维三波相互作用方程组推导得到了位相畸变光束倍频的小信号解；通过建立国防科学技术人学研究生院学位论文三维数值模型，编写相应仿真程序，首次得到了位相畸变光束倍频过程的大量计算结果，深入细致地研究了位相畸变光束经非线性光学频率变换后谐波的转换效率、光强分布、位相分布以及影响它们的各种因素；得出谐波的远场发散角和光斑二阶矩的变化规律会因为基波像差的不同而不同，但谐波的远场发散角明显地比相应基波的小的结论；得到了在走离效应和衍射效应等影响许多因素可以忽略的情况下，位相畸变传递到二次谐波的估算式；举例分析了KDP三倍频方案中，基波位相畸变对二次谐波和三次谐波的影响；实验工作中，用哈特曼一夏克传感器分别对IO64nm倍频过程和790飞秒超短脉冲倍频过程中的基波和谐波的位相分布进行了测量，给出了相应结果。

The ceo of thedhgate ,wang shutong ,is the perfect example of the ambition and action.after gratuation she worked as a teacher in qinghua university,which was envied by others.but she was not satisfied with the comfortable life.her tough will resulted in her enjoying the challenge.after two years,she resigned and left the henhouse,and manged to be employed by microsoft ,flied in the sky.she broke through all restraint and found her own area.ever since she warned herself she must be on the ground,modest and donot aim too high .six years of hard work made her the employee who promotes fastest among the colleaguesand the youngest department manger.however, it was the beginning of her dream .when everyone thought she would work continually she resigned again.which was decided after consideration.her dream was to start her own business.with the dream driving,she undertook to set up the dhgate.in the beginning the life was so difficult that many things were waiting for her,but she didnot move backand faced the difficulties.

敦煌网首席执行官王树彤就是抱负与实践完美结合的典范。毕业后留在清华任教的她让旁人羡慕之极，但自己却并不满足安逸的生活，坚韧的意志力铸就她生性喜欢挑战。两年后，她毅然辞职，离开鸡舍，过五关斩六将闯入外企微软，飞向了天空。理想与实践使她冲破世俗的禁锢，找到了自己天空。进入微软后，她告诫自己要脚踏实地，谦虚谨慎，不要好高骛远。六年的踏实苦干使她成为同期进入微软而升职最快的人，且是中国最年轻的部门经理。然而这只是王树彤梦想的开始，当所有人都认为她会继续留在公司发展的时候，她辞职了，但绝不盲目。因为她知道自己的梦想是创业。终于在梦想的驱使下，她再一次付出了果敢的行动创办了如今的敦煌网。创业初期异常艰难，有很多很多琐碎的事情要自己做而且有很多很得困难需要自己去解决，但她并没有退缩，而是迎难而上。

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。
