The works in the project just done can be summarized as five respects.(1) A device was designed to fabricate the asymmetrical resonant cavities by a pendant drop. A series ARCs with variable parameters provides a valuable experimental method for investigating the characteristics of ARCs.(2) The relationship between the number of active modes and the shape parameters in an ARC was investigated. The experimental lasing threshold was compared with theoretical result, the good agreement between two shown that it was the decrease of the number of active modes in an ARC that decreased lasing threshold.(3) Dye lasing gain was used to enhance the signals of stimulated Raman scattering of the weak gain Raman modes in a circular cavity made by a pendant drop, the instantaneous SRS spectra of weak gain Raman modes in ethanol was obtained by this new method.(4) The SRS signals of minority compound in a binary chemical complex was obtained by using dye lasing gain method. The detection concentration of minority compound was reduced to an order compared with normal SRS method.(5) A cylindrical circular cavity was formed by a liquid jet, which was used to reduce the pump intensity required for laser induced plasma spectroscopy. The limit of detection of trace element in aqueous sample was greatly decreased by this new method.
我们设计并成功制作了使悬垂液滴连续变形的装置,用此装置可以方便地改变非圆对称谐振腔的几何参数,为ARCs的研究提供了一种有效的实验方法;研究了ARCs中活性模式数和变形参数间的变化规律,激光阈值的数值计算结果和激光辐射的实验结果作了比较,二者吻合的曲线说明ARCs中活性模式数量的减少是受激辐射放大阈值降低的原因;在由单元化合物构成的微型圆对称谐振腔中,首次尝试用"激光增益"增强弱增益拉曼模式的受激拉曼散射信号,获得了乙醇分子中弱增益拉曼模式的瞬态SRS光谱;在由二元混合物构成的微型圆对称谐振腔中,用染料的激光增益增强了少量化合物的SRS信号,把少量化合物的SRS信号探测浓度降低了近一个数量级,在SRS应用于瞬态过程的组份分析方面做了卓有成效的探索;用石英毛细管形成的稳定液拄构成拄形谐振腔,降低了激光诱导等离子体光谱需要的激励能量,有效地降低了水相样品的痕量元素分析极限,为LIPS应用于微量元素的化学分析开拓了一条新的技术路线。

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。
