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。

Using such methods as geochemistry engineering,plant reclamation technology etc,to make the harmful element harmless or to remove the harmful elements can effectively prevent the detonation of "the chemical time bomb" and eliminate the threat of "time bomb".

化学物质在土壤中的累积与储存，在相当长的时间内不表现为危害，但当储存量超过土壤或沉积物承受能力的限度时，或者当气候、土地利用方式发生改变时，原本稳定的化学元素会突然活化，导致

Say according to safe official, allegedly, the organization of the terrorist that act independently and Mohammedan extreme element is planning a basis " the kitchen is chemical " launch bomb assault, go up from the net the doctrine of the Mohammedan ultraism with bellicose derive, because this will fear the key of effort instead,turn to a network to become crucial.

根据安全官员称，据说，独来独往的恐怖分子和伊斯兰极端分子的组织正计划依据"厨房化学"发动炸弹袭击，并从网上汲取好斗的伊斯兰极端主义的学说，因此将反恐努力的重点转向网络变得至关重要。
