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.

Experimental results indicated that the first canonical correlation coefficient and the second canonical correlation coefficient was 0.8451 and 0.7843 respectively, they have constituted 91.37% of the total correlation. The first canonical variable (V1) of the response signals group had certain predicted ability on physicochemical index of milk, but the predicted ability was a little weak, response signals of ZZ sensor(X1)、CA sensor(X4) and JB sensor(X7) played a crucial role .At the same time, four canonical variable V and W have explained 42.49% and 43.25% of the total variances of the other group respectively.

试验结果表明：第一典型相关系数和第二典型相关系数分别是0.8451 和 0.7843，前两对典型变量共占总相关的91.37%；响应信号组的第一典型变量(V1)对牛奶理化指标具有一定的预测能力，但预测能力较弱，起主要作用的是ZZ传感器响应信号(X1)、CA传感器响应信号(X4)和JB传感器响应信号(X7)；与此同时，V和 W 的四个典型变量分别解释另一组变量总方差的42.49%和43.25%。

Based on the analysis of relevance weight among output signals the method constructs the set group of output signals with minimum relevance weight to reduce the loss of fault coverage using grouping compression,and the method needs no auxiliary circuity.

该方法是在分析输出信号之间相关性的基础上，根据给定的MISR阶数构造具有最小相关度的输出信号集合组，以此来减少输出信号分组压缩时的故障覆盖率损失。该方法不需附加任何辅助电路。

Although translator has turned from being a crystal ball by which the original culture can unrestrainedly penetrate to another crystal ball by which the target culture can freely traverse, the translator's personal embodiment, in the process of cognitive act, are still absent in translation studies. Translators are still subjects without body or simply disembodied subjects.

译者虽然由原语文化可以自由穿透的玻璃球变成了译语文化可以自由穿越的玻璃球，但译者认知过程中的个体体验在翻译研究中依然缺席，译者依然仅仅是一个没有躯体体验的主体。
