This article mainly established the analysis method to extract the oxine-copper residues in cucumber and soil with ion pair of antiphase HPLC and Ultrasonic-assisted solvent. This method mainly uses XBridge C18 column and UV detector by using waters phase of phosphatic buffered solution/acetonitrile (60:40, by vol) as mobile phase with 0.8 mL/min flow ratio and UV detection at 250 nm. The residue time was 4.71 minute. Accuracy, precision, and sensitivity of the method all satisfy the demands of pesticide residue analysis.

建立了黄瓜和土壤中喹啉铜的超声波辅助溶剂提取－反相离子对高效液相色谱法的残留分析方法，该方法使用XBridge C18色谱柱和可变波长紫外检测器，并以水相磷酸盐缓冲溶液－乙腈（体积比为60：40）作流动相；流速为0.8 mL/min；检测波长为250 nm；保留时间为4.71 min；该方法的准确度、精密度及灵敏度均满足农药残留分析的要求。

Appling the method to multi-channel filter design, we find that the filter efficiency can improve about 50% when the dielectric rod radius is proportion with ransonant cavity dielectric rod radius.

The objective of this study was to compare and differentiate the different removal mechanisms of the dissolved organic matter in the secondary effluent during the granular activated carbon adsorption, horizontal subsurface flow wetland treatment, sand column treatment, laboratory-scale soil aquifer treatment and GAC+SAT.

通过模拟活性炭吸附、砂柱处理、土壤含水层处理、GAC+SAT及潜流式人工湿地处理实验，研究了城市污水处理厂二级出水中溶解性有机物在吸附、生物降解及生物与吸附的共同作用等具有不同DOC去除特点的处理过程中的去除及转化机制。

Finally, the paper provides the checking computations of themost dangerous cases of the cast ball-and-socket support node planned to be use in thedouble-layer reticulated dome roof of Laoshan Cycling Gymnasium for BeijingOlympic Games. The node under most dangerous cases is analyzed by ANSYS7.0 toget the distribution of stress and assurance coefficient. All these results can be thetheoretical warranty for the use of project of Beijing Olympic Games

最后，对北京奥运会老山自行车馆双层球面网壳柱脚拟采用的铸钢球铰支座节点在最不利工况下节点承载力进行了验算，并通过ANSYS7.0对节点在最不利工况下的应力分布进行分析得出了节点在这些工况下的安全系数从而为在北京奥运会老山自行车馆工程中使用这些节点提供了理论依据。

MS1-5 directed against CSP could confer protection to mice or rat against a non-lethal inoculation of parasites by inhibiting the invasion of sporozoites into hepatocytes and neutralizing their infectivity.

In the VR interactive interface provided by the software, a GTAW arc geometrical 'model has been constructed in two-dimensional (2D) axisymmetry through main menu. Using PHOENICS code and developing it secondly, a series of subroutines has been programmed in the Ql file and GROUND file. Boundary conditions and special sources about temperature profile .velocity and potential profile have been loaded by these subroutines.
