In the titration experiment of NMR and IR spectroscopy, we can understand how sensors binding with metal ions: the two carbonyl group and crown ether group cooperated in binding with metal ions. Furthermore, by altering the "oxygen" atoms of crown ether to "sulfur", we can change the binding affinity to the soft metal: cupper. It shows 60-fold enhancement of fluorescence.

在化合物2中，我们引进了硫原子在冠状醚中，则应对电子密度较低之金属有较好的结合能力，实验结果显示了此分子对铜离子有相当好的选择性和结合能力，萤光增加可达60倍；同时由红外光吸收光谱和核磁共振光谱滴定实验可确知，香豆素衍生物上的两个羰基对金属离子的选择性及结合上扮演相当重要的角色。

"Benefits of the collaborations cut both ways," says Hans-Dieter Klenk, head of Marburg University's Institute of Virology, who led the delegation."Germany has good basic research experience with coronaviruses."

Aiming at solving the problems of heterogeneity among ontologies in semantic Web services, and taking into account the fact that the efficiency of most ontology mapping system is not high and the results of ontology mapping is not accurate enough, this paper proposed efficient ontology mapping method and system framework for semantic Web services, the method adopted machine learning techniques to enhance the degree of automation of ontology mapping, used comprehensive evaluation technology to amend the results of ontology mapping, so as to improved the accuracy of ontology mapping.

芦明， 李冠宇，史一民大连海事大学信息科学技术学院，辽宁大连 116026）本体的异构性阻碍了语义网服务的互操作。从解决语义网服务中本体的异构问题出发，同时考虑到目前的本体映射系统大多效率不高、映射结果不够准确的问题，提出了一种适用于语义网服务的本体映射方法及系统框架。该方法利用机器学习技术来提高本体映射的自动化程度，利用综合评判技术修正映射结果，以提高本体映射的准确率。
