The haisic products are 1,2-, 2,3- and 3,4- diamines of dibenzothiophenes. Orto-diamines react with hydrochloric acid and sodium nitrite and obtain three new isomeric heterocyclic systems： 3H-benzothieno[3,2-e]benzotriazole, 3H-benzothieno[2,3-f]benzotriazole and 1H-benzothieno[3,2-g]benzotriazole with the anticipated biological activity. Their spectral characteristics are studied.展开更多

Running on Internet, integration based on muhilayer federation architecture and dynamic reuse of simulation resources are the major difficulties for complex product collaborative design and simulation. Since the traditional Run-Time Infrastructure （RTI） is not good at supporting these new requirements, an extended high level architecture （HLA） multilayer federation integration architecture （MLFIA）, based on the resource management federation （RMF） and its supporting environment based Service-oriented architecture （SOA） and HLA （SOHLA） are proposed, The idea and realization of two key technologies, the dynamic creation of simulation federation based on RMF, TH RTI, an extensible HLA runtime infrastructure （RTI）, used at Internet are emphasized. Finally, an industry case about multiple unit （MU） is given.展开更多

It is shown that every Coleman automorphism of G is an inner automorphism. As an immediate consequence of this result,it is obtained that the normalizer property holds for G.展开更多
