Thirdly, a new type base isolation system, i. e., slide-limited friction base isolation system is presented in this paper. Based on this system, harmonic and subharmonic periodic response of S-LF subjected to harmonic motion is investigated by using Floquet theory. Dynamic response of sliding structure subjected to earthquake ground motion is calculated with a precise high order direct integration method, and the numerical results are presented in terms of maximum acceleration response spectra of supcrstructure and maximum sliding displacement response spectrum. By comparison with isolating effects of pure-friction base isolation system and resilient-friction base isolation system , it shows that the isolating characteristic of S-LF is superior to P-F and R-FBI. Through analyzing an engineering example, it is observed that the maximum inter-storey shear force and absolute acceleration of sliding structure to earthquake ground motion are very different from those of traditional structures.

In this research, swainsonine contents of three Oxytropis species were determined by the high performance liquid chromatography coupled to mass spectrometry. The population genetic diversity was also studied and the swainsonine related molecular markers were screened by ISSR. In vitro fungi cultures from the individual plant of O. glabra were performed and microbiological morphology of the colony and the conidiophore were investigated. The 5.8S rDNA/ITS sequences of fungi amplified from total DNA in both plants and fungal endophytes were studied. These sequences were analysed and compared, and they were also compared to the 5.8S rDNA/ITS sequence of fungal enduphyte Embellisia sp. L12 from the O.lambertii, O.sericea and A.mollisimus distributed in USA.
