Firstly, this paper investigated roundly the basic theory of the ambient vibration method, analyzed systematically the main methods of ambient vibration identification, and discussed their advantages and disadvantages. Then we established the finite element model of structural dynamics and test model and analyzed their mutual relation, improved MUSIC method and correlation function method in the harmonic identification, and gave the subspace method and correlation function method based on continuous model, which is multi-harmonic retrieve technique. And then, this paper also puts forward least-squares method to estimate directly structural physical and modal parameters; this approach replaced the derivative operator in the continuous time model with an equivalent approximation, and estimated the physical parameters of structures by the least-squares method. And then, we discussed the approximation methods of derivative and their convergence. Finally, this paper researched the modal parameters of a frame structure by the simulation and test. The results demonstrated that subspace method, correlation function method and the least-squares method are effective and stable respectively.

The analysis of the chemical constitutes among sterns roots and leaves of Dracaena cochinchinenis, showed that there' s small amount loureirin A in their extracts, with 0.053mg/g, 0.058mg/g, 0.015mg/g respectively only. Therefore, the roots, stems and leaves of Dracaena cochinchinenis have too low contents of loureirins to be raw materials of dragon's blood.
分析剑叶龙血树根、茎、叶的成分,发现风干的剑叶龙血树根、茎、叶中没有龙血素B的存在,只含有少量的龙血素A,其含量在根、茎、叶中分别为:0.058mg/g,0.053mg/g,0.015mg/g,其含量远低于现行的龙血竭中龙血素A含量不低于2%的质检标准,因此剑叶龙血树的根、茎、叶不能直接用作生产龙血竭的原料。

XRD,X-ray EDS analysis,AFM and Fourier transform infrared spectroscopy were employed to characterize PbSe thin films. The results show that all of the films were heteromorphy and the growth temperature has effect to the diffract peaks of the films. The contents of PbSe thin films by PLD consisted with the targets,and realizing thin films deposited with same constitutes; the films had rather flatness surface and compact structure; the peak-to-tail roughness of PbSe thin films surfaces was less than 200nm;they had sensitivity to light of a specified wavelength and obvious absorption edge at 5μm corresponding to band-gap width of PbSe thin films;light of wavelength less than 5μm was strongly absorbed.
