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.

Asset valuation of our country began later than western countries, although develops quickly, but compare with the developed countries it still exist many differences in above-mentioned aspects:Purpose of evaluation are limited, the main purpose of patent valuation in our country are for the patent property's cost amortisation, trade and investment, besides, neglecting the purpose of patent evaluation a service management and litigation;The application of evaluation theories are subjected to a limit, the method we commonly use is income method, the world well-known evaluation organizations pay more attention to a lately theoretical application;Evaluation standards are established lagard, on the countrary, the International Valuation Standards, The Uniform Standards of Professional Appraisal Practice and the European Valuation Standards were all established very early,and have already become a careful and reasonable structure system after emendations, but the valuation standards of China does't shows the relation between accounting standards now, demand of valuators' responsibility are too brief, having no restriction to definitude the type of value, and the regulation of valuation methods of Intangible Assets is not comprehensive;The lawmaking isn't complete, our country has no complete lawmaking to carry on rules and regulations to the non-cash's property, patent infringement control are inadequate, and excessively restrict patent property contributed form.
我国资产评估行业起步较晚,虽然发展迅速,但经比较研究发现,在上述方面与发达国家仍存在很大差异:评估目的相对狭窄,我国主要以专利资产成本摊销、交易和投资为目的进行评估,忽视了专利服务管理和诉讼为目的的评估;评估理论应用受限,我国主要应用收益法,世界知名评估机构更注重新理论的应用;评估准则制定落后,无论是国际评估准则、美国评估准则还是欧洲评估准则,都制定较早,并多次修订已形成严密的结构体系,而我国在评估准则中未体现与会计准则的关系,对评估师执业责任的要求过于简练,没有对价值类型加以明确,对无形资产评估方法的规范也不详细;立法不完善,我国没有相对完善的立法对非现金出资进行规制,对专利侵权控制力不够、专利出资形式限制过多。
