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.

On one hand, the integration between literary autonomy and social heteronomy is the abscissa of the coordinate axis. On the other hand, the integration of ancient and present poetic resources, and Chinese and western poetic resources is the ordinate of the coordinate axis. Integration in Wu Mi\'s poetic thoughts is embodied in two aspects: Firstly, it means the integration of ancient and present poetic resources, and Chinese and western poetic resources. Wu Mi maintains that various poetic resources should be treated equally so as to find the similarities and differences among them. Only with a broad cultural view and calm attitude toward various poetics resources can a new system of modern poetics be achieved.

Based on collected drill hole materials and predecessor publication\'s dates on seabed sediments physical and mechanical characters in the Yellow River subaquatic delta,the distribution and engineering geological nature of this area sediments are studied systematically;though the analysis geotechnical achievement tables and compression curves of those data,the layered summation was used to calculate the final subsidence quantity;Terzaghi consolidation theory was calculated and the Plaxis software was simulated subsidence with time changes;based on measured dates and other method,the quantitative analysis results were verified,Finally this study analyzes influencing factors and proposes control measures and proposals.

This winter severely cold causes the port city partial seafood cultivation to lose in a big way, some fishing boats are also frozen in the wharf, approached the shore several pools to tie an about two centimeters thick ice, was apart from the shore far pool also to float some ice pieces, he said approach shored in these pools raised is the trepang, their Pi Caorou was thick, the day cold has drilled to under the pond bottom stone, will therefore not be frozen to death, so long as the oxygen deficit line, did not compare the trepang, how the abalone not anti-has frozen, because Bao fish flesh direct dew in outside, so long as in pool oneIces up, will have many abalones to freeze to death, transported south early the abalone is good.

烟台分类妈妈消息，今天一尾号是6215的网民来电说想告诉大家一条关于的相关信息：今冬严寒造成港城部分海鲜养殖损失较大，一些渔船也被冻在码头，靠近岸边的十几个池子都结了大约两厘米厚的一层冰，距岸较远的池子里也漂浮着一些冰块，他说靠岸的这些池子里养的都是海参，他们皮糙肉厚，天冷了就钻到池底的石块下面了，因此不会被冻死，只要不缺氧就行，相比海参来说，鲍鱼就不怎么抗冻了，因为鲍鱼肉直接露在外面，只要池子里一结冰，就会有很多鲍鱼被冻死，早早把鲍鱼运南方就好了。
