查询词典 seismic

Formula. At the same time, the article raised the seismic reduction factor formula for the SSDI system.The paper adopts finite element method based on the ANSYS procedure, and realizes the simulation of soil constitutional relationship through choosing Davidenkov soil model with proper parameters and using restartup method in ANSYS. Then, the procedure makes the soil nonlinearity simulation come true byusing parameter design language of APDL. Element Combin14 is be used to simulate viscoelastic boundary and radiation damping effect. At the same time, it presents integrated damping matrix for considering the coupling of different damping of soil and structure.

The digital clock SZZ-Ⅰ and receiver BPM are the main components of the equipment .The have been working in the large telemetric seismic networks of our country such as Chengdu and Zigong in Sichuan Province, Sanxia Reservoir on the Yan gtse Reiver,and Cheyan Reservoir in Hubei Province,Lhasa city in Tibet,and Longyanxia Reservoir in Qinghai Province.

其核心部件：SZZ-Ⅰ型数字钟和BPM接收机，先后被成都遥测台网，自贡遥测台网，丹江水库台网，西藏遥测台网，隔河岩水库，龙羊峡水库，长江三峡水库前期台网等国家大中型遥测台网选用，均获得了优良的时间服务，为台网的高可靠，高质量运行提供了保证。

By analyzing the correlativities between the seismic record and the surface structure, it was confirmed in this paper to be a coincidence relation between the topographic feature and the surface structure of HJQ. For the reliableness of the refraction statics, the policy of the first arrival pickup and the initial model setup should be adapted to the various topographic features in the use of this technique.

本文通过对杭锦旗地区特殊地貌与地震记录初至及表层结构的对应关系分析，认为杭锦锦地区地貌与表层结构有一定的对应关系，在折射静校正处理中应针对不同地貌特征建立初至拾取原则和构建初始模型，以确保折射静校正结果的准确可靠。

Afterwards of this one act causes the United States 24 days after each remonstrant tide of big city, 25 days are to be in the United States more city causes los angeles of coastal California city on the west " remonstrant seismic sea wave ", the number that joined los angeles to parade greatly that day is as high as 50 much.
