| 1. | Compact disc a new carrier of earthquake records 地震记录的新型载体 |
| 2. | I am a civil engineer from beijing ( peking ) , and i am study the earthquake recording time history of chichi curve , nantou 本人是一名来自北京的土木工程师,要研究发生在南投的地震波(集集波) ,不知这里的老师们或者哪位同学有否收集? |
| 3. | Only after the reliability and reality of historical earthquake record are insured , the historical earthquake parameters obtained thereafter would be reliable and useful 在历史地震记载的真实性、可靠性确定之后,确定的地震参数才可信、可用。 |
| 4. | According to the different responses under different earthquake records , this paper studied the long - period character of this kind of vibration control structure also 通过本文提出的简单方法进行分析得知,该减震层的力学参数大体上是合理的。 |
| 5. | Furthermore , the optimization of the parameters of the frame with friction energy dissipation under several earthquake records is solved . examples are illustrated to verify the method 此外,还解决了多种地震波输入下摩擦耗能框架的优化问题,并通过算例进行详细的解析。 |
| 6. | The reliability of the method was examined with the actual earthquake records and it indicated that by using the present approach not only the liquefied sites and the stiff non - liquefied sites were identified , but also the soft non - liquefied sites were detected 结果表明:以此为基础建立了一套应用本文提出的方法,不仅成功地识别了液化场地和非液化硬土场地,也成功地识别了软土但非液化的场地。 |
| 7. | Based on the analysis to fourier , wavelet and hilbert - huang transform , the application of hilbert - huang transform in the analysis of strong earthquake records is discussed with 60 strong aftershocks in jiji earthquake series 摘要在简要地介绍比较了傅立叶变换、小波变换、希尔伯特黄变换理论的基础上,针对集集地震大量强震记录进行各种变换分析比较,以探求希尔伯特黄变换在强震记录分析中应用的前景。 |
| 8. | 3 . according to the classifying of the earthquake records , the influencing degree of different ground motions to the eccentric buildings is researched . the response of the irregular rc frame under the strong ground motions is analyzed using the fiber models 3 、根据地震动类型的划分标准,考察了各种类型的地面运动对偏心结构非弹性反应的影响程度;采用纤维模型梁柱单元分别模拟了单层和多层不规则结构在不同类型地面运动作用下的强震反应过程,对结构的变形峰值与滞回耗能情况进行了考察。 |
| 9. | Through several historical earthquake investigation cases , we found that the following aspects should be paid more attention in studying historical records of earthquakes : ( 1 ) discrimination and verification of historical records ; ( 2 ) application in evaluation of historical earthquake records ; ( 3 ) investigation of historical data without earthquakes ; ( 4 ) application in investigation of historical administration area and place name 摘要本文通过具体实例说明在查阅历史地震记载资料时应特别注意以下几个方面: ( 1 )地震历史记载的辨别; ( 2 )地震历史记载资料评价的应用; ( 3 )无震历史记载的查证; ( 4 )历史行政分区和地名考证的应用。 |
| 10. | Daqing region is situated in the middle - north of songlao basin , the tectonics inducing earthquakes in this region are mainly influenced by the pressing force of the pacific plate to the northeast asian continent , there were 6 earthquakes , which ms were not less than 6 . 8 among the earthquake records in the history , and the most dangerous earthquake occurred in 1119 大庆地区位于松辽-张广才岭构造区松辽盆地的中北部,发震构造主要受太平洋板块向东北亚大陆俯冲产生的推挤作用力的影响。自有地震记录以来,重点工作区内共记录到ms 4 . 7级地震6次,其中6级以上地震2次, 4 . 7 ms 6级地震4次,最大地震是1119年扶余6 . 8级地震。 |
