| 4. | By collecting and coordinating the seismic damage data of earthquakes with m 6 in beijing acid its adjacent area since 1000 , we establish a gis - based platform on the historical earthquakes in beijing
摘要通过对公元1000年以来北京市及附近地区6级以上地震震害资料的收集和整理，采用gis技术，建立了北京市历史地震的地理信息系统技术平台。 |
| 5. | Furthermore , the author study the character of the earthquake factor through researching into historical earthquakes of the investigated area and engineering seismology , it insures the reliability of reverse calculation parameters
此外，本文还着重从历史地震统计及工程地震学的理论研究出发，分析地震参数的取值，从而保证了反演参数的可信度。 |
| 6. | In this paper , according to the periodically active characteristics shown in the historical earthquake data in this region since 1900 , we describe the rule of seismicity with sine function and furthermore make a preliminary forecast of the seismicity intensity and the developing trend in northeast china till the year of 2008 by using the periodogram of time sequence and other analytical methods
摘要根据东北地区1900年以来的历史地震资料所显示的周期性活动特点，用正弦函数描述其地震活动规律，并结合时间序列的周期图及其他一些地震活动性分析方法，对该地区未来1 ~ 3年地震活动发展趋势和地震强度作了初步预测。 |
| 7. | On the basis of the characters of geological structure and the changes of time and space of historical earthquake , according to the indexes of li yulong ' s earthquake zone . the regionalization of earthquake damage in baoji city is put out , this is that there are two dangerous earthquake regions which line of longxian - qianyang - baoji urban and meeting region of qishan - fufeng - meixian , and one earthquake stable region
摘要根据宝鸡市地质构造特徵与历史地震的时空变化及李玉龙的地震带的划分标准，将宝鸡市划分为两个危害性地震地区：陇县千阳宝鸡市区；岐山、扶风、眉县交界地区与一个相对稳定区。 |
| 8. | 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。 |
| 9. | The sequence and activity characteristics of shuikou reservoir induced earthquake are analyzed with several methods , such as probabilistic evaluation , comprehensive effect parameter e evaluation , two - step comprehensive fuzzy evaluation , the maximum magnitude of historical earthquakes evaluation , etc . . the results show that the shuikou m ( subscript l ) 4 . 1 earthquake on april 21 , 1996 is a main - earthquake , and from now on , the possibility occuring m ( subscript l ) > 3 induced earthquake in shuikou reservoir area is low
摘要应用概率法、综合影响参数预测法、两级模糊评判法、古登堡里克特公式外推预测法等对水口水库诱发地震序列以及活动特征进行了研究，认为： 1996年4月21日发生的m (下标l ) 4 . 1地震为水口水库诱发地震主震，今后库区发生大于3级以上诱发地震的可能性较小。 |
