| 1. | The content of this paper is data processing and design of lanzhou seismic array
论文的研究内容为台阵勘测数据处理与台阵设计。 |
| 2. | Annex 1 to the ctbt protocol had listed the 50 seismological stations ( arrays ) comprising the primary network of international monitoring system ( ims ) , and lanzhou seismic array ( ps13 ) was in it
Ctbt议定书附件1列出了国际监测系统( ims )中构成基本网络的全球50个地震台站(阵)的清单，其中包括我国兰州台阵( ps13 ) 。 |
| 3. | The result suggest that if there are enough distance combined by every site , the radius will be more accurate . the coherence method was mentioned early ( ota kulhanek , 1973 ) but no one used it to confirm redius of a seismic array
结果证明，只要台阵各勘址子台能够组合出较连续的距离值，则利用相干函数所求得的半径将更加精确。 |
| 4. | According to this kind of design method , the most important thing is to confirm the radius of the two rings for lanzhou seismic array on the principle of highest signal coherence combined with lowest noise coherence
根据这种设计方式，兰州台阵的设计主要是依据各测点间地震信号的最大相干性和噪声的最小相干性的原则来确定两个同心圆的半径。 |
| 5. | This paper also show a rough estimate of the gains of this array , because it needs one year ' s data to collect one year ' s noise correlation variation curves and then give a more practical detection ability of the seismic array . one result of this paper is " seismic array site survery data processing software " exploited by the author . the software can calculate the power spectrum of noise for every site , noise coherence function for every site pair , the cross - correlation curves , the root mean square of noise for every site and the array response
此外还计算了该台阵的台阵响应，发现台阵响应的主瓣高而尖；旁瓣很小，这歪姐钮远宣腔挝踏数公镀壁韶逼上拢唆精确啻应：有关此台阵的检测能力，只能给出一个粗略的估计，因为评价一个台阵对地震事件的检测能力需要获得为期一年的观测资料，才能给出一年内噪声场变化的相关值曲线，最终给出更加符合实际的台阵检测能力。 |
| 6. | The cross - correlation curves method as a traditional method is to find out the distance with the biggest snr to be the radius . the author tried a new coherence function method combined with the cross - correlation curves traditional method to confirm that the radius of the seismic array are 380m and 1500 - 1750m respectively
作者对比了各测点对之间的噪声和信号的相干函数并找出了信噪比最大的距离值，结合传统的相关值曲线理论得出了兰州台阵内外圆的半径分别为380m和1500 - 1750m 。 |
| 7. | Using the arrival times of 197 earthquakes well recorded by the beijing seismic network and the china - germany cooperative yanqing digital seismic array in the period from october of 2001 to december of 2005 , we accurately relocate these earthquakes by the joint - inversion program for hypocentralr position and 3 - d velocity structure
摘要利用首都圈地震台网和中德合作延庆数字地震台阵2001年10月2005年12月获得良好记录的197次地震到时，运用地震震源位置和三维地壳速度结构联合反演程序对这些地震实行精确定位。 |
