| 摘 要： | 在哈萨克斯坦的5个现代化数字地震台阵中，4个小孔径同心圆结构的IMS简约型台阵建设、维护方便，全方位监测能力强，1个十字型结构中等孔径台阵，因对特定方位敏感，对更远距离已知核试验点监测能力更强。台阵观测场地均处于完整稳定的构造块体，内部岩石迁移性良好，噪声水平低，保证了对远处微弱地震信号的监测及各子台信号的相似性。地震检波器良好的性能，保证了台阵的地震信号记录质量和数据研究基础。采用卫星传输方式，有效保证了数据的实时性。哈萨克斯坦的地震台阵，其选址、布局、仪器、数据传输等台阵建设，为中国地震台阵发展建设提供了经验借鉴。

| Abstract: | Among Kazakhstan's five modern digital seismic arrays, 4 IMS simple arrays with smallaperture concentric circle structure are easy to construct and maintain and have strong omnidirectional monitoring capability, 1 cruciform medium-aperture array is sensitive in a specific orientation and has stronger monitoring capability for more distant known nuclear test sites. Seismic array observation sites are located on a complete and stable structural block that is formed by rocks with excellent transfer characteristics and low seismic noise level, which ensures the monitoring for distant weak seismic signals and the similarity to the sub-stations'signals. The good performance of the seismometer guarantees the seismic signal recording and data analysis of the array. The satellite transmission of data effectively guarantees the real-time transmission of data. The construction of the Kazakhstan seismic arrays, including its site selection, layout, instrument and data transmission, has provided an experience for the development and construction of the China seismic arrays. |
