Examples
- Seventeen potential earthquake source areas were divided in the region according to the dividing principles and the signs of earthquake source areas
根据划分潜在震源区的原则和标志，在区域内共划分出17个潜在震源区。 - By using the data of comprehensive mechanism solutions of small earthquakes and suing the signs of initial p wave recorded by seismic recording , the dynamic changes of stress field of small earthquakes occurred before four moderate - strong earthquakes in north china have been studied
使用由地震记录p波初至波符号求取的小震综合机制解资料，分析研究了华北地区4次中强地震前震源区及其附近小震应力场的动态变化。 - This paper discussed two problems in current seismic safety evaluation for engineering site , i . e . , the requirements of seismotectonic investigations and evaluation in near site area ( near region ) at the different seismic work levels ; and consistency between seismogenic structure and potential earthquake source with deterministic method and probabilistic method in engineering site seismic work at i - level
摘要本文讨论了目前工程场地地震安全性评价工作中大家关心的两个问题：不同级别地震工作的近场区（近区域）地震构造调查和评价的不同要求以及级工作中确定论和概率论分析方法中发震构造与潜在震源区的统一性。 - Combined with some previous results , we have generalized preliminarily the dynamic evolution characteristics of stress field in the focal region and its adjacent area before moderate and strong earthquakes , and tried to give out the judgement index of earthquake prediction with the comprehensive mechanism solution of small earthquake
结合前人的有关研究成果，综合归纳了中、强地震前震源区及附近应力场的动态演变特征，并尝试给出了小震综合机制解参数预报地震的判据指标。 - By using the projective covering method and projective covering probability , fractal and multifractal dimensions of different types of landform sueface above are computed . results show that all the studied landform surface are not simple fractals , but multi - range scaling fractals , and the fractal dimensions increase with the landform type from basin to mid - low mountain and high mountain . nevertheless , different type landscapes perform different dq - q curve shapes . which the dq value has the widest range in the high mountain type , the second one is the mid - low mountain type , and then the basin type
对不同时段地震形变场图象多重分形特征的研究表明，震源区及近震源区强震前垂直形变图象都出现信息维降低，多重分形谱曲线dq变陡，值域范围变宽的特征，说明在强震前地壳垂直形变出现了局部化、不均匀性增强的行为，这些对地震预报都有重要的实际意义。
