中文摘要
小行星9628494 本研究是利用长周期、宽频带数字资料约束弹性和非弹性结构,定义地球大尺度结构的继续。 目前的重点是将分析推向更小的长度尺度,并纳入各向异性的影响。 将扩大地震数据集,以扩大全球覆盖面,在当地增加密度,使区域规模的研究可行,并提高衰减测量的精确度。 从这些研究中获得的平均旅行时间也是有用的,在新的一维模型的发展和在评估的吸收带的旅行时间的频率依赖性的效果。 将根据体波的偏振或粒子运动开发新的数据集;预计这些数据集将对小尺度结构和各向异性敏感。 将研究新的参数化方法,使区域密度增加,以适应新数据集分辨率的提高。 ***
英文摘要
9628494 Masters This research is a continuation of the definition of the large- scale structure of the Earth by means of the use of long-period and broad-band digital data to constrain elastic and inelastic structure. The current emphasis is on pushing the analysis to smaller length scales and on incorporating the effects of anisotropy. Seismic data sets will be expanded to improve global coverage, locally densify to the point that regional-scale studies are viable, and improve the precision of attenuation measurements. The mean travel times obtained from such studies are also useful in the development of new one-dimensional models and in the evaluation of the effect of the absorption band on the frequency-dependence of travel times. New data sets will be developed based on the polarization or particle motion of body waves; they are expected to be sensitive to small-scale structure and anisotropy. Research will be done on new parameterizations which allow regional densification to accommodate the improved resolution of the new data sets. ***
