怀涿盆地北缘断裂带土壤气体地球化学特征

Dizhen xuebao, 2023
在河北怀涿盆地的郝家坡和小水峪布设两条测线开展了四期土壤气Rn，CO2和Hg的浓度测量，并基于此研究该盆地北缘断裂带南西段和北东段土壤气地球化学特征的空间分布差异及其与断裂活动的关系。结果显示：郝家坡剖面土壤气Rn，CO2和Hg的浓度平均值分别为8 371.16 Bq/m3，0.85 %和14.82 ng/m3；小水峪剖面土壤气Rn，CO2和Hg的浓度平均值分别为2 813.18 Bq/m3，0.42 %和13.08 ng/m3，可见郝家坡地区土壤气Rn，CO2和Hg的浓度平均值均高于小水峪地区 ...

区域宽频地震波形反演所揭示的2022年青海门源MS6.9地震震源破裂过程

Dizhen xuebao, 2023
基于有限断层模型反演方法，利用区域宽频带数据反演了2022年1月青海门源MS6.9地震的震源破裂过程，并结合地质构造与地震重定位结果判断发震断层走向。综合反演结果表明：此次地震的发震断层走向为WNW向，主要以走滑为主；破裂主要发生在震源两侧，可能存在着双侧破裂，在震后2 s和9 s出现破裂极大值，最大错动量约为1.5 m，位于深度约6 km处，发生明显破裂的深度约为16 km，地表破裂长度约20 km；此次地震释放的标量地震矩为1.23×1019 N·m，相当于矩震级MW6.7，地震能量主要在前15 ...

Visual Sedimentation [PDF]

IEEE Transactions on Visualization and Computer Graphics, 2013
We introduce Visual Sedimentation, a novel design metaphor for visualizing data streams directly inspired by the physical process of sedimentation. Visualizing data streams (e. g., Tweets, RSS, Emails) is challenging as incoming data arrive at unpredictable rates and have to remain readable.
