Dizhen xuebao, 2021 利用远震资料、近场强震资料和合成孔径雷达干涉同震形变资料确定了2017年8月9日精河MS6.6地震的断层面参数及震源破裂细节。为得到可靠的断层几何参数，发展了一套基于InSAR数据滑动分布反演的三维格点搜索流程，对本次地震断层面的走向、倾角和震源深度进行了格点搜索。结果显示，地震断层面走向为95°，倾角为47°，震源深度为14 km。基于搜索得到的断层模型进行破裂过程联合反演的结果显示：精河MS6.6地震为一次单侧破裂事件，最大滑动量约为0.8 m，滑动区域集中在断层面上震源以西5—15 km ...

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Eutectic high‐entropy alloys (EHEAs) have attracted significant attention due to their balanced mechanical properties and promising applications. Nonetheless, the correlation between the solidification mechanism of eutectic microstructures and their mechanical properties remains elusive.

Dizhen xuebao, 2019 通过建立三维数值模型，对隐伏正断层在均匀错动和倾斜错动方式下土体的破裂过程进行研究。利用应力罗德参数和等效塑性应变分别对断层错动过程中上覆土体的应力状态和破坏形式进行分析，并提出土体破裂的判别方法。通过对数值模拟结果的分析得到以下结论：① 在断层错动过程中，下盘一侧受断层错动影响的上覆土体的应力状态经压剪→纯剪→拉剪逐渐变化，而上盘一侧上覆土体的应力状态变化较为复杂，经压剪→纯剪→拉剪→纯剪→压剪重复变化；② 在断层均匀错动过程中，断层下盘一侧土体的破裂率先出现在地表拉剪区内，随错动量的增大 ...

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 ...
