引言rn据中国地震台网中心测定,北京时间2022年1月8日01时45分,中国青海省海北州门源县发生了M6.9地震,震中位于( 37.77°N, 101.26°E),震源深度为10 km.在地震发生后,作者利用震源破裂过程、仪器观测数据资料,进一步考虑局部场地效应快速计算获得了此次地震的地震动强度图结果.震后快速产出的地震动强度图科技产品能够为震后的应急反应决策和地震应急评估提供科技支撑.

Voltage-controlled magnetic skyrmions have attracted special attention because they satisfy the requirements for well-controlled high-efficiency and energy saving for future skyrmion-based neuron device applications.In this work,we pro-pose a compact leak
The energy deposition and electrothermal behavior of SiC metal-oxide-semiconductor field-effect transistor (MOS-FET) under heavy ion radiation are investigated based on Monte Carlo method and TCAD numerical simulation.The Monte Carlo simulation results sh
A three-dimensional (3D) silicon-carbide (SiC) trench metal-oxide-semiconductor field-effect transistor (MOSFET)with a heterojunction diode (HJD-TMOS) is proposed and studied in this work.The SiC MOSFET is characterized by an HJD which is partially embedd
We fabricated a set of symmetric gate-recess devices with gate length of 70 nm.We kept the source-to-drain spacing(LsD) unchanged,and obtained a group of devices with gate-recess length (Lrecess) from 0.4 μm to 0.8 μm through process improvement.In order
This paper details the design and simulation of a novel low-loss four-bit reconfigurable bandpass filter that integrates microelectromechanical system (MEMS) switches and comb resonators.A T-shaped reconfigurable resonator is reconfig-ured in a \'one re
With the development of network science,the coupling between networks has become the focus of complex network research.However,previous studies mainly focused on the coupling between nodes,while ignored the coupling between edges.We propose a novel cascad
Opinion dynamics models based on the multi-agent method commonly assume that interactions between individuals in a social network result in changes in their opinions.However,formation of public opinion in a social network is a macro-scopic statistical res
To enhance device performance and reduce fabrication cost,a series of electron transporting material (ETM)-free perovskite solar cells (PSCs) is developed by TCAD Atlas.The accuracy of the physical mode of PSCs is verified,due to the simulations of PEDOT:
2022年1月8日,青海门源地区发生MS6.9地震,本文利用CAP方法反演了主震震源机制解和震源深度.结果显示,断层节面Ⅰ:走向191°/倾角62°/滑动角173°,节面Ⅱ:走向284°/倾角82°/滑动角21°.此次地震为走滑型地震,最佳矩心震源深度约3 km,矩震级为MW6.7.结合震源机制解和定位结果分析认为,节面Ⅱ可能为实际破裂面,本次地震发生在冷龙岭断裂和托莱山断裂的交汇部位,本次地震与2016年和1986年2次M6.4地震震源机制解不同,显示出该区域复杂的构造背景.
据中国地震台网中心测定,北京时间2022年1月8日01时45分,中国青海省海北州门源县发生了M6.9地震,震中位于( 37.77°N, 101.26°E),震源深度为10 km.这是2022年中国大陆第一个接近7级的强震.距离此次地震震中40 km以东,2016年曾发生过门源M6.4地震;且东北部在1927年还发生过甘肃古浪M8地震.
