地震站网全流程一体化监控平台是基于微服务框架,应用数据库、通信、并行计算等传统信息技术,结合新兴的云计算、大数据进行建设的信息服务平台。该平台采用Hadoop分布式处理方案,应用Spring Cloud框架搭建,进行Docker容器封装,以标准RESTful API作为服务接口的微服务架构,实现了各应用服务模块之间的高内聚、低耦合及灵活、可扩展的特性,最终实现对地震台站运行的实时监测、高效运维和一体化管理。  相似文献   

基于1973年炉霍MS7.6地震震后跨断层变形的地震轮回特征     

杜方  吴江  梁明剑 《地震地磁观测与研究》2021,42(z1):131-135

1 研究背景 地震活动断层不同区段和时段均具有不同的力学特性,主要是表现在活动断层上发生地震的断层段所呈现的震前、同震、震后和震间4个时域范围内的滑动行为.换言之,地震活动断层的滑动行为分为震前、同震、震后和震间4个滑动阶段.通过研究活动断层地震破裂段震前、同震、震后和震间滑动,可深入破解沿活动断层破裂段的应力、应变的积累和释放的时空信息变化(Reilinger et al,1999;Yagi et al,2001;Ozawa et al,2004).  相似文献

实测了云南西部兰坪盆地东部下白垩统下部景星组的五茂林剖面,建立了曲流河、三角洲和湖泊3种沉积序列,其中三角洲序列在云南下白垩统中属首次建立。分析了粗碎屑岩的组成,将该剖面上出露的砾岩分成4类。早白垩世时兰坪盆地属丹那沙林-高黎贡弧的弧后盆地,景星组自下而上为曲流河沉积、三角洲沉积和湖泊沉积,且随湖侵发生,湖泊向西扩大。  相似文献   

A complicated solar eruption event on 2003 October 26     

Zongjun Ning  M. D. Ding  K. P. Qiu  H. Li  Y. N. Su  C. Fang 《Astrophysics and Space Science》2008,315(1-4):45-51

We present multi-wavelength observations of a complicated solar eruption event to associate with an X1.2 flare and a Coronal Mass Ejection (CME) on 2003 October 26. The soft X-ray profile shows a possibility for occurrence of two flares with peaks around 06:20 and 07:00 UT. According to our observations, there are many evidences to show that they are corresponding to two energy releases. The first one produces type II, type III, moving type IV continua, a decimetric burst (DCIM) and strong emissions at Hα, 195 and 1600 Å; While the second energy release only produces a group of RS-III bursts, DCIM and Hα emissions. It appears that the first energy release is associated with a CME, while the second CME is quiet. Such observational difference between two energy releases is found indicating two magnetic reconnection processes occurrence with different plasma situation.  相似文献

Solar Radio Spikes in 2.6 – 3.8 GHz during the 13 December 2006 Event     

S. J. Wang  Y. H. Yan  Y. Y. Liu  Q. J. Fu  B. L. Tan  Y. Zhang 《Solar physics》2008,253(1-2):133-141

On 13 December 2006, some unusual radio bursts in the range 2.6?–?3.8 GHz were observed during an X3.4 flare/CME event from 02:30 to 04:30 UT in active region NOAA 10930 (S06W27) with the digital spectrometers of the National Astronomical Observatories of China (NAOC). During this event many spikes were detected with the high temporal resolution of 8 ms and high frequency resolution of 10 MHz. Many of them were found to have complex structures associated with other radio burst types. The new observational features may reflect certain emission signatures of the electron acceleration site. In this paper, we present the results of the analysis of the new observational features of the complex spikes. According to the observed properties of the spikes, we identify five classes. Their observational parameters, such as duration, bandwidth, and relative bandwidth, were determined. Most spikes had negative polarization, but spikes with positive polarization were observed during a short time interval and were identified as a separate class. Based on the analysis of observations with Hinode/SOT (Solar Optical Telescope) we suggest that the sources of the spikes with opposite polarizations were different. Combined observations of spikes and fiber bursts are used to estimate the magnetic field strength in the source.  相似文献   

Swift时代伽马暴的观测及研究进展   总被引：1，自引：0，他引：1

Swift卫星从2004年11月20日升空开始运转到现在已有2年多时间.到目前为止,它-共观测到了200多个伽马暴及其余辉现象.由于Swift观测到了早期X射线余辉、短暴余辉和高红移伽马暴等新的重要现象,伽马暴研究进入了新的时代.该文首先对伽马暴的研究历史做简短回顾,然后简要介绍伽马暴的物理图像和Swift卫星的构成及特点,最后全面评述Swift的观测成就及由此引起的理论挑战.  相似文献   

东南极格罗夫山地区新生代冰碛岩(物)中孢粉的发现及其意义   总被引：2，自引：0，他引：2

文章报道了东南极格罗夫山地区蓝冰表面碎石带新生代冰碛岩(物)漂砾中微体古生物化石的分析结果及其意义。研究发现这些冰碛物(岩)内含有少量孢粉,而未见硅藻及其他微体化石。孢粉以裸子植物花粉和蕨类植物孢子为主、被子植物花粉含量相对稀少为特征。值得注意的是,在所分析的4个样品中,均发现至今在南半球仍有分布的特有属假山毛榉(Nothofagus)花粉,由于该属花粉及大植物化石曾发现于横跨南极山脉上新的天狼星群(SiriusGroup)中,它的存在反映当时古气候温暖湿润。在样品S1507和S1509中发现蒿属(Artemisia)花粉,其出现所代表的时代推测为新近纪,很可能为上新世。格罗夫山地区冰碛物中的这一孢粉特征可能反映了南极地区上新世曾经发生过较大规模的气候变暖和冰川退缩事件。  相似文献
