基于商密算法的视频终端安全接入系统的研究与实现

在电网视频监控系统不断发展的同时,视频终端接入监控系统时的安全问题也在不断突出,信息泄漏、数据篡改以及恶意攻击等问题严重威胁着电网的安全。本文基于电网视频监控系统的应用现状以及安全风险,结合电力安全防护的要求,设计一种基于商密算法的视频终端安全接入系统,可实现电力视频终端的安全接入。最后通过实验测试分析并验证了该系统能够满足电力视频监控的安全防护要求。

Study on relationship between deep and shallow structures along north boundary fault of Yanqing-Fanshan basin

Based on the results of surface geology, shallow and deep seismic survey, features of micro-earthquake activity along the north boundary fault of Yanqing-Fanshan sub-basin and their relationship with the surface active faults and the deep-seated crustal structure are analyzed using the recordings from the high-resolution digital seismic network. The focal mechanism solutions of micro-earthquakes, whose locations are precisely determined by the seismic network, have confirmed the structural characteristics to be the rotational planar normal fault and demon-strated the surface traces of the north boundary fault of Yanqing-Fanshan sub-basin. By using the digital recordings of earthquakes with the high resolutions and analyzing the mechanism solutions, our study has revealed the rela-tionship between the geological phenomena in the shallow and deep structures in Yanqing-Huailai basin and the transition features from the brittle to ductile deformation with the crustal depth.

产教融合背景下《材料专业技能拓展训练》课程教学改革

技能拓展训练是材料专业的一门实践课程,一方面提高了企业参与高校教学的深度,另一方面,开拓了学生的视野和解决复杂工程问题的能力。加快推进和完善材料专业技能拓展训练已成为当前推进产教融合的重要推手。本文结合台州学院《材料专业技能拓展训练》在建设过程中的不足之处和产教融合背景下的课程教学改革措施,提出通过优化实验内容、优选企业案例、开展企业现场教学,以及更新实践评定办法等措施,进一步切实提高学生工程实践能力。
