With the wide application of electronic hardware in aircraft such as air-to-ground com-munication,satellite communication,positioning system and so on,aircraft hardware is facing great secure pressure.Focusing on the secure problem of aircraft hardware,this paper proposes a super-visory control architecture based on secure System-on-a-Chip (SoC) system.The proposed architec-ture is attack-immune and trustworthy,which can support trusted escrow application and Dynamic Integrity Measurement (DIM) without interference.This architecture is characterized by a Trusted Monitoring System (TMS) hardware isolated from the Main Processor System (MPS),a secure access channel from TMS to the running memory of the MPS,and the channel is unidirectional.Based on this architecture,the DIM program running on TMS is used to measure and call the Lightweight Measurement Agent (LMA) program running on MPS.By this method,the Operating System (OS) kernel,key software and data of the MPS can be dynamically measured without dis-turbance,which makes it difficult for adversaries to attack through software.Besides,this architec-ture has been fully verified on FPGA prototype system.Compared with the existing systems,our architecture achieves higher security and is more efficient on DIM,which can fully supervise the running of application and aircraft hardware OS.

干旱管理属于政府的公共管理职责,实现对干旱灾害的高效管理,首先需要提高政府及所属相关部门、机构的整体管理效能。强调整体效能是因为实施科学的干旱管理需要各级政府及众多的政府部门和机构的协同,因此清晰的职责和有效的协调机制是十分重要的。提高政府干旱管理的整体效能,需要更合理的机构组织设置,需要更具体、更明确的责任确定和问责制度,需要更严格、周密的行政程序。

后坑垅水库大坝采用C15细石混凝土砌石重力坝,左岸地形较陡,在顶部呈一平台,地勘钻孔揭示左岸坝肩存在较深厚的强风化岩层,且延伸较长。在设计中坝肩接头坝段利用强风化岩层作为坝肩持力层,同时将帷幕灌浆向左岸进行延伸,即解决了坝肩绕坝渗漏问题,又减少了坝基开挖及坝体砌筑量,从而达到节省工程投资的目的。接头坝段侧向抗滑稳定分析中采用刚体极限平衡法进行分析,各工况下均能满足规范要求。
