加强网络与资源能力建设的思考

信息内容的数字化、网络化进程正在从根本上变革科技信息(情报)机构的信息服务理念、手段以及方式方法,从偏重信息资源能力转变为同时加强网络和资源"两种能力"建设,已经成为新形势下稳定提升科技信息(情报)机构的服务质量水平的重要保障。本文对该命题作了比较深入细致的理性思考,提出了有针对性的重点工作任务和推进措施。

网络安全技术路径的解释重塑与分类适用

在网络安全保障体系和能力建设的构建过程中,网络安全技术关系重大,但存在基础理念解释模糊以及不同场景下网络安全技术路径适用失衡的问题。对于网络安全技术路径的理念分析,应该在总结历史经验的基础上抛弃技术万能论,而是在秉持相对安全的理念下,坚持保障网络安全技术的效率,追求互利共赢的技术合作。对于不同的适用场景,网络安全技术需要进行有针对性的调整,在网络运行安全制度中构建规范体系并划分层级,加强技术审查,在网络信息安全制度中从国家主管机关和网络服务商两方面着手进行完善,并在网络空间命运共同体的背景下,消除技术交流壁垒、统一技术交换标准、畅通技术信息交流通道,实现对网络空间的全方位保护。

Research on Safety and Stability of Regional Power Grids to the Year 2020

The safety and stability study on Northeast, North, East, Northwest and Central China power grids had been carried out, which provided technical supports to planning design of regional power grids. By analyzing safety and stability under severe faults in regional power grids, revealed weaknesses on power grid configurations and measures for preventing from loss of stability were presented. In comparison of various schemes of power system safety and stability among parts of power grids, more than two recommended schemes can be chosen as reference in planning design for regional power grids. Considering the safety and stability control measures necessary for each power grids, it is believed the trunk networks of all power grids can fulfill the third criteria of Guideline for Power System Safety and Stability, while the weakness and predominated hydropower may deteriorate safety and stability of power grids. The power grid shall be regulated in line with the variation of boundary conditions.
