As necessitated by the maintenance of state security , a state security organ may , when necessary and in accordance with the relevant provisions of the state , have priority in use of any means of transport or communication , site or building belonging to any organ , organization , enterprise , institution or individual , and shall make a timely return after the use and pay an appropriate fee , and , in case of any damage or loss , shall make compensation therefor 国家安全机关为维护国家安全的需要，必要时，按照国家有关规定，可以优先使用机关、团体、企业事业组织和个人的交通工具、通信工具、场地和建筑物，用后应当及时归还，并支付适当费用；造成损失的，应当赔偿。
Cargo , ship ' s materials and stores , or any of them , necessarily used for fuel for the common safety at a time of peril shall be allowed as general average , but when such an allowance is made for the cost of ship ' s materials and stores the general average shall be credited with the estimated cost of the fuel which would otherwise have been consumed in prosecuting the intended voyage 在遭遇危险时，为了共同安全的需要，用作燃料的货物、船用材料和物料，应认作共同海损，但船用材料和物料费用受到补偿时，为完成原定航程本应消耗的燃料的估计费用，应从共同海损中扣除。

This thesis introduced a new type of network architecture - - service unit based architecture , mainly analysed the characteristics , node modes , definition and the services provided by the service unit based architecture . the micro communication element architecture was analysed too . the communications based on virtual circuit not only guarantee qos but also support the security preferably of the network 基于虚电路的通信方式比基于数据报的通信方式能更好地保证网络的qos 、更好地支持网络安全的需要,所以在微通信元系统架构中采用了虚电路的通信方式,文中对虚电路进行了深入细致的分析和研究。
Under china enterprise development environment , we try to find solution scheme that adapt to our country after carefully studied information security of enterprise , of course the solution must based need to information security of enterprise . we set up security system in order to protect information assaulted and destroyed , that the studied of the intrusion detection system is key 本论文以我国企业发展为背景，根据企业对信息安全的需要，进行了企业的信息安全的研究，尝试性地探索出适应我国企业的安全技术解决方案，并以入侵检测技术的研究为重点，探讨在企业内部建立一套安全的信息保障体系，防止企业内、外部的有意或无意的攻击和破坏。
Firstly , the internal environment in the asia - pacific area determines that other security patterns do n ' t suit the need of the protection of the national and regional security for the countries hi this area , that is , balance - of - power security . collective security and common security . secondly , the great changes of the external environment in the asia - pacific area after the cold war made countries hi this area from decentralization to cooperation , so the security pattern of " cooperative security " became the rational choice for countries in this area 其次，从理论的视角看：第一，从系统?环境的角度考虑，亚太地区的内部环境决定了历史上和现实中存在的几种安全模式如均势安全、集体安全和共同安全模式不符合冷战后亚太国家维护本地区及国家安全的需要；冷战后亚太地区外部环境发生的巨大的变化使亚太各国由分散走向合作，使亚太各国选择“合作安全”模式来保障地区安全及国家安全成为理性、成为必然；第二，从国际合作的理论视角考虑， “合作安全”是增进冷战后亚太地区国家客观共同利益的有效途径。
Persons can visit on net conventionally through net but also can attack , stole messages or destroy systems on net the electronic business is increasing , some messages are protected by the way of encryption , but in traditional method there is something trouble that the messages transported on net have the same key to encrypt data and decrypt data such as des . in this case how to distributed a secret key securely on net has n ' t a perfect solutioa while the technology of pki can solve it through distributing certificates and provide the vary net applications confidentiality , integrity , authentication and non - repudiation 随着internet以及电子商务的发展，人们对信息安全的需要越来越迫切，于是出现了依靠加密的手段保护敏感信息在网络上的安全，虽然在?定的程度上杜绝了网上传输信息的被窃取和破坏，但是依靠传统的加密手段本身就存在着安全隐患，比如说des对称加密算法)由于加密和解密采取了同一的密钥，怎样安全的分发密钥就成了难以解决的问题。
Ship ' s materials and stores , or any of them , necessarily burnt for fuel for the common safety at a time of peril , shall be admitted as general average , when and only when an ample supply of fuel had been provided ; but the estimated quantity of fuel that would have been consumed , calculated at the price current at the ship ' s last port of departure at the date of her leaving , shall be credited to the general average 在遭遇危险时，为了共同安全的需要，当作燃料烧掉的船用材料、物料应认作共同海损，但只限于船上原以备足燃料的情况；其本应消耗的燃料的估计数量，应按该船舶驶离上一港口当日在该港口的价格计价，从共同海损中扣除。
