安全通信

Space environment threaten orbited spacecraft' s safe functioning and astronaut' s health, influence greatly communication depended on based-space way, airmanship orientation, military detection, aim identification, weather observation and source exploration and so on by all sorts of function (magnetic storm, solar proton event and so on).

空间环境通过各种效应(如磁暴、太阳质子事件等)对在轨航天器的安全运行及航天员的健康构成了严重的威胁，对依赖于天基手段的通信、导航定位、军事侦察、目标识别、气象观测、资源勘探等等均有重要影响。

Finally, applications of the anomalous propagation of microwave in tropospheric ducts are discussed: in connection with concrete radar parameters, effects of ducts on radar range and detection performance are discussed, the results obtained are of great value for the overall design of radar systems; by use of the interference standards of ITU-R, the co-ordination area of satellite earth-station under tropospheric ducts environment is studied ; by explaining the relationship between evaporation duct and advection fog, a new way to forecast sea advection fog from evaporation duct is provided.

最后讨论了对流层大气波导环境下电波异常传播特性的应用：结合具体的雷达系统参数，模拟计算了大气波导对雷达作用距离及发现概率的影响，对雷达系统的总体设计具有重要的参考价值；对表面大气波导环境下的卫星地球站通信协调区域进行了确定，从理论上很好地给出了协调距离量级的概念，为卫星地球站与地面微波站之间的协调提供了依据和参考；分析了利用海面蒸发波导来快速预测平流海雾的新方法，完善了平流海雾的预报方法，对海上安全作业和生产具有重要的意义。

Communication and the anticipative management of industrial and economic change.

与安全、环境、社会对话、通信、工业和经济变化的预期管理。

In every policy, there must be some security authentication information,such as one policy Authorizer, one Licensee, one TimeStamp, one LifeTime and a digital Signature, and some policy management information:At last, this paper designs and implements a HywaveGuard models instance based on Windows OS.

每个策略都有策略发布者，接受者的证书，策略制定的时间戳及有效期，同时还要附上发布者的数字签名，这些信息用于保证策略的安全验证；每个策略还可包含策略管理命令及策略内容，这些信息用于保证有效的策略管理与节点间通信。最后，针对当前网络的实际情况，本文在Windows系统平台上设计与实现了HywaveGuard防火墙模型的一个实例。

With the development of computer,communication and automatization technology,more and more importance is attached to synthesis safety control technology.

随着计算机、通信、自动化技术的迅速发展，综合性的安全控制技术将得到越来越多的重视。

With the development of computer,communication and automatization technology,synthesis safety control technology are regarded.

随着计算机、通信、自动化技术的迅速发展，综合性的安全控制技术将得到越来越多的重视。

When the number of ship stations which make calls is far more larger than the number of users which the system can allow to handle, the weak channel control ability will lead to network congestion , so the baud rate and the communication protocol of current IFCNSS can not adapt a large-scale fishery busywork.

而发起呼叫的船台数远大于系统能容许处理的用户量时，较弱的信道控制能力必将导致网络的阻塞，所以目前"安全通信网"中的传输速率和通信协议不能适应大规模渔场作业。

Card" at the national wire and cable industry and the supervision and checking of the previous, stable and reliable quality, with a pass rate of 100 percent, and achieved a "Famous Chinese Trademark" and "national Mianjian products" and "trust the quality of products","State IMPACT Fuyou focus on protection products ", etc., and the honorary title of" ISO9001 certification,"" National industrial production license "and" signs mine safety certification "," Fire product safety certification "," 3C certification.

牌&电线电缆在国家和行业的历次监督抽查中，质量稳定可靠、合格率 100%，并取得了&中国驰名商标&、&国家免检产品&、&全国质量信得过产品&、&国家打假扶优重点保护产品&，等荣誉称号和& ISO9001 认证&、&全国工业品生产许可证&、&煤矿用通信电缆安全标志认证&、&消防产品安全认证&、& 3C 认证等。

When two communicants and an adversary obtain correlated information through independent binary symmetric channels from a random source, and the adversary's channel is noisier than those of communicants, an authentication scheme which uses the correlated information between the two communicants is proposed based on the coding theory to make possible information theoretic secret key agreement against active attacks.

在无条件安全密钥协商中，假定通信双方通过相互独立的无记忆二元对称信道来接收二元对称信源所传送的信息作为初始信息，在这种条件下，本文提出了一种利用他们之间的初始相关信息对公共信道上的消息进行认证的具体方案，从而使得无条件安全密钥协商具有抗主动攻击的能力。

Digital certificates are used by the SSL security protocol to create a secure "pipe" between two parties that seek confidential communication.

数字证书由SSL安全协议用于在寻求保密通信的两方之间生成安全&管道&。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
