可戳的

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。

Second, other members believe as follows: A requirement for a document to be legalized, visaed, certified or similar will be satisfied by any signature, mark, stamp or label on such document that on its face appears to satisfy the above condition.

第二，其他成员的意见如下：诸如单据必须认证、签证、证实或类似的要求，可由表面看来满足了上述条件的单据上的任何签字、标记、印戳或标签来满足。

They allow that the backend server could delegate the reader to identify the tag information. But the Fouladgar and Afifi's SiDES protocol will suffer from the replay attack, forgery attack, Denial-of-Service attack and fail to achieve the forward security. Although Lin's protocol uses timestamp to control the delegation, it does not keep forward security property under the same time frame.

在2007年，Fouladgar和Afifi首先提出了离线式SiDES协定，接著Lin也提出了TCD-RP协定，可让后端伺服器可以授权读取器辨识标签的资讯，但Fouladgar和Afifi的SiDES定理，会遭受重送攻击、伪造攻击、阻断服务攻击以及不具有向前安全性的特性；而Lin的协定虽然使用时戳来做授权的控制，但在相同的时间区段下运作，并不具有向前安全性的特性。

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。
