    • The deterioration of reinforced concrete structures by galvanic corrosion adversely affects roads, bridges, parking garages and buildings that use reinforcing steel in their construction. Galvanic cathodic protection is typically provided for such reinforced concrete structures using embedded sacrificial anodes, such as zinc, aluminum, and alloys thereof. Disclosed herein is an anode assembly (10) for cathodic protection of a reinforced concrete structure. The assembly comprises at least one sacrificial anode member (12). The anode member is covered with an ionically-conductive covering material (14) into which is bound an electrochemical activating agent at least partly covering the sacrificial anode member. One side (26) of the ionically-conductive covering material is configured to conform closely to a steel reinforcing bar. The conforming side has a non-conductive barrier (16) as an integral part of the covering material. Electrical connectivity is established between the anode member and a ferrous reinforcing bar (20) using conductive wires (18).
    • 钢筋混凝土结构由电镀腐蚀的恶化对施工中使用钢筋的道路,桥梁,停车库和建筑物造成不利影响。 通常为使用嵌入式牺牲阳极(例如锌,铝及其合金)的这种钢筋混凝土结构提供电阴极保护。 本文公开了一种用于钢筋混凝土结构的阴极保护的阳极组件(10)。 组件包括至少一个牺牲阳极部件(12)。 阳极构件被离子导电覆盖材料(14)覆盖,其中结合有至少部分覆盖牺牲阳极构件的电化学活化剂。 离子导电覆盖材料的一侧(26)被配置成紧密地配合钢筋。 配合侧具有作为覆盖材料的组成部分的非导电屏障(16)。 使用导线(18)在阳极构件和铁质钢筋(20)之间建立电连接。

    • In asymmetric cryptography, initially-set public key and private keys are updated as a function of the chosen prime number pair, a host sending an updated public key exponent and a unique prime-pair key associated with the chosen prime number pair to the client, the client using the unique prime-pair key to look-up and retrieve the chosen prime number pair and determine the updated public key and the updated private key as a function of the retrieved chosen prime number pair, the host and the client encrypting and decrypting exchanged messages with the updated public key and the updated private key without executing another handshake. In one aspect, a large even integer is used by host and client to generate a plurality of prime number pairs, and the unique prime-pair key may be a distance between each prime number of an associated prime number pair.
    • 在非对称密码学中,初始设置的公钥和私有密钥根据所选择的素数对进行更新,主机向客户端发送与所选择的素数对相关联的更新的公开密钥指数和唯一的素数对密钥, 客户端使用唯一的素数对密钥来查找和检索所选择的素数对,并根据检索到的所选素数对确定更新的公钥和更新的私钥,主机和客户端加密和解密 使用更新的公钥和更新的私钥交换消息,而不执行另一个握手。 在一个方面,主机和客户端使用大的偶数整数来生成多个素数对,并且唯一的素数对密钥可以是相关联素数对的每个素数之间的距离。
