    • An exhaust gas purifying catalyst for oxidizing HC and CO and for reducing NOx is provided, which comprises at least one oxide of rare earth element, rhodium, and at least one of platinum and palladium loaded on alumina grains. The major amount of rhodium is dispersed on the oxide of rare earth element. Thus, the rhodium solidification into the alumina grains is prevented. Further, when cerium oxide accompanying lanthanum oxide, neodymium oxide or a mixture thereof is used as the oxide of rare earth element, the sintering of cerium oxide or palladium at a high temperature is suppressed since it forms a complex oxide with lanthanum oxide, neodymium oxide or a mixture thereof. Additionally, when stabilized alumina grains in which a rare earth element and an alkali earth element are present in a solid solution state are used, the deterioration of NOx purifying activity of the catalyst at a high temperature is suppressed. The exhaust gas purifying catalyst of this invention has high durability as well as high activity at a high temperature.
    • 提供一种用于氧化HC和CO并用于还原NOx的废气净化催化剂,其包含至少一种稀土元素氧化物,铑,以及负载在氧化铝颗粒上的铂和钯中的至少一种。 铑的主要量分散在稀土元素的氧化物上。 因此,防止了铑固化成氧化铝颗粒。 此外,当使用伴随氧化镧,氧化钕或其混合物的氧化铈作为稀土元素的氧化物时,氧化铈或钯在高温下的烧结被抑制,因为它与氧化镧,氧化钕形成复合氧化物 或其混合物。 此外,当使用其中以固溶状态存在稀土元素和碱土金属元素的稳定的氧化铝颗粒时,抑制了催化剂在高温下的NOx净化活性的劣化。 本发明的废气净化催化剂在高温下具有高耐久性和高活性。

    • Mobile nodes are allowed to move around within an intermittent communication environment. A mobile node wirelessly communicates with an access node when approaching the access node, and stores data. The access node stores an action history for each mobile node, and generates a forwarder list in association with a destination node, based on action histories of the mobile nodes. The forwarder list stores one or more identifies each identifying a first mobile node in the order of an arrival probability indicating a probability that the first mobile node succeeds in delivering the data to the destination node. The access node selects second mobile nodes that are to carry the data to the destination node, based on the forwarder list, and transfers the data to one of the second mobile nodes when a communication link is established between the access node and the one of the second mobile nodes.
    • 允许移动节点在间歇通信环境内移动。 移动节点在接近接入节点时与接入节点进行无线通信,并存储数据。 访问节点存储每个移动节点的动作历史,并且基于移动节点的动作历史与目的地节点相关联地生成转发器列表。 转发器列表按照指示第一移动节点成功将数据传送到目的地节点的概率的到达概率的顺序存储一个或多个标识每个标识第一移动节点的标识。 接入节点基于转发器列表选择将数据携带到目的节点的第二移动节点,并且当在接入节点和接入节点之间建立通信链路时,将数据传送到第二移动节点之一 第二个移动节点。
