Based on the key tree and the Chinese remainder theorem, a leveled group key management scheme in wireless networks is proposed. An efficient stateless and leveled group key management scheme focusing on the revocations of wireless nodes is also presented. The security, flexibility, and adaptability of these two schemes in wireless networks are analyzed.

针对无线网络的特点建立了一种基于密钥树和中国剩余定理的分级群组密钥管理方案，针对无线节点容易被捕获的问题提出了一种能够有效解决密钥撤销的无状态分级群组密钥管理方案，并且着重分析了这两种方案在无线网络中的安全性、可扩展性和适用性。

When a shortest path between nodes is searched with this algorithm,a lot of repetitional computations are involved,so that the efficiency is low.

借助于矩阵算法来求最短路问题比较有效[1]，但当节点比较多时，计算的矩阵多，重复计算量大，降低了计算效率[2，3]。

The data layout of parallel storage system was completed by using rebalancing operations of simulation data repetitiously so as to make the nodes extension of the system more easily.

它通过多次模拟数据重均衡操作来完成并行存储系统的数据分布，从而使得系统更易于节点扩展。

Instead of simply requiring a distance between nodes on the graph representing the road network, a set of travel times are also required for every time interval defined.

不是只要求标示在图表上网点间的距离，而是同样需要一套为详细说明每一时间间隔而定的行车次数。

At their heart, scenegraphs are nothing more than a graph of nodes representing the spatial layout of a 3D scene while encapsulating primitive graphic characteristics in objects.

场景图不过是使用一些节点来表达3D 场景中的空间物体（ spatial layout ？）的图，同时还以对象的形式封装了图形基元（ primitive graphic characteristics ？）。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。
