The last but not least, it is also owning to the rapid development in computer science and information technology. Such as, some computational task, which previously must be executed by using super-computer, now can be carried out by personal computer, and at the same time, the network speed and band width of data bus and input/output equipment have increased several times. In addition, the improvement of the high quality graphic displaying is available. All these provide strong support for cryoEM high-resolution reconstruction study.

目前，在低电子剂量的情况下，冷冻电镜照片可以记录到3-4 〓的信息，使用冷冻电子显微镜进行高分辨三维重构工作，已经获得6.5-8〓高分辨率水平的结果，可以分辨出蛋白质的α螺旋、识别出蛋白质的β折叠等蛋白质二级结构；其次是，三维重构算法效能的不断提高，使得对二十面体取向和中心参数计算的可靠性大大提高；再次是，由于计算机和信息技术迅猛发展，例如，以往需要使用大型计算机的计算任务已经可以被一般的个人电脑完成，网络速度、数据总线和硬盘等I／O设备的带宽成倍增长，以及图像显示能力的提高都为冷冻电子显微镜高分辨三维重构技术提供了强有力的支持。

Nowadays, in the low electron dose condition, the information about 3-4〓 can be recorded on the cryoEM micrograph, and the high-resolution reconstruction using the cryoEM has reached 6. 5-8〓 levels. The reconstruction can reveal the protein α helical and recognise β fold secondary structure. Secondly, it is due to the development in 3D reconstruction method, which can be more efficient to determine the orientation and center parameters. The last but not least, it is also owning to the rapid development in computer science and information technology. Such as, some computational task, which previously must be executed by using super-computer, now can be carried out by personal computer, and at the same time, the network speed and band width of data bus and input/output equipment have increased several times.

The algorithm runs on the sink node and the connected dominating set educed from the algorithm forms the virtual backbone of the network. Because the algorithm gets the global information and the information is general, the size of the connected dominating set got from the centralized heuristic algorithm is smaller than that of distributed heuristic algorithm.

本文算法在中心控制或管理节点上运行，求得的连通支配集构成无线传感器网络的虚拟骨干网，并且由于算法采用网络的全局信息，获得的信息量较为全面，所以求得的连通支配集的规模相对于分布式算法更小。

Net-centric warfare system is a distributed real-time system that has characteristics of independence, heterogeneousness, adaptability and synergetic, it is a great challenge to traditional distributed real-time computation.

在该网络中，各作战单元将在高速和连续的基础上共享大量的关键信息，将会大大提高海军作战的反应速度、精度和有效性。网络中心战系统是一个分布式实时系统，具有动态性、异构性、适应性和协同性，对传统的分布实时计算技术提出了巨大的挑战。
