可用带宽度量系统中的若干基本问题

结合过去3年中设计、开发和部署BNeck系统的经验，分析了13个可用带宽度量系统的工作原理及软件实现，并在此基础上总结了可用带宽度量系统中存在的若干基本问题，对这些问题的研究，不仅有利设计和开发出高效、准确的度量系统，也有利于推动网络管理和视频通信等多个相关领域的共同发展。

Method for calculating ecological water storage and ecological water requirement of marsh

As one of the most typical wetlands, marsh plays an important role in hydrological and economic aspects, especially in keeping biological diversity. In this study, the definition and connotation of the ecological water storage of marsh is discussed for the first time, and its distinction and relationship with ecological water requirement are also analyzed. Furthermore, the gist and method of calculating ecological water storage and ecological water requirement have been provided, and Momoge wetland has been given as an example of calculation of the two variables. Ecological water use of marsh can be ascertained according to ecological water storage and ecological water requirement. For reasonably spatial and temporal variation of water storage and rational water resources planning, the suitable quantity of water supply to marsh can be calculated according to the hydrological conditions, ecological demand and actual water resources.
