| 摘 要： | 本文描述了近几年来我们首次研制成功的３种类型的水中荧光计系统及其应用测量结果：１．用于水体混合扩散实验研究的水中荧光计，对罗丹明Ｂ浓度测量范围为１×１０－６～１×１０－１０ｇ／ｃｍ３；２．拖曳荧光计系统，能在２～８０ｍ水深内进行水平拖曳平稳地工作，拖曳速度为０～８ｋｎ，除检测罗丹明Ｂ外，还可检测无机悬浮物质的含量，检测范围为２～２０００ｍｇ／ｄｍ３；３．用于测量海中浮游植物体内叶绿素ａ浓度的水中荧光计，测量范围为１×１０－６～１×１０－９ｇ／ｃｍ３。用荧光法测量海中物质是近代新发展的一种简便、快速、灵敏度高、用途极其广泛的测量技术，有着重要的应用价值。

| Abstract: | In order to shorten the times of through-running train stayed on stations in the problem of fetching and delivering waggons of through-running train on treelike railway individual line,delivering and waiting for fetching waggons mode,fetching waggons after delivering waggons mode are studied.Two simple and fast algorithms for the problem of fetching and delivering waggons of throughrunning train on tree-like railway individual line are given by building the models of graph and scheduling theory. |
