摘要：In the conceptual stage the function design process is realized by the computer aided application. After surveying on the function specification methods and the function modeling, a computer aided function design environment is analyzed. Subsequently based on a module library and principle catalogue, a solution finding process as a part of conceptual design is proposed for a creative design. In addition, a search algorithm to find the solution of adaptable function structure is also discussed. The concepts proposed in this paper can support the subsequent design stages, especially simulation for checking the function structure defects.

摘要：本文通过周密的设计和反复实验,分别从取样时间、取样位置和取样体积三方面进行了分析,并且从去离子水、地表水和污水进行对比实验数据中得出一个取样的最佳方案,从而对现有碘量法测定溶解氧的分析提出了修改意见。

摘要：防空地下室密闭性好,通风条件差,平时发生火灾时存在烟气蔓延速度快、疏散难度大、外部救援难度大等消防隐患。该文对防爆波活门位置分类及特点进行分析,探讨防空地下室防爆波活门位置对平时消防设计的影响,并提出相应的解决策略,比选出最优方案。
