The contribution of water concentration on the growth of carbon nanotubes was investigated. Scanning electron microscopy results showed that the grown CNTs in CH4/H2 gas mixure had chain-shaped structure and the diameter was about 40—90nm. With the addition of proper amount of water, the diameter of CNTs became uniform, and the surfaces of nanotubes were fully covered with nano-sized node-like structures. When more water was added, branched carbon nanotubes were synthesized.

Investigation and evaluation of soil and water resources in Minqin Oasis indicate that the proportion of grain crop, cash crop and grass is 36.94:45.16:17.90 for 2005. And a comparison with that for 1991 indicates that land use structure is developing towards rational proportion of grain crop, cash crop and grass; and harmony among agriculture, stockbreeding and forest. The main limiting factors of land resources are water, soil quality, salinity and fertility, and there is about 3.9218×10^8 m^3 water deficit per year in Minqin Oasis.

通过水土资源现状的分析评价，发现2005年民勤绿洲粮经草比例为36.94：45.16：17.90，与1991年相比，土地利用格局正向粮经草比例优化和农林牧协调方向发展；民勤绿洲土地资源的限制性因素主要为水分、土质、盐碱和肥力；对水资源现状分析发现民勤绿洲年缺水量达3.9218亿立方公尺。

Since the installation of fire safety is not a part of a building structure and the seismic building design code does not include fire water pipings, the design of them in Taiwan does usually not consider the seismic effect. This study first collected and summarized the relevant seismic design codes and fire control standards from U.S., Japan, China and Taiwan to understand the internationally adopted methods for seismic from designs of fire water pipings. This study also gathered engineering cases and photographs of the installation of the shock resistance hangers of fire water pipings in high technology factory buildings. Then, this study presented a proposal for seismic design principles. we hope this can attract attentions from government authorities and the fire safety business sector and to rise concerns of the seismic design of fire safety installation; and therefore set up a clear and practical criterion for the engineers and finally reduce the damage of post earthquake fires.

由於消防安全设备向来都是归属於非结构物，国内一般在进行结构设计时并未将消防管路纳入耐震设计的范畴内，本研究系针对建筑物内消防管路的耐震设计为议题，搜集并整理出美国、日本、大陆及国内等相关建筑和消防规范的执行现况，以了解目前国际上在消防管路方面所采取的耐震设计手法，本研究也同时汇整了目前国内重大科技厂房新建工程在消防撒水管路耐震吊架上，所采用的设计案例和实际装置后照片，祈能藉由此案例唤起国内相关主管单位和消防业界对建筑物内消防安全设备耐震力设计的关注，共同研议订定出明确、实用且可供大家遵循的消防安全设备耐震设计准则，以减低国内在地震后火灾所造成的危害。
