Used false ceiling material varieties, specifications, colours and grassroots construction, shall be fixed design methodology, and the current standard; Drop keel no distortion, distortion, false wooden keel or the need for fire wood processing vessel analysis, the installation of a reliable keel, around flattened; light lamps can be directly working in reinforced keel, the weight of more than 2 kilograms of lamps or ceiling fan can not borrow drop keel, a separate hanger with LBAC structure liaison metal materials, synthetic materials, PVC ceiling must be installed on the Xidingdeng Long skeleton, the structure must do waterproofing wood fire.

吊顶 吊顶所用材料的品种、规格、颜色以及基层构造、固定方法应按设计要求，并符合现行标准；吊顶龙骨不得扭曲、变形，木龙骨或木质吊顶必须进行防火处理，吊杆顺直，龙骨安装牢固可靠，四周平直；轻型灯具可直接吊在加固龙骨上，重量大于2公斤的灯具或吊扇不得借用吊顶龙骨，应另设吊钩与土建结构联络，金属材料、合成材料、PVC吊顶上的吸顶灯安装必须有龙骨架，木结构必须做防水防火处理。

Based on the example of shahe reservoir, the text makes an analysis on circulation, management and environment and social economy development condition of the surrounding ecosystem. Then, the author carries on inquisition, data analysis and summary and makes calculation and demonstration of the safe stability of the dam ,and discusses the risking obviation and reinforcing technique. Finally, based on the existing research of sustainable development, experts" opinions and Mathematical Statistics analysis, the author brought forward an indication system suitable for reservoirs" sustainable development This system is made up of 4 first class indexes, 13 second class indexes, 38 foundational indexes. The 4 first class indexes are the dam safety evaluating index, the management index of reservoirs, the water ecosystem system stability index, the reservoirs construction effect index. The 13 second class indexes are the construction quality evaluating index, the dam running and management evaluating index, the flood control standard recheck index, the structure safety evaluating index, the anti- earthquake evaluating index, seepage safety evaluation index sign, the metal structure safety evaluating index, the engineering facility index, the management index, the water ecosystem system stability index, engineering effect index, the economic development index, the society development index.

本文以沙河水库为例，对其运行、管理及周围生态环境和社会经济发展状况进行调查，并将调查资料进行分析、归纳、总结；然后对水库大坝的安全稳定情况作出了简要的计算和论证，并讨论了水库的主要除险加固技术；最后在总结现有可持续发展研究的基础上，征集专家的意见，进行数理统计分析，提出了由4个一级指标、13个二级指标、38个基层指标组成的一套适合该水库可持续发展的指标体系。4个一级指标分别为：水库大坝运行安全综合评价指标、水库管理指标、水资源生态系统稳定性指标、水库建设效应指标；13个二级指标分别为：工程质量评价指标、大坝运行管理评价指标、防洪标准复核指标、结构安全评价指标、抗震安全评价指标、渗流安全评价指标、金属结构安全评价指标、工程设施指标、管理指标、水资源生态系统稳定性指标、工程效应指标、经济发展指标、社会发展指标。

This brought fixed cost, but it also is meant at the same time use a source to won't make you singlehanded assume a problem.

这带来了一定的成本，但它同时也意味着使用开源不会让你独力承担问题。
