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。

The individual density was 4.77 inds. per gram dry soil. The results indicated that the number of soil nematode fluctuated significantly with season, the number of soil nematode in autumn is significantly more than that in summer and in spring. Shannon-Wiener index, Pielou index, Margalef index and Trophic diversity index were used in analyzing the diversity of nematode community, ranking Cc＞Pm＞Clc, while Simpson index ranking Pm＞Clc＞Cc. The value of f/b, MI index, PPI index, MMI index, MI2-5 index, SI index and EI index were used in analyzing the characteristics of the functional structure of the nematode communities, ranking Cc＞Pm＞Clc, while PPI/MI value ranking Clc＞Pm＞Cc. It showed that the Clc was disturbed significantly.

研究结果表明，土壤线虫数量存在明显的季节波动，秋季明显高于夏季和春季；土壤线虫群落多样性指数、均匀度指数、丰富度指数和营养类群指数大小依次为阔叶林、针叶林和混交林，而优势度指数却表现为：针叶林＞混交林＞阔叶林；土壤线虫群落营养类群f/b值、MI 指数、PPI 指数、MMI指数、MI2-5指数、SI指数和EI指数均表现为：阔叶林＞针叶林＞混交林，而PPI/MI指数则表现为：混交林＞针叶林＞阔叶林，表明混交林受干扰明显；土壤理化特征与线虫数量、属数、生态指数间也存在明显相关关系。

This paper described the principle of plane ultrasonic spreading abroad in the liquid coming into being ultrasonic grating,educed the density and refractive index changing rule basis continuity equation of not-ideal liquid and Lorentz-Lorenz law,expressing the transformation of the index and refractive index satisfaction similar equation of standing wave,and described the relation curve of the standing wave form at a few special times,liquid density and refractive index periodic variety according to the res...

描述了平面超声波在液体里传播形成超声光栅的原理；根据非理想流体对应的连续性方程和Lorentz-Lorenz定律，推导了液体光栅中液体密度与折射率的周期性变化规律，表明液体密度和折射率变化满足相似的驻波方程；根据推导的结果描绘了几个特殊时刻的驻波波形、液体密度、折射率周期性变化之间的关系曲线；进而由折射率周期性变化规律分析了超声驻波自身像的形成原理，并给出了CGS型超声光栅声速仪利用超声驻波自身像测量声速的方法与实验结果。

refractive index：折射率

核心與[[折射率]](refractive index)較高的纖殼通常用高品質的矽石玻璃(silica glass)製成,但是現在也有使用塑膠作為材質的光纖. 又因為光纖的外層有經過[[紫外線]]固化後的[[壓克力]](acrylate)被覆,可以如銅纜一樣埋藏於地下,

refractive index：折射指数

为了确定这些玻璃碎片来自于被抢劫者打碎的窗户,控方传唤了一个专家证人证明了两点:(1)鞋子里面的玻璃与破碎窗户的折射指数(refractive index)是一样的;(2)在全国使用的玻璃只有4%拥有这种特定的折射指数.

refractive index：折射系数

本发明涉及一种阻挡氢离子渗透的金属层间介电层的制造方法,该方法形成一折射系数(refractive index)为1.6-1.64的第一富硅氧化层于一填充氧化层上,然后再形成一折射系数为1.49-1.55的第二富硅氧化层于该第一富硅氧化层上.

refractive index：折光率

最令他们感奇怪的是;发现必须用几个折光率(Refractive index)不同的透镜组合起来才能克服某些光学偏差(Optical aberrations). 眼睛的晶体利用同样的原理,只是结构上更为精致. 眼睛晶状体,并不是由好几大块折光率不同的单元组成,
