The mineral rock - silica rock mostly composes of three kinds of silica qualities , and the first structure jasper silica rock , the second icrocrystal quartzite , the third the quartz grain clast . cement is carbonate , contain a little amount carbonate loach . silica rock , commonly assume edge angle or hypo - edge angle 区内的含矿岩石?硅质岩主要由三种硅质成分构成，第一种为显脱玻?霏细结构的碧玉质硅质岩，第二种为微晶石英岩，第三种为石英颗粒内碎屑。
Under the guidance of theories such as the theory of human settlements , the theory of sustainable development , the theory of urban ecology and the theory of ecological economics , the dissertation sets up mathematic model and chooses a suitable index system , which is composed of 4 subsystems and 11 hypo - subsystems and 33 assessment elements , to assess the situation of the urban human settlements of lanzhou in four aspects , including the nature subsystem , the construction subsystem , the supporting subsystem and the society subsystem 为了全面评价兰州的人居环境，论文从组成城市人居环境的自然子系统、建筑子系统、支撑子系统和社会子系统等方面，以人居环境理论、可持续发展理论、城市生态学及生态经济等理论为指导，通过建立数学模型，构建了能够充分反映兰州城市人居环境的评价指标体系，该体系由四大子系统、 11个次子系统和33个具体评价因子组成。
The third section : the effectiveness of eigentumerhypothek in the part , the author separately discusses the force of the die eigentumerhypothek mit forderung and the eigentumerhypothek ohne forderung . the thesis holds that the obligee ca n ' t initiatively exert the hypothec , can deal with the stake according to the law , and as to die eigentijmerhypothek mit forderung , the stake can be picked out from the bankruptcy , but the ei gen turner hypo thek ohne forderung ca n ' t be so . the fourth section : the necessity of accepting eigentumerhypothek in the part , the article argues that adopting eigentumerhypothek meets the need of insuring the benefit balance between the parties , of strengthening our hypothec legislation , and of development of the economy and the judiciary practice 第三部分所有人抵押权的效力在这个部分，笔者从所有人抵押权的处分、抵押物的处分、抵押物在破产法上的别除权以及所有人抵押权的实行等四个方面分别对保有债权的所有人抵押权和不保有债权的所有人抵押权的效力进行了论述，认为所有人抵押权既然不是一种抵押权，当然无抵押权的固有效力，因而权利人不可以主动实行所有人抵押权，而抵押物仍然可以依法处分，保有债权的所有人抵押权，其抵押物在破产法上享有别除权，而不保有债权的所有人抵押权则不享有别除权。
Pe pipe is used for gas engineering so early overseas that urban gas pipeline network in many developed country is made up of pe pipes , which are developing in the trend of hypo - high pressure gas transmission system . these coutries are extending the use of pe100 , the fourth generation of pe product . meanwhile , they have advanced and well - developed technology standard from manufacturing to application 国外在聚乙烯燃气管道应用上起步较早，许多发达国家的城市燃气管网均采用聚乙烯管道，目前正在逐步向次高压燃气输配系统延伸，大面积推广使用pe100级第四代聚乙烯产品，并拥有一套从原料生产到工程施工的先进的完备的技术标准体系。
It result in water level rising , hypo - salinification aggravating , sediment silting up , the lake atrophy , marsh extending and nature disaster such as droughu waterlog ^ salinification occurring frequently . completely analysis to geology and hydrology conditions of the district along yellow river in shandong has been applied in this paper and aquifer ' s hydrological characteristic and subsurface flow ' s characteristic have been analysed as keystone in the paper . after finding out the distribution rule and formation conditions of the shallow layer " s ground water resource , divide the district into three hydrological sections according to hydrological conditions and subsurface flow characteristic 本文对山东沿黄地带地质、水文地质条件进行了全面系统的分析，并重点分析了区内含水层的水文地质特征及地下水运动特征，进一步查明了浅层地下水资源的形成条件和分布规律，根据水文地质条件及地下水运动特征，划分出三个水文地质区，划分并论证了粘土裂隙含水层的形成及供水意义；确定了科学的水文、水文地质参数，为准确地计算浅层地下水资源奠定了可靠的基础；根据浅层地下水资源形成特点，建立了地下水均衡方程式，据此，计算了区内浅层地下水资源及浅层地下水可采资源。
The passed - joint hypo - beam as the first line of defence organization against horizontal force ineluctably bear most curves during the first period under the seismic force , which ca n ' t be balanced by the pre - stressing force of the pre - stressed hypo - beam , therefore , the first crack will occur on it ' s end and at last develop into the plastic - hinge 2 、通过本次试验，并结合他人的一些研究成果，我们应该可以认为边梁扭矩对节点的受力性能是有利的。弯、剪、扭的受力机制并不会使节点的抗震性能有明显的降低。
Based on the project named 《 seiwave earthquake deposit layer forecasting and well deploying system 》 which is presided by daqing oil field limited liability company reconnaissance exploitation academe . it implement graphics display module , graphics manipulation module , graphics filling module and optimizing of plot speed in 《 three - dimensional earthquake interpret hypo - system 》 which is the core portion of 《 seiwave earthquake deposit layer forecasting and well deploying system 》 . it is deeply investigated the special knowledge of earthquake interpret 本文以《 seiwave地震资料储层预测与井位部署系统》项目为依托,深入研究了此系统中相关的图形显示知识和专业知识,实现了《 seiwave地震储层预测与井位部署系统-三维地震资料解释子系统》中图形显示、图形操作、图形填充功能和绘图性能的优化,进一步提高了油田的勘探效率。
Three representative mega steel - frame structures are selected . four calculative modes are hypothesized , which are , mode 1 : considering the main - frame , not considering the floor stiffness ; mode 2 : considering the cooperation of main and hypo frames , not considering the floor stiffness ; mode 3 : considering the cooperation of main and hypo frames , and the floor stiffness ; mode 4 : considering the main - frame and the floor stiffness 本文选取了具有代表性的3个巨型钢框架结构作为算例，假设了4个计算方案，即方案1 ：仅考虑主框架、不考虑楼板刚度；方案2 ：考虑主、次框架协同工作、不考虑楼板刚度；方案3 ：考虑主、次框架协同工作和楼板刚度；方案4 ：仅考虑主框架和楼板刚度。
Based on the classification of images , this paper gives out four digital image steganography techniques which have good conceal effect , including low - three - bits hiding strategy , odd - even of hypo - low bit hiding strategy , deviation of adjacent - field hiding strategy and self - adaptive deviation of adjacent - field hiding strategy . on digital watermarking aspect , this paper gives two blind watermarking strategies which have good conceal effect and high robustness , they are single - watermarking strategy based on minimal - value exchanging and multi - watermarking strategy which hides the same watermark copy on the different parts of an image 在对图像进行了分类的基础上，本文给出了四个具有较好掩密效果的数字图像隐写策略，包括低三位隐藏策略、次低位奇偶策略、邻域方差策略和自适应邻域方差策略；在数字水印方面，提出两个掩密效果好且鲁棒性较高的数字图像盲水印策略，分别为基于最小值交换法的单一水印策略和嵌入同一水印多个副本的多水印策略。
