During the oil field exploitation , the key of studying reservoir heterogeneity is high accuracy stratum ' s partition and contrast . fine degree of petroleum deposit ' s partition and contrast direct decide cognition ' s deepness and precision of that reservoir 在油田开发过程中，高精度地层的划分和对比是进行储层非均质性研究的关键性工作，油藏层组划分和对比的精细程度直接决定了对本区储层认识的深度和精度。
This paper deeply discussed the mechanism of magnetic tape detector , mainly focused on the tape detector appliance in engineering fields , making it not only measure the lightning current peak but also its supreme deepness . my paper is mainly made up of the following parts 本论文对雷电参数测量磁带法的机理进行了较为深入的探讨，着重于开拓磁带测量雷电参数应用领域方面的研究，使磁带既能测量雷电流峰值又能测量雷电流最大陡度。
Now , at home except t he compiling methods of controlling , constructing detailed planning make concrete requirements about the contents and deepness of the road , pipeline systems and other urban planning , there is no complete detailed planning compiling regulation of urban engineering 目前，国内除在控制性、修建性详细规划的编制办法中对道路、管线工程等市政工程规划内容深度作了具体要求外，尚无完整的成文的市政工程详细规划编制规定。
4 . because of input - output is inefficiency , which is limited by the low concentration ratio and expenditure situation , enterprise ' s technological innovation motivation is not enough . this leads to research and development expenditures is poor , the width and deepness of products development is not enough 受制于市场集中度不高和现有的消费状况，投入产出效率低，乳品企业技术创新的激励不足，造成企业研发经费投入和产品开发的深度、广度不足。
The astrocalendar 1999 , published by the provisional urban council hong kong space museum features the deepness of the universe and the most recent splendid photos taken by the hubble telescope . in addition , a new monthly star - map is provided to introduce to you the night sky , the planet and the moon phase visible in each month 月历内选辑了多幅由哈勃望远镜所拍摄的最新精彩图片，更附有全新设计的每月星图，介绍当月星空和可以见到的行星及月相位置。
Chapter 3 and 4 researches soil depurating function and rule to rainwater by soil columniation penetrating examination on the basis of the two former chapters . and it analyses the influence of soil structure , contamination burthen and penetrating deepness to depurating effect , and discusses contaminate cumulation and renewing ability of soil 第三章和第四章在前两章的基础上，通过土壤柱渗透试验，研究了雨水在土壤中的净化作用及其规律，分析了土壤结构、污染物负荷、渗透深度对土壤净化效果的影响，并对污染物的累积和土壤净化能力的恢复进行了探讨。
We first study several teaching theories on modern physics experiments , and next we present the requests of the new era to science teaching and physics teaching . in the last , we probe into some practical issues , such as " windows " and " connection " , " deepness " and " width " , " experiments teaching " and " scientific research " etc , and give some new opinions on these topics 首先提出了近代物理实验教学设计的几种理论依托，探寻了理论与教学实践的结合点；然后分析了新时期对物理或其它科技教育的要求；最后，对近代物理实验教学的“窗口”与“接口” 、 “深度”与“广度” 、 “实验教学”与“科研预演”等若干实际问题提出了自己的见解。
This paper ' s study is focused on the principle of bistatic sar on the basis of giving a brief introduction of sar principle , including azimuth resolution , mapping width , focusing deepness , pulse repetition frequency limitation and radar equation etc . then the paper studies the special form of bistatic sar with stationary transmitter 在简要介绍了合成孔径雷达的成像原理后，本文着重从原理方面对双站sar进行了分析，讨论双站sar的方位向分辨率，测绘带宽，聚焦深度，脉冲重复频率限制，雷达方程等问题，然后对发射机固定的双站sar这种特殊的双站sar模式进行分析。
For some wetland plants such as reed and cattail , a small quantity of petroleum pollutants did not form deadly menace , their growing tallness was positive correlated with water deepness . therefore , wetland buffer can be constructed to reduce the impact of petroleum pollution and plant adaptive wetland vegetation so as to improve the environment of oil field 结果显示：湿地环境对土壤中的石油污染有明显的降解作用，芦苇等挺水植物的生长量与积水深度呈正相关，土壤中少量含油并不构成对湿地植物生长的威胁。
This thesis totally is divided into five chapter . as for chapter 1 , oral communication teaching has been combed from the lengthways angle , which makes us know that our country ' s oral communication teaching has ever walked through the road of a difficult turns and the knowledge of oral communication teaching has been changed from ignorance to stress , from superficiality to deepness ; the chapter 2 from the horizontal angle the courses criteria of li in abord for oral communication teaching are talked of ( e . g the united states , germany , the united kongdom ) , in comparison with syllabus of chinese ; the third , four chapter are the key to thesises . the chapter 3 puts forward and analyzes the present questions of current oral communication teaching ( e . g oral communication teaching ' s value orientation , oral communication teaching ' s materials , oral communication teaching ' s method , oral communication teaching ' s evaluation ) ; the chapter 4 brings up some related counter measures by aiming at this present conditions 本论文共分五章。第一章从纵向的角度对我国的口语交际教学进行了历时的梳理，从中可看出我国的口语交际教学走过一条艰难曲折之路，对口语交际的认识也由漠视逐步到重视，对其概念的内涵的认识也逐步由肤浅到深刻；第二章从横向的角度对国外(以美德英国为例)的口语交际教学(仅从母语课程标准)上来观照，并将其与中国现阶段的课程标准进行比较分析；第三、四章为本论文的关键部分，第三章对我国当前口语交际教学的现状迷失(口语交际教学的价值取向、口语交际教材、口语交际教学方法、口语交际教学评价等四个维度)进行了较深层次的剖析与“诊断” ；第四章针对这些迷失的现状本文提出了一些相关的对策研究。
