Through analysis of the drilling load characteristics , considering the drilling speciality, basic power driving requirement of the geological drill and automotive emission requirement, this paper discuss how to select power in design of mobile drill rig, engine selection of DPP100 series.

通过对钻探负载特性的理论分析，结合钻探工作的特点和环保对汽车排放的要求，按照地质钻机对动力系统驱动特性的基本要求，对DPP100系列钻机车动力系统选择的研究和方法进行了论述。

Dolomite reservoir fracture system, which was structural fracture,was studied by these two methods in Anpeng area of Biyang Depression.The results show that the principal curvature method has obvious deviation when used for a gentle structure latitude district.

研究结果表明，在凹陷内部构造变形幅度相对平缓的地区，采用主曲率法预测构造裂缝时存在较大偏差，而高斯曲率法的应用结果与地质解释、钻井和测井资料吻合较好。

The estimation of signal parameters is an important research field of modern signal processing. It finds wide applications in many fields, such as radar, communications, sonar, seismology, radio astronomy, biomedicine engineering, etc. So, its study is of great theoretical and practical value.

信号参数估计是现代信号处理领域内一个重要分支，它在雷达、通信、声纳、地质勘探、射电天文以及生物医学工程等众多领域有着广泛而重要的应用前景，因此对各种参数估计方法的研究有着重要的理论和应用价值。

It was revealed that the radiolarians in the pebbles dated from Tournaisian to early Visean in age.Geochemical characteristics of the pebbles implied that the radiolarian was deposited in a small oceanic basin,indicating that Kelamaili oceanic basin was closed in the late Early Carboniferous and a quick uprising occurred in the Kelamaili orogenic belt during early Jurassic.

关于两板块缝合的时代，地质学者存在较大争论，有早古生代、泥盆纪、早石炭世不同观点：蔡文俊(1986)根据放射虫研究认为缝合时代为早石炭世[1]，何国琦等(2001)认为克拉麦里造山带是由克拉麦里早古生代洋闭合形成[2]，舒良树和王玉净(2003)根据放射虫动物群对比认为克拉麦里蛇绿岩形成年龄为晚泥盆世法门期—早石炭世杜内

In the past decade, research was mainly focused on the analysis of the combination of rainfall and geological environment.

过去10多年来在这方面的研究主要集中在区域降雨与地质环境的结合方面。

The model of the thesis s forecasting method is synthetical use of experience model method and mine-reserach information adding power model method of mineral resources assessment based on GIS. It use several kinds of analysis means for multi-sources data. Firstly the gold-research prospective domains of this area are forecasted through the spatial query and ana-lysis by means of GIS,based on geological and mineral information of thearea, synthesizing geochemistry anomaly information. Gridding inserting value transforms geochemistry data of sampling point of the south of Acixiarega from scattering data to grid data by means of the development of Delphi and Mapobjects, using distance reciprocal inserting value method. After deposit orientation analyse and spatial overlapping analysis by means of CIS, the gold-research prospective domains of the area are forecasted.

本文所建立的预测方法模型是基于GIS矿产资源评价方法的经验模型法及找矿信息加权模型法的综合使用，对多源数据采用多种分析手段，先以研究区1：5万区域地质资料和矿产资料为基础，综合地球化学异常资料，通过Mapgis的空间检索与分析，做出全区成矿有利区分布图；而阿次夏热嘎南部地区离散的采样点的地球化学数据，是采用面向对象编程语言Dephi与GIS控件Mapobjects为开发工具，运用距离倒数插值法进行插值网格化，从而将离散的数据转换为栅格型数据，矿床定位分析、GIS空间迭加分析，预测出该地区成矿有利区。
