The chemical-petrographic types of these meteorites are presented below.Six are unequilibrated ordinary chondrites,including three H3 and three L3;92 meteorites are equilibrated ordinary chondrites,including 24 H-group(13 H4,10 H5,1 H6),64 L-group(2 L4,44 L5,18 L6) and 4 LL-group(3 LL4,1 LL5);the other two belong to stone-iron meteorites.In 6 unequilibrated ordinary chondrites,chondrules are well-shaped,and olivine and low-Ca pyroxene are commonly zoned and have wide ranges of composition.The olivine and low-Ca pyroxene in the other 92 equilibrated ordinary chondrites have similar composition,respectively,and to some degree it reflected thermodynamics equilibration in olivine and lowCa pyroxene.

并根据矿物-岩石学特征，划分了它们的化学-岩石类型：6块属于非平衡型普通球粒陨石(H3和L3群各3块)；92块属于平衡型普通球粒陨石，包括：H群24块(13块H4，10块H5，1块H6)，L群64块(2块L4，44块L5，18块L6)，LL群4块(3块LL4，1块LL5)；另外两块属于石-铁陨石。6块非平衡型普通球粒陨石保存了原始的岩石学和矿物化学特征，包括：清晰的球粒结构、橄榄石和低钙辉石具有明显的成分环带以及极不均一的化学组成等。92块平衡型普通球粒陨石中的橄榄石和低钙辉石显示出均一的化学组成，表明它们达到了一定的热力学平衡。

Geophysical characteristics of Ordovician carbonate rock were studied using drilling data. Impedance is affected mostly by material properties and reservoirs types, to a negligibly extent by lithology and flow. Compact layers and minor\|fracture reservoirs of Ordovician carbonate rock have characteristics of high density, high velocity and high impedance, and the prediction of minor fractures reservoir is difficult by the general seismic ways. Big fractures and fractured\|vuggy and vuggy and cavity reservoirs of Ordovician carbonate rock have characteristics of minor density and low velocity and low impedance in central Tarim basin, which obviously different from the surrounding rock and produce obvious characteristics in seismic data, so reservoirs can be predicted by applying general seismic data.

根据已钻井资料，对塔中地区上奥陶统良里塔格组岩石地球物理特征进行了研究，结果表明：物性、储层类型对波阻抗影响最大，岩性、流体对波阻抗影响较小；奥陶系碳酸盐岩致密层和小裂缝型储层具有密度大、速度高、波阻抗值大的特点，利用地震常规预测手段较难预测出小裂缝型储层，而塔中地区奥陶系碳酸盐岩大裂缝型、裂缝-孔洞型、孔洞型、洞穴型储层具有密度小、速度低、波阻抗值小的特点，与围岩具有较为明显的差异，在地震上可以产生明显的响应，可利用常规地震资料来预测这种类型储层。

Under the effect of nature condition and social-economic growth condition of Hebei province, the urban system around Bohai Sea in Hebei province showing the characteristic as follows: Firstly, it is divided into two parts of north and south by Beijing and Tianjin. Secondly, the economic strength of the coastal areas is not strong although it near to Bohai Sea. Thirdly, the urban system is obviously draw by two cores and broken up by hinderland. Fourthly, there are great differences between spatial distributions of the cities; they distribute a disproportion in the whole.

1河北省环渤海城市体系是河北省城市体系的一部分，受河北省自然及社会经济条件发展的影响，河北省环渤海城市体系呈现以下特征：第一，被京津南北分割；第二，外环渤海，但沿海经济实力不强；第三，两核心牵引和腹地分割的空间格局明显；第四，城市空间分异明显，整体布局不均衡。

One hand, as the same as others project management, the highway engineering project management is a complicate, arduous system engineering. It includes tempo, quantity, investment, contract, personnel, risk, drawing list, archives and so on. But in the other hand, it has open-and-shut character to itself-geoscience character.At the present time, there are some kinds of project management software.

同其它类型的项目管理一样，公路工程项目的管理是一个复杂、艰巨的系统工程，涉及进度、质量、投资、合同、人员、风险、图纸、文档等多方面的工作；但另一方面，公路工程项目的管理又具有明显有别于其它工程项目管理的特征：地学特征。

The proposed algorithm first detects smooth intervals based on gray variance from the original frame sequence, then concatenates them to constructs a new frame sequence. After that, video features such as pixel-wise difference, HSV histogram difference and edge histogram difference are fed to a SVM classifier to decide the types of different shot boundaries.

第一级分类器根据视频帧灰度方差特征，将无明显变化的视频序列从原始视频序列中分离出去，得到一个新的视频序列；第二级分类器在新视频序列的基础上，提取视频图像的像素对差值、HSV空间颜色直方图的各分量差值以及边缘直方图X，Y分量差值等视频特征，并采用支持向量机多分类策略进行镜头边界类型的检测。

From the analysis of the magnetic susceptibility,TOC,TN,pigment,organic car-bon isotope ,HI,saturated hydrocarbon and 14C dating etc. of the sediment samples from coresof two boreholes in the Taihu lake,a knowledge of the evolution of paleoenvironment of thelake during the last 14ka is achieved. The results show that the lake has undergone the fol-lowing stages .. The Lake was at a low level ,or even became exposed during 14.3-13.3kaBP,reflecting an arid climate. There existed a transitional stage during 13.3-12.4kaBP,the climate being slightly warm and wet. There are indications of a cold and dry climate around 11.5kaBP,probably corresponding to the Younger Drays event ,comparable with other areas in east China.

本文根据东西太湖短柱岩芯的沉积物的物理、化学、生物指标的综合分析，讨论了该区距今14ka来的古气候变化过程，结果表明14.3-13.3kaBP，太湖水位低，环境指标甚至表现为暴露特征，反映了气候干旱：13.3-12.4kaBP，为偏暖湿的过渡阶段；该孔柱270-280cm(11.5kaBP左右)各类指标均明显更映冷干特征，可能是Younger Drays事件的记录，与我国东部其它地区有可比性；约10.9-10kaBP，这一时期是整个研究时段内一个较显著的温暖期。

A number of geological and mineral composition and geochemical investigations indicate that the deep geodynamics process and mantle characteristics of middle Jurassic gabbros suits from south Jiangxi province are distinguish from Cretaceous gabbros suits from coastal belt of Fijian province, the former are related to mantle upwelling and lithosphere extension, the later are related to subduction and lie on back-arc basin in tectonic environment.

对赣南车步辉长岩类的地质特征、矿物学和地球化学特征进行了研究，着重讨论它与沿海辉长岩类构造环境和源区性质的不同，研究表明它可能是中国东南部中侏罗世软流圈上涌、岩石圈伸展和地壳裂解的产物，而沿海白垩纪辉长岩类的构造环境是弧后拉张盆地；车步辉长岩类的源区可能是未受到明显俯冲组分影响的富集地幔，而沿海白垩纪辉长岩类的源区可能包含较多俯冲组分。
