FEASIBLE STUDY ON THE INTEGRATION SYSTEM FOR THE SPACE MONITORING OF MAJOR EARTHQUAKES AND VOLCANOES IN TERRESTRIAL LAND

With the rapid development of space technology, earth observation technology and sky observatory technolo-gy, they have played a more and more important part in monitoring and predicting of earthquakes and volcanoes in the terres-trial land. In recent years, the related agencies have done the experiments and researches on monitoring and predicting ofearthquakes and volcanoes in the forewarning period by means of many approaches, such as satellite thermal infrared re-mote sensing (TIRS), Global Positioning System (GPS), differential interferometric synthesis aperture radar (D-INSAR),astronomical time-latitude residual anomaly, and Geographic Information Systems (GIS), etc. A quite large number of re-search foundation has been built in the fundamental theories and application methods. The experiments and researcheshave shown that these technology is efficient methods for high frequency crust movement. If the existed separate scientificforces and results are possibly assembled together to form a more complete integration monitoring system with the combina-tion of space, sky observation, ground, deep geology and macro anomaly, it will come into a new stage of monitoring andpredicting of earthquakes and volcanic eruptions.     

梦想晚白垩纪公园

晚白垩纪是地质学的一个新名词,距今大约五千万至七千万年. 轻轻的,我像往常一样走进这片熟悉的土地.如果没有人告诉我,脚下这块偌大的冲击盆地在白垩纪早期竟是一个碧波荡漾的湖泊,很难想象它有多么的古老.     

4种重金属离子及其混合液对壶状臂尾轮虫的急性毒性试验

研究了铜、锌、镉、铅离子及其混合液对壶状臂尾轮虫(Brachionus urceus)的急性毒性影响，实验结果表明，Cu^2 、Zn^2 、Cd^2 、Pb^2 对壶状臂尾轮虫的24h LC50分别为83．18μg/L、4．27mg／L、7．60mg／L、23．44mg／L，将4种离子按照质量比120：20：6：1的比例配成混合金属溶液，其混合液对壶状臂尾轮虫的24h LC50为0．42mg／L。     

Atmospheric radiative transfer simulation for atmospheric correction of remote sensing data

IntroductionThe radiance leaving the earth-atmosphere sys-tem which can be sensed by a satellite borne ra-diometer is the sum of radiation emission fromtheearth surface and each atmospheric level that aretransmittedtothe top of the atmosphere.The radia-tion emissionfromthe earthsurface andthe radianceof each atmospheric level can be separated fromtheradiance at the top the atmospheric level a satellitemeasured.Thus,the earth surface parameters willbe retrieved from the surface radiance after a…     

基于ARP协议的网络主机地址的识别技术研究

从移动IPv6工作原理入手，IP地址管理器是针对越来越严重的IP地址盗用现象而设计的一套有效的监控和管理IP地址的方案。分析与研究IP地址管理器中的信息收集模块后，以Winpcap为开发工具，利用ARP，附等协议完成对网络中活动主机的扫描以及信息（主机名、MAC、操作系统）的收集和识别。模块实现了对网络的自动实时监控，有效地提高了管理效率。     

花岗岩与海底火山熔岩

在郑州开往南阳的汽车上,老师给我们介绍了花岗岩,还搬出了标本让我们认识。老师告诉我们,花岗岩是由长石、石英和云母三种主要矿物组成,是地下滚烫的岩浆上升过程中,在地壳中冷凝形成的。想到一块小小的石头,却蕴藏了这么多的地球故事与秘密,我的心中便对我们的下一站——宝天曼地质公园充满了向往。终于到了宝天曼地质公园,我看到了雄奇险峻的化石尖,那是一座由灰白色的花岗岩组成的巍丽山峰,海拔1830米。虽然山势险峻,我们的队员们却没有一个畏惧的,大家迫不及待地开始攀登起来。尽管同学们一个个都大汗淋漓,汗湿衣衫,可一想到一会儿到了…

柴达木盆地东北缘古元古代变质镁铁—超镁铁质岩的地质特征及成因探讨

1:5万区域地质调查工作中,在柴达木陆块北缘首次发现古元古代变质镁铁—超镁铁质岩,获得成岩年龄为1952±15Ma,其岩石化学、地球化学特征反映出岩浆来源于亏损地幔,反映出该地区克拉通在古元古代(19亿年)发生了一次强烈的裂解(洋)事件,对于研究柴达木盆地北缘元古代结晶基底地质构造演化及进一步探讨柴达木盆地的起源及构造演化过程提供了重要地质线索。
