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.     

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…     

一般回路形式下的暗条电流平衡高度

Ｋｉｐｐｅｎｈａｈｎ－Ｓｃｈｌｕｔｅｒ模型回路和Ｋｕｐｐｅｒｕｓ－Ｒａａｄｕ模型回路是暗条电流回路的两种极端形式，本文则从一般回路形式来研究暗条电流与暗条高度的关系。结果发现：当暗条电流与活动区磁场作用的Ｌｏｒｅｎｔｚ力方向与暗条重力方向相同时，流入活动区光球层的电流越大，其在暗条电流中所占的比例越大，暗条越稳定。     

Progresses in geology and hazards analysis of Tianchi Volcano

A number of different lahars have been recognized from a systematic survey of a mapping project. The high setting temporamre feature of the deposits indicates a relationship between the lahar and the Millennium eruption event of Tianchi Volcano. The lahars caused a dramatic disaster. Recognize of the huge avalanche scars and deposits around Tianchi Volcano imply another highly destructive hazard. Three types of different texture of the avalanche deposits have been recognized. There was often magma mixing processes during the Millennium eruption of Tianchi Volcano, indicating a mixing and co-eruption regime of the eruption.     

白石坡银多金属矿区火山机构与成矿地质作用初探

区内火山活动早期为火山爆发成岩;晚期演化为岩浆侵入或隐爆两种成岩方式。矿主要受控于潜火山岩带、放射状断裂破碎带中。成矿是在晚期岩浆活动过程中,所携带的含矿介质叠加和热液作用活化了围岩中有用矿质迁移聚集而成,成矿作用与火山作用有着内在联系。     

丽江高美古的二期选址——望远镜地面高度的确定

在丽江高美古前期选址工作的基础上^[1-2]，二期选址的望远镜地面高度的确定工作于2000年11月3日至2000年12月16日进行，采用30m铁塔的温度脉动测量装置，对6#选址观测点的近地面大气湍流进行反复多次测量，得到近地面不同高度(4-30m和8-22m)上每夜温度结构系数CT^2的平均值，对观测取得的资料作进一步处理和分析，得到高美古6#观测点的望远镜地面高度为13～15m。
