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…     

由对FRⅡ射电星系的X射线观测试预言射电噪活动星系核的X射线喷流

在早期的文章中,基于耀变体(Blazar)的知识,我们预言了在射电噪活动星系核(AGN)中心10 kpc范围内X射线喷流的存在.钱得拉(Chandra)卫星最近对低功率射电星系的X射线观测与我们的预言相一致.在本文中我们研究了kpc尺度喷流中的电子加速,并建议通过对强的FR Ⅱ射电星系中所预言的X射线喷流的钱得拉卫星的X射线的观测,来研究红的耀变体中的康普顿冷却以及在内部致密喷流和大尺度延伸喷流间环境的不同.以上的研究可以进一步检验我们的关于射电噪活动星系核中kpc尺度X射线喷流的模型.     

海尔—波普彗星的一个可能的巨大等离子体喷流

１９９６年９月１１日，使用上海天台１．５６ｍ望远镜和Ｓｅｒｉｓ２００ＣＣＤ照相机，在Ｂ波段发现海尔－波普彗星有一个巨大的喷流，初步认定为等离子喷流。     

凤太矿田层控铅锌(铜)矿床的成矿物质来源探讨

秦岭凤太矿田层控铅锌(铜)矿床的金属物质、硫和成矿溶液主要来自深部基底的岩石,属海底喷流—沉积成因矿床。从这一理论认识出发可进一步分析控矿地质条件及今后在该区有效地寻找同类矿床。     

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.     

高准直双极分子外流速度的“哈勃”律

在高准许直双极分子外流中，气体速度和离中心恒星距离的“哈勃”关系，可能是分子外流物理性质中最关键的特征。高速喷流驱动弓激波的方式能够解释这种速度结构。本建立起一组喷射角可变的微分方程组。用数值方法得出分子外流的速度结构，这些结构非常类似于观测结果。
