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.

对青藏东北缘现今块体划分、运动及变形的初步研究

利用2维非连续变形分析方法（DDA），以位移代替围压作为边界约束力，研究青藏东北缘现今块体划分及其运动变形。根据该地区地质构造及地震活动，以GPS点测量位移作为模拟结果约束点，得出了较合理的块体划分模型和随时间演化的主应变分布图，并把应变高值区与近几年来发生的5级以上地震作对比，得出了研究区内地震危险性可能较大的区域。另外，对模拟的甘青块体与阿拉善块体的边缘带断裂左旋运动做了大概计算。     

Influence of the Choice of Core-Envelope Transition Point on the Binary Merger of Two Main-sequence Components

We have studied the influence of different choices of core-envelope transition point on the final merger of contact binaries with two main-sequence components. A binary of 1.00 + 0.90M⊙ with an initial orbital period of 0.35d is examined. The mass fraction of the primary mixed with the matter of the secondary, qmix, determined by the chosen core-envelope transition point, ranges from 0.04 to 1.00 in our analysis. If as qmix< 0.8, none of the     

四个PG类星体的谱能结构与红外辐射机制

本文利用宽波段能谱结构讨论了四个PG类星体的红外辐射机制．结果表明，在产生红外连续辐射的可能机制中，非热的、具有幂律特征的辐射和被核光度加热的“核尘埃”的热再辐射是红外辐射的主要来源．对于高光度的活动星系核，它的主星系的红外辐射及恒星形成区的红外辐射是可以忽略的．     

三级监察网络——煤矿违法开采的“克星”

面对超层越界、无证采矿和以采代探等违法采矿行为屡禁不止这一“顽疾”，禹州市国土资源局主动探索，推陈出新，走出了一条行之有效的执法监察新路子，即实行局各资源所(站)、测绘大队和执法大队三级监察网络，避免了违法行为排查的被动性、巡查的盲目性、查处的滞后性，做到了有计划、有重点、早发现、早制止、早处理，将一大批矿业违法活动消灭在萌芽状态，煤矿违法开采活动数量明显减少。
