Experimental Research on Microscopic Indicators of Temperature＇ s Returning-to-Zero in Deformation of Calcite and Discussions of Correlation Problem

In order to determine the degree of returning-to-zero of temperatures of deformed calcite, a series of rock-breaking experiments were designed to test calcite-rich limestone samples under fixed confining pressures and different temperatures. The consolidated deformed samples in their initial state were observed under a microscope and the microscopic indicators in different zero-returning states were put forward, thus providing a microscopic foundation for evaluation of reliability of dating values of deformation in calcite. At last, the correction of dating values of deformation for samples whose temperature has not yet returned to zero is discussed.     

邹城市峄山省级地质公园揭碑开园

9月15日上午，峄山省级地质公园揭碑开园仪式在邹城市峄山举行。山东省国土资源厅领导及济宁市、邹城市有关领导和部门负责同志出席了揭碑开园仪式，并参观游览了峄山地质公园。峄山省级地质公园位于邹城市市区东南部，总面积约80平方千米。主要包括“七山一水”为主的自然地质景观和人文历史景观。作为主要标志、第一高峰的峄山，海拔582．8米，素有“邹鲁灵秀”、“岱南奇观”之美誉，被誉为“神州怪石第一山”、“天下第一奇山”。区内纵横交错的花岗岩节理，直插天表的花岗岩奇峰，     

1999年8月11日日全食期间的重力吸引效应研究

对1999年8月11日日全食阴影扫过欧洲期间,设在Annelles,Uccle,Walferdange和Bondy弹簧和超导重力仪的记录进行了分析.为了确定月亮对太阳万有引力可能的遮挡效应的极限,对超导和弹簧重力仪记录进行了比较.同时也对LCR和阿斯卡尼亚重力仪观测结果进行了讨论.结论是如果日食重力吸引效应存在,它应在超导重力仪±1 nm/s2(0.1×10-8ms-2)的观测精度范围之内.研究发现在以上情形下,弹簧和超导重力仪都在它们的精度范围内工作,并且日食引起的异常环境干扰可能使重力信号有重大的改变.     

理论学习贵在真学真用

毫无疑问，我们学习马克思列宁主义、学习毛泽东思想、学习邓小平理论和“三个代表”重要思想，其目的只有一个，那就是应用。正如毛泽东同志所指出的那样：“对于马克思主义的理论，要能够精通它、应用它，精通的目的全在于应用。如你能应用马克思列宁主义的观点，说明一个两个实际问题，那就要受到称赞，就算有了几分成绩。被你说明的东西越多，越普遍，越深刻，你的成绩就越大。”     

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.     

MERLIN Images of Five Compact Symmetric Object Candidates at 1.6 GHz

1 INTRODUCTIONCompact Symmetric Objects (CSOs) are powerful and compact sources (overall size <1 bpc) with lobe emission on both sides of the central engine. The small size of these sourcesis almost certainly to be attributed to the youth of the sources themselves (ages < 104 yr) andnot due to a dense coallning medium (Readhead 1996). The unification scenario assumes thatCSOs evolve into compact steep spectrum (CSS) sotirces and then into Fanaroff-Riley type 11objects (Fanti 1995). …
