In order to solve the important and basic problem of the petrogenesis of "Tiantangzhai migmatitic granite" in the core of Dabie orogenic belt, the detailed 1∶50000 regional geological surveying and the big scale dissection of important region (metamorphic rocks, granites and structure), were operated in about 900km〓 area near Tiantangzhai peak. On the bases of the petrology, mineral chemistry, geochemistry of rare earth element and microelement, isotope geochemistry and chronology, physicochemistry, magmatic dynamics, geodynamics, diagenetic simulation, and regional geophysical data, the theory of cooling age and historical geochemistry and the viewpoint of tectonic evolution are applied to study the petrogenesis of Yanshan epoch granites of this region. On the bases of above studies, the process of tectonomagmatic dynamics after indo-Chinese epoch in Dabie orogenic belt is discussed. The important conclusions are gotten

本文针对大别造山带核部&天堂寨混合花岗岩&成因这一重大基础地质问题，在天堂寨一带近900km〓的面积上进行了详细的1∶5万区域地质调查和大比例尺重点区解剖，通过对区内燕山期花岗岩进行岩石学、矿物化学、稀土微量元素地球化学、同位素地球化学和年代学、物理化学、岩浆动力学、地球动力学和成岩计算机模拟等研究的基础上，结合区域地球物理学资料，应用冷却年龄、历史地球化学理论和构造演化观，阐明区内燕山期花岗岩成因，并以此为基础进一步讨论了大别造山带自印支期以来的构造—岩浆动力学过程，取得了如下的重要认识

And when picene (C22H14) is doped with potassium, it superconducts at a relatively toasty 18 kelvins ( 255 degrees C).

This paper studies the correlation between the maximum height s of the Plinian volcanic eruption columns and mass flux of the volcanic eruptions according to measurement data acquired from active volcanoes around the world.

Plinian式火山喷发柱最大高度是研究火山喷发对环境、气候影响时空范围的重要物理学参数，在分析了影响Plinian式火山喷发柱最大高度诸因素的基础上认为，火山喷发的质量通量是反映火山喷发柱最大高度最有效并且在实际中可以进行测量的参数之一，以此为基础，利用目前实测的火山喷发柱最大高度的数值与火山喷发质量通量的结果，建立两者的相关方程为：H＝0。

Freeman Dyson, a venerable and polymathic physicist who has been thinking about the problem, is also a believer in biological innovation.

学识渊博、备受尊敬的物理学剑弗里曼-戴森也一直在思索这个问题，而他也是生物学创新的拥护者。

The development of this is the supreme goal of positivistic philosophy.
