FORMATION OF LARGE-SCALE TECTONIC ELEMENTS FROM THE POSITION OF CENTRIFUGAL-INERTIAL FORCE ACTION

We describe the earlier unknown, when applied to global tectonics, centrifugal inertial mechanism of lithosphere plate moving under the effect of forces appearing as a result of Earth‘s planetary rotation. The mechanism stated gives an insight into global tectonics of plates with the indirect participation of emanation streams which, in their turn, are the derivatives of centrifugal and inertial forces of planetary motion. The application of this mechanism provides a logical explanation for the regularities of global tectogenesis including the formation of mountain ridges mainly of submeridional and sublatitudinal strike, and also the drift of continental plates from the east to the west and from the south to the north. The mechanism clarifies the significance of the Arctic and the Antarctic Circles as geodynamic barriers.     

地形对地表二向性反射测量的影响(英文)

该文重点研究不同空间分辨率下粗糙地表的表面二向性反射测量。这里将不同二向阴影函数和计算机模拟技术进行了对比，所用到的计算机模拟技术包含射线追踪和基于人造表面和３０ｍＤＥＭ数据的辐射通量法等。所有算法都显示出地形对辐射度量有显著影响，然而，它们同时揭示了诸多模型之间存在着很大的差异，如果想准确估计地形对二向性反射分布函数的影响，就必须做进一步的研究。     

热带高反射云及典型特征分析

利用1971—1983年全球热带高反射云(HRC)资料,研究热带不同地区HRC的位置、频率等特征的月、季变化。例如,大西洋上HRC全年呈带状分布随季节有弱的南北向位移,而太平洋的中西部呈双HRC型结构。还分析了厄尔尼诺期间HRC的异常情况。     

日本三池煤田煤中的假镜质体及其对结焦性影响

本文对日本三池煤田有明矿本层煤和上层煤的系统分层样品进行了媒岩鉴定和工业分析。总结了煤层剖面中煤岩煤质特征的垂向变化。尤其,在本层煤和上层煤中普遍发现假镜质体,这种假镜质体是原生氧化形成的。它对煤的结焦性产生较大的影响。     

弹性波反射法在桩基检测中的理论与应用

根据波动理论探讨了弹性波在砼桩中的传播衰减规律及反射特征，提出了判断桩基质量的有关理论依据，并结合工程实例应用弹性波反射法讨论了时域、频域分析法的基本原理及存在问题．     

薄互层反射特征及解释方法在樊家地区的应用

对悬索桥结构分析的有限位移理论作了线性、非线笥及大位移理论的区分。分析表明，线性化有限位移理论能为成桥后的分析提供准确而又偏安全的结果，而对架设过程的分析，则必须采用大位移理论进行计算。     

不透明矿物的反射光谱鉴定

Reflection spectrum of mineral is a curve of the reflectance of the mineral against the wave-lengths of reflected light. It reflects the variation of reflectanee with changing wave-length and provides some useful information on other optical properties of the mineral under linear polarized light such as eolour, bineflection, reflection pleochroism, etc.Each mineral is characterized by its unique reflection spectrum. A set of nine reflection speetrum diagrams are compiled by the author for more than 200 common minerals.Reflection spectrum is markedly lines of different patterns for minerals with isotropism,bireflestion, reflection plcoehroism and the overlapping of Rg and Rp. Only one spectrum is given for each mineral and only Rg spectrum is presented for anisotropic minerals. These diagrams afford a practical means of opaque mineral determination on the basis of reflective property of minerals.
