兴1井水位的映震特征

兴1井是辽宁省内最早建成的静水位观测井，已有近20年的观测历史。系统分析预测以来的资料，发现该井水位有很强的映震能力并有一定的映震规律，可进行单井水位异常预报地震震级与发震时间的科学试验。     

灰色系统理论在单桩静载荷试验中的应用

为了通过预测单桩沉降量去估算其极限承载力,基于静载荷试验所得的桩基沉降量具有灰指数律特征,将荷载Q看作广义的时间,建立了荷载序列的等步长及非等步长GM （1,1）预测模型.工程实例证明,所建立的灰色预测模型具有较好的实用性和创新性.     

Study of the erosion rates in the upper Maracujá Basin (Quadrilátero Ferrífero/MG,Brazil) by the in situ produced cosmogenic 10Be method

The present work quantifies the erosive processes in the two main substrates (schists–phyllites and granites–gneisses) of the upper Maracujá Basin in the Quadrilátero Ferrífero/MG, Brazil, a region of semi‐humid tropical climate. Two measuring methods of concentration were used: (i) in situ produced ¹⁰Be in quartz veins (surface erosion rates) and (ii) ¹⁰Be in fluvial sediments (basin erosion rates). The results confirm that (i) erosion tends to be more aggressive close to the headwaters than in the lower parts of the basin and (ii) the region is now affected by dissection.

沁水煤田霍东地区山西组主要煤层对比

运用标志层、层间距、物性特征、煤层本身特征等方法，对霍东地区沁安矿区和沁源矿区山西组1号、2号、3号煤层进行对比，认为沁安矿区未沉积3号煤层，该矿区现有的两个煤与沁源矿区的1号、2号煤层可比，而不是2号、3号煤层，其中既有定性又有定量，较成功的解决了南北两大矿区山本组主要可采煤层间的对比问题。

Modeling of dioctahedral 2:1 phyllosilicates by means of transferable empirical potentials

 Dioctahedral 2:1 phyllosilicates with different interlayer charge have been studied theoretically by using transferable empirical interatomic potentials. The crystal structures of pyrophyllite, muscovite, margarite, beidellite, montmorillonite, and different smectites and illites have been simulated. The interatomic potentials were able to reproduce the experimental structure of phyllosilicates with high, medium and low interlayer charge. The calculated structures are in agreement with experiment for the main structural features of the crystal lattice. The effect of the cation substitution in the octahedral and tetrahedral sheets on the structural features has been also studied. Good linear relationships have been found, and the calculated effects are consistent with experimental results. Some unknown structural features of the crystal structures of clays are predicted in this work. Received: 8 March 2000 / Accepted: 19 September 2000

密1井水位在日本北海道7.8级地震震前的异常反映

黑龙江省密山市密１井水位于１９９３年７月１２日２１时１７分日本北海道西南海域Ｍｓ７．８级强震前４天开始出现的水位异常现象，这可能是地下水位的远场前兆效应，对强震孕育过程的理解提供了新的科学线索。     

对中强地震发震时间的模糊灰色预测

本文视地震系统为模糊灰色系统,由此建立关于发震时间的模糊灰色预测模型,该模型认为已知地震样本集及待预测集的震级分布属模糊正态分布,应用模糊聚类思路于样本集元素的选取,引入最佳震级从属函数μ~*的选择过程。针对可能产生的趋势性偏差,根据实际资料对模型进行了修正。并以华北平原地震带、燕山渤海地震带及山西地震带为例,对模糊灰色GM(1,1)预测模型的实际应用及有关问题进行了初步讨论。
