垂向电导度的测量及在水位异常判别中的作用

为剖析咸水进水位异常，我们对位于唐山地震区附近的双桥１号井，双桥２号井及东台子井进行了多次井内垂向电导度的测量。在１９９１年１０月５日宁河ＭＬ４．６级地震及１９９２年７月２２日宁河ＭＬ４．９级地震前井下水电导度特别是含水层部位水电导度都曾出现过高值异常，这对于判别不异常是由于咸水层压力变化还是外来水的侵入是一种行之有效的简便的监测方法。     

华南沿海主要活动断裂带的比较构造研究

华南沿海地区，发育３组不同方向的断裂构造。以北东～北北东向的断裂规模最大，地表迹象最明显；以北东东～东西向断裂切割最深，发育历史最长；而以北西～北西西向断裂的新生性和近期活动性最显著。研究结果表明，上述３组断裂构造的特征，在宏观表征和显微构造特点方面都有表现，说明各组断裂都有各自类同的形成、发育过程，并受控于类似的构造力源，它们的特征在一定程度上反映了地壳运动的演变史

Sq外源和内源电流体系的经度效应和UT变化

根据ＩＧＹ／ＩＧＣ期间全球地磁台网以及中国地磁台站的资料，计算出每－ＵＴ小时的Ｓ_ｑ外源和内源电流体系．对Ｓ_ｑ电流体系ＵＴ变化和经度效应的分析研究表明，Ｓ_ｑ外源电流体系的空间图案没有显著的ＵＴ变化，电流涡焦点的地理纬度与磁赤道有密切关系，其变化范围，北半球为２５°－３５°Ｎ，南半球为３０°－４２．５°Ｓ．外源电流总强度的平均值为２２９ｋＡ（北半球）和１７３ｋＡ（南半球），其变化范围为±５０ｋＡ（北半球）和±４０ｋＡ（南半球）．Ｓ_ｑ内源电流体系的图案和强度有显著的ＵＴ变化，电流体系焦点纬度有类似于外源电流系的变化．在大西洋、印度洋、北太平洋地区，内源电流体系的总强度明显小于大陆地区的内源电流强度，表明这些大洋地区上地幔电导率低于大陆地区．

Pressure Solution of Sulphides in Some Massive Sulphide Zinc—lead Deposits of Western Canada：Its Significance in Mobilization of Ore—forming Materials

Pressure solution is a common phenomenon in massive sulphide zinc-lead deposits of western Canada and may have been an important factor leading to the mobilization of ore-forming materials during diagenesis, deformation and metamorphism of sedimentary ores.The control of ductile shear zones over gold mineralization could be explained in view of pressure solution of gold-bearing miner-als under shearing stress and the tesultant mobilization of this metal.     

Geomorphology and sedimentary/biosedimentary structures of the intertidal environment along the coast of Kuwait,north-western Arabian Gulf

The coast of Kuwait can be divided into nine intertidal geomorphological subunits, of which four are found along the northern muddy shoreline and five along the southern sandy shoreline. In the north the coast is characterized by wide intertidal mudflats, bounded landward by an extensive coastal sabkha which is partly covered by sand drifts. The upper part of the intertidal environment is covered with a mixture of aeolian sands and muddy sediments of marine origin. A number of shallow tidal channels dissect the intertidal flats and small sand bars occur near the low water line. In contrast, the southern shore is characterized by relatively steep sandy beaches fronted by narrow to moderately wide rocky intertidal platforms which are partly covered by sand, bioherms, skeletal debris and algal mats. In some areas the rocky surface is dissected by numerous small gulleys and shallow channels. Multiple sand bars lying either parallel or diagonal to the shoreline are developed near the low water line. This southern intertidal environment is bounded landward by a sandy berm and a wave-cut cliff.Ripple marks are developed almost parallel to the shoreline, showing different flow directions. Energy levels are moderate to high along the southern shore, but low along the northern shore. In the south, waves induced by winds blowing mostly from the north-east and south-east form the dominant energy source, whereas tidal and wind-driven currents are the only tangible process acting along the northern shore.     

东亚寒潮高压的位涡诊断研究

用位势涡度方程对1980年1月26—30日东亚寒潮高压的演变做了诊断研究，表明高压中心地区低层是低值位涡区，位涡值随高压增强（减弱）而变小（变大）；随着高压的发展加强，位涡最小值由对流层中层降到近地面层，随着高压的减弱，最小值中心又上升；对流层高层的位涡值随着地面高压的增强而加大，反映高空冷槽、地面高压同时在发展。位涡收支方程各项对高压发展、减弱有着不同的作用。作用最大的是地转风水平平流项和地转偏差风的散度项，其次是地转偏差风的平流项和辐射项，扭转项和热成风偏差项均甚小，可忽略不计。
