Medical geology：new relevance in the earth sciences

The interdisciplinary fieldresponds to the need to betterof “Medical Geology“ understand the relationships between human health and our surrounding environment. The influence of earth resources, natural environmental factors and land-use on human health has long been recognized, dating back to ancient Rome and Peru‘s Inca civilization. Today links between the natural environment and health can be found throughout the world. This review introduces the historical context of this particular type of research, contrasts the direct geological and indirect natural hazard influences on healthas a framework of study, elaborates on pathways of elemental accumulation in the body and provides examples of specific geochemical behaviours and diseases that are often associated with either too much or not enough of certain elements which comprise the Earth.     

卫星高度计海面高度时间距平场反演平均场的理论基础

由于卫星高度计海面高度场中含有大地水准面信息,在目前测量和计算大地水准面不甚精确的情况下,对其时间距平场的分析应成为目前使用这种资料分析海洋动力学的主要途径。本文从海洋动力学角度,从理论上阐述了时间距平场中包含着平均场的信息,从而从理论上提供了一种时间距平场反演平均场的方法。通过数值实验获得模拟的Geosat高度计资料,定量分析了时间距平场对平均场的贡献,即T内尺度内脉动量对T际尺度运动的贡献,并对上述反演方法进行了模式检验。     

渤海基底倒形结构形成机制

对在渤海中完成的四条重力测量剖面进行了重力反演计算，反演方法用的是重力测深公式加叠代修正。由于引入以深度为量纲的修正量，它可利用统一的类似甘布尔采夫量板进行计算，简便了计算方法。
