【摘要】 在对湖泊或水库等浅层水域的环境变化研究和环境污染检测中,浅层水域的淤泥质沉积物取样是一项必不可缺的工作。在综合比较国内外常用重力取样器优缺点的基础上,提出了一种能够获取水库、湖泊等水域浅层淤泥质原状沉积物的重力式取样器,并详细介绍了其工作原理及其各组成机构的功能。通过现场试验情况证明,该取样器具有结构简单、操作方便的优点。更多还原

【Abstract】 It is very essential in the study of environmental change and pollution monitoring to sample the undisturbed sediment from shallow water areas,such as lakes and reservoirs.This paper presents the development of a portable gravity sampler for this sampling purpose by means of comparison and comprehensive analysis of several domestic and foreign sediment samplers.It also introduces the working principle and the function of each component.The in-situ tests prove that the portable gravity sampler is simple in structure and easy for operation.更多还原
