| 中文摘要: |
| 沉积物柱芯采样器是一种广泛应用于生态环境研究的科研装备.在前人研究的基础上,我们研制了一套携带方便、操作简单、适用范围广、取样效果好的湖泊沉积物茬芯采样装置.通过组件的不同组合,该采样装置可实现不同水深条件下的沉积物柱芯采样,采集的沉积物厚度可达80～150 cm.该采样装置具有体积小、重量轻、结构简单、性能可靠的特点.此外,该采样装置还配备了笸单实用的分样装置,可快速、准确的进行野外分样. |
| 英文摘要: |
| According to previous experiences in making sampling devices and some reference materials from abroad,we have developed a new-style device for taking lake sediment cores.This device may be used to collect lake sediment cores without disturbance,and the sediment-water interface can be kept distinct.The new sampling system is applicable to both deep and shallow lakes by various combination of the components.The maximum length of sediment cores increases from 80 cm to 150 cm.The practice has proved that this s... |
