| 摘 要： | 重力活塞取样器是一种重要的海底连续沉积物采集仪器,贯入深度和样品质量对海洋地质研究有着重要影响。通过对重力活塞取样器贯入过程建立能量守恒方程,得出贯入深度控制方程。已知取样器参数和土质类型条件,可计算取样管贯入深度,深度受取样器重量、体积、形状、取样管直径和沉积物类型等因素共同影响。已知取样器参数和贯入深度,可推测海底沉积物类型。

| Abstract: | Gravity piston corer is an important equipment for seabed sediment collection. Penetration depth and sediment quality have important effects on marine geology study. A penetration depth control equation is obtained by building up an equation of energy conservation based on the process of gravity piston corer penetration. This equation can calculate penetration depth when corer parameters and sediment type are available. Penetration depth is affected by the dead weight, volume, shape, diameter of the corer and sediment type. It can also be uesd to speculate about the sediment type when corer parameters and penetration depth are available. |
