Study on the Coring Technique with Gravity Piston Corer

重力活塞取样器取样技术研究

On this base, a low-disturbing sampling module for the gravity sampler and the piston corer, in which the infection of the dust harass due to the contact corer can be quantified based on the known data.

在此基础上分析了重力取样器和活塞取样器的低扰动取样模型；根据已有的一些资料数据量化描述了接触取样中取样器对土体扰动的影响；

A method of coring with a gravity piston corer from the very shallow sea ( depth < 4. 0m) on a fishing boat is introduced in this paper.

介绍了在小渔船上利用量力活塞取样管于极浅水域（水深浅于4.0m）采取柱状样的一种方法。

Sampling technique of piston gravity corer

重力活塞采样器海上采样技术的研究

A core 17.11 m long was successfully collected in an offshore experiment area with the newly designed corer, and the sampling rate achieved 91.3%, which created a collected core length record with the gravity piston corer in Chinese offshore geologic surveys.

海上实验在特定海区成功的获取了17.11m的长岩芯，取样率达91.3%，创造了我国海洋地质调查用重力活塞取样器获取岩心的最长记录。
