Abstract	本发明涉及海洋磁学研究的技术领域，公开了一种海底柱状取样技术的磁补偿测试装置及其磁补偿方法，装置包括旋转台，所述旋转台的顶部可放置有海底沉积物柱状取样器，所述取样器上安装有磁方位仪，所述旋转台能够带动取样器在水平面上绕自身转动，并调节取样器在竖直面上的放置角度；本发明针对垂直式旋转搭台体积大重量大，制作成本高，运维难度大等缺点，基于磁方位仪的工作原理和实验数据，提出了将海底沉积物柱状取样器倾斜放置以进行磁补偿校正的创新性技术，并相应改良出有效可行的磁补偿测试方案；本发明制作成本低、运维简单，安全可靠、具有重要的推广应用价值。
Other Abstract	The invention relates to the technical field of marine magnetic research, and discloses a magnetic compensation testing device of a seabed columnar sampling technology and a magnetic compensation method. The magnetic compensation testing device comprises a rotary table, wherein a seabed sediment columnar sampler can be placed at the top part of the rotary table, a magnetic azimuth instrument is mounted on the sampler, and the rotary table can drive the sampler to rotate around the rotary table on the horizontal plane and adjust the placement angle of the sampler on the vertical plane. Aiming at the defects of large size, heavy weight, high manufacturing cost, high operation and maintenance difficulty and the like of a vertical rotary building table, the invention provides an innovative technology for obliquely placing the seabed sediment columnar sampler for magnetic compensation correction based on the working principle and experimental data of the magnetic azimuth instrument, and correspondingly improves an effective and feasible magnetic compensation test scheme; and the magnetic compensation testing device is low in manufacturing cost, simple to operate and maintain, safe and reliable, and has important popularization and application values.
