基于深海大洋在地球气候系统中的重要作用,国际上陆续提出并实施了一系列以深海大洋为核心的重大研究计划,目前自沉式剖面浮标因具备高分辨率采样观测的能力,被广泛应用于对深海大洋环境的观测研究中.为了增大浮标在运动过程中体积变化范围,本文提出一种在普通APEX浮标上加装N2蓄能器的改变浮标浮力的方式,给出其工作原理图,结合其工作环境推导出浮标匀速运动时的速度方程,得出普通浮标和氮气浮标上浮运过程中的瞬时加速度以及速度随时间的变化曲线,并比较分析蓄能器对浮标上浮运动的影响.%Because of the importance of the deep ocean in the earth climate system, a series of research projects which take the deep ocean as the core have been put forward and implemented in the world. The float has been generally used in deep ocean observation research in consideration of its high-resolution observation ability. In order to broaden the variation range of the volume of the float, a new type float named N2float which is equipped with N2energy accumulator basing the normal APEX float has been devised. The schematic diagram of this float would be proposed. The formulation of the uni-form motion of the float would be given by doing mechanical analysis, and the volume of the float needed for floating would be calculated, the figures of accelerated velocity-time history and velocity-time history of the normal type and new type float would be deduced, the figures would be compared and the influence of the energy accumulator would be analyzed.
