摘要: 化学物质释放是空间物理主动试验的重要手段之一.构建了一种基于探空火箭平台的SF₆气体释放装置，其具有体积小、自重轻、对运载平台要求低等优点，当装置自身质量为6kg时可实现2kg的SF₆气体释放.仿真计算了SF₆气体在电离层高度的扩散过程和相应的电离层离子化学过程.研究结果表明，本装置能够有效消减电离层电子密度，具有较高实用价值.

Abstract: Chemical release at ionospheric altitudes is one of the most important ways to carry out active experiments for investigation of ionosphere features. A new rocket-borne SF₆ releaser is studied. This releaser has many advantages such as small size, light weight, low requirements for the launch platform, and when the device weight is 6kg, 2kg SF₆ can be released. By means of simulation, the diffusion process of neutral gas and relevant chemical reactions in ionosphere are calculated, and the effect of SF₆ releases is investigated．Results showed that the designs scheme of the SF₆ releaser is feasible and consistent with domestic rocket-borne platform and conditions in China, hence has high application value.
