| 摘要: |
| 木星冰卫星（尤其是“木卫2”）在整个太阳系中有非常独特的探测价值，也是当前国际深空探测最前沿、最受关注的领域之一。在对国外相关探测技术归纳总结的同时，结合木星冰卫星冰下海洋探测的若干科学问题，次表层模型、温度廓线及探测深度、电离层的影响等方面，提供了几种木星冰卫星冰下液态水海洋探测的新思路，并给出了一些初步的系统框架设计和次表层介电特性仿真分析等结果。通过对新方法、新模式的探索，有望对我国自主木星冰卫星的次表层液态海洋探测起到良好的借鉴作用。 |

| Abstract: |
| Icy Moons of Jupiter System (especially Europa) have abundant exploring value,and they are among the hottest objectives in solar system exploration throughout the world. In this paper,the recent advances in pertinent exploration technology in the international community are summarized, and some science issues, such as sub-surface model, temperature profile, penetration depth,and the influence of icy moons' ionosphere,are addressed. A few new ideas are presented,a preliminary system framework is proposed,and some simulation results of the sub-surface dielectric property are shown. The forthcoming Chinese autonomous Jupiter system exploration mission focusing on the exploration of the liquid oceans beneath the icy moons' surfaces is expected to benefit much from the investigation of new methodology and new configuration in this paper. |
