中国科学院云南天文台首次提出了太阳爆发过程及相应磁场结构抵近探测的科学项目,该项目将对太阳大气及发生在其中的剧烈活动进行前所未有的近距离测量。为项目研制的探测器近日区域运行时间将超过帕克太阳探测器（Parker Solar Probe, PSP）和太阳轨道探测器（Solar Orbiter）,其热防护系统遇到的困难也远超后两者。首先分析了抵近探测器的轨道环境特点,提出了热防护的设计思路,然后给出了具体热防护系统设计、仿真和地面实验方案。初步研究显示,热防护系统的设计方案具有辐射散热好、耐高温、稳定可靠等优点

The Yunnan Observatories of the Chinese Academy of Sciences has proposed a scientific project for in situ measurements of solar eruption and its corresponding magnetic field structure，which would carry out unprecedented close-range measurements of the solar atmosphere and intense activity． The total time close to the sun of Probe for in situ measurements of solar eruption will exceed the PSP and Solar Orbiter，and its thermal protection system will be far more difficult than the PSP and Solar Orbiter. This paper first analyzes the characteristics of the orbit environment of the Probe for in situ measurements of solar eruption，puts forward the design idea of the thermal protection，and then gives the design of the thermal protection system and the ground experiment scheme． Preliminary research shows that the design scheme of thermal protection system has the advantages of good radiation heat dissipation，high temperature resistance and high reliability．
