【摘要】：回顾小行星热物理研究中两种热物理模型TPM(thermal physical model)和ATPM(advanced thermo physical model),讨论了其科学应用及适用范围,分析了其在未来小行星探测任务中可能的工程应用价值。基于TPM可推算小行星的表面热惯量性质,利用ATPM不仅可以研究小行星的表面热惯量与表面粗糙度等特性,还能深入研究小行星的YORP效应(Yarkovsky-O'Keefe-Radzievskii-Paddack effect)。研究表明,在目前的观测精度下,TPM和ATPM均可有效研究并揭示小行星基本热物理性质。
[Abstract]:In this paper, two thermal physical models, TPM (thermal physical model) and ATPM (advanced thermo physical model), are reviewed, and their scientific application and application scope are discussed. The possible engineering application value of these models in the future asteroid exploration mission is analyzed. Based on TPM, the surface thermal inertia properties of asteroids can be calculated. ATPM can not only study the surface thermal inertia and surface roughness of asteroids, but also study the YORP effect of asteroids (Yarkovsky-O'Keefe-Radzievskii-Paddack effect). It is shown that both TPM and ATPM can effectively study and reveal the basic thermal physical properties of asteroids under the present observation accuracy.
