【摘要】：回顧小行星熱物理研究中兩種熱物理模型TPM(thermal physical model)和ATPM(advanced thermo physical model),討論了其科學(xué)應(yīng)用及適用范圍,分析了其在未來小行星探測任務(wù)中可能的工程應(yīng)用價值�；赥PM可推算小行星的表面熱慣量性質(zhì),利用ATPM不僅可以研究小行星的表面熱慣量與表面粗糙度等特性,還能深入研究小行星的YORP效應(yīng)(Yarkovsky-O'Keefe-Radzievskii-Paddack effect)。研究表明,在目前的觀測精度下,TPM和ATPM均可有效研究并揭示小行星基本熱物理性質(zhì)。
[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.
