【摘要】：金星是类地行星,被称为地球的"姊妹星",已发现其上有风沙地貌存在。理论模型分析及风洞实验研究均证明,金星具备风沙地貌的形成条件,风力作用是塑造金星地貌形态的重要外营力。金星表面环境下的风洞模拟实验生成了不同类型的风沙床面形态。对探测器返回的金星影像分析表明,金星风沙地貌主要包括沙丘和雅丹,没有明确的证据表明风棱石的存在。在无法获取高分辨率影像的情况下,对金星风沙地貌的深入研究主要依靠理论模型与风洞实验研究。此外,基于地球风沙地貌的类比研究,也成为金星风沙地貌研究的一种重要手段。
[Abstract]:Venus, the Earth-like planet known as Earth's sister star, has been found to have windy landforms. Theoretical model analysis and wind tunnel experiments prove that Venus has the conditions for the formation of wind-sand geomorphology and wind force is an important external force in shaping the geomorphological form of Venus. Wind tunnel simulation experiments on Venus surface produced different types of sand bed surface morphology. The analysis of the Venus image returning from the probe shows that the wind-sand geomorphology of Venus mainly consists of sand dunes and Aden, and there is no clear evidence of the existence of eolian rocks. Under the condition that high resolution image can not be obtained, the deep research on the wind-sand geomorphology of Venus mainly depends on the theoretical model and wind tunnel experiment. In addition, the analogical study based on the geomorphology of the Earth's wind and sand has also become an important means for the study of the wind-sand geomorphology of Venus.
