Water and other volatiles are present in the permanently shadowed region of the moon. Quantitative analysis of the content is of great significance for lunar resource assessment and geological evolution. However, no detector has yet carried out in situ analysis on the moon, and quantitative sampling and low-power thermal extraction of lunar regolith are also difficult. Thus, a systematic method is proposed to realize quantitative sampling & low power thermal extraction of lunar regolith that detects the abundances of volatiles more accurately. Considering the requirements of the amount and particle size of the regolith, a sampler with a specific structure and motions is designed to quantitatively collect some lunar regolith. After that, induction heating is applied to heat the sampler and indirectly increase the temperature of the internal lunar regolith for volatile thermal extraction. The results demonstrate that this sampling method can achieve high-quality quantitative sampling. Moreover, the sampler and sampled regolith can be heated to the desired temperature with low power consumption. This work offers a feasible solution for the lunar volatile exploration of Chang’E-7.

用于月球挥发物勘探的月球风化层的定量采样和热提取：方法和验证

月球永久阴影区域存在水和其他挥发物。其内容的定量分析对于月球资源评估和地质演化具有重要意义。然而，目前还没有探测器对月球进行原位分析，对月球风化层的定量采样和低功率热提取也存在困难。因此，提出了一种系统方法来实现月球风化层的定量采样和低功率热提取，从而更准确地检测挥发物的丰度。考虑到月面风化层数量和粒度的要求，设计了具有特定结构和运动方式的采样器，用于定量采集部分月面风化层。之后，采用感应加热对采样器进行加热，间接提高月球内部风化层的温度，以进行挥发性热提取。结果表明，该采样方法能够实现高质量的定量采样。此外，采样器和采样风化层可以以低功耗加热到所需温度。该工作为嫦娥七号月球挥发物探测提供了可行的解决方案。
