Experimental device for preparing simulated lunar soil with low water content and H isotope composition

The invention discloses an experimental device for preparing simulated lunar soil with low water content and H isotope composition. The experimental device comprises a glove box, a lunar soil cup, a liquid nitrogen refrigeration tank, a water vapor generating device and a gas conveying pipe, the experiment steps comprise that after the temperature and humidity conditions in the glove box are stable, the liquid nitrogen refrigeration tank refrigerates a simulated lunar soil sample, water and heavy water mixed gas generated by the water vapor generation device is conveyed into the lunar soil cup through the gas conveying pipe, and simulated lunar soil composed of low water content and H isotope is prepared. The device has the advantage of being capable of simulating the formation process of the water-containing ice lunar soil in a low-temperature and near-lunar-surface environment. 本发明公开了一种低水含量及H同位素组成模拟月壤制备实验装置，它包括手套箱，月壤杯，液氮制冷罐，水蒸气发生装置及输气管;其实验步骤包括手套箱内温度、湿度条件稳定后，液氮制冷罐对模拟月壤样品制冷，通过输气管传输水蒸气发生装置产生的水和重水混合气体到月壤杯中，制备低水
