| 摘 要： | 收集全国15个不同区域、不同地质环境、不同深度测点的H2浓度,以及气温、气压整点值连续观测资料,研究高精度土壤H2浓度日、月动态变化特征,通过计算H2浓度与气温、气压的相关系数,定量分析不同观测孔深气温、气压对H2浓度的影响程度。结果表明:土壤H2浓度动态变化与气象因素密切相关,观测孔优选深度为4~11 m。

| Abstract: | Continuous observation data of hydrogen levels and hourly values of air temperature and air pressure for 15 different regions,geological environments,and depths in China are collected.Daily dynamic characteristic of levels of high-accuracy hydrogen in the soil is studied and influence degree of air temperature and air pressure of different hole depths to hydrogen levels is analyzed quantitatively through the calculation of correlation coefficient of hydrogen levels and different air temperature and atmospheric pressure.The result shows that observation dynamics of levels of hydrogen in the soil and atmosphere factor is closely related and the best depth of observation hole is 4~11 m. |

| Keywords: | hydrogen in the soil air temperature air pressure dynamic characteristic influence factors |
