The semiquantitative analysis of hydrogen gas relative to other gas constituents was done by a gas chromatographic separation equipped with a thermal conductivity detector. The hydrogen gas evolution was found to occur when the thermally annealed quartz particles were exposed with artificial radiations as well as the application of newly pulverized quartz powder. The increasing tendency of hydrogen gas was remarkably promoted from both the employment of ultrasonic agitation and larger specific surface areas of quartz and glass powder. It is noteworthy that theetching treatment of the surface with HF-solution brought on a meaningfully decreased hydrogen gas evolution whether with or without radiation exposure. From these results, the role of the surface portion was considered to be most important in the process of the radical formation and storage. Even in the case of radiation exposure. Applications of hydrogen gas evolution to geological phenomena have been discussed.", "subitem_description_type": "Abstract"}]}, "item_7_full_name_3": {"attribute_name": "\u8457\u8005\u5225\u540d",
