摘要: 研究了红外光辐射诱导氘氘(DD)固体空间分布变化的内在机理,探讨了红外光波长和辐射时间对固体冰层空间分布变化和结构的影响.研究表明:在特定波长红外光的辐射加热作用下,DD固体冰层的结构呈现出由多晶向单晶变化的趋势,其空间分布变得均匀、透明.有效的红外光加热波长为3140 nm,在其输出功率为100μW时,DD固体的再分布时间约为18 min.Abstract: In this paper,the internal mechanism of solid deuterium spatial distribution induced by infrared radiation is studied.The changes in spatial distribution and micro-structure of solid deuterium are also discussed as the results of wavelength and heating time of IR light.It is found that the micro-structure of solid deuterium which is irradiated by a special IR light is changed from polycrystal to monocrystal,the solid deuterium is redistributed and becomes more uniform and transparent.The best wavelength of IR light for heating solid deuterium is 3140 nm.When the output power of 3140 nm IR light is 100 uW,the redistribution time of solid deuterium is about 18 min.
