| 摘 要： | 原油污染是海洋生物和环境安全的主要威胁之一,检测近海沙粒中的微量原油对于环境保护和原油勘探有着重要意义.本文采用反射式太赫兹时域波形对近海沙粒中的原油进行定量检测,详细地分析了延迟时间与沙粒中的原油浓度的关系.结果表明,原油浓度与延迟时间呈线性递减关系,反射式太赫兹时域波形是一种具有潜力的污染定量检测方法.

| Abstract: | The contamination of crude oil in the sea is a major threat to marine organism and the environment safely. The detection of crude oil in the sand near the sea is of significance to petroleum exploration and environmental protection. Reflected terahertz time-domain spectroscopy is used for the quantitative detection of the crude oil in the sand. A detailed analysis is performed about the delay time and wave velocity across the sample. The research indicates that the relationship between the crude oil concentration and the delay time shows linear decrement character, the reflected terahertz time-domain spectroscopy is a potential method for quantitative detection in the environmental protection. |
