水底原位X射线荧光光谱分析测量装置研制

摘要

To avoid and weaken as much as possible the impact which unevenness effect acts on the underwater in-situ X-ray fluorescence spectrometry, an underwater in-situ X-ray fluorescence spectrometry assistance measurement equipment is developed.The equipment is composed of underwater video camera system and angle measurement system, and it is installed on a portable X-ray fluorescence spectrometry probe and is used to un-derwater in-situ X-ray fluorescence spectrometry.Thus the underwater measurement can effectively select the measuring surface and avoid and weaken the unevenness effect campared with the measurement on the ground. The equipment is installed combined type, and it can be used underwater with a maximum depth of 30 meters, and its angle measurement system can also be used in other places to be measured angle.Experimental results show that:the development of the measuring device solves unevenness effect underwater in-situ X-ray fluo-rescence spectrometry.%为尽可能地规避、弱化不平度效应对水底原位X射线荧光光谱分析的影响，研制了一套水底原位X射线荧光光谱分析测量装置。该装置将水下视频摄像系统与倾角测量系统组合为一体，安装于便携式X射线荧光仪探头上，用于水底原位X射线荧光光谱测量。测量时就像在地面一样能有效选择测量面，有效地规避、弱化不平度效应。该装置为组合式安装，水下使用最大深度为30 m，其倾角测量系统除用在本系统以外，也可用于其他需测量倾角的地方。实验结果表明：研制的测量装置较好地解决了水底原位X射线荧光光谱分析的不平度效应问题。
