摘要
利用FJ427A1型微机热释光剂量仪对采自河北白洋淀及北京密云水库的45尾野生鲤鱼的鱼耳石进行热释光特征研究。结果表明,以上两个不同水域鱼耳石的热发光曲线的峰高、半高宽、峰位等参数均存在明显差异,与水体的水质特点呈较好的相关性。此外,热释光半高宽,尤其是第二峰半高宽可以作为区分两个不同污染程度水域的生物矿物学标型。
Thermoluminescence character research by microcomputer. Thermoluminescence dose meter type FJ427A1, was carried on 45 wild carps otoliths picked from Baiyangdian Marsh in Hebei province and Beijing Miyun Reservoir. The result indicates that, there is obvious different parameter of otoliths glow curve between the above-mentioned two water area, such as peak height, full width at maximum（ FWHM） and peak position etc., which mark preferable relevance to the water body water quality. In addition, the FWHM and peak position etc., which mark preferable relevance to the water body water quality, in addition, the FWHM of glow curve, esp the second prak FMHM could be served as biomineralogy model to distinguish the two water area with different polluted degree.
