【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。更多还原

【Abstract】 Thermoluminescence characterresearch by microcomputer.Thermoluminescence dose metertype FJ427A1,wascarried on 45 wild carps otoliths pickedfromBaiyangdian Marshin Hebei province and Beijing Miyun Reservoir.The re-sult indicatesthat,thereis obvious different parameter of otoliths glowcurve betweenthe above-mentionedtwo water area,such as peak height,full widthat maximum(FWHM)and peak position etc.,which mark preferable relevancetothe waterbody water quality.Inaddition,the FWHMand peak positionetc.,which mark preferable relevancetothe water body wa-ter quality.In addition,the FWHMof glowcurve,espthe second prak FMHMcould be served as biomineralogy model todistinguishthe two water area with different polluted degree.更多还原
