【摘要】 冰芯微粒的研究对反映大气粉尘变化具有重要意义。根据雪冰样品的特点,为寻求一种更便捷更适合的微粒检测方法,选择AccuSizer 780A光学粒径检测仪并尝试将其应用于冰川微粒的分析研究。通过对新疆天山1号冰川的大量雪冰样品微粒的检测分析,结果表明AccuSizer 780A光学粒径检测仪可满足冰川微粒研究的需要。更多还原

【Abstract】 tudy on microparticle in ice cores is very important because it can reflect the change of the atmospheric dust loading.Based on the characteristics of snow-ice samples,the “AccuSizer 780A Optical Particle Sizer ”apparatus is choosed,and is used for the first time to analyze the microparticle in snow-ice samples retrieved from Glacier No.1 at the Urumqi river head,Tianshan Mountains,Xinjiang,in order to obtain a convenient and helpful analytical method of microparticle in ice cores.The experimental results show that the apparatus can satisfy the need of the microparticle research in ice cores.更多还原
