The aim of this study was to extract the biomass-based bottom and fly ash fractions by a three-stage fractionation method for water-soluble （H2O）, ammonium-acetate （CH3COONH4） and hydrochloric acid （HCl） fractions in order to access the leaching behaviour of these residues. Except for Mo, S, Na and elements whose concentrations were lower than the detection limits, the extractable element concentrations in both ash fractions followed the order H2O＆lt;CH3COONH4＆lt;HCl. The elements concentrations in this study were also lower than those in our previous studies, in which certain extraction stages followed the BCR extraction procedure.

作者：黄荣辉陈文严邦良张人禾 State Key Laboratory of Numerical Modeling for Atmospheric Sciences and Geophysical Fluid Dynamics Institute of Atmospheric Physics Chinese Academy of Sciences Beijing 100029 Chinese Academy of Meteorological Science Beijing 100081ecent advances in studies on the interaction between the East Asian monsoon and the ENSO cycle are reviewed in this paper. Through the recent studies not only have the responding features and processes of the East Asian winter and summer monsoon circulation anomalies and summer rainfall anomalies in East Asia to the ENSO cycle during its different stages been understood further but also have the thermal and dynamic effects of the tropical \vestern Pacific on the ENSO cycle been deeply analyzed from the observational facts and dynamic theories. The results of observational and theoretical studies showed that the dynamical effect of the atmospheric circulation and zonai wind anomalies in the lower troposphere over the tropical western Pacific on the ENSO cycle may be through the excitation of the equatorial oceanic Kelvin wave and Rossby waves in the equatorial Pacific. These studies demonstrated further that the ENSO cycle originates from the tropical western Pacific. Moreover these recent studies also showed that the atmospheric circulation and zonai wind anomalies over the tropical western Pacific not only result from the air-sea interaction over the tropical western Pacific but are also greatly influenced by the East Asian winter and summer monsoons. Additionally the scientific problems in the interaction between the Asian monsoon and the ENSO cycle which should be studied further in the near future are also pointed out in this paper.

The bottom ash and fly ash from the co-combustion of wood residues and peat at a bubbling fluidised bed boiler（296 MW） contained only quartz（SiO_2）, microcline（KAl Si_3O_8） and albite（NaAlSi_3O_8）. Thus, X-ray powder diffraction（XRD） was not useful for clarifying the difference in the release of associated heavy metals from ash matrices. In order to assess the release of heavy metals from ashes under changing environmental conditions, they were sequentially extracted and fractionated by the BCR-procedure into acid soluble/exchangeable（CH_3COOH）, reducible（NH_2OH-HCl） and oxidizable（H_2O_2/CH_3COONH_4） phases. The CH_3 COOH extractable fraction in conjunction with the total heavy metals concentrations were used to calculate the risk assessment code values for heavy metals leaching from the ash matrix. The leaching studies indicate that the heavy metals in the bottom ash and fly ash are bound to different fractions with different strengths. From the environmental and utilization perspectives, heavy metals in ashes posed different levels of environmental contamination risk. Only As in the bottom ash posed a very high risk. High risk metals were Cd in the bottom ash as well as As, Cd and Se in the fly ash.

本文主要研究胶印纸张表面分别涂布含异丙醇和无醇表面活性剂的润版液前后的物理和化学特性变化。分别采用原子力显微镜(AFM)和接触角测量仪对纸张的表面特性和表面能进行研究。用X射线电光子分光光谱(XPS)和飞行时间二次离子质谱(ToF-SIMS)研究润版液引起的纸张表面化学性质的变化。涂布纸经表面活性剂润湿后其均方根粗糙度(RMS)略有增加,但是使用异丙醇溶液却没有引起明显的变化。粗糙度发生亚微米改变的原因不仅是片基膨胀或涂层组分迁移,而且还包括表面活性剂的存在。X射线电光子分光光谱显示氧与碳的比率增加也证实了表面活性剂的存在。飞行时间二次离子质谱显示异丙醇溶液没有改变表面的化学组成而表面活性剂却很明显改变了。通过映射分子的特征碎片可以确定表面活性剂的分布。
