Contents of Cu, Zn, Ni, Cr and Pb increased steadily in tree-rings from the heart-wood to sap-wood at both sites, reflecting the increase in the bio-availability in the Delta area during the past decades. Peaks in Cu, Zn, Ni and most obviously Cr and Pb, were found in rings formed after 1990. It was suggested that the recent increase of the heavy metals in soil and atmosphere in the Delta was the main source contributed to the elevation of the heavy metals in the pine rings.

结果表明：西樵山马尾松林地表层土壤Cu、Zn、Cd和Pb含量均超过其在广东省表层土壤环境背景值，鼎湖山马尾松林地表层土壤除Cd外其余重金属含量在背景值范围内；鼎湖山和西樵山马尾松木质部中Cu、Zn、Cr和Pb含量均呈现从心材到边材上升的分布格局，反映了珠江三角洲环境中可供植物利用的重金属在过去有了增加。

But holdbacks are appearing in the practice of the transference from biomedical model to bio-psycho-social medical model.

然而，在旧有的纯生物医学模式向生物——心理——社会医学模式转换的实践中，其转换过程却遇到了较大的障碍。

In the first stage, anaerobic hydrogen depolarization is predominant and produced iron oxide corrosion product layer; in the second stage, due to bio-produced hydrogen sulphide, iron oxide was biomineralized and translated iron sulphide.

初期是厌氧条件下的氢去极化，生成氧化物产物层；然后在SRB代谢产生的H2S作用下，发生氧化物到硫化物的转变。

The combustion characteristics of iso-octane/diesel and ethanol/bio-diesel both show a two-stage heat release without HCCI low temperature reactions.

本文首先采用双燃料的方式，对正庚烷/柴油、异辛烷/柴油、乙醇/生物柴油这三种双燃料组合的HCCI/DI分层复合燃烧与排放特性进行深入研究和比较分析。

By timely and spatially controlling the physical and chemical characteristics of the fuel at both port injection stage and in-cylinder direct injection stage, HCCI/DI stratified compound combustion is developed to combine the advantages of HCCI and conventional DICI on cycle-to-cycle basis and achieve clean and efficient combustion at full load ranges without misfiring and knocking.Firstly, three types of dual fuel including n-heptane/diesel, iso-octane/diesel and ethanol/bio-diesel a...更多re utilized to investigate the combustion and emission characteristics of HCCI/DI stratified compound combustion. The experimental results indicate that n-heptane/diesel HCCI/DI combustion presents a three-stage heat release consisting of HCCI low temperature heat release, high temperature heat release and diesel diffusive combustion.

本文提出的基于燃料设计与管理的HCCI/DI分层复合燃烧是一种将HCCI燃烧和传统缸内直喷压燃融为一体的新型燃烧方式，通过对燃料理化特性的设计和在预喷与直喷阶段从时间尺度和空间尺度上对均质和非均质混合气制备过程的控制和管理，在发动机的一个工作循环中将均质混合气的HCCI燃烧和非均质混合气的DICI扩散燃烧相融合，彻底消除了HCCI燃烧在小负荷失火和大负荷爆震的弊病，实现了发动机全负荷范围内的高效清洁燃烧。
