This research examined nitrogen mineralization in the top 10 cm of soils along a vegetation gradient in Hong Kong at sites where fire has been absent for 0, 1, 3, 6 and 17 years (at the time of the study), and the relationships between N mineralization and successional development of vegetation in the absence of fire. The sites including a newly burnt area (s1), short grassland (s2), tall grassland (s3), mixed tall grassland and shrubland (s4), and woodland (s5) were selected,and the in situ core incubation method was used to estimate nitrogen mineralization. Throughout the 60-day incubation in four periods, more nitrogen was mineralized at the s3 and s4 sites, the predominantly grassland sites, which contained the highest levels of soil organic matter (sOM) and total Kjeldahl nitrogen (TKN), than the s1 site, while immobilization occurred at the s2 and s5 sites. Leaching loss decreased with successional development of the vegetation, in the order of s1 ＞ s2 ＞ s3 ＞ s4 ＞ s5. The pattern of nitrogen uptake with ecological succession was less conspicuous, being complicated by the immediate effect of fire and possibly the ability of the woodland species to extract nitrogen from the deeper *** the absence of fire for 3 to 6 years, the build-up of sOM and TKN was accompanied by active mineralization, thus paving the way for the invasion of shrub and tree species. A close relationship existed between nitrogen mineralization and ecological succession with this vegetation gradient. Inherent mechanisms to preserve nitrogen in a fire-prone environment including immobilization and uptake and the practical relevance of nitrogen mineralization to reforestation are discussed.

利用sEM、TEM和拉伸性能测试方法研究时效时间（时效温度180℃）对Al-Cu-Li合金冷轧板材微观组织和力学性能的影响。研究结果表明：实验确定Al-Cu-Li合金的最佳时效时间为15 h,此时时效处理得到的TEM图中峰值时效析出相包括δ’、T1、θ’与s’相。由合金断口形貌发现主要发生了沿晶断裂与穿晶断裂,生成了部分小尺寸韧窝。随着时效时间的增加,Al-Cu-Li合金的时效硬度先增加后降低,屈服强度和拉伸强度单调增加,伸长率单调减小。时效时间15 h下合金的硬度、屈服强度、拉伸强度和伸长率分别为142 HV、338 MPa、292 MPa和8.4%。
