MANY geologists pay attention to Mesozoic tectonomagmatic activity and the associating multi-metal ore deposits in South China. However, the age of the transformatiori of tectonic regimein the area is little studied. Occurrence of gabbro xenoliths in Mesozoic alkaline basalts inDaoxian region, Hunan Province, shows that the lithosphere in the region was intensely ex-tended and thinned during the Mesozoic, followed by underplating of mantle-derived mag-

Cultivated Land Changes and Their Driving Forces——A Satellite Remote Sensing Analysis in the Yellow River Delta,China

Pedosphere 2004年第1期14卷 93-102页

Taking Kenli County in the Yellow River Delta, China, as the study area and using digital satellite remote sensing techniques, cultivated land use changes and their corresponding driving forces were explored in this study. An interactive interpretation and a manual modification procedure were carried out to acquire cultivated land information. An overlay method based on classification results and a visual change detection method which was supported by land use maps were employed to detect the cultivated land changes. Based on the changes that were revealed and a spatial analysis between cultivated land use and related natural and socio-economic factors, the driving forces for cultivated land use changes in the study area were *** results showed a decrease in cultivated land in Kenli County of 5321.8 ha from 1987 to 1998, i.e.,an average annual decrement of 483.8 ha, which occurred mainly in the central paddy field region and the northeast dry land region. Adverse human activities, soil salinization and water deficiencies were the driving forces that caused these cultivated land use changes.

The Analysis of Main Dosimetric glow Peaks in CaF_(2):Tm (TLD-300)

引用

Chinese Physics Letters 2013年第5期30卷 155-159页

作者： Vural E.Kafadar Metin Bedir A.Necmeddin Yazıcı Tülin günal Department of Engineering Physics University of GaziantepGaziantep 27310Turkey

The thermoluminescence properties of CaF_(2):Tm (TLD-300) are examined in detail after β-irradiation at room temperature. The glow curve of the sample shows two main dosimetric glow peaks: P3 (at ~150℃) and P5 (at ~250℃). The additive dose, variable heating rate, computer glow curve deconvolution, peak shape and three points methods are used to evaluate the trapping parameters, namely the order of kinetics (b), activation energy (E) and frequency factor (s) associated with the dosimetric thermoluminescent glow peaks (P3 and P5) of CaF_(2):Tm (TLD-300) after different dose levels with β-irradiation.

本研究考察土木工程、政治学和兽医学领域研究论文摘要中的作者提及。由于这些学科较少受到关注,我们从功能性视角在一个超百万词符的论文摘要语料库中分析显性的作者自我提及。我们首先对语料库中显性第三人称复数作者自我提及进行初步搜索,并手动分析超过6,000个实例,以检查它们是否都标记作者在文本中的自我呈现。此后再根据Xia(2018)的框架手动对自我提及的修辞功能进行分类。结果发现,政治学基于“we”的作者自我提及频率超过其他学科。关于作者自我提及的密度,我们发现每个学科都偏好于在其摘要中以不同的作者角色更加明显地出现。例如,政治学在其摘要中通过“提出理论或方法”呈现自我,而土木工程和兽医学的作者使用较少地使用这种修辞特征借以提及自我。关于“we”的自我提及的功能分析,所有三个学科都更多地显示了其降低风险功能,如“叙述实验程序和方法论”。本文突出学术语篇的跨学科和功能分析重要性,以期为每个学科设计学术用途英语(EAP)活动提出教学启示。
