论中国古代绘画“形”“神”兼重的思想

中国古代绘画＂形＂＂神＂兼重的思想可分为三个阶段：汉朝时期为＂形＂＂神＂兼重绘画思想的提出时期,魏晋南北朝时期为＂形＂＂神＂兼重绘画思想的发展时期,唐朝时期为＂形＂＂神＂兼重绘画思想的深化时期。     

从《齐民要术》看南北朝的素食

素食是中国烹饪百花园中的一朵奇葩,历史悠久,别具一格,如今又因其合于健康、绿色的时代潮流。受到越来越多人士的关注和推崇。而中国素食在漫长的历史发展过程中,南北朝时期是一个十分重要的阶段,贾思勰的《齐民要术》对此做了科学、真实而详细的记载。通过贾思勰《齐民要术》“素食”篇及其他相关记载,可以比较全面、系统地窥探出南北朝时期素食发展的主要状况,阐明它不仅是后世研究中国素食发展历史的十分珍贵的史料,更是中国素食风味体系初步形成的重要标志。     

Mapping lichen in a caribou habitat of Northern Quebec, Canada, using an enhancement_classification method and spectral mixture analysis

Studies of caribou herds in northern regions are important to better understand population dynamics and define wildlife management strategies. Lichen is a primary food source for caribou and is a good indicator of caribou herd activity because of its sensitivity to overgrazing and overtrampling, its widespread distribution over northern areas, and its influence on herd demography. In this paper, we used Landsat TM imagery for mapping lichen in the summer range of the George River caribou herd in northern Quebec, Canada. Results from the enhancement_classification method (ECM) and from spectral mixture analysis (SMA) were evaluated for their suitability to characterize lichen landcover and for their potential to be applied over large territories. ECM and SMA are assessed individually, and also for potential synergistic use. ECM is based on guided unsupervised classification of enhanced satellite images. Validation based on 3536 pixels from a relatively smaller number of field sites (20) showed an overall accuracy of 74.5% (kappa=0.70) for 10 classes and good discrimination between lichen and non_lichen classes, though we interpret these results with caution due to spatial autocorrelation and non_random sampling within field sites. However, discrimination amongst different lichen classes using ECM was more problematic. SMA derives the proportion of individual scene components at sub_pixel scales. This method provided good results in characterizing variations in lichen abundance validated against field observations, and provided additional and new information not provided by ECM which is important since the abundance of lichen as a primary food source is a key indicator of migration and demographic patterns essential for effective wildlife management. We concluded that the ECM and SMA methods are appropriate for different aspects of lichen mapping. ECM provided good discrimination between lichen and non_lichen classes whereas SMA provided additional lichen information not available by classification yet critical to the environmental application, which is also appropriate for application over much larger areas and in spatio_temporal studies. A synergistic use of SMA and ECM is therefore recommended for future research.

依据断裂规模及其控制作用,划分出一级控盆、二级分区、三级控带、四级控圈和五级小断裂,各级断裂有机组合,构成四大断裂系统：赛什腾断裂系统、大红沟断裂系统、昆特依断裂系统和中部断裂系统。大断裂控制了柴北缘深浅层的构造格局,形成了南北成带、东西分块、洼隆相间、上下分层构造格架。中、下侏罗统地层的展布明显受侏罗纪基底大断裂的控制。柴北缘发育七种类型的构造发育模式：断裂反转—基底逆冲—反冲断滑构造发育模式;地层反转—冲起—断滑褶皱叠加模式;断层反转-冲起滑褶皱叠加构造模式;断层反转—顺冲断滑褶皱叠加模式;断层反转—基底逆冲—断滑褶皱叠加模式;潜伏断展背斜发育模式;断层反转—反冲断滑褶皱叠加模式。断裂是控制本区油气分布的主要控制因素。基底大断裂控制着烃源岩的展布;油气藏的重要聚集空间—构造圈闭的形成与分布也受断裂控制,断裂是油气运聚成藏的最重要的通道。     

苏北-南黄海盆地裂变径迹与中古生代烃源岩受热演化

通过研究苏北盆地滨海隆起、盐城/海安/白驹/高邮/洪泽/金湖等凹陷不同地质时代裂变径迹及南黄海盆地崂山隆起地震资料,进行中、古生代烃源岩受热演化对比研究。结果表明：滨海隆起抬升于38～15Ma,具有“构造抬升模式”特征,其中,古生界烃源岩与崂山隆起一样具有“不同层等熟、不同层同温”现象;各凹陷区具有“长时加温模式”特征;新生代沉积剥蚀2km。崂山隆起中、古生界沉积逾万米,构造演化可类比于滨海隆起;根据二次生烃模拟的成果,认为崂山隆起中、古生界烃源岩具有良好的成烃-成藏潜力,有望成为海域油气勘探的一个重要新领域。     

Political violence and child adjustment in Northern Ireland: Testing pathways in a social–ecological model including single-and two-parent families.

Moving beyond simply documenting that political violence negatively impacts children, we tested a social–ecological hypothesis for relations between political violence and child outcomes. Participants were 700 mother–child (M = 12.1 years, SD = 1.8) dyads from 18 working-class, socially deprived areas in Belfast, Northern Ireland, including single- and two-parent families. Sectarian community violence was associated with elevated family conflict and children's reduced security about multiple aspects of their social environment (i.e., family, parent–child relations, and community), with links to child adjustment problems and reductions in prosocial behavior. By comparison, and consistent with expectations, links with negative family processes, child regulatory problems, and child outcomes were less consistent for nonsectarian community violence. Support was found for a social–ecological model for relations between political violence and child outcomes among both single- and two-parent families, with evidence that emotional security and adjustment problems were more negatively affected in single-parent families. The implications for understanding social ecologies of political violence and children's functioning are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Methane Adsorption Characteristics of Lower Paleozoic Shale in China's Southern Sichuan and Northern Yunnan

The study into the methane adsorption properties of three formations of shale collected from the Lower Paleozoic strata in the research area indicates the following conditions: TOC content is an important factor in controlling the methane adsorption capacity of shale; the total content of clay minerals and the theoretical maximum methane adsorption capacity of shale have no significant correlation; when TOC content varies, control over methane adsorption capacity varies widely, revealing that the adsorption capacity of shale is affected by the amount and type of organic matter and may also be restricted by other macro conditions and microfactors.
