低能区的16O+12C散射折叠模型研究

基于^12C和^16O原子核的α粒子结构，利用α粒子折叠模型对较低能区的^16O＋^12C弹性散射进行了研究计算。计算结果表明，α粒子折叠模型能较好地描述低能区的^16O＋^12C弹性散射角分布实验数据。折叠模型光学势的虚部对小射角区影响很小，但对大射角区的截面计算有一定的影响。     

解读“节约型政府”

建设节约型政府是当前我国政府改革的必然要求。节约型政府模式的选择有其必然性。节约型政府应是廉价政府、廉洁政府、透明政府和效益政府。应通过加强节约型政府的制度建设、在行为方面加强政府自身建设、在各级政府中牢固树立节约理念和成本意识等措施全力，打造节约型政府。     

数字电视技术现状及发展前景

近年来,数字电视已经成为广播电视业界和消费者关注的热点,而且开始走进人们的日常生活。但人们对于数字电视的认识还存在很多的局限性,因此本文对数字电视及其发展现状和发展前景作了系统介绍,并且提出了几种下一代数字电视的技术发展方向。     

The Difference of the Pulmonary-Artery Pressure of the Migrants from Difference Elevation at the 4636 - 4907 m Altitude

Study Objective： To compare and analyze the changes of the pulmonary-artery pressure of the migrants coming from different elevation in the hypoxic environment of 4636 - 4907 m extreme altitude. To explore the susceptibility to hypoxic pulmonary-artery hypertension （PH） in the subjects from different altitude and profession. Methods： By using Color Doppler Ultmsonography （CDU）, measuring the pulmonary-artery pressure of 207 healthy men, who had continuously being lived and worked at the extreme altitude for more than six months, and then were divided into three groups according to their profession and the altitude of original living place. Results： There was a significant difference in the outcomes of pulmonary-artery pressure from the 3 groups. Conclusions： Altitude of original living place, labor intensity are some of factors that impact the pulmonary-artery pressure of the people who exposure to a hypoxic environment. The pulmonary- artery pressure of person without strenuously physical work experience was more sensitive to hypoxic surroundings than that of labor workers. It was not always the fact at an extreme altitude that the moderate altitude mountaineers were superior to other migrants from a lower altitude or plain. The higher PH was found in the groups of the moderate altitude mountaineers and labor workers. It is unlikely certain that one with PH would surfer from HAPE.

当代文学＂民间＂研究的旧问题与新思考

20世纪90年代中期以来,知识分子民间立场、民间文化形态、民间审美形态、民间隐形结构等一系列学术范畴的建立,突破了文学史叙述在知识分子/政治意识形态、传统/现代等二元结构上的局限,拓展了文学研究的多维文化空间.     

区域资源空间分配的数学原理

文章根据经济学的择扰分配原理和区域经济地理学的区划思想，提出资源在地域空间上合理配置的数学规划方法，并指出了应用此方法的有关问题及解决办法。在探讨方法论的同时，文章也得出如下结论：资源的空间分配法则不是域均衡，而是边际收益的空间统一。

Functional magnetic resonance imaging of amphetamine craving

The aim of this study is to identify the brain activity associated with amphetamine craving for understanding the neurobiology of addiction by watching pictures of happy, sad or amphetamine. Brain activity was measured in 12 amphetamine addicts and 12 healthy subjects by fMRI while the subjects watched pictures designed to elicit happy feelings, sad feelings, or the desire to use amphetamine. The result demonstrated that amphetamine cues led to abnormally high cingulate and low frontal lobe activation in amphetamine addicts, who showed abnormalities in affect-related brain activation.
