1煤灰沉积的传热过程模型及其数值研究显示文摘计算流体力学(CFD)方法的应用在锅炉设计或燃烧设备的改造过程中有着十分重要的作用.本文研究了实际燃烧过程中普遍存在的煤灰沉积现象对数值计算结果的影响,提出了描述煤灰沉积的新型传热模型,比较了新模型采用前后数值计算结果与实测数据的差异,从而验证了该模型的合理性,提高了对炉内积灰、结渣过程数值描述的精度.徐明厚 郑楚光 HE X G AZEVEDO J L T CARVALHO M G 2002工程热物理学报2002,23,1:10
216年随访的前瞻性队列中521120名个体的膳食脂肪摄入与总死亡率和特定原因死亡率的关系显示文摘饱和脂肪摄入与心血管健康相关性的证据存在争议。不饱和脂肪和总死亡率及心血管病死亡率的相关性存在不一致性,并且关于非心血管病死亡率的数据较少。该文旨在评估膳食脂肪与总死亡率和特定原因死亡率的关系。方法和结果:研究者分析了来自随访16年的美国国立卫生研究院一美国退休人员协会膳食与健康研究年龄50~71岁的参与者521 120人的数据。通过食品频率问卷评估饱和脂肪酸(saturatedfatty acid,SFA )、反式脂肪酸(trans-fatty acid,TFA)、单不饱和脂肪酸(monounsaturated fatty acid,MUFA)与多不饱和脂肪酸(polyunsaturated fattyacid,PUFA)的摄入量。陈嘉睿(译) 练桂丽(审校) Zhuang P Zhang Y He W Chen X Chen J He L Mao L Wu F Jiao J 2019中华高血压杂志2019,27,4:7

6Cooperation in an asymmetric volunteer's dilemma game with relatedness显示文摘What motivates some members of a social group to voluntarily incur costs in order to provide for the common good? This question lies at the heart of theoretical and empirical studies of cooperative behavior. This is also the question that underlies the classic volunteer's dilemma model, which has been previously explored in scenarios where group members are related or interact asym- metrically. Here we present a model that combines asymmetry and relatedness, showing that the probability of volunteerism in such systems depends closely on both the degree of asymmetry and level of relatedness between interacting individuals. As has been shown in previous volunteer's dilemma models, the payoff ratio and overall group size also influence the probability of volunteerism. The probability of volunteerism decreases with increasing group size or decreasing cost-to-benefit ratio of the coplayers; in the presence of asymmetrical interactions, subordinate players were more likely to offer public goods than the dominant player. More asymmetrical interactions decrease the probability of volunteerism of the dominant player; overall volunteerism increases with increasing relatedness.HE JunZhou WANG RuiWu CHRISTOPHER X J Jensen LI YaoTang LI ChaoQian 2012Chinese Science Bulletin2012,57,16:2
