基于消费者效用的电商供应链企业的产品质量和服务策略研究

基于消费者效用理论，将消费者参考质量效应和线上渠道接受程度的影响纳入到电商供应链（ECSC），利用微分博弈理论和连续型动态规划理论研究了制造商或零售商拥有线上开辟权两种渠道结构下的制造商质量策略和零售商产品服务策略.发现：于拥有线上渠道开辟权的ECSC企业而言，其线上渠道的开设与否与消费者对线上渠道接受程度有关.数值算例对关键参数进行了敏感性分析，发现：1）制造商拥有线上渠道开辟权并以线上线下混合渠道销售可为消费者提供更高的产品质量并激励零售商的线下服务水平，为企业带来更高的品牌商誉.2）于企业各自利润而言，对方开辟线上渠道对自身更有利；于供应链整体而言，零售商线上线下混合的销售模式更有利于长远发展.3）提高消费者对线上渠道的接受程度，以线上渠道销售为主，线下服务为辅，降低消费者参考质量效应对供应链运营各方面的负向影响是企业的长久运营之道.     

苯乙烯甲基丙烯酸甲酯高温共聚合反应的研究

本文研究了苯乙烯和甲基丙烯酸甲酯的高温共聚合反应。由实验得出,200℃时的共聚合体系(r_1=2.76,r_2=0.35,r_1×r_2=0.97)接近于理想共聚(r_1×r_2=1),还得出,高温条件下二者的共聚合的解聚反应是相当可观的。     

A stress-sensitive reporter predicts longevity in isogenic populations of Caenorhabditis elegans

When both genotype and environment are held constant, 'chance' variation in the lifespan of individuals in a population is still quite large. Using isogenic populations of the nematode Caenorhabditis elegans, we show that, on the first day of adult life, chance variation in the level of induction of a green fluorescent protein (GFP) reporter coupled to a promoter from the gene hsp-16.2 predicts as much as a fourfold variation in subsequent survival. The same reporter is also a predictor of ability to withstand a subsequent lethal thermal stress. The level of induction of GFP is not heritable, and GFP expression levels in other reporter constructs are not associated with differences in longevity. HSP-16.2 itself is probably not responsible for the observed differences in survival but instead probably reflects a hidden, heterogeneous, but now quantifiable, physiological state that dictates the ability of an organism to deal with the rigors of living.     

运动偏心对圆光栅副测量的影响及误差补偿

研究了一种由长光栅演变而来的新型圆光栅副存在运动偏心时的正常工作条件和由运动偏心所造成测量误差的补偿方法.阐述了该圆光栅的组成结构和工作原理; 推导了其莫尔条纹曲线的表达式; 着重研究了运动偏心对圆光栅测量影响的分析方法,即莫尔条纹随运动偏心变化的定量分析方法; 推导了由于偏心引起的测量误差的补偿公式; 通过实例分析证明,对精密测量圆光栅进行偏心误差补偿是十分必要的.研究结果表明,偏心较小时,由于不影响系统正常工作,因此会掩盖这种误差的存在,通过理论分析及补偿可确保这种新型圆光栅的测量精度.

2＋1维U（1）格点规范理论的相图

应用单元格试探作用量变分法研究2 1维U(1)格点规范场的相图。解析地计算出序参量——平均元格能量,与MC方法所得结果符合很好。证实2 1维U(1)格点规范理论是禁闭的。消除了以往文献中用单链试探作用量变分法出现的不正确的一级相变点,还可以很方便地计算到比MC方法的β更大的深度弱耦合区。     

Protection efficacy of national wetland reserves in China

Wetlands have the most abundant biodiversity,the highest carbon sequestration capacity,and the highest values for ecological services per unit area,of all the world’s ecosystems.Practice has shown that establishing reserves is the most effective way of protecting typical ecosystems and their biodiversity,and saving rare or endangered wildlife.The Chinese government’s policy is to protect wetland systems by establishing reserves that encompass a massive network of wetlands,including wetland nature re-serves,internationally important wetlands,and wetland parks.Many are already established.The effect of protecting wetland nature reserves at the national level has not yet been reported.We used the latest database evaluating the protection value of wet-land reserves,and remotely sensed wetland maps(1978-2008) ,developed by the same mapping specialists and based on the same classification system,and related environmental data,to evaluate the effects of protecting China’s national wetland reserves over the last 30 years.We conclude that(i) the total area of wetland in the national wetland reserves has decreased over the last 30 years to 8152.47 km2,and just 8% of China’s net decrease in wetlands;(ii) about 79% of the 91 national wetland reserves are in a poor condition.These are generally located around the Yangtze River,Eastern Coast,the Three Rivers Source,and Southwest China.Protection measures should be undertaken urgently in these areas.Only 15% of national wetland reserves are under sound protection,and these are generally located in the upper reaches of the Songhua River;(iii) although 88% of national wetland re-serves are primitive(relatively natural) ,implying that the site selection has been scientific,a high percentage of national wetland reserves show early warning signs of decline and require urgent attention;(iv) based on our evaluation of protection effects and pressures on ecology,we have made a priority list of national wetland reserves,and propose several protection strategies.
