政府保持清正廉洁是构建和谐社会的重要因素。美国政府已经基本形成一个相对完整的政府行政伦理体系。而其体系的建构则经过了上百年的历程,是由他律转变为自律的过程。美国政府道德规范体系的构建经验对中国有一定的借鉴意义。

Remote-mode microsphere nanoscope can observe the nano-structures with 23 nm feature size. It does not require samplepreparation and functions in both ambient air and liquid environments. Compared with the scientific characterizationtools listed in Table S1, the simple and portable nature makes the microsphere nanoscope a favorable solution forgeneral purpose imaging in practical fields, like hospitals, food industry, semiconductor production lines, schools andenvironment agencies.

Background The consumption of carbohydrate-electrolyte beverages （CEs） has been known to be more effective than plain water for recovery from dehydration. This phenomenon suggests that the ingestion of CEs after dehydration is better than water for maintaining body fluid and plasma volume, and for the recovery from hemoconcentration and high blood viscosity as well. High blood viscosity causes infarction and other cardiovascular events. In this study, CE was compared with water and tea for the ability to reduce increased blood viscosity after dehydration. Methods A crossover random control study was conducted to assess the effectiveness of three beverages for rehydration and decreasing of blood viscosity. Following exercise-induced dehydration of 2.2% of body weight in a permanent warm environment, 10 male subjects rested in a thermoneutral environment for 3 hours （rehydration period, REP）. The subjects ingested test beverages equal to their body weight loss during the first 20 minutes in REP. Blood and urine samples were obtained throughout the experiments to assess the rehydration effect. Results The change in blood viscosity at a shear rate of 5/s was significantly lower in CE （（-1.66±0.21） mPa.s） in comparison to water （（-0.95±0.26） mPa.s） or tea （（-0.92±0.14） mPa.s） at 60th minute during the REP. The fluid retention rate was significantly greater for CE （（77.0±3.9）%） than water （（61.2±3.4）%） and tea （（60.5±3.7）%） for 3 hours of rest in REP. Conclusions The recovery from high blood viscosity induced by dehydration was higher with CE consumption than with water or tea. These results suggest that CE is useful for normalizing increased blood viscosity due to exercise-induced dehydration.

Background We managed to assess and confirm the risk factors for mortality after coronary artery bypass grafting （CABG） operations so as to map out the proper guidance of surgical strategy especially in patients with low left ventncular ejection fraction （LVEF） in domestic polyclinic like ours. Methods Five hundred and forty-eight consecutive patients underwent CABG from December 1999 through August 2005 were analyzed retrospectively. Eighty-nine cases had an LVEF of 40% or less. All together twenty-two candidate factors were evaluated for their association with perioperative death using univariate and multivariate stepwise Logistic analysis. Results When data from all the patients who had undergone CABG were taken into account, LVEF, left ventricular end diastolic diameter （LVEDD）, mitral regurgitation, aneurysm of the heart wall, mitral repair/replacement, resection of aneurysm, concomitant aortic valve replacement, and perioperative intra-aortic balloon counter-pulsation （IABP）, left ventricular assist device （LVAD） and cardiopulmonary bypass （CPB） all showed an association with perioperative death in univariate analysis, while an LVEF of 〉40%, on the other hand, appeared to be a protective factor. In multivariate analysis, moderate to severe mitral regurgitation, aneurysm of the heart wall, repair of septal perforation and aortic regurgitation were proved to be risk factors. When the analysis was restricted to patients with an LVEF of 40% or less, such variables as age, LVEDD, mitral regurgitation, mitral repair/replacement, IABP, and CPB were qualified as risk factors in a univariate analysis. Age, moderate mitral regurgitation, aneurysm of the heart wall, CPB, left main coronary artery disease and female were associated with pefioperative death in a multivariate logistic regression analysis. Conclusions Concerning the prognosis, patients who undergo CABG would have different risk factors when data from all the enrolled patients or data from patients with

发汗式主动冷却金属热防护系统是一种新型概念,将发汗冷却方法应用于金属热防护系统中,用于提高金属热防护系统的热载荷承载能力,是解决临近空间高超声速飞行器防热问题的有效方法。设计并建立了发汗式主动冷却金属热防护系统的实验模型,分析了发汗式主动冷却金属热防护系统的基本冷却原理,测量了同一实验模型分别在有无发汗冷却作用下,沿厚度方向不同位置测量点的温度响应。结果表明:在相同的加热条件,采用发汗冷却方法,可以使受热蒙皮材料达到相同温度的时间明显滞后;在发汗冷却作用的过程中,内部隔热层的温度不会超过水的沸点温度;采用发汗冷却方法,可以使同一结构热载荷承载能力至少提高70%;通过合理的结构设计,可以减少受热蒙皮由于热膨胀而引起的结构变形。

青年时代李叔同与他同时代青年才俊所不同的是,他深刻地意识到:传播新思想、新理念,必须要充分利用中国传统音乐的自身艺术魅力。他本着"乐失求诸野"的觉悟,将自己的眼光落在了活跃在上海的乐籍群体身上。他的这种做法,使得李叔同成为近代中国音乐历史上第一位以"局内人"的意识进行传统音乐采风的实践者。而这种定性,恰是当代中国音乐史学界的同仁所忽视的。长期的"局内人"的民间音乐采风实践,使他获得了丰富的中国传统音乐的感性认识,也加深了其在少年阶段获得的音乐文化典籍的理性认识。新见的《李苹香·序言》是未被《弘一大师全集》收入的文献,也是长期被史学界忽视的文献。通过对该文献的解读,可以解除学界对其青年时期音乐活动的一些误解。
