Abstract: 对中国传统文化和西方文化中的诚信构建和维系力进行了分析,提出不同社会文化背景中的医患 诚信观念的构建和维系力与本底文化有一定的关系。进而论证在我国当下社会传统文化和现代文明共存的境况 下,医患矛盾和冲突的发生是社会变革的表象,是文化变迁过程中文化适应的局部表现。希望此论证有益于医 患关系和医患诚信解读。
Based on an analysis about the construction and maintenance of the integrity in Chinese traditional society and western society, we propose that the local culture has an affect on the integrity between medical staff and patients, and there is different integrity culture between patients and medical staff in different society. So in China today where traditional culture and modern civilization coexist, the contradiction and conflict between medical staff and patients is the sign of social revolution and the local manifestation of culture adaptation during culture alterations. We hope that the argument would benefit the improvement of doctor-patient relationship and the interpretation of doctor-patient integrity
三相电压型PWM整流器的级联式非线性PI控制
文杰,林飞,郑琼林
中国电机工程学报 , 2006,
Abstract: 该文以同步旋转坐标系模型为基础,设计了三相电压型PWM整流器的级联式非线性PI控制器。采用双环结构,用三个非线性PI环节实现了对整流器直流电压与功率因数的高性能控制。以误差的非线性函数与传统PI环节构成的级联式控制器,既提高了系统响应的快速性,又增强了抗扰能力,同时计算简单易于实现。与传统PI控制器的仿真对比表明该方法能够明显改善系统的动态性能,而实验结果也验证了非线性PI控制器的优良性能。

文杰,李林,叶文忠
科技进步与对策 , 2009,
Abstract: 创新优势的测度是地区主管部门推动区域产业集群快速发展的重要工作,但目前集群式创新优势测度的指标相对缺乏。在给出集群式创新优势相关概念和内涵的基础之上,识别了集群式创新6个方面的优势。并依据指标选择的条件和设计的原则,以6方面的优势为框架,构建了集群式创新优势测度的指标体系,并进一步给出了具体的评价模型和方法。集群集群式创新评价指标体系模糊综合评价法
应用二次回归旋转正交组合设计提取水溶性苹果多糖的研究
文杰,玉蓉,魏决
食品科学 , 2009,
Abstract: ?采用二次回归正交旋转组合设计方法研究了提取温度、提取时间、料液比对苹果渣中水溶性多糖提取率的影响,确定了苹果多糖的较优提取范围。结果表明,在实验范围内各因素对苹果多糖提取率作用的大小次序为:提取温度>提取时间>料液比;频率分析法得到苹果多糖最优提取工艺为提取温度84℃、提取时间4.1h、料液比1:52(g/ml),在此工艺条件下苹果多糖提取率为14.94%。

数控机床几何误差源的快速辨识方法
Rapid Identification Method for Geometric Errors of CNC Machine Tools

- , 2016, DOI: 10.11784/tdxbz201407079
Abstract: 针对数控机床几何误差源的辨识问题,研究了基于球杆仪测量信息的机床几何误差源快速辨识方法.采用 多项式模型描述机床几何误差源,建立了几何误差源与球杆仪杆长误差之间的线性映射模型.提出一种球杆仪空间 误差检测轨迹,该测量轨迹使得球杆仪仅需一次安装即可实现大范围的空间测量.基于该轨迹上的误差测量数据, 利用岭回归方法辨识出机床几何误差源全集.仿真与实验结果均验证了所提辨识方法的准确性与有效性,基于激光 干涉仪测量方法的验证实验表明,球杆仪辨识结果与激光干涉仪测量结果的偏差在2.3,μm以下.
For the identification issues of machine tools’ geometric errors,a rapid identification method was proposed using double ball-bar(DBB)system. The polynomial model was used to represent geometric errors,and the linear mapping model between geometric errors and DBB length errors was established. Meanwhile,a measurement scheme which required only one installation of the DBB was applied to perform a large space measurement,and ridge regression method was adopted to identify all of the geometric errors. The results of simulation and experiment verify the feasibility and effectiveness of the proposed identification methods,and the deviations between DBB identification results and laser measurement data are less than 2.3,μm
《畜牧兽医学报》创刊50周年回顾与展望
文杰
牲畜兽医学报 , 2006,
Abstract: ?《畜牧兽医学报》是中国科协主管、中国畜牧兽医学会主办的学术性期刊,创刊于1956年7月,现在年出版12期,刊出论文276篇,共计257万字左右,是我国畜牧兽医科研人员重要的学术交流园地。本刊连续入选《中文核心期刊要目总览》,现在已是国内外15家文摘刊物和数据库的文献源。先后获得“全国农学会系统优秀期刊”、北京市新闻出版局“优秀科技期刊编辑质量奖和办刊条件奖”、连续4届获全国畜牧兽医优秀期刊评比一等奖,成为最有影响的畜牧兽医类期刊之一。但与国际知名期刊相比,本刊还有一定差距。为应对国内外期刊竞争的挑战,今后《畜牧兽医学报》应在品牌化、精品化、网络化、国际化等方面下功夫,并强化服务意识,逐步缩小差距,紧跟科技发展的步伐,使本刊早日步入世界优秀期刊行列,为繁荣我国畜牧兽医科技事业做出更大的贡献。
