思想政治教育融入城市型、应用型大学英语教学的有效路径探析

将思想政治教育融入大学英语教学是新形势下对大学英语教师提出的要求。城市型、应用型大学英语教师应切实认识到语言传递意识形态的本质,深刻领会思想政治教育宽泛的育人内涵。从教学大纲修订环节入手,开发编写包含思想政治教育内容的教材及讲义。大学英语教师在英语教学过程中应该采取多种教学方法,从爱国主义、人格品质、理想信念、中国文化等方面对学生进行思想政治教育,帮助他们树立社会主义核心价值观,培养出符合城市型、应用型大学培养目标的合格人才。     

弘扬方志敏精神与社会主义核心价值观的践行传承

在八一精神的感召下，方志敏领导发动了赣东北的弋横暴动，在艰苦的革命斗争实践中形成了“爱国、创造、清贫、奉献”的方志敏精神，体现了“爱国、自由、平等、公正”的思想。当前我国正在进行“四个”方面建设，继承并弘扬方志敏精神，对践行社会主义核心价值观，树立和发扬以爱国主义为核心的民族精神和以改革创新为核心的时代精神，有着重要的现实意义。

Distribution of correlation dimensions of synchronous 12-lead ECG signals

Correlation dimensionsD ₂ of the synchronous 12-lead ECG signals have been investigated for the first time by distributed multi-sensor (multi-electrode) technique. The results show that correlation dimension of heart has the distributed characteristics.D ₂ calculated from different lead ECG signals is not a constant regardless of a healthy person or a coronary heart disease (CHD) patient with sinus rhythm. But with the same lead signal,D ₂ of CHD patients is evidently smaller than that of a healthy person except I, II, III leads. A healthy person and CHD patient can be identified byD ₂ statistically andD ₂ shows the potential application in the diagnosis of the CHD patients.

Design and fabrication of 1-D semiconductor nanomaterials for high-performance photovoltaics

To date, the cost-effective utilization of solar energy by photovoltaics for large-scale deployment remains challenging. Further cost minimization and efficiency maximization, through reduction of material consumption, simplification of device fabrication as well as optimization of device structure and geometry, are required. The usage of 1D nanomaterials is attractive due to the outstanding light coupling effect, the ease of fabrication, and integration with one-dimensional(1-D) semiconductor materials. The light absorption efficiency can be enhanced significantly, and the corresponding light-toelectricity conversion efficiency can be as high as their bulk counterparts. Also, the amount of active materials used can be reduced. This review summarizes the recent development of 1-D nanomaterials for photovoltaic applications, including the anti-reflection, the light absorption,the minority diffusion, and the semiconductor junction properties. With solid progress and prospect shown in the past 10 years, 1-D semiconductor nanomaterials are attractive and promising for the realization of high-efficiency and low-cost solar cells.
