A long-term in situ calibration system for chemistry analysis of seawater

An in situ calibration system is a versatile exploration instrument for electrochemical sensors investigating the biochemical properties of the marine environment. The purpose of this paper is to describe the design of an auto-calibrating system for electrochemical （pH） sensors, which permits two-point in situ calibration, suitable for long-term measurement in deep sea aqueous environments. Holding multiple sensors, the instrument is designed to perform long-term measurements and in situ calibrations at abyssal depth （up to 4000 m）. The instrument is composed of a compact fluid control system which is pressure-equilibrated and designed for deep-sea operation. In situ calibration capability plays a key role in the quality and reproducibility of the data. This paper focuses on methods for extending the lifetime of the instrument, considering the fluidics design, mechanical design, and low-power consumption of the electronics controller. The instrument can last 46 d under normal operating conditions, fulfilling the need for long-term operation. Data concerning pH measured during the KNOX18RR cruise （Mid-Atlantic Ridge, July-August, 2008） illustrate the desirable properties of the instrument. Combined with different electrodes （pH, H2, H2S, etc.）, it should be of great utility for the study of deep ocean environments, including water column and diffuse-flow hydrothermal fluids.

从《孤独者》看鲁迅小说的对话性

本文从巴赫金的复调小说理论出发,着重分析了<孤独者>文本话语的对话性特征.在叙述者、主人公各自的话语内部以及他们之间都存在着对话性,形成了巴赫金所说的"微型对话"和"大型对话".而且,在结构的构制上也存在着对话性.这种对话性体现了鲁迅思想的复杂性,也体现了五四时期话语的多样混杂的状况对鲁迅的影响.从对话性入手,从而能更好地理解鲁迅的小说以及小说背后的精神世界.     

从"宏大叙事"到"叙事游戏"--《人到中年》和《冈底斯的诱惑》的比较

《人到中年》和《冈底斯的诱惑》这两个文本是处于新时期两个重要时间点的重要作品.从其创作方法、小说观念的异同中,我们可以看到新时期文学从意识形态普遍化到反抗意识形态,从寻找历史主体到个人化写作,从"写什么"到"怎么写"的嬗变轨迹.     

寻根探源说“不”“无”

不"和"无",是汉语中词性不同但使用时又有相同点的两个实词。拟从根源上对其进行探究,以便更充分地认识它们,更准确地使用它们。     

Promoting inclusive education in secondary school in Norway: a national programme for teacher development

There is a great need in many countries for extended and new teacher competence to meet the challenges of inclusive education. This paper presents a national programme for developing new teacher competence in secondary schools in Norway. The programme was developed and implemented during the 1990s, its aim being to start a continuing process in schools directed at promoting inclusive education and improving the quality of education for pupils with special educational needs. Further, the paper presents some findings from a national survey of 2240 teachers and school administrators in 104 schools one year after the implementation of the programme. The survey partially replicated a survey carried out before the programme started. The purpose was to give an overall picture of the situation with respect to teacher competence in special needs and inclusive education, and the impact of the competence building programme on teacher practice, and to identify possible system changes in schools.     

2008年世界与中国田径成绩比较的灰色预测

应用灰色系统的GM(1,1)模型群和等维灰数递补法,预测2008年世界田径第3名和第10名的成绩以及中国2008年田径最好成绩,通过比较,认为2008年中国田径男子在110m栏、跳高、撑杆跳高、三级跳远以及女子400m栏、跳远有望进入世界前3名;男子铁饼、标枪和女子铅球、铁饼、标枪可能挤进世界前10名.可以为决策者制定科学的奥运发展战略提供依据,并对于制定田径项目的训练计划和进行科学训练有一定的参考价值.

重新思考民族生存与民族文化的关系——从《怀念振铎》论及巴金晚年有关民族文化的反思

《怀念振铎》是巴金晚年最后一篇文章,文中所谈,虽然是朋友交往的细事,但其中也包含了他对自己一生观点的认真思考。本文从巴金对自己早年对郑振铎的批评的反省谈起,深入分析了五四精神的内在矛盾,指出“激进地反传统”的那一代知识分子,在有关民族生存和民族文化绵延问题上,不可避免地面对着的思想困境;并进而论析了时代变化,尤其是“文革”经历,和新的世界文化视野,在他们思想转变中的重要作用。
