Investigation of iodine concentration in salt,water and soil along the coast of Zhejiang,China

Objective: We aim to describe the environment iodine concentration in salt, water and soil along Zhejiang Province coast in the China foreland. It will be helpful for us to judge whether this area is insufficient in iodine and universal iodized salt is necessary or not. Methods: We collected iodized salt samples, drinking water samples (tap water in the towns, and well water or spring water in the villages), water samples from different sources (ditches, lakes, rivers) and soil samples through random sampling in June, 2005. Salt, water and soil iodine was detected by arsenic-cerium redox method. Statistical analysis was expressed as mean±SEMby Windows SPSS 13.0. Results: (1) The iodine concentration in salt was 27.9±4.33 mg/kg (n=108). (2) Seventy-five water samples were collected. The water iodine value was 0.6～84.8 μg/L (mean of 11.66 μg/L). The watershed along the Qiantang River has significantly higher iodine content than the water in Lin'an in mountain area (P＜0.01). The iodine content and mean iodine content of tap water, well or spring water and natural water sources were 4.30±2.43 μg/L (n=34), 23.59±27.74 μg/L (n=19)and 12.72±10.72 μg/L (n=22) respectively. This indicated that among environmental water sources, the ditch iodine content was the highest with river water iodine being the lowest (P＜0.01). (3) Soil iodine value was 0.11～2.93 mg/kg (mean of 1.32 mg/kg).Though there was no statistical difference of soil iodine in different districts (P=0.131), soil iodine content correlated positively with water iodine content. Conclusion: Iodine concentration in salt accords with national policy of adding iodine in salt. Foreland has more iodine in water than mountain area. The data reflected that water and soil iodine in foreland area was not high, which suggests universal iodized salt should be necessary. Environment iodine has relatively close association with pollution.     

对现代化教学技术在音乐教学中唯上的批判——兼论教师在音乐教学中的核心作用

在目前的音乐教育课程改革过程中,存在着对现代化教学技术手段的运用“唯上”的误区,如何走出这一误区?广大音乐教师应该有如下的意识:现代化教育技术的运用并不是一节有效音乐课实施的关键所在,音乐教育也不是只有运用了现代化教育技术才能有所作为,而新课程改革的重点更不是落在对现代化教育技术手段的运用上,音乐教师的教学艺术才是成就一堂高质量音乐课的关键因素。     

论科学发展观对宪法及宪法学的影响

科学发展观作为中国特色社会主义理论体系的重要组成部分,所要解决的重大问题是中国的发展模式和发展目的问题。法律作为社会发展模式的一个组成部分,在法治化水平不高或法治模式正在建构的中国,应当顺应发展模式和发展目的的选择,这也为处于转型社会中的中国宪法的发展提供了新的契机。科学发展观具有宪法指导思想价值、宪法性方法论价值、保障基本人权价值。科学发展观将对中国宪法观念变革、宪法内容变化和宪政体制机制完善发生重要影响,将对宪法理论和宪法学体系产生重要影响。     

“双向互动式”英语口语培养模式及绩效研究

针对目前英语口语教学在高职教育中的重要性,辽宁工程技术大学经济管理学院提出了＂双向互动式＂英语口语教学模式及其相应的评估体系。该模式是以口语技能训练为导向,以学生参与为中心,采用了师生互动的教学模式。通过对该模式的绩效研究,证明了该模式与传统的英语口语教学模式相比有着极大的优势。

Fuzzy Comprehensive Assessment Method to Determine Tectonic Stress Patterns

The tectonic stress patterns were determined by a fuzzy comprehensive assessment method. Data of in-situ survey and fault information were utilized in the method. First, by making pressure and tension in the directions of along-river, cross-river, shear clockwise, and shear counterclockwise , 26 types of tectonic stress patterns were presented. And the stress vector of each pattern was obtained with FE software by taking unit displacement as boundary load. Then, by taking the 26 types of tectonic stress patterns as index set and 3 main stresses as factor set and choosing various operators, comparison of directions of computational stress vector and survey stress vector was made and the most possible tectonic stress pattern was obtained. Taking the 26 types of tectonic stress patterns as index set and strike angle as factor set, comparison of relationships between formation of fault and tectonic stress was made,and the tectonic stress patterns were assessed with known fault information. By summarizing the above assessment results, the most impossible tectonic stress pattern was obtained . Finally an engineering case was quoted to validate that the method is more feasible and reliable than traditional empirical method.
