让《语文读本》走出“深闺”

学生步入高中后，很多语教师都会强调要增加课外阅读量，并且也会给学生一蝗切实的建议。这是尤叮厚非的，囚为本来就是“得法于课内，得益于课外”。但我在具体的教学实践中发现，教师的初衷是好的，实践起来却由于以下几个原因而效果不佳。     

运动技术训练手段量最优分配方案的实现

作者在[1]总共用贴近度的方法对在技术训练中如何进行控制训练,做了初步的讨论,结果不够理想.原因是它属于一种近似解.为了寻找训练手段量最优分配方案的实现,作者在本文中用求解模糊关系方程的方法,获得了这一问题的最终解决,也是对作者[1]中的结果进一步深化.因此,让机器来代替教练员的工作,模糊运动技术训练的安排,成为人工智能中的专家咨询系统,完全有可能变成现实.     

论写境与造境

王国维将意境分为写境与造境两种形态，却未作具体阐述。现代研究者对它们也未作深入的探讨。对此，本文从审美的角度来探讨写境和造境的艺术特征，认为写境具有真实性、客观性和自然之美；造境具有主观抒情性、表意性和理想化抒情手法等。写境有画境、物境、事境等类型；造境有缘情写镜、直抒胸臆、象征虚幻等形态。     

液态易挥发性试剂在实验应用中的污染防治

液态易挥发性试剂在用量筒量取和配制时，会因试剂强烈挥发而造成空气污染，使用滴管、移液管和带刻度烧杯等其他器皿甚至废旧空瓶替代就可大大减少试剂的挥发。     

量的名称及表示（2）

1．2 量符号 量符号书写与使用，需要注意以下几点：1．量符号必须使用斜体字母，矢量和张量还应使用黑斜体；仅有pH用正体。     

理科综合总复习指要

一、基础知识要夯实 理科综合测试卷最鲜明的特点就是基础性,基础知识是高考的首要依据,基础不扎实是考试失分的首要原因.理、化、生三科综合在一起知识面广,题量大,而答题的时间有限,所以三科综合考查必然是突出对基础知识的考查.具体说来就是--以考试大纲为依据,同时不拘泥于教材内容,要求同学们做到五个能:①能清楚地复述所学的基本概念、基本规律、基本原理和基本观点;②能对重点概念、原理和观点进行分解和综合;③能梳理教材的知识体系,揭示重点知识之间的内在联系;④能比较、分析同类型知识的差异;⑤能运用所学知识分析、解决实际问题.     

水合高碘酸镉盐溶解反应的热力学性质

用恒温热量计测定了 Cd2 HIO6 · 1 .2 5 H2 O在 3 mol· dm- 3HNO3水溶液中的标准摩尔溶解焓变 ,计算出了相应的标准摩尔自由能变与标准摩尔熵变 .用线性回归法分析并修正了用分光光度计在 2 98.5～ 3 2 8K范围内测定与计算的文献值     

关于Runge－－Lenz矢量的方向和大小的讨论

描述行星规律的R-L矢量在笔者所见的文献中只指出了它的方向但末证明，本文对其加以了证明；并在此基础上比较简略地计算了它的大小；进而讨论了它的物理意义。     

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.
